Yoga for cancer patients provides benefits of sleep, vitality.

By Tom Randall

NEW YORKAuTouch toes. Downward dog. Breathe. ItAAEs a yoga routine that cancer doctors have prescribed for years without evidence it would do much good.

Now the biggest ever scientific study of yoga finds their instincts were right.

While yoga doesnAAEt cure the disease, its stretching and breathing exercises did improve sleep, reduce dependence on sedatives and help cancer patients resume the routine activities of everyday life, according to a 410-participant study

being highlighted at the American Society of Clinical OncologyAAEs annual meeting in Chicago next month.

Health insurers and government programs donAAEt pay for yoga even as mounting evidence from dozens of smaller studies show benefits for treating chronic disease. The research and more than $5 million in additional tests funded this year by the National Institutes of Health may convince skeptical doctors and provide scientific evidence to allow coverage.

AoClinicians should now feel pretty comfortable prescribing gentle Hatha yoga or restorative yoga for their patients,Ao said Karen Mustian, lead author of the study and assistant professor in the department of radiation oncology and preventive medicine at the University of Rochester Medical Center. AoThe data from this study is one of the first steps in the direction toward insurance coverage, but weAAEre not there yet.Ao

David Goldberg, 30, a computer programmer, learned earlier this month that he has leukemia. The cancer cut short his five-mile runs and pick-up basketball games even before his diagnosis. Goldberg hadnAAEt considered yoga until checking into hospital a few weeks ago and learning of his disease.

AoI was certainly a little skeptical, but so far itAAEs been very helpful in relaxing me, getting me in a good state of mind,Ao Goldberg said. His instructor wears a mask to protect Goldberg, whose immune system has been weakened by five rounds of chemotherapy.

AoIAAEm hooked up to a machine, so I canAAEt totally forget that I have this. For me, itAAEs just an amazing experience to feel where my body is and what IAAEm experiencing,Ao he said.

The yoga study released Thursday by the cancer group is one of more than 4,500 reports showcased at this yearAAEs meeting of 30,000 oncologists. Doctors have been especially interested in yogaAAEs muscle-toning stretches and meditative breathing, which practitioners say clears the mental fog of chemotherapy and the chronic fatigue that plagues some survivors for years.

In the Rochester study, about 8 out of 10 cancer survivors reported significant sleep impairment that affected their lives before the study. Half of the patients were assigned to yoga classes twice a week for one month. By the end of the trial, 31% of yoga patients no longer had the sleep disruptions, twice the recovery rate of patients who didnAAEt take classes.

Yoga practitioners also reported a 42% reduction in fatigue, compared with a 12% reduction for the control group. Yoga users decreased the use of sleep medication by 21%, while the control group actually increased reliance on sleeping drugs by 5%.

Scientists still donAAEt know exactly what makes yoga work, said Lorenzo Cohen, professor of behavioral science and cancer prevention at the University of Texas MD Anderson Cancer Center in Houston. Cohen and his research group were awarded a $4.5 million US grant this year for the biggest yoga and meditation study. His research will compare yoga to meditation and to stretching and will analyze economic benefits from increased productivity at work.

AoOnce we can show an economic impact, youAAEll start to see changes,Ao Cohen said. AoCompanies want to provide services that keep their employees healthy and productive.

AoThe concept that the brain can change if you put it into different states is a whole new wonderful science thatAAEs emerging,Ao Cohen said.

Yoga began in India as a combination of physical and mental exercises. Historians have traced its roots back thousands of years to references in Buddhist and Hindu texts. In Western practices, muscle-stretching poses are accompanied by meditative breathing exercises. About 15.8 million Americans practiced yoga in 2008, according to a study commissioned by Yoga Journal.

Its health benefits have been explored in scores of smaller studies looking at everything from weight loss to depression. Previous studies were too small to be considered definitive, and they are difficult to compare because most of them use differing definitions for just what AoyogaAo is.

For Goldberg, yoga is a series of slow, gentle stretches, beginning with his feet and ending in his shoulders. The reclining poses are followed by guided breathing instructions that encourage him to let go of the sounds of the hospital and to focus on his thoughts and the sensations of his body.

After his session, Goldberg told his instructor that a headache that had been bothering him during a visit with his family had disappeared and his outlook on the world was little bit brighter than before. His doctors said his positive attitude is a strong medicine and his prognosis for recovery is good.
