Parivrtta janu sirsasana is often included toward the end of a yoga class when the body is open and the mind can absorb all the benefits of its relaxing and stimulating stretch.
It is considered therapeutic for a wide range of conditions, including anxiety, depression, headaches and fatigue. Some people also find it relieves insomnia.
As a powerful hip and groin opener, parivrtta janu sirsasana works to balance and activate the svadisthana (spleen or sacral) chakra, which is connected with the element of water. This is thought to cultivate both freedom of movement and self-nurturing qualities. The twisting element of the posture also stimulates the manipura (solar plexus or navel) chakra.
