Physiological Sigh

A rapid stress-reduction breathing technique that quickly lowers CO₂ levels and calms the nervous system. This is the body's natural way of resetting during times of stress.

Source: Based on Huberman Lab protocols. This breathing pattern naturally occurs during sleep and times of stress. Research shows it rapidly reduces autonomic arousal by offloading carbon dioxide and engaging lung stretch receptors.
