Chandra Bhedana Pranayama ~ Moon Piercing Breath.
Chandra Bhedana is not usually among the formal techniques listed in traditional texts, though it is believed that this practice has the opposite effects of surya bedhana/sun piercing breath; it quiets the brain, calms the mind and cools the body.
This technique should be avoided if you have asthma, low blood pressure, cough, cold or respiratory problems. (If you have one of these conditions, we encourage you to continue the practice of breath observation that we begin our pranayama practice with).
Chandra Bhedana should not be practiced on the same day as Surya Bhedana.
This technique should only be practiced during the summer, and should be avoided in winter.
