Sitting is the New Smoking

by Nina
Woman Smoking by Kitagawa Utamaro
“Being out of shape could be more harmful to health and longevity than most people expect, according to a new, long-term study of middle-aged men. The study finds that poor physical fitness may be second only to smoking as a risk factor for premature death.” —Gretchen Reynolds, New York Times 

Have you heard the phrase “Sitting is the New Smoking” yet? Because recently I’ve been hearing it more and more often. And although lthough Ram didn’t use it in his recent post The Ill Effects of Prolonged Sitting he did say, “For people who engage in prolonged sitting activities, their risk of heart attack is about the same as smoking.” 

His post cited three different studies that showed the dangers of spending too many hours a day sitting. (That post got me to spend more time standing up at my sit-stand desk!) Then just a week later I read a NY Times article Being Unfit May Be Almost as Bad for You as Smoking about a new study on the longevity of men who were active versus those who were inactive (they measured aerobic capacity to indicate the subjects' general level of activity and fitness). What was special about this study was that it focused on a large group of about 1,000 healthy Swedish men of age 50, and followed them through the rest of their life spans (45 years!). (Many of these types of studies in the past have been done on older people for much shorter periods of time.)

The conclusion of the study Low aerobic capacity in middle-aged men associated with increased mortality rates during 45 years of follow-up was this:

“In this representative population sample of middle-aged men, low aerobic capacity was associated with increased mortality rates, independent of traditional risk factors, including smoking, blood pressure and serum cholesterol, during more than 40 years of follow-up.” 

And not only was poor fitness/low aerobic capacity second only to smoking as a risk factor for increased mortality, it was actually even unhealthier than high blood pressure or high cholesterol! Yes, the study found that the men who were rated as highly fit but who had high blood pressure or high cholesterol levels tended to live longer than men who were rated as “out-of-shape” but who healthy blood pressure and cholesterol levels. 

And although the study just focused on men (an ongoing problem in scientific studies), the NY Times reported that: 

But “there is no reason not to think” that the rest of us would also share any beneficial associations between fitness and longevity, said Per Ladenvall, a researcher at the Sahlgrenska Academy at the University of Gothenburg, who led the study. Past studies involving women have found such links, he said. 

Perhaps I am preaching to the choir by sharing this information (because you may already be practicing yoga on a regular basis and understand all its many benefits), but for those who are not yet physically active or who have family members or friends who are not active, the takeaway is clear: start being more physically active! The New York Times article concluded by quoting the Dr. Ladenvall saying that even small amounts of physical activity can have a positive effect.

“Encouragingly, if you now are concerned about the state of your particular aerobic capacity, you most likely can increase it just by getting up and moving. “Even small amounts of physical activity,” Dr. Ladenvall said, “may have positive effects on fitness.”

Yoga for Healthy Aging is Not Science Fiction: A Real-Life Mission Statement

by Nina 
Field of Mars by Marc Chagall*
“As more people are living longer and fewer are dying young from diseases caused by infections or insufficient food, exponentially more middle-aged and elderly people are suffering from chronic noninfectious diseases that used to be rare or unknown.” —Daniel Liberman

I’m just finishing up the Mars trilogy by Kim Stanley Robinson, a science fiction epic that takes place in the near future about the very first human settlers on Mars. The series spans a period of about 200 years, and several characters you meet at the beginning of the series are still alive at the end. When these characters are in their seventies and eighties, a longevity treatment is developed by Mars scientists that allows the original Mars settlers to continue to live active, healthy lives for an unknown amount of time. Although these characters do develop certain long-term memory problems (mostly about their middle lives), they continue to do productive scientific work, are energetic, physically fit and disease free, and even have active romantic and sex lives. Near the end of the series, a few of them die quite suddenly, not of any long, lingering diseases but very quickly of heart failure. And that seems to be the end that most, if not all, of them, will be facing.

Oh, if only old age was really like that, right? But this science fictional scenario actually exemplifies the very issues I wanted to talk about today. For when we talk about “healthy aging” on our blog, Sax, Nadia, Ann, Coyote, Michel, Maya and others in the Mars trilogy are ideal role models, not because of how long they live but for how healthy, physically active, and intellectually engaged they remain until the ends of their lives.

Lifespan. I guess this is rather obvious, but our “lifespan” is the period of time during which we are alive. But that lifespan could include any number of years spent in poor health. Sax, Nadia, Ann, et al in the Mars trilogy don’t have problems with ill health because in their science fictional world modern medicine can fix almost everything (although one man does die of leukemia). But here in the real world there are many medical conditions that just can’t be cured yet.

Morbidity. Right now, although our lifespans in first world countries have increased significantly due to better nutrition and modern medicine, as Daniel Liberman said in the quote above, middle-aged and elderly people in first world countries can suffer many years of ill health before they die. Lack of exercise, poor eating habits, and stressful lifestyles cause heart disease, strokes, diabetes, osteoporosis, and other chronic problems. This period of ill health during your lifespan is referred to as morbidity.

Now let’s do a little bit of very simple math:

Lifespan – morbidity = health span

Health Span. To put it in words, your “health span” is equal to your lifespan minus the amount of time you spend in ill health. This is the period in your life during which you are generally healthy and free from serious or chronic illness. For the people in the Mars trilogy, since they are very healthy until they suddenly die of heart failure, their health spans are very close to the length of their lifespans. But I’m sure in real life we all know people who live for years in a very debilitated state, perhaps in a nursing home, and I think we can all agree is not a future we would want for ourselves, if we can help it. (See Longevity vs. Morbidity for information about the epidemic of morbidity in the first world.)

So, to be clear, when we talk about yoga for “healthy aging,” we’re not talking about yoga for increasing your lifespan or your longevity. We’re talking instead about doing what you can to keep your health span as long as possible. And while you are makiing your health span as long as possible, we hope you'll also be making the period of time you spend in ill health near the end of your life as short as possible (this is called "compressed morbidity").

And, yes, we believe that yoga can help with this. Our mission here at YFHA is to explore all the ways that yoga can help foster your physical, mental, and emotional health during your lifespan (see Opening Your Yoga Toolbox). And because we’re not living in a science fictional universe, we must acknowledge that there will be times when ill health is unavoidable. But yoga has sometime valuable to offer you during those times as well, including both spiritual wisdom to guide you and tools for cultivating equanimity that will help see you through hard times.

This is all pretty basic stuff, but it’s worth saying because we want to set realistic expectations. We’ve certainly seen prominent new age health gurus out there claiming that you can “reverse aging,” choose your “biological age,” or “change your relationship with time” with yogic practices. But that really is science fiction. And here in the real world you deserve more than that.

Longevity vs. Morbidity (Ill Health)

by Nina 
Ice by Philip Amdal
“Stated succinctly, lower mortality is being replaced by higher morbidity (ill health).” —Daniel Lieberman, from The Story of the Human Body

For some time now I’ve been meaning to write about the difference between longevity (the number of years you live) and morbidity (the number of years you spend in ill health). I think it’s an important topic because morbidity, not longevity, is the issue we’re trying to address here on this blog. I’ve definitely had people challenge me about the longevity issue, saying for example, that if overweight people live just as long as thinner people, what’s the problem? Well, the answer is that the number of years you live is not the whole story. It’s also important to consider what your quality of life might be during your lifetime, especially your later years.

“As more people are living longer and fewer are dying young from diseases caused by infections or insufficient food, exponentially more middle-aged and elderly people are suffering from chronic noninfectious diseases that used to be rare or unknown.” —Daniel Lieberman

As I’m currently reading a book by Daniel Lieberman called The Story of the Human Body: Evolution, Health, and Disease that considers this very issue from the point of view of human evolution, I decided that now would be a good time to take on the topic of longevity vs. morbidity. (Hey, it’s always easier to write about something when I’ve got lots of handy quotes from an expert, in this case a professor of human evolutionary biology and the Edwin M. Lerner II Professor of Biological Sciences at Harvard.)

Here is how the book describes the current epidemic of ill health (morbidity) in the developed world:

“Cosseted by an embarrassment of riches, a majority of adults in developed countries, such as the United States and the United Kingdom are unfit and overweight, and the prevalence of childhood obesity is skyrocketing globally, presaging billions more unfit and obese people in the decades to come. Poor fitness and excess weight, in turn, are accompanied by heart disease, strokes, and various cancers, as well as a multitude of costly, chronic illness, such as type 2 diabetes and osteoporosis.” —Daniel Lieberman

Throughout the book, Lieberman talks about how human beings evolved to live a hunter-gatherer lifestyle, one that includes being very physically active (we evolved for endurance walking and running), eating lots of fruits and vegetables and other unprocessed foods (rather than quickly metabolized high-processed foods), and experiencing stress as an acute, episodic reaction rather than a chronic state. Our bodies are simply not built to handle being sedentary for years on end, a regular surfeit of calories, and/or a chronically stressful lifestyle.

And for the last couple of years, we’ve been on a mission to let you know the various ways that regular yoga practice can help with the morbidity that is becoming associated with aging in the developing world. Although they won’t turn you back into a hunter-gatherer, the yoga solutions we’ve been offering on this blog for the last couple of years will help you move back in the right direction. A regular asana practice is a great way to return to being physical active, one that helps you with strength, flexibility, balance and agility. Yoga’s stress management tools, including meditation, breath practices, and stress-reducing poses help reduce chronic stress associated with many serious illnesses, such as heart disease and high blood pressure. And for those with weight problems, yoga can be of some help in reducing the stress that can cause overeating and the especially dangerous abdominal fat, allowing you increase your will power, and teaching you to be more mindful in your eating habits.

“Just as this is not the best of all possible worlds, your body is not the best of all possible bodies. But it’s the only one you’ll ever have, and it’s worth enjoying, nurturing, and protecting. “ —Daniel Lieberman

Santosha, Smiling and Longevity

by Ram
by Norman Rockwell
In my previous article regarding santosha, Santosha: Happiness and Longevity, I mentioned that discontentment and unhappiness arise when we get caught up in the materialistic world. If we are happy with our lifestyle and what we currently have, it will help us in the journey to absolute truth and the highest realization.

Santosha Anuttamah Sukha Labhah


From an attitude of contentment/true happiness (santosha), mental comfort, joy, and satisfaction (anuttamah sukha) are obtained. —Yoga Sutras, translated by Swami Jnaneshvara.


This observation was supported by a scientific study that showed that people who are contented are not only healthier but they may also live longer (see Santosha: Happiness and Longevity).

There are several ways of expressing santosha or happiness. One visible way of showing that you are happy and contented is through a SMILE. Smiles can be warm, beautiful, welcoming, cute, innocent, charming or heart melting. A smile of any kind has the same positive effect: it brightens up the people surrounding the smiling person. Smile and notice that the people around smile with you. The world changes based on a person's perception and outlook, and having a smile on the face not only reveals the radiance of the person smiling but it also makes the individual a pleasurable person to be around.

A person with a smile not only mitigates the suffering around but also boosts up someone else's existence, even if it is for a fleeting moment. People tend to trust and cooperate more with individuals who sport a smile. Moreover, smiling is infectious; a smiling individual lightens up the room, change the moods of others, brings happiness along and attracts more people. Several scientific studies suggest that people who smile a lot are not only happy and contented, they are also more stable, happier in their marriages, have better cognitive skills and interpersonal skills. And now there’s an additional benefit that comes with a smile: it adds years to your life.

A study by researchers at Wayne State University concludes that a smile has an impact on aging and life expectancy. The wider you grin and the deeper you smile, the more likely you are to have a healthy aging and longer existence. For the study the researchers analyzed 230 pictures of major league baseball players who began their careers in professional baseball before 1950. The photos were enlarged and a rating of their smile intensity (big smile, partial smile, no smile) was noted. Researchers then ranked the players according to their smiles and laughter lines (length of the creases). The players smile ratings were compared with data from deaths that occurred from 2006 through 2009. The conclusions from the study:
  1. Players with big smiles (n=23) lived an average 79.9 years.
  2. Players with partial smiles (n=64) lived an average of 75 years. 
  3. Players with no smiles (n=63) lived an average of 72 years. 
The above results did not change when the researchers also corrected for other factors associated with longevity. Furthermore, the researchers also noted that the benefits did not extend to players who put out a false smile but only those who looked truly happy had the extra life expectancy.

One may wonder how the act of opening the lips wide and bringing on a smile triggers all of the above-mentioned benefits including longer lifespan? Studies have shown that a simple smile triggers several positive changes in the body. Smiling helps to boost the immune system, which provides resistance from many diseases. Smiling relieves stress, lowers blood pressure, triggers the release of endogenous pain killers and changes the mood attitude for the better, all of which help in graceful aging.

So how about bringing santosha in the form of a wide smile in your own lives as well? Smile as much as you can, even if you are not on camera!
