More than a stretch: Yoga’s benefits may extend to the heart

Yoga is good for the muscles and the mind. New research suggests that it may also be good for the heart. A review of yoga and cardiovascular disease published in the European Journal of Preventive Cardiology indicates that yoga may help lower heart disease risk as much as conventional exercise, such as brisk walking. It can help people lose weight, lower blood pressure and cholesterol, and ease stress. Each of those changes works to prevent heart disease, and can help people who already have cardiovascular problems.

Acupuncture for knee arthritis fails one test but may still be worth a try

A report published this week in the Journal of the American Medical Association offers weak-to-no proof that acupuncture helps ease the pain of knee arthritis. In a group of older men and women with arthritis-related knee pain, Australian researchers compared traditional needle acupuncture against laser acupuncture, sham laser acupuncture, and no treatment. People who had needle or laser acupuncture reported slightly less pain and slightly better physical function compared with the group that had no treatment at all. Sham acupuncture worked as well as real acupuncture, suggesting the placebo effect may be at work.
