EPISODE SUMMARY

In this episode of Huberman Lab, featuring Andrew Huberman, Dr. Andrew Huberman: How Breathing Activates Immunity explores harness Your Nervous System To Strengthen Immunity And Fight Infection Andrew Huberman explains how the immune system’s three main defenses—physical barriers, innate immunity, and adaptive immunity—work together to protect us from infections. He then shows how the nervous system can both trigger sickness behavior and be deliberately used to enhance immune function. Tools discussed include optimizing the mucus lining and microbiome, prioritizing sleep and glymphatic clearance, as well as specific breathing protocols that acutely shift inflammatory cytokines. He also highlights emerging research on mindset, electroacupuncture, and spirulina as ways to modulate inflammation and recovery.
