New studies offer evidence of the mind and body benefits of yoga

The idea that yoga is beneficial is not new. But new studies continue to advance our understanding of the health benefits attained through yoga practice. Three studies reported in the April 2014 issue of the Journal of Alternative and Complementary Medicine show that yoga can improve balance and reduce fear of falling, helps to reduce and regulate blood pressure and can improve important aspects of cardiovascular health.

As we age, it is common to experience a loss of balance and an increased risk of injury due to falling. Yoga, with its great emphasis on enhancing overall balance, demonstrates the capacity to reduce age-related imbalance and the tendency for fall-related injuries. Researchers at Johns Hopkins University examined 152 studies on yoga, identifying 15 that assessed balance-related issues. Among these, 11 studies showed that yoga practice can enhance balance, reduce the incidence of balance-related falls and reduce fear of falling – a common issue among seniors.

The balance study was not based on one style of yoga or on one particular practice, but on several styles, and on a number of methods aimed at improving balance, especially one-legged standing poses.

Yoga is low impact and can be adapted to meet the abilities of most people. Yoga practice shows no negative interactions with medications and improves body awareness, a factor in loss of balance. The bottom line of this study was that yoga can improve balance and reduce falls that lead to injury. For seniors, this is a significant gain.

The second yoga study, conducted at the University of South Carolina College of Medicine, examined the effects of Hatha yoga on blood pressure among a group of young people. Hatha yoga is the most commonly practiced of yoga styles. The study involved a group of 28 seventh-graders. Half of the group participated in school-based yoga practice for three months, while the other half attended a music or art class. Among these students, some were pre-hypertensive, meaning they exhibited standard clinical signs of early-stage high blood pressure.

Overall, the students who practiced yoga had lower resting blood pressure and reduced a-amylase activity, a determining factor in high blood pressure, as determined by a variety of tests. Researchers concluded that Hatha yoga helps to decrease resting blood pressure and regulate important nerve and hormonal factors that can lead to blood pressure disorders. This finding is consistent with other assessments of blood pressure among those who practice yoga. Given that high blood pressure is a common problem that can lead to other health complications and increase mortality, this benefit is significant.

The third yoga study, conducted by researchers at Eastern Virginia Medical School, examined a group of Tibetan yogis who engage in an extreme yoga practice known as Tumo, or Tum-Mo, at very high altitude in the freezing Himalayan cold. This technique seems to enable the yogis to maintain normal body temperatures at very cold temperatures, apparently without harm.

Dum-Mo has been studied and filmed by American cardiologist Dr. Herbert Benson, who founded the Mind/Body Medical Institute at Massachusetts General Hospital in Boston. In Benson’s film, the yogis, clad only in loin cloths, sit on the freezing ground melting iced sheets wrapped around their bodies, while members of the film crew huddle in heavy down-filled mountaineering gear.

The Eastern Virginia Medical School study examined various cardiovascular factors of both non-yogis and yogis in sub-zero temperatures. As expected, the non-yogis were not capable of generating inner body heat, and had to be warmed to maintain a healthy body temperature. The Tum-Mo practitioners stayed warm without shivering. Analysis of heart rate, blood pressure and numerous other factors resulted in the conclusion that this mystifying practice somehow enables the Tum-Mo yogis to activate brown fat and generate heat, increasing overall blood flow greatly and decreasing peripheral vascular resistance.

The Tum-Mo study left many questions unanswered, but it showed yet again that yoga can exert profound changes in normal physiological activity – in this case, keeping Tum-Mo yogis warm at temperatures that would typically lead to death by hypothermia.

Deriving from India, China, Nepal and Southeast Asia, yoga practices of various types have gained popularity because they are adaptable to people of all ages and most levels of fitness, and impart significant benefits on both body and mind. These three recently reported studies support the salutary effects of yoga, and clearly show that practice can positively affect health in significant ways.

The art of yoga

It’s practiced by millions of Americans who credit it with bringing them better health, physical fitness, and serenity.

And then there are those who see it differently . . .

“How many of you would like to stay here for an hour and twist yourself into agonizing positions, ultimately wrapping your leg around your head?” Alec Baldwin asked a crowd. “How many of you would rather come with me to the movies and eat a pizza?”

Yes, that’s Alec Baldwin, the famously un-serene bad boy, who not long ago made headlines, again, when he got into an ugly scuffle with a photographer staking out his family.

When he spoke with Braver, just before that incident, he made no secret of the fact that his main interest in yoga isn’t anger management; it’s that his wife Hilaria is an instructor.

“When I came to her class the first time and watched her teach her class, all I wanted to do was, like, pour a glass of scotch and light a cigarette and just say, ‘This is never happening,'” Baldwin said.

But Baldwin was there — at least in body — when his wife taught an unusual class right in the Smithsonian’s Sackler Gallery in Washington, amid priceless works of art.

It’s the first major exhibit about yoga ever mounted in the U.S.
The Baldwins chaired the opening gala and helped sponsor the show, which Hilaria Baldwin says calls attention to the ancient origins of a practice that began in India some 2,500 years ago.

“By looking at the history, you see how deep the roots are,” Hilaria said, “and how important it has been through centuries. Now it kind of brings it full circle.”

Curator Debra Diamond, who began working on the exhibition in 2009, said the various depictions of yoga masters, known as yogis and yoginis, show that there was never one set tradition for yoga.

Some forms have links to Hinduism, Buddhism, and other religions.

One fragment of sculpture is from the 2nd century. Its gaunt figures, said Diamond represented renouncers — “those who gave up society, who began fasting and meditating in order to attain enlightenment and omniscience.”

But yoga practice was often completely secular. Kings and maharajas who believed that yoga could help them achieve supernatural powers, like levitation, commissioned a wealth of sculptures, paintings, and manuscripts.

So what does the word “yoga” mean?

“The Sanskrit root of yoga, which is yug, means to hold, to join, to unite,” said Diamond. “But the term yoga itself has probably more meanings than any other Sanskrit word. These range from the yolk, the harness of an ox, to the union between opposites.”

Americans, including Henry David Thoreau of Walden Pond fame, became interested in yoga as early as the mid-19th century.

But yoga later developed a somewhat less noble image.

Howard Thurston, a famous magician of the late 1800s, traveled the country claiming to have supernatural yoga-style powers, performing illusions like the suspended rope trick.

Diamond said many American first came to know of yogi through the conjuring of exotic stereotypes about India that were rather dubious. “Yogis became an embarrassment for Indians as well as for the rest of the world,” said Diamond.

But yoga’s image began to change after a 1938 film showing an athletic series of poses and postures to promote physical and mental fitness, developed by a 5-foot, 2-inch yogi named Krishnamacharya.

And today a lot of us are striking poses: A 2012 survey by Yoga Journal found that some 20 million adult Americans say they do yoga, up from 15.8 million in 2008.

But how real are the health benefits?

Dr. Lorenzo Cohen is the director of integrative medicine at M.D. Anderson Cancer Center in Houston, which offers yoga classes for patients and employees alike.

Dr. Cohen says, of the clinical trials that have been conducted, including some at M.D. Anderson, “We see that yoga can help improve fatigue, help improve sleep dysfunction in cancer survivors, as well as improve physical functioning.

“You’re engaging your mind, you’re engaging your breath, your lungs,” explained Dr. Cohen. “And in some sense, simplistically, a bio-behavioral change is happening within the body. By and large, you’re going to be decreasing stress hormones. Heart rate and blood pressure are going to reduce.”

And yoga is a booming business! According to one study, Americans spend nearly $6 billion a year on yoga classes and products.

Yoga studios are found in more and more towns. There was even a yoga garden at last April’s White House Easter Egg Roll.

And instructors like Hilaria Baldwin can teach even a yoga-phobic reporter (left) a move or two.

She persuaded her husband Alec to appear in her video for pregnant women. [They now have a four-month-old.] And Hillaria says yoga helped her become more relaxed:

“I just stopped taking things so seriously, which was really the key to being much happier,” she said.

“Has this rubbed off on you?” Braver asked Alec Baldwin.

“Only where the paparazzi aren’t involved,” he laughed.

In fact by any stretch of the imagination, yoga takes dedication and discipline, which a lot of us know we should have, but like Alec Baldwin, we may not be able to achieve, despite our best New Year’s resolutions.

“You know, I’m somebody who I think I have, like, half-wisdom,” he told Braver. “I know what I need to do. I just don’t do it! But I’m pretty certain what I need to do. I know exactly what I need to do.”

But never fear: Yoga has always been about the quest, as well as the accomplishment.
