Happiness Break: A Breathing Technique to Help You Relax

Oct 15, 2026 · 8m

Summary

Host Dacher Keltner and Stanford’s Dr. David Spiegel guide listeners through a "cyclic sighing" breathing practice rooted in Eastern traditions. The episode explains how this technique regulates the nervous system by balancing oxygen and carbon dioxide to lower arousal and improve blood flow. Through a guided session, the hosts demonstrate how a rapid diaphragmatic inhale followed by a slow, extended exhale can quickly reduce stress, anxiety, and muscle tension.
