Ardha chakrasana is an effective posture for reducing stress and aiding posture by reversing the habitual pattern of slumping forward and rounding the shoulders. It helps to release the neck and shoulders, relieving tension.
It is thought to regulate the blood pressure, particularly for those suffering from high blood pressure. This asana is also said to have a cleansing effect on the nervous system.
On an energetic level, this posture energizes the muladhara (root) and anahata (heart) chakras because of the stability required for the pose, and its heart-opening action. Ardha chakrasana (like all backbends) is thought to awaken kundalini and bring the energy of the body up through the spine. If blockages such as emotional issues are encountered here, this can cause difficult feelings to surface.
It is recommended that backbends be practiced gently, only moving deeper as the body and mind are ready.
