Free Protocol: Physiological Sigh

Our breath is something we take for granted but one of the most effective tools we have for collaborating with our nervous system.

Tapping into our breath and changing it can shift our state instantly.

This breath practice: the physiological sigh, is incredibly simple and immensely effective for cultivating calm.

It involves a full inhalation through the nose, breathing into the back of the chest, and when you're full, you top up. And that's followed by completely relaxed exhale out the mouth.

Repeat this a few times and notice what it does to how you feel.
