The Mayo Clinic reported findings from a recent study indicating that meditative techniques associated with Tai Chi and yoga positively affect immune system health. Researchers note that the benefits of these mind-body approaches stem from their combination of key exercise elements and mindfulness techniques. The positive benefits of these mind-body treatments range widely from stress-reduction to improved sleep, better digestive health, and slowing the aging process. The stress-reduction qualities in particular, as well as lowered blood pressure, also result in the enhanced overall health and functioning of the immune system. The common elements in both yoga and tai chi include meditation, breathing, and different physical movements.
