Physiological Sigh or Cyclic Sighing (with rain)

A gentle guide to help you activate the parasympathetic nervous system, which has an overall soothing effect on the body. Breathe in through your nose. When you've comfortably filled your lungs, take a second, deeper sip of air to expand your lungs as much as possible. Then, very slowly, exhale through your mouth until all the air is gone. You are safe.
