Essentials: Using Your Nervous System to Enhance Your Immune System

In this episode of Huberman Lab Essentials, Andrew Huberman discusses the immune system, its interaction with the nervous system, and actionable strategies for enhancing immune function. He explains the three layers of immune defense: physical barriers like skin and mucus, the innate immune system for rapid response, and the adaptive immune system for creating antibodies. He emphasizes maintaining a healthy microbiome through nasal breathing and fermented foods. Huberman also delves into "sickness behavior," driven by the vagus nerve, and explores methods to boost the immune system, such as elevating feet during sleep to enhance the glymphatic system. He analyzes a study on cyclic hyperventilation (Wim Hof breathing) and its impact on reducing inflammation via adrenaline release, and discusses the role of dopamine and a positive mindset in recovery. Finally, he touches on alternative treatments like spirulina for reducing congestion.
