Cyclic sighing, also known as the "physiological sigh" or "double inhale", is an innate breathing pattern that we do all the time involuntarily about every 5 minutes, including the moments before we are about to fall asleep, during sleep, and when we cry. It has recently been adapted by Andrew Huberman into a breathwork practice aimed at reducing stress and anxiety.

IMPORTANT: Do the breathing exercise while sitting or lying down on a couch or bed – never in a situation that could put you in danger if you were to faint, such as in water, in the bath, or while driving.

If the breathing speed is too rapid for you, or you begin to feel lightheaded, we recommend slowing the video speed to 75%.
