Yoga

In the cobra pose, for example, you ask yourself, What would it feel like to be a cobra. You lie on your stomach with your forehead to the floor. As you inhale, you slowly roll your head back, supporting yourself with your hands. You hold that pose, then come down slowly, trying to move as a snake would move.

All yoga exercises promote strength and calmness. Each move's effects on a muscle, a gland or a nerve center are carefully thought out.

You can choose certain exercises to rid yourself of particular pains, such as back pain from back-packing or leg pain from jogging. Yoga can help condition you for skiing or help you control feelings of depression or fear.

Any good book on yoga will describe various asanas and tell how each works. You may even have done yoga exercises already. Ever done a handstand, or the wheel. Many exercise programs borrow from yoga.

Hatha is the most popular type of yoga in the Western world. It is a slow-paced discipline that emphasizes controlled breathing and assuming various physical poses. It is said to aid the nervous system, the glands and the vital organs.

Kundalini, which was introduced to this country in 1969 by Yogi Bhajan, is more active, combining various modes of breathing, movement and meditation. It is based on the idea that body energy that is coiled below the base of the spine can be tapped so that it travels upward through different energy centers or chakras until it reaches the head. At this point one arrives at one's highest potential.

Classically, there are 84 basic yoga positions, or asanas, which are coordinated with special breathing techniques. The asanas range from simple bends and twists to pretzel-like contortions reserved for the most advanced practitioners. The various poses elongate the muscles and build flexibility. Along with the proper breathing, they help rid the body of tension. Static holds isolate and strengthen particular muscles.

Asanas have been evolved over the centuries so as to exercise every muscle, nerve and gland in the body. They secure a fine physique, which is strong and elastic without being muscle-bound, and they keep the body free from disease. They reduce fatigue and soothe the nerves. But their real importance lies in the way they train and discipline the mind.

Growing interest in the mind-body connection is fueling a major comeback of the ancient practice, boosted by research suggesting it can reduce stress and blood pressure, improve work performance, even slow effects of aging.Several techniques are now being taught in mainstream hospitals and businesses; books about them are brisk sellers and discussion groups have sprung up on the Internet.

Even the Army is interested - it has asked the National Academy of Sciences to study meditation and other new age techniques that might enhance soldiers' performance. Details differ, but a common theme is relaxing the body while keeping the mind alert and focused - on an object, sound, breath or body movement. If the mind wanders - and it always does - you gently bring it back and start again

Stress-related problems account for 60percent to 90percent of U.S. doctor visits, and mind-body approaches often are more effective, and cost-effective, than drugs or surgery. For example, 34percent of infertile patients get pregnant within six months, 70percent of insomniacs become regular sleepers and doctor visits for pain are reduced 36percent.
