Reduce Anxiety & Stress with the Physiological Sigh | Huberman Lab Quantal Clip

About this video

Huberman explains the physiological sigh as a real-time stress tool that does not require stepping away from a stressful activity: two inhales followed by an extended exhale, typically both inhales through the nose and the exhale through the mouth. Huberman explains that the pattern occurs spontaneously when carbon dioxide builds up, and that the second inhale reinflates collapsed tiny lung sacs, allowing more carbon dioxide offload. He says one to three sighs typically suffice to bring stress down quickly.
