Physiological Sigh

Shrink Definition

The physiological sigh is a natural breathing pattern, a double inhale followed by a long exhale, that quickly calms the body. The body does it on its own during sleep and after crying, and doing it deliberately can lower stress fast. The extended exhale activates the calming branch of the nervous system. A few of these breaths can settle acute stress in moments.
