Through meditative yoga, you can learn to turn off the noise inside your head and focus on your breathing, an incredibly calming activity. John Denninger, a psychiatrist at Harvard Medical School, has been leading a study on the link between yoga and the reduction of stress and disease on the body. Denninger says that "the kinds of things that happen when you meditate do have effects throughout the body, not just in the brain.” Meditative yoga helps you inject the silence you never knew you needed into your otherwise busy life. Just try not to fall asleep in Shavasana pose (easier said than done!).
