Yoga has helped me to deal with anxiety, stress, worry, and to improve my ability to relax. When I go to the yoga studio, the stress just disappears, I get exercise, but the meditation and relaxation, clearing my mind, have helped me so much in my life, especially the past 5 years, I have increased my yoga to 5-6 days per week. Everyone has their own outlets, I suppose, biking, running, some form of exercise.
I believe that the yoga asanas also improve my circulation, inversions, head stand legs up the wall, help the blood flow. I find it more powerful the more I practice. Namaste! (Peace!)
