Yoga Means Less Stress, More Calm
Even beginners tend to feel less stressed and more relaxed after their first class. Some yoga styles use specific meditation techniques to quiet the constant "mind chatter" that often underlies stress. Other yoga styles depend on deep breathing techniques to focus the mind on the breath. When this happens, the mind calms.
Among yoga's anti-stress benefits are a host of biochemical responses. For example, there is a decrease in catecholamines, the hormones produced by the adrenal glands in response to stress. Lowering levels of hormone neurotransmitters -- dopamine, norepinephrine, and epinephrine -- creates a feeling of calm. Some research points to a boost in the hormone oxytocin. This is the so-called "trust" and "bonding" hormone that's associated with feeling relaxed and connected to others.
Yoga, Concentration, and Mood
Harder to pin down and research scientifically, concentration and the ability to focus mentally are common benefits you'll hear yoga students talk about. The same is true with mood. Nearly every yoga student will tell you they feel happier and more contented after class. Recently, researchers have begun exploring the effects of yoga on depression, a benefit that may result from yoga's boosting oxygen levels to the brain. Yoga is even being studied as an adjunct therapy to relieve symptoms of obsessive-compulsive disorder.
Yoga's Benefits the Heart
Perhaps one of the most studied areas of the health benefits of yoga is its effect onheart disease. Yoga has long been known to lower blood pressure and slow the heart rate. A slower heart rate can benefit people with high blood pressure, heart disease, andstroke. Yoga was a key component to the heart disease program designed by Dean Ornish, MD. This was the first program to partly reverse heart disease through lifestyle and diet rather than surgery. On a biochemical level, studies point to a possible anti-oxidant effect of yoga. And yoga has been associated with decreasedcholesteroland triglyceride levels as well as a boost in immune system function.
