Count on Yoga: 38 Ways Yoga Keeps You Fit

Are you looking for reasons to start practicing? Here are ways yoga improves your health—reasons enough to roll out the mat and get started.

If you're a passionate yoga practitioner, you've probably noticed the ways yoga works—maybe you're sleeping better or getting fewer colds or just feeling more relaxed and at ease. But if you've ever tried telling a newbie how it works, you might find that explanations like "It increases the flow of prana" or "It brings energy up your spine" fall on deaf or skeptical ears.

As it happens, Western science is starting to provide some concrete clues as to how yoga works to improve health, heal aches and pains, and keep sickness at bay. Once you understand them, you'll have even more motivation to step onto your mat, and you probably won't feel so tongue-tied the next time someone wants Western proof.

I myself have experienced yoga's healing power in a very real way. Weeks before a trip to India in 2002 to investigate yoga therapy, I developed numbness and tingling in my right hand. After first considering scary things like a brain tumor and multiple sclerosis, I figured out that the cause of the symptoms was thoracic outlet syndrome, a nerve blockage in my neck and chest.

Despite the uncomfortable symptoms, I realized how useful my condition could be during my trip. While visiting various yoga therapy centers, I would submit myself for evaluation and treatment by the various experts I'd arranged to observe. I could try their suggestions and see what worked for me. While this wasn't exactly a controlled scientific experiment, I knew that such hands-on learning could teach me things I might not otherwise understand.

My experiment proved illuminating. At the Vivekananda ashram just outside of Bangalore, S. Nagarathna, M.D., recommended breathing exercises in which I imagined bringing prana (vital energy) into my right upper chest. Other therapy included asana, pranayama, meditation, chanting, lectures on philosophy, and various kriya (internal cleansing practices). At the Krishnamacharya Yoga Mandiram in Chennai and from A.G. Mohan and his wife, Indra, who practice just outside of Chennai, I was told to stop practicing Headstand and Shoulderstand in favor of gentle asana coordinated with the breath. In Pune, S.V. Karandikar, a medical doctor, recommended practices with ropes and belts to put traction on my spine and exercises that taught me to use my shoulder blades to open my upper back.

Thanks to the techniques I learned in India, advice from teachers in the United States, and my own exploration, my chest is more flexible than it was, my posture has improved, and for more than a year, I've been free of symptoms.

My experience inspired me to pore over the scientific studies I'd collected in India as well as the West to identify and explain how yoga can both prevent disease and help you recover from it. Here is what I found.

Strength Test
2 Strong muscles do more than look good. They also protect us from conditions like arthritis and back pain, and help prevent falls in elderly people. And when you build strength through yoga, you balance it with flexibility. If you just went to the gym and lifted weights, you might build strength at the expense of flexibility.
