Genetics and Health: Why Diet and Movement Matter

in ,

The other day I received an email from a good friend and client sharing a link to an article in the NY Times. The article discusses a recent study done with participants from an earlier study, completed in 2003, on the effects of exercise. This earlier study, done at Duke University and called “STRRIDE” (for Studies Targeting Risk Reduction Interventions through Defined Exercise), took several hundred individuals identified as sedentary and overweight and randomly assigned them to either a control group or one of two exercise groups. The two exercise groups included one that did “moderate” exercise, such as walking, and one that did “vigorous” exercise such as jogging. The exercise groups did their assigned exercise for 8 months. The control group did not exercise at all.

As you might expect, both exercise groups showed marked improvement in several health markers including aerobic fitness, blood pressure, insulin sensitivity and waist circumference, while the control group generally showed no improvement. For this recent study individuals from each of the groups were invited back to the lab for testing to see how they were faring. Those that agreed to come back were tested for aerobic capacity and metabolic health and were asked about their health conditions and medications.

Not surprisingly, those from the control group in the original study were even less fit now than they were in 2003 while those from either exercise group were still better off than the control group. Less obvious but still not surprising was the fact that those who had done “vigorous” exercise in the earlier study showed greater aerobic capacity than those in either the “moderate” exercise group or the control, losing on average only 5% vs. a 10% loss in the other two groups.

But what was very surprising to these scientists was that the “moderate” exercise group, who had only walked 3 times a week for 8 months during the earlier study, showed substantial improvement in blood pressure and insulin sensitivity compared with both the “vigorous” exercise group and the control group. NOW THIS IS THE MOST INTERESTING PART – these walkers also showed these lasting improvements to their health EVEN IF THEY HAD STOPPED WALKING AFTER THE 8 MONTHS! William Kraus, the professor of medicine and cardiology at Duke who oversaw the study suggested that the effect of exercise on our genes and our cells might explain the study’s findings.

I regularly have conversations with clients who ask me “is this problem something I can do something about or is just my age?” I always encourage clients to avoid chalking up problems to age, even if age might be a factor, because once we decide that some pain or loss of function is due to age then it places that issue into the category of “PROBLEMS I CAN’T DO ANYTHING ABOUT.” Once a health issue is put in this category it robs us of the capacity and motivation to do anything to improve it, and there’s just about always something we can do to make things better.

I see deferring to genetics in a similar way. If we make the assumption that a health issue we have or might develop is due to our genes, even if our mother or father did have the same condition, then it hampers our ability to deal with it in the same way that saying a problem is “just because I’m getting old” does. As long as the problem is under the “CAN’T DO ANYTHING ABOUT IT” umbrella then we’re unlikely to respond effectively.

Studies demonstrate, and pretty consistently I might add, that the health issues that most of us are dealing with or that we are most concerned about are caused by genetics only about 10 to 30 percent of the time. The other 70 to 90 percent of the time these health issues are caused by diet and lifestyle. Cardiovascular disease and diabetes in particular have been shown to manifest much more from lifestyle causes than from any genetic predisposition. Not only that, but it’s also been demonstrated that changes in lifestyle can influence our genetics so as to increase our genetic resistance to a chronic diseases such as cancer.

A 2016 pilot study done at The University of California San Francisco revealed that men with low risk prostate cancer who had decided to forgo treatment unless the disease progressed could improve the genetic markers for cancer by changing their diet. These men followed a diet outlined by Dr. Dean Ornish, and the men who followed this diet for 3 months saw some 500 genes change as a result. This included some tumor-suppressing genes that became more active with the change in diet, as well as some genes associated with increasing cancer risk that had switched off. The study did not set out to determine whether or not the changes in diet led to better long term health outcomes, but the changes in these men’s genetics were significant and promising.

Clearly our dietary choices are a powerful force for influencing our genes and any contribution those genes might make toward our manifesting a health problem, but what about our lifestyle choices? In her groundbreaking book, Move Your DNA, Katy Bowman argues for lifestyle, in the form of our daily movements, as a huge contributor to the health of our genes and their expression. She illuminates the important role of movement in gene expression by highlighting the difference between the genome and the mechanome.

The genome is the gene that we tend to think about when we think of our genes. This is the gene that resides with all our other genes in the nucleus of each and every one of our cells. This gene expresses itself by activating certain physical and/or functional characteristics that make us who we are as an individual. The mechanome is made up of this gene plus all of the exterior forces, many of them mechanical, that play a role in determining if and how a particular genome will be expressed.

To think of a gene as the primary actor in determining our health outcomes is like imagining some kind of stealth bomb in our body that will some day, likely when we least expect it, set off its charge and send us cascading toward some miserable end. Alternatively, the mechanome model presents a gene that is flexible and responsive to input, particularly movement input, and one that can, given the right input, just as easily contribute to a positive health outcome as a negative one. Therefore the amount and way we move, both a huge part of our lifestyle choices, can be a significant influence on our genes and how they influence our health and longevity.

Movement choices are like the dietary choices we make in that they provides us with yet another powerful tool by which to influence our health on the genetic level. In a recent post on yoga for health I discussed the role of mechanotransduction in movement and I describe how movement can be used to influence tissue health on the cellular level. Although I highlight yoga specifically in that article, yoga is just one example of an approach to movement that provides effective ways of using mechanotransduction to affect tissue health. Yoga is intelligent movement, but there are other ways of moving intelligently that can have similar benefits. Walking for instance, appears to have played a significant positive role in the gene expression of the “moderate” exercisers in the “STRRIDE” study discussed above.

It should be encouraging to all of us, and especially those of us who worry that our genetic makeup may be undermining our health and function, that the studies mentioned above show we can improve our chances of better health outcomes with diet and exercise / movement, even if we have genetic predispositions. These studies reveal that we needn’t be at the mercy of our genes and that we have it within our power to change our genes in ways that are positive and lasting.

 

A Case for Yoga: Improving Strength, Mobility and Overall Health

in , , , ,

As a yoga teacher I’ve been advocating for a proactive effort to increase flexibility in the body for more than 2 decades. Yoga is generally seen these days as a valid way of increasing flexibility, but not necessarily one that offers the complete complement of physical benefits regarded as essential for overall health and wellness. For instance, many yoga students feel they need to engage in other activities for cardiovascular exercise, such as spinning, Zumba or running, to keep themselves healthy. Yoga, it appears for these folks, is not enough.

A decade or so ago when yoga was still “the new kid on the block” in the fitness industry, it enjoyed a sort of “cure for everything” status that temporarily shielded it from the responsibility to deliver on that promise. Now that yoga has slipped from it’s peak of popularity into the ever expanding menu of fitness options, it is held to the same standards that other types of “exercise” are and its strengths are weaknesses as an exercise form, depending on the type of yoga or the skill level of the instructor, have become more commonly known and accepted.

One strength of yoga that appears to be gaining ground in the scientific community and with the public is its efficacy in reducing the effects of stress and as a contributing factor to overall health and well being. A 2012 National Health Interview Survey (NHIS) found that, among the people surveyed who practiced yoga, 94% said they did so for “wellness-related reasons – such as general wellness/disease prevention or to improve energy,” with 82% of the respondents saying that it “improved their overall health” and 86% saying yoga reduced their stress.

I should point out here that the benefits of yoga reported above, along with other benefits reported for its positive effects on back pain, sleep, menopause, diabetes and other chronic disease and weight loss are mainly anecdotal. There is limited scientific support for nearly all of the claims made in yoga magazines and websites. But for some of these claims, such as yoga’s efficacy in building strength, the benefits are clear and undeniable.

The fact is, yoga postures done correctly place mechanical loads on our muscles, ligaments and bones in controlled and specific ways, and this type of loading, as dictated by the laws of our physical universe and the biological nature of our tissue, increases the load bearing capacity (ie- strength) of these tissues quite effectively. Without a doubt, yoga makes us stronger.

So if there is at least some evidence, even though mostly anecdotal, that yoga is good for stress reduction and overall health and well being, and clear evidence that yoga can be an effective way of building strength, then I would argue that latter is closely related to the former. The fact that yoga helps build strength is the reason that it helps with stress reduction and overall health.

This is because our overall health is largely defined by the health of our tissues. What are we but a highly complex arrangement of tissues and extra-cellular fluid (leaving aside the mind and the soul which are a subject for another time). We cannot be healthy and have a significant amount of unhealthy tissue in our body. Conversely, our overall level of tissue health is directly related to our overall health in general. The healthier our tissue is, the healthier we are.

So what exactly does strength have to do with tissue health? The answer lies in understanding our tissues on both macro and microcosmic levels. If for instance I want to strengthen my legs and hips I might choose to do more standing postures. The mechanical loads these postures place on the muscles and other tissues in my legs and hips will help these tissues handle loads better, thereby making them stronger. But what happens to the individual cells in the various tissues in my legs? I would argue that these same postures also improve the strength of the individual cells in the tissues that make up my legs and hips. This is due to a phenomenon knowns as mechanotransduction.

Mechanotransduction occurs when a mechanical stimulus is converted into a set of biochemical reactions and corresponding a cellular response. This cellular response can vary depending on the type of cell and stimulus, but generally involves enhanced gene expression and positive physical changes to the cell. Scientifically, mechanotransduction is a concept still in its infancy in terms of study and understanding, but the studies that have been done suggest that mechanical loads on the microcosmic level mimic those on the macrocosmic. That is, mechanical loads that make our muscles and bones stronger also make our cells “stronger” in the sense that they improve their adaptiveness and enhance their functional role in our bodies.

Therefore I’d suggest that “weight bearing exercise”, which is basically deliberate mechanical loading of our tissues, not only has the potential to build strength and resiliency in that tissue but also, as a result of mechanotransduction, similarly loads our cells and stimulates greater responsiveness and resiliency on the cellular level, improving the health of those cells, the tissues they make up and our overall health in general.

I place “weight bearing exercise” in quotations here because it can and does mean more than it’s common interpretation suggests. Sitting for example, can be a kind of “weight bearing exercise” in the sense that it places mechanical loads on the tissues of our hips and legs and, if done in the right way, has the potential to make them stronger and more resilient. On the other hand, sitting can and often is counterproductive in this regard because it is not done in the right way, or is done for too long, and will in this case damage tissue health by limiting mechanotranscduction and impairing tissue health.

This brings me back to the importance of flexibility, or as I prefer to think of it, mobility. Having good flexibility means having functional mobility which is the ability to mobilize the body in a variety of ways. Mobility allows me to move more of my joints and tissues through their various ranges of motion and this means a wider and more varied distribution of mechanical loads to more of my tissues. A major benefit of mobility therefore is the stimulation of mechano-transduction in more of the cells in more of my tissues and an improvement in the healthful expression of those cells and those tissues. Floor sitting done properly, for example, can be and effective way of improving the mobility of the hips, knees and ankles and can therefore promote the health of the tissues in the lower half of the body.

A less obvious benefit to functional mobility is the enhancement of my cardiovascular system. Improved and varied mobility of the body generally improves the mobility and more specifically the elasticity of my arterial system, helping to normalize blood pressure and reduce the effects of various types of stress on vessel walls. This particular benefit of functional mobility, which incidentally is facilitated rather well by regular and correct practice of yoga, improves the responsiveness and resiliency of my cardiovascular system and prevents chronic diseases related to it.

I’ve tried here to make a case for yoga as having the potential to be as complete as any other form of “exercise” for promoting and maintaining health. It’s reputation for helping mainly with flexibility and stress is a very limited view that fails to tell the whole story of its full potential. This potential, to literally enhance and maintain our tissue health on the cellular level, is open to anyone willing to spend the time and energy to learn it.

Guided Relaxation (Shavasana)

in , ,

This is a long time coming. I’ve had students asking me for a recording of my guided shavasana for at least a decade. For those of you who’ve been asking for it, I hope it was worth the wait.

For those of you who are non-yogi’s, this recording is basically a guided relaxation. Before starting the audio, lie in an appropriate position. If you’re not sure which position to lie in, I can recommend Psoas Release on a Bolster. You can watch a video demonstration of this posture here.

As this is my first try on recording a guided relaxation, I am aware that there is plenty of room for improvement. I welcome your feedback!

STRENGTH TRAIN YOUR NERVOUS SYSTEM – Health and the Autonomic N.S.

in , , ,

Your autonomic nervous system is composed of two parts – the sympathetic and the parasympathetic nervous systems.  The sympathetic is the body’s accelerator or stimulator, increasing muscle contraction, heart rate and blood flow.  The parasympathetic is the resting aspect of this system and promotes muscular relaxation, slowing of the heart rate and relaxation of blood vessel walls.

When the autonomic nervous system is in “good shape” it transitions easily between these component systems and their functions  at the appropriate times. This ability to transition from the “fight or flight” response of the sympathetic N.S. and the “rest & digest” response of the parasympathetic is akin to a dimmer on a light switch that increases and intensifies the light when more light is needed to see and concentrate and then dials down the light, perhaps later that evening, for a romantic, candle light dinner.  Thus a well functioning autonomic N.S. gives us the ability to react quickly and forcefully to a dangerous situation at one moment, then relax and rest, maybe even take a quick nap and wake up refreshed a while later.

This aspect of our nervous system is called “autonomic” because its functions can operate without our having to think about them.  At the same time,  the autonomic  N.S. allows for a certain degree of conscious control. A great example of this is the role of the autonomic N.S. in respiration. We typically breathe without thinking about it,(thankfully) but we do have the ability to speed up or slow down our breathing at will and ideally with relative speed and ease. So despite the fact that many of our autonomic functions can occur unconsciously, we do have the ability to affect these functions consciously and therefore we can practice or “train” this part of our nervous system to perform its functions better.

A strong autonomic nervous system intelligently uses aspects of both the sympathetic and parasympathetic and is able to switch gears when needed without taxing the body.  We can consciously train our nervous system to seamlessly make this shift between stimulation and relaxation, and this will help keep our cardiovascular system strong and supple and facilitate muscle recovery. Thus “training” our autonomic N.S. not only improves the health of our nervous system but also the health of our muscles and cardiovascular system.

Most modern humans spend significant time  in situations and engaged in activities that stimulate the sympathetic nervous system to a mild degree.  This constant low-grade stimulation can become a habit, leading to missed cues that our body is neither resting nor fully engaged.  It’s as though we forget our light switch has a dimmer and leave the light on at the same brightness constantly, no matter the time of day or need for more or less light.

This “sympathetic overdrive” is also like a car running at idle, occasionally revving  the engine but never actually driving anywhere and never completely shutting off.  This can happen to all of us occasionally, and its not a big problem until it begins to manifest consistently when it will weaken our nervous system and its ability to shift from the sympathetic N.S. to the parasympathetic and it’s important functions.

Some signs of sympathetic overdrive include:

  • Digestive problems
  • Sleep problems
  • fatigue, exhaustion
  • shallow breathing
  • moodiness, anger, upset easily
  • high muscle tension
  • muscle pain
  • frequent colds or easily getting sick
  • metabolic disorders
  • high blood pressure
  • blood vessel problems

To train your nervous system to be adaptable and functioning optimally, here are some key steps:

1) Breathe diaphragmatically all the time

Diaphragmatic breathing is the easiest way to turn on the parasympathetic response. When you breathe well, your shoulders relax, your whole abdominal wall gently expands 360 degrees and there is a slight pause between the inhale and exhale.

Signs of breathing dysfunction include:

  • Spending your day sitting with a rounded back
  • Lifting your chest or shoulders up while inhaling
  • A chronically stiff and tight upper back
  • Breathing in and out of your mouth
  • Yawning or sighing frequently
  • A resting respiration rate higher than 12 breathes a minute

Your diaphragm is one of your largest back muscles.  In order to draw air into the deepest part of the lungs, it has to contract during inhalation. This contraction is a downward movement and in order for it to move down, the abdominal wall has to expand.  This is virtually impossible to do if you are slouching.  Conversely, correcting a slouch with a military style posture of arching the back and pulling the shoulder blades together will also restrict the movement of the diaphragm and interfere with breathing.

See our earlier blog post on diaphragmatic breathing for more on this subject.

2) Learn to relax the body

Our muscles are designed to do two things very well- contract and relax. Consciously relaxing our muscles helps them to contract more easily.  A muscle that forgets to relax is more prone to strain, pain and adds to overall discomfort in the body. Training your muscles to relax is just as important as doing your daily workout at the gym.

Some techniques that help include:

  • massage
  • yoga
  • tai chi / chi gung
  • biofeedback
  • meditation
  • warm baths.

Try giving yourself permission to relax and rest in small chunks throughout the day. Also, check out this video showing a great way of relaxing the psoas muscle. It will help you remember how to let go of tension in the body and the nervous system.

3) Learn to relax the mind

The workings of the mind distract us from being in our body and hence being able to perceive the habits that contribute to sympathetic over-stimulation. Habits like holding our breath, tensing parts of our bodies, straining our eyes and getting frustrated with little things often manifest as result of tension in the mind. Taking a few minutes every day to let the mind relax is renewing and refreshing to the body.

My favorite way to do this is to sit or lie down in a quiet area, scan through my body to note areas of tension, visualize the tension melting with the image of sunlight and then letting my mind be free. Letting the mind be free is as simple as giving permission for your thoughts be free of any particular focus.

4) Exercise on a regular basis with a large variety of challenges.

Your exercise should be varied and daily.  Each day should include walking, weight resistance, stretches and movements that challenge your balance and your movement skills.  The more muscles you use, the more blood flow you will have and this increased blood flow will feed nerves and removes waste products from all of your tissues. Stimulating the nerves meanwhile builds their resilience and adaptability.

*Personal Alignment Training is ideal for training the nervous system along with muscles, bones, joints and the C.V. system!

5) Get deep rest

How many times have you felt ready for bed at 8pm but for various reasons, ignore the signals?

Try this experiment once a week:

Forgo TV after dinner and read something relaxing, like a good book (not the news). Dim the lights in your home after the sun sets. Adjust the light so its just bright enough to read. Put away your phone and computer- you can check them in the in the morning. Notice when your body starts to send the signals it is ready for bed (not the mind!).

Place no significance on the time…

Just go to bed…

…and notice how much more rested you feel the next day!

If you have ever been camping you are likely familiar with this type of letting go.

6) Spend time in nature

Being outdoors is very soothing to the nervous system.  Exposure to the natural colors of blue and green have been shown to calm to our sensory nerves.

Try getting outdoors more on your lunch break.

Or instead of going to the gym, do a hike instead.  Exercising outdoors will engage the nervous system differently than an indoor workout with all of its distractions.

7) Be mindful of the quantity of stimulants you are consuming

Caffeine causes your blood vessels to restrict which can result in more muscular tension. Coffee and tea are delicious and enjoyable but consuming more than 1-2 cups a day or having caffeine after lunch can interfere with your body’s ability to relax and get a good night’s sleep. For anyone struggling with sleep issues, I recommend slowly reducing your intake to 1 cup a day and perhaps switching to tea most days as it contains less caffeine and delivers it more gradually.

A well functioning autonomic N.S. is essential to our long term health and quality of life. These “training” tips will help you build a stronger, more resilient nervous system that will serve you now and for years to come!

Adaptation and the Psoas

in , , , ,

When we’re faced with pain it’s easy to wonder, “why did this happen to me?” Seeking a cause for pain can be helpful, but only if we’re willing to consider the possibility that the pain is the result of how we’ve been using our body, or in many cases, not using it.

Human beings as a species have been successful on this planet largely due to our uncanny ability to adapt to our environment. Our bodies are extremely well adapted to the hunter gatherer lifestyle of our distant ancestors, for example, and like these ancestors we thrive on a wide variety of foods and the great number of human movements once required to collect them.

The breakneck pace of technology, however, has placed great demands on our ability to adapt to changes in diet and lifestyle. With very high calorie foods so easy to come by with so little physical effort, even relatively young people must all guard against diseases unheard of in the few hunter gatherer populations still remaining on this planet.

Perhaps the solution is getting more exercise, but this is highly debatable. The true purpose of exercise is to provide a substitute for the movement we’re not doing and the calories we’re not using in our increasingly technologically driven and sedentary modern lifestyle, but most of what we do for exercise these days reinforces the very lifestyle habits we’re already spending most of our days doing. Is sitting on a bike pedaling for an hour better than siting still in a chair? Maybe a bit, but it’s still sitting and can still contribute to many of the same health consequences.

In her 2015 book Don’t Just Sit There, Katy Bowman speaks to this issue when she says “the sitting itself isn’t really the problem, it is the repetitive use of a single position than makes us literally become ill in a litany of ways.” She goes on to give several examples including that “muscles will adapt to repetitive positioning by changing their cellular makeup, which in turn leads to less joint range of motion.”

I find myself telling my clients and students constantly that muscles adapt to the position we put our bones in. For instance If I stand with my hip joints forward of my knees and ankles, my hamstrings and calve muscles will shorten, limiting my ability to bend forward from my hips and placing greater demands on muscles and joints in my lower back.

These “adaptive” changes manifest to a certain extent over a period of time, but in some cases this type of adaptation can be very quick, even instantaneous. In the hips forward misalignment described above, the affects on muscle length and range of motion can actually happen rather quickly. Standing with the hips pushed forward turns off the muscles in the posterior hip and lower back. This doesn’t take any time at all, it simply happens as a result of doing it.

This turning off of the hip muscles is also a kind of adaptation and I actually consider this good news for us modern humans. It demonstrates that our bodies have the ability to make some changes rather quickly and that these changes can just as easily be good for our health and function as bad.

My favorite example of soliciting a positive change in the body that can have huge benefits to our health and function is what happens in the Psoas Release. I use this posture as much as any I teach my students and clients because I’ve seen how effective it can be in retuning the psoas muscles to a more functional length. This is important as psoas that are too short have a huge impact on our health and function in a variety of ways.

The psoas muscles are rather large muscles that attaches to the inner, upper femur at one end and to a number of locations along the lumbar spine at the other. The psoas run through the pelvis but do not attach directly to it. The psoas do however have a big impact on the alignment of the pelvis as well as the alignment of the lumbar spine. One impact they can have on the pelvis is the very misalignment pattern described above – causing the hips (and the pelvis along with them) to sit forward of the knees and ankles and therefore shortened psoas can directly contribute to limited hip strength and limited hip range of motion.

Other possible effects of short psoas muscles are numerous. Here are a few more:

  • Compression of the lumbar discs
  • Excessive load on the sacroilliac joints
  • Increased risk of sciatica
  • Restriction of the diaphragm and disruption of healthy respiratory function
  • Inhibition of the pelvic floor tone
  • Increased risk of high blood pressure
  • Decreased circulation through the abdominal aorta
  • Impairment of the digestive system
  • Impairment of the urinary system
  • Impairment of the reproductive system
  • Ongoing activation of the sympathetic nervous system

Clearly there are a number of compelling reasons for have a longer, more functional psoas. So let’s look at the Psoas Release and learn a rather simple, gentle and effective way of bringing the psoas back to a more functional length. And did I mention that this pose can be very relaxing?

Understanding Allergies Better for More Relief

in , ,

As the weather heats up I find that myself and others are experiencing more difficulties with allergies. Symptoms of sinus irritation, itchy eyes, sneezing and congestion that were less a problem when the weather was cooler tend to increase as the temperature rises. It reminds me to do the things I know I need to do to keep a clear head.

Years ago, before I had much interest in alternative health or even health in general for that matter, I was at an event out in an open field east of Sacramento in the summer. I don’t remember why I was there, but I do remember very clearly that I was suffering. My eyes and nose were on fire and I could not stop sneezing. I was miserable.

A gentleman at the event saw the state I was in and told me a story. He said that there was a time when he would have been suffering the way I was, but that he saw an allergy doctor that helped him. This doctor tested him for sensitivities to a variety of substances ranging from environmental irritants to household chemicals to various foods. After the tests the doctor revealed to him those substances to which he was most sensitive and pointed out that one of these was tomatoes. The doctor told him that if he stopped eating tomatoes he would see a significant improvement in his symptoms. The man followed this adivce and his allergies cleared up.

It’s fascinating to me that a relatively minor change in diet could have had such a huge impact on this man’s allergies. I come back to this story periodically and it reminds me that we all have things to which we’re sensitive and many of them, like environmental irritants or pollutants, we really can’t totally avoid. But despite the pervasiveness of many irritants in our environment, what we eat can still has a significant impact on allergies.

We had a rainy winter and plants are still vital and abundant and many of these plants produce pollens that can be irritating to our tissues and solicit reactions from those tissues in the form of allergy symptoms. Staying indoors when our allergy symptoms are at their worst is an option, but not a long term one and not one that avoids exposure altogether.

Most people I talk to who have seasonal allergies use over the counter medications to manage symptoms until these symptoms pass. Examples include steroidal nasal sprays such as Flonase that reduce irritation to the sinuses and anti-histamines such as Claritin and Allegra that prevent our bodies from producing more histamines, the chemicals our cells produce in response to a pathogen.

I am in no way against using these medicines to relieve symptoms and if I’m really suffering I have no problem getting out my stash of Flonase. But I also believe we shouldn’t limit ourselves to merely treating symptoms. It is within our power to limit our exposure to other irritants, such as those in our diet, and by doing so we can reduce our tendency to react to the irritants we can’t avoid.

Ayurveda has helped me see the tremendous value in understanding and addressing root causes of ill health and has exposed me to effective alternatives to symptom treatment. Ayurveda is a terrific source of “home remedies” or using common, easily available household items or methods to treat common ailments. I’ve found that trying out many of these remedies has given me a deeper understanding of how health problems manifest and made me more effective in making recommendations to clients.

Ayurveda views allergies as being a symptom of defective or deficient agni. The word “agni” means “fire,” and it refers to the digestive fire or the ability of a person or of a particular tissue in a person to break down and assimilate or neutralize a substance. If the agni is weak or not working right then a person or tissue will struggle with the metabolic process, resulting in the production of toxins rather than the production of more healthy tissue. If these toxins accumulate they further depress the agni which may eventually trigger an immune response in the form of an allergic reaction.

Thus an essential part of Ayurvedic treatment and prevention of allergies is to improve agni. Our main agni is our digestive agni and one way we can strengthen it is by avoiding foods that are heavy and/or difficult to digest. Foods high in refined sugar are the low hanging fruit for elimination as they greatly tax the agni and have been shown to dramatically depress our immune system. A 1973 study done at Loma Linda University showed that ingesting 100g of sugar, about the amount in 1 liter of soda, reduced the germ fighting capacity of white blood cells by 40%, and this effect lasted for up to 5 hours!

Another way we can strengthen agni is to use an appropriate herbal digestive. A simple one that will work for most people is a tea made from a decoction of cumin, coriander and fennel.

Boil 1 tsp each of cumin, coriander and fennel seeds (whole not powdered) in 3 cups of water down to 2 cups and sip this tea with meals.

“CCF Tea” will help to strengthen weak agni and regulate agni that is over active. Keeping our agni optimal helps us digest and assimilate our food better and prevents us from producing and accumulating the digestive related toxicity that can put a drag on our immune system and increase our allergy symptoms.

Besides taking the above steps to keep our agni strong and our digestion working well I also find neti- a nasal saline rinse – helpful for relieving allergy symptoms. Many people know about nasal saline rinsing as it’s often recommended by docotors for allergies and colds. In the case of allergies, rinsing the sinus passages with salt water helps clear irritants out of the sinus passages, thereby reducing our exposure to these irritants and our tendency to react to them. There are different ways to do a saline rinse, but my favorite and the one I recommend most is using a neti pot.

Depending on the size of the neti pot, dissolve 1/4 to 1/2 tsp of fine sea salt into boiled, body temperature water. Taste the water for saline content. It should have the salinity of your tears. Place the water into the pot and place the spout of the pot into your right nostril. Tilt the head down and to the left over the sink until the water flows into your right nostril and out of your left. Remember to breathe through your mouth.

For larger pots, use half of the water to pour from right to left and the other half to pour from left to right. For smaller pots use a full pot in each direction. When you’ve finished each side, gently blow the excess water out. Be careful not to blow so hard and to push the water deeper into your sinuses.

While Ayurveda recommends neti it goes a step further. This step, done after the rinse and when the saline solution has been gently blown out of the nose, is to apply sesame oil, coconut oil or a combination of the two to the inside of the nose.

Take a small amount of liquified coconut or sesame oil into your palm. Dip your small finger or a cue tip into the oil and apply it to your nostrils. Sniff a few times to pull the oil deeper into the nasal passages. If you have time, lie down for a few minutes with the head comfortably back to allow the oil to drain in more.

Oil will help to counter the dryness caused by weather and/or the effects of blowing the nose frequently. The oil also helps to strengthen the tissue of the nasal passages, making it more resilient and better able to deal with inevitable exposure to irritants. You may find that applying oil will solicit the impulse to blow your nose. Don’t worry if you must as it may require several oil applications to resolve this feeling and to gain relief from the sinus irritation.

Movement can also be extremely helpful in relieving allegy symptoms and clearing the sinus passages. Almost any intelligent movement will help, but a specific movement that seems to work well is to do a series of standing forward bends.

With the feet paralell and about 1 foot apart, bend forward with the knees straight down to a height that does not require a lot of bend from your spine. Use a chair or a yoga block as a support to put your hands on, but avoid leaning into the hands and keep the weight of the body mostly in your heel bones. Hold the forward bend for 5-10 seconds, breathing through your nose as much as possible. Then come up, keeping the knees straight and the weight in the heels until you are fully upright. Stand upright for another 5-10 seconds and then repeat the forward bend. Continue to alternate between the forward bend and standing upright until you start of feel your sinuses clear or you reach your fatigue point, whichever comes first.

Finally, altering our breathing pattern can be very helpful in relieving allergy symptoms. This is especially the case for anyone who tends to breathe through their mouth or must do so because of sinus congestion. When we breathe through our mouth we over oxygenate our blood, throwing off the delicate balance of oxygen and carbon dioxide necessary to make oxygen available to our cells. When our cells don’t get the oxygen they need, even for a short time, they struggle to metabolize well and this makes it difficult for our cells and the tissues they make up to neutralize pathogens. The following breathing exercise can be quite effective.

Sit quietly for a minute or so and allow your breath to be normal and relaxed. Set a timer for 5 minutes. Start to take smaller, sip like inhalations, followed by normal exhalations (meaning don’t attempt to alter your exhalation). Continue this breathing pattern for as long as is reasonably comfortable. If you start to feel short of breath, take a few normal inhalations until your breath recovers, then begin taking smaller inhales again. Continue this process, staying as relaxed as possible for the full 5 minutes.

With many of the over the counter medications available for allergy relief being so effective it’s tempting to rely on these and forgo other solutions. Ayurvedic medicine provides some easy to do and helpful means of symptom relief, as well as a fairly straightforward view of what causes allergies and how to address this cause at its root. The suggestions I’ve given above are a boon to anyone suffering with seasonal allergies and who is interested in relief that goes beyond symptoms. These suggestions may also provide insights into how other aspects of our health may be contributing to our allergies.

 

 

The Best Breathing for Reducing Pain and Stress

in , , ,

When working with our clients one of the first things we check is their breathing pattern. This is because the way a person breathes can have a big impact on their health, including the health and function of the musculo-skeletal system. Much of the impact of breathing on our health has to do with the role of our diaphragm.

The Diaphragm during Respiration

There are many ways to breathe but the most effective, efficient and relaxing way to breathe involves using our diaphragm. The diaphragm is a dome-shaped muscle that spans the lower border of our rib cage. On inhalation, as the diaphragm contracts, it flattens and moves downward. This downward motion creates a vacum in the chest, helping to pull air into the lungs. When the diaphragm relaxes it moves upward, back into its dome shape, and this upward motion helps us to exhale.

Intra-abdominal Pressure and the Stabilizing Role of the Diaphragm

The downward motion of the diaphragm also creates pressure in the abdomen. This pressure is called “intra-abdominal pressure” and is important for facilitating a stabilizing response in the muscles of our abdomen, low back and pelvis. This highlights the dual role of the diaphragm. Under optimal circumstances it acts as a facilitator of both respiration and muscle-skeletal stabilization.

Often people are taught diaphragmatic breathing by lying down and breathing into the belly, inflating it toward the ceiling. Although this may be a good way to get started, it is an approach which focuses only on the respiratory role of the diaphragm and fails to address its crucial role in stabilizing the trunk and pelvis.

Experiencing Diaphragmatic Breathing and Intra-abdominal Pressure

For the diaphragm to perform optimally in both of it’s roles it is essential that its downward motion be symetrical and that the pressure it creates in the abdomen be distributed evenly. To experience this even distribution of intra-abdominal pressure for yourself, place your hands around the abdomen just below the lower ribs, making contact with the front, sides and back of your body. Your diaphragm sits just above where your hands are touching. Now inhale and feel how the pressure created in your abdomen is pushing gently into your hands.

True diaphragmatic breathing creates intra-abdominal pressure that expands outward into the full circumference of the abdomen. When you breathe in with your hands wrapped around your abdomen, check and see if you feel the pressure moving in all directions. If you feel most or all of the pressure pushing into your belly, then on subsequent breaths try to gently, but consciously, redistribute the pressure into every place your hands are touching, especially into the sides of your waist and into the back.

Another technique for improving diaphragmatic breathing and intra-abdominal pressure involves tying a theraband or a stretchy cloth around your lower ribs and feeling your inhale touch the whole circumference of the lower ribcage.  Here you can feel the intercostal muscles between your ribs move. The intercostals assist the diaphragm in playing both its roles and are an important source of load and mobilization of the rib cage, helping to keep these bones healthy and mobile.

Intra-abdominal Pressure and the Pelvic Floor

As I mentioned earlier, when we are truly breathing diaphragmatically the downward motion of the diaphragm will be symetrical and create an even distribution of pressure in the abdominal cavity. But it doesn’t stop there! In fact one important benefit of diaphragmatic breathing is its affect on the pelvic floor. This is because true diaphragmatic breathing and optimal intra-abdominal pressure will move directly downward toward the pelvic floor, loading the pelvic floor muscles and soliciting a response from those muscles that maintains their strength and responsiveness.

To sense the intra-abdominal pressure in your pelvis,  place your hands on the front of your belly below your umbilicus (belly button) and above your pubic bone and take a breath. You should feel a gentle pressure increase here. You may also begin to sense a gentle pressure in the floor of your pelvis.

Other Benefits of Diaphragmatic Breathing

Another reason the direction our diaphragm moves is so important is that it helps pull air into the lowest lobes of your lungs. Since the lungs are narrow at the top and wider at the bottom, blood flow into the lower lobes is greater than into the upper lobes and therefore breathing diaphragmatically will allow for more oxygen transfer into the blood. With a big chest breath we are actually taking in less oxygen than if we simply take a small but healthy diaphragmatic breath!

Diaphragmatic breathing also has benefits to our nervous system. The para-sympathic nervous system (rest and digest) is activated by relaxed, diaphragmatic breathing while the sympathetic (fight or flight) is activated by chest breathing. Again, for healthy breathing that big chest breath is not always what we want. It is actually preparing our body to ramp up, promoting a stress response rather than alleviating it.

Diaphragmatic breathing can also help alleviate back pain and reduce back tension. When breathing diaphragmatically, the intra-abdominal pressure solicits a response in the abdominal and lower trunk muscles that gently unloads the spinal joints and strengthens the abodminal muscles. These muscles get a gentle massage and workout just by breathing correctly!

Breathing through Your Nose is Essential

Finally, to get the most out of diaphragmatic breathing it is essential to breathe in and out of your nose. Mouth breathing is shallow and will promote lifting the chest up in lieu of the diaphragm moving down. Since ALL of the benefits of diaphragmatic breathing hinge on the symetrical downward movement of the diaphragm and the even distribution of intra-abdominal pressure then breathing through the nose is key in reaping these benefits.

Exercising For Health vs. Fitness

in , ,

I think we can all agree that exercise is a good thing, regardless of how motivated we may or may not be to do it. The questions that remains are whether a particular activity can be called “exercise” and whether one type of exercise is better than another. Sports are a great example of this. I love basketball! I don’t play it anymore but I find it really fun to watch and can appreciate that it’s even more fun to play. Is playing basketball exercise? If so, is it good exercise? This depends on what you mean by good exercise.

What is good exercise?

If a client of mine asks me my opinion about an activity they engage in from the standpoint of it being good or bad, I always ask first what is the primary reason they are doing that activity. Recently I had been working with a client who had been running for exercise in the past but had stopped because it was impacting his health in negative ways. After a few sessions he was feeling much better and he asked me if I thought he should go back to running. I asked him “do you like running?” His answer was an unqualified “No”. I then told him that I would not recommend he start running again.

Now I know an awful lot of people LOVE to run and to anyone who loves to run I would say this – if you love it and it’s not impacting your health in ways that are interferring with other important activities or responsibilities in your life then absolutely you should run. But if you don’t love it, then I really don’t recommend it as I belive it puts too much stress on the body in a variety of ways to really be healthful. Frankly I don’t think running is “good exercise.” And I would say the same thing about a lot of what serves as exercise in the fitness realm these days.

Why are we exercising?

This brings up an important point. We don’t always exercise for health reasons. Or, we place our psychological health ahead of our physical health, if those can really be separated. By this I mean many people enjoy and hugely benefit from the satisfaction that an intense, demanding workout brings. It’s reinforcing to work hard and feel like we’ve accomplished something physically challenging. And there’s absolutely nothing wrong with doing this.

But if I am running a lot and I’m having joint pain that is affecting my ability to move in other ways and this pain is getting worse and I am experiencing some level of debilitation as a result or I see debilitation looming on the horizon then I need to reasses whether running is really the form of exercise I ought to be doing and start considering other options.

What is fitness?

Exercise done for reasons OTHER than promoting health I would generally categorize as a fitness activity. Fitness activities are a type of training used to become proficient at or “fit for” that same activity or a related one. If I want to be good at basketball then I should practice things that will improve my game and make me more “fit” as a basketball player. Will those same activities make me a healthy person? In some ways maybe, but in many ways clearly not. Just look at the athetes who play basketball professionally for a long time. They are frequently hobbled. Kobe Bryant and his knees come to mind.

Movement and Exercise

On the most fundamental level human beings thrive on movement. The better we move and the greater variety of movements we’re able to execute the greater potential we have for health and longevity. Movement is not sexy, but it is essential. Elderly people who fall down and break their hip often decline very quickly, even if they were functioning pretty well beforehand. Once our movement becomes very limited then our health immediately suffers. If you’ve ever suffered a serious injury that severly curtails your activity you know exactly what I’m talking about.

Exercising for health

Exercise that is done for health reasons is also a type of fitness activity in that it makes us more “fit” for fullfilling our human needs. On the most basic level our human needs consist of eating, sleeping and procreation with most of the fitness requirements related to eating in the form of food gathering and preparation. To eat a varied diet, our hunter gatherer ancestors needed to move and move in a lot of different ways from squatting to digging to climbing to chopping to grinding.

The what and why of exercise

Now that we have outsourced so much of the movement in our diet we don’t even think about all of the work that went into bringing our farro, arugula, beet and goat cheese salad to the table. The substiute for all of the digging, fertilizing, harvesting, picking, feeding, milking, processing, packaging and shipping that went into our salad has become exercise. Therefore if we wish to replace these outsourced movements with exercise, that exercise should have a significant variety of postures and movements. A single activity with a repetitive and limited movement profile like running won’t provide the variety of movements that will make us “fit” for the variety of human activities that keep us healthy. Again if you love running (or some other limited movement profile fitness activity) do it, but see if for what it is and what it isn’t. It IS going to make you very fit for running but it ISN’T going to make you fit for meeting your human needs.

Haven’t we adapted to modern life?

I suppose there’s an argument to be made that as our lifestyles have changed our needs have changed with them. Haven’t we as human beings adapted to the more sedentary lifestyle we now lead? Certainly we have. After all our bodies and our minds are extremely efficient in adapting to change. I can train myself to sit at a desk for 8 hours a day and have lunch delivered to my office. But is that what I want to be fit for? Sitting and eating takeout? Are those adaptations manifesting health?

Our bodies and minds adapt to the input they are given and therefore it’s the things we do most often that have the biggest impact on our health and function. It is this fact that we need to consider when making choices about exercise because ultimately it won’t be the 1 hour per day of exercise that has the greatest impact on our health but rather what we’re doing for the other 23 hours. How does the activity we’re spending an hour doing affect us during the rest of our day? Is our 1 hour of exercise making us more fit for enjoying a high quality of life? Or are we simply making ourselves fit for a single activity that may or may not be good for us in the long run?

Tips for Promoting Cardiovascular Health, Part 3

in

As we’ve seen in the earlier posts on CV health, much of what we can do to promote CV health goes beyond diet, exercise and medications.  The way we hold and move our bodies has a dramatic impact on whether our CV system will experience turbulent flow, wall wounding and the subsequent plaque formation that leads to CV disease.  Correcting the mis-alignments that distort our blood vessel geometry goes a long way toward minimizing turbulent flow, particularly in the abdominal aorta and the carotid arteries.  But what else can we do to reduce turbulent flow and the resulting damage to our CV system?

What else reduces turbulent flow?

Besides our blood vessel geometry, there are several other causes of turbulent flow that we have it in our power to correct or minimize.  One is sudden changes to the size of our blood vessels.  This refers to a sudden dilation of a blood vessel which results in blood squirting through the vessel in much the same way that water in a kinked hose squirts through rapidly when unkinked.  The result of this sudden rush of blood through the vessel is turbulent flow.

What causes sudden a change to blood vessel size?

There are several factors which contribute to sudden change in blood vessel size.  One major one is biological stress.  Biological stress results when we ignore our biological needs to the point that it impacts our health.  This is a distinct category of stress from what most of us are referring to when we say “I’m stressed,” although they are often related.

When the word “stress” is used in common language, usually we are referring to the pressures of modern life.  Things like work, traffic, relationships and taking too many things on at once can produce a feeling we call “stressed”.  Certainly this type of stress can be problematic for CV health as it tends to increase blood pressure, but biological stress is different.

Understanding Biological Stress

If I am working and perhaps on a deadline and I decide to skip a meal to get more work done even though I am hungry, then I am creating biological stress. If I decide to work very late into the night and I fail to get enough sleep so that I return to work tired the next day, then I am creating biological stress.  If I need to use the bathroom but I ignore the urge because it’s inconvenient for some reason, then I am creating biological stress.

These types of stressors, while they may very well be related to the “stress” in my life are different in that they trigger the release of hormones in my body that cause my blood vessels to dilate suddenly.  This sudden change in the blood vessel size causes turbulent flow.  This is similar to the affect that cigarette smoking would have on my CV system if I were a smoker.

What can I do about Biological Stress?

It may seem obvious, but reducing biological stress is as easy as the not so easy solution of eating when I’m hungry, sleeping when I’m tired and using the bathroom when the urge comes. If I’ve been supresssing biological urges for a long time, it may be necessary for me to reaccustom myself to the feeling of these urges to know when an appropriate response is called for.  Typically I’ll need to make responding to these urges more of a priority, relative to the activities which are impeding my response.  The demands on my time and energy are important, but are they so important that I must neglect my most basic human needs?

What else can I do to reduce turbulent flow?

Besides improving blood vessel geometry and minimizing biological stress we can also reduce turbulent flow by keeping our blood sugar at healthy levels. This is because sugar in the blood causes it to be thicker and stickier and this alters the way it moves through blood vessels.  This alteration in blood viscosity in turn leads to turbulent flow, wall wounding and plaque formation.

Decreasing blood sugar goes beyond diet.

How then do I keep blood sugar at healthy levels?  Reducing simple sugars in the diet of course helps and is important, but we should also consider something else when addressing blood sugar – how we are moving. Movement that requires more muscles to work will also increase cellular metabolism and decrease blood sugar because the cells of active muscles require more food to do their work.  Obviously we shouldn’t be eating a lot of sugar, but perhaps it’s even more important that we move more throughout our day to increase muslce use and cellular metabolism.

In conclusion, let me suggest that movement in alignment and with regular frequency is not optional for our health, cardiovascular or otherwise.  Natural movement, like food, sleep and regular elimination is a biological imperative.

 

Tips for Promoting Cardiovascular Health, Part 2

in

In my last post I discussed the function of the C.V. system and it’s component parts and I highlighted the imperative of movement to our cardiovascular health.  In this post I’d like to discuss what behaviors and circumstances damage our C.V. system and might lead to C.V. disease.

What Damages the C.V. System?

The main contributor to diminished C.V. health and overall health in general is plaque formation in our blood vessels.  Plaques are formed from cholesterol and when enough of them form inside a blood vessel they harden the vessel walls.  Plaques can also accumulate to the point of blocking a major artery which is clearly a very serious condition.  Thus for obvious reasons medicine has aggressively sought to reduce the buildup of cholesterol plaques by recommending diets low in cholesterol and prescribing cholesterol reducing drugs to patients.  But is too much cholesterol the whole story?

Why Does Plaque Form?

While the majority of us know about cholesterol and it’s capacity build up and harden or even block our blood vessels, why this happens is typically less understood.  Cholesterol plaques forming in our blood vessels are a natural result of tiny injuries to the walls of our blood vessels called wall wounding.  When such a wall wound manifests our bodies use plaque to patch the wound in the same way we form scabs when we suffer wounds to our skin.  The plaque protects the site of injury so that it has a chance to heal.  Therefore plaque and cholesterol are not really the primary cause of C.V. disease.  The primary cause is wall wounding.

What Causes Wall Wounding?

Under normal circumstances our blood flows smoothly through our blood vessels.  However, when blood flow is not optimal our blood cells can hit the inner walls of our blood vessels strongly enough to leave little nicks in the vessel walls.  This pathological movement of blood through the vessels causing wall wounding is called turbulent flow.  If we can reduce turbulent flow in our blood vessels then we can also reduce wall wounding and plaque formation.

What Causes Turbulent Flow?

Turbulent flow has a variety of causes, all of which are preventable.  Of these causes the one I’d like to discuss here is blood vessel geometry.  In the same way that our muscles, bones and joints have an ideal relative alignment, that is, one that optimizes functionality and minimizes wear and tear, our blood vessels also have an ideal alignment or geometry. The ideal alignment of our blood vessels is one that allows our blood to flow freely and without turbulent flow.  Misalignment of the musculoskeletal system typically result in misalignment of our blood vessels.  Often this places a bend in the vessel where, were the body better aligned, there would be no such bend.

A great example of this is the way a common misalignment of the cervical spine puts a bend in the carotid arteries.  Since these arteries are the main suppliers of oxygen to the front part of the brain any wall wounding and plaque formation in these vessels which might impede or even block flow is a clearly not good.  But we can reduce or even eliminate damage to these arteries by improving the alignment of our head and neck.

Figure 1

Figure 1

In the photo below (see figure 1) you can see a very common misalignment of the head and neck referred to as “chin forward posture.”  Chin forward posture misaligns our cervical spine in a way that excessively loads the discs, contributes to muscle tension, muscle weakness and unnecessarily stresses the spinal cord.  It also misaligns the carotid arteries contributing to turbulent flow, wall wounding and plaque formation in these arteries.

Comparing this photo to the one below it (see figure 2) you can see the head and neck brought back into a healthier alignment. This not only reduces stress on the neck muscles, cervical vertebra and spinal cord but will also be a better alignment for blood flow to the brain and will reduce turbulent flow and wall wounding.   This is clearly a good thing.

While there are other causes of turbulent flow, blood vessel geometry is an important one and one that is often overlooked as a contributing factor in C.V. disease.  The next post will look at the other causes of turbulent flow and discuss other ways we can avoid it and avoid this important contributing factor to C.V. disease.
