Mentioned in the yogic text, "Hatha Yoga Pradipika," Bhastrika is said to be ideal for moments when one feels hazy or confused, or when one seeks to gain clarity in a particular area. This is because the breathing technique is thought to purify the mind and clear energy blocks. Long-term practice may even awaken an individual’s higher powers.
Bhastrika increases metabolism and improves digestion, which may help with weight loss. It is best practiced on an empty stomach, as it stimulates circulation and blood flow to all organs of the body. A milder version of bhastrika is kapalabhati, which also has cleansing and energizing properties.
Unusual for a pranayama practice, bhastrika neither raises nor lowers body temperature, but rather maintains it.
