Most people are stuck in old habits, and the body accumulates toxins and impurities according to Ayurveda, which are held in the lower abdomen.
When your body is inverted, upside down, gravity is assisting to move these stuck impurities out of our system. This allows for fresh nutrients
to replenish the old, so new growth can occur. The improved circulation and blood flow to the head while being upside down is a great way to
prevent hair loss. See Yoga for Healthy Hair.
