Normally, your heart works against gravity; inverting your entire body lessens the strain on your heart, and allows a plentiful supply of oxygen-rich blood to reach your head and brain. Headstand, and other inverted position, increase circulation, stimulate the brain, enhance glandular system functioning, and relieve pressure on the abdominal organs.
