When we're stressed, our breathing becomes shallow and some of the alveoli in our lungs can collapse, which increases the carbon dioxide levels in our blood. The abundance of carbon dioxide causes us to feel stressed and agitated, which is why taking deep breaths can feel calming.

The physiological sigh is a rapid breathing technique proven to reduce acute stress and anxiety. It involves a double inhale (a deep breath followed by a short top-up breath) through the nose, followed by a slow, extended exhale through the mouth.

This intentional breathwork triggers the parasympathetic nervous system to immediately lower your heart rate and calm your nervous system.

Neuroscientist Dr. Andrew Huberman stated that the physiological sigh could serve as an anxiety-reducing tool by giving the individual autonomy and control.

壓力時呼吸變淺，部分肺泡可能萎陷，血液中二氧化碳濃度上升。二氧化碳過多會讓人感到緊張與躁動，因此深呼吸會有鎮定效果。生理嘆息是一種經證實能減輕急性壓力與焦慮的快速呼吸法：先用鼻子做一次深吸，再補一次短吸，然後用口慢慢長呼氣。這種刻意的呼吸會啟動副交感神經，立即降低心率、平復神經系統。神經科學家 Dr. Andrew Huberman 指出，生理嘆息還能讓人恢復自主感與控制感，從而減少焦慮。
