Why yoga can help back pain:
Yoga teaches you healthy, natural ways to move your spine and whole body. You'll be less likely to aggravate a back injury through mindless movement in everyday life.
Yoga reduces stress. Back pain is strongly related to stress. Stress increases muscle tension and joint inflammation, and makes the pain receptors in your body and brain reactive to pain. Yoga teaches you how to relax unnecessary tension, how to breathe in a way that shuts down stress, and how to take time to yourself for rest and recovery from the craziness of life.
Yoga helps the body and brain produce the natural chemicals that suppress pain and produce feelings of pleasure and joy. It puts your mind and your body in a better mood. (More)
