What is the physiological sigh?

The physiological sigh is a quick way to calm down that your body already does on its own. You take a normal breath in through the nose, add a second short sip of air to fully inflate the lungs, then let out a long, slow exhale through the mouth. Even one or two rounds can take the edge off stress in the moment, and research from Stanford has linked this kind of cyclic sighing to lower stress and improved mood. It is fast, discreet, and needs no preparation. StillMind can weave breaths like this into a short reset session.
