Yoga positions exercise joints, tendons, and ligaments throughout the body, increasing flexibility. While some positions target specific areas, combinations of seemingly unrelated poses work together harmoniously to create flexibility. Studies show yoga benefits those with depression, psychiatric conditions, and sleep problems by stimulating oxytocin and serotonin production. Multiple studies found yoga more effective than usual care for chronic back pain by improving function and flexibility. Yoga also helps detoxify and boost metabolism, potentially helping eliminate hangovers faster through increased blood flow and balancing the body.
