Physiological Sigh

This type of breathing can help calm the nervous system and reduce stress.

Inhale slowly through the nose to fully expand the lungs, then take another short inhale on top of this breath, next exhale slowly through the mouth (optimally twice as long as first inhale). This simple step of taking a short breath on top of the first breath can be added to other breathing practices.

• Long Inhale - fully expand lungs

• Another short inhale without exhaling

• Long, slow exhale

Dr. Andrew Huberman and Dr. David Spiegel of Stanford School of Medicine published a clinical trial showing that "cyclic physiological sighs, practiced daily for 5 minutes, reduce overall stress, promote relaxation, improve sleep, lower resting heart rate and enhance mood." -Breathwork Protocols for Health, Focus & Stress
