The idea of this type of breathing is based on a yogic breathing technique: Pranayama Breathing. 

Pranayama is a Sanskrit word formed by two words. Prana means a subtle ‘life-force’ / ‘vital energy’ / ‘breath of life’ which gives energy to the mind and body (it is also translated as the substance of the astral world) and ayama which signifies the voluntary effort to control and direct life-force or prana.

Pranayama is essentially a process by which prana is controlled by regulating the breathing voluntarily. It involves a temporary pause or interval in the movement of breath. 

Pranayama, therefore, means “extension of life force.”
