In this Huberman Lab Essentials episode, I explain how the immune system defends against infection and describe the relationship between the immune and nervous systems. I discuss the immune system's three primary layers of defense, emphasizing how each contributes to protection from infection. I share practical tools to enhance immune function and accelerate recovery from sickness, including specific breathing patterns, sleep positioning and targeted supplementation. I also explore the powerful mind-body connection, showing how mindset and nervous system activation can directly influence the body's ability to heal.
