The "side-effect" it will have is a better health. Speaking from experience. When my husband and I separated, my health suffered, not in a big way, but in a series of small discomforts, to which I wasn't used to before. By taking yoga, these discomforts vanished. I felt, as if yoga brought balance and harmony to my mental state and my physical body. Just keep doing it.

Yep, I agree with Vlasta. It is centered around mind/body- it will help you become more flexible and strong, it will provide an avenue for exercise even though Yoga isnt for weight loss it will help you feel better and stronger and it will tone a bit. Its very good for stress relief as many yogiis teach breathings techniques and stress relief techniques. Yoga itself is a practice that is thousands of years old and specifically centered around creating a calm, tranquil atmosphere to "center" your mind and body.

The "side-effects" are all positive, especially if you work within your physical limits. Yoga is a wonderful form of exercises that not only changes your body, but improves your peace of mind, strengthens your spirit and decreases stress. There is no better way to strengthen your body, mind and spirit!

As long as you don't overdo it, yoga is a great way to improve mind-body health. :)
