Breathwork
Recommended for healing the sympathetic response (fight and flight) and turning on the parasympathetic (rest and repose). We heal our bodies when we are in parasympathetic response.
Wim Hof Method—the basics of the breathwork. 1) 40 breaths in and out through the nose. 2) Release the last breath, let it out gently. 3) Then hold the breath, hold without an intake of air for as long as you can. 4) Take a deep breath and hold for 15 seconds.
I recommend the Wim Hof Method app.
Breathing through the nose is a parasympathetic breath—when we suckled as babies to eat, relax, and/or fall asleep, we were breathing through our noses.
Breathing though the mouth is a sympathetic breathing response that happens when we are hyper-aroused; for example running from a predator, having an anxiety attack, panic attack, or asthma attack. Mouth breathwork is used in practices like Holotropic Breathing and other trauma releasing techniques.
