Breathing is vital to life, but did you know the way you breathe can be used as a cheat code to vitality? Breath work has been the recipient of some much well deserved attention lately. You may have heard of deep breathing or box breathing, but one breathing technique stands out above the rest. Enter the physiological sigh (or cyclic sighing if done on repeat). This sigh isn’t your typical exasperated "why me?" sigh that you let out when your drink spills. A physiological sigh is essentially a double-inhale followed by a long exhale. It’s a natural pattern of breathing you may have noticed yourself performing after a good cry. That’s because the physiological sigh has been known to help your body move from “fight or flight” to “rest and digest” or “chill and heal” via the parasympathetic nervous system, making the physiological sigh a sort of super hero. Humor alert: If sighs were a superhero, they'd be "Captain Reset"—swooping in to save the day from emotional villains like "The Overthinker" or "Deadline Doom." And unlike caffeine, they won't leave you jittery—just joyfully zen. From what mechanisms does the physiological sigh gain its super powers? Well, I’m glad you asked.
