We have some answers to these questions. There are many confusing and conflicting claims made about all alternative medicines. Yoga is included in this, but hopefully we can figure some of them out. People have claimed that yoga has had positive effects on them. Some believe that it helps them psychologically, some mentally, some, a combination of the two.
Most people relate yoga to the relief of stress, or minor pains.
Many studies were done to observe the effect yoga had on the relief of stress. One of these studies, done in 1994, was conducted on two groups of young women. One group was a control group and the other practiced yoga. All the volunteers read in a comfortable position for an extended period of time. Then, heart rate, blood pressure, certain hormones and psychological factors were measured and compared.
