Kapalbhati pranayama is considered an intermediate to advanced breathing technique. It is believed to cleanse the internal organs, energize the nervous and circulatory systems, as well as improve metabolism. In addition, many yogis practice this pranayama technique in order to clear the nadis.
Kapalbhati pranayama increases oxygen supply in the body, which can promote clarity of mind and focus. According to Hatha yoga practitioners, the kapalbhati technique cleanses the body of all impurities.
Advanced yogis may wish to practice kapalbhati pranayama while incorporating the three bandhas. Yogis experiencing faintness or dizziness while practicing kapalbhati pranayama should cease.
