“Kapalabhati” is a sanskrit word and if we break down, it has two different words in it: “Kapala” means “skull”; “bhati” means “to shine or to be lustrous.” It warms up the body. This practice is said to “make the skull shine” by cleansing the nasal passageways and sinuses, and ultimately supplying the brain with a fresh supply of oxygen-rich blood. It also cleanses the throat and lungs and stimulates the abdominal muscles and organs. Best to practice in early mornings with an empty stomach.
