How Your Immune System Works & How to Improve It | Dr. Max Krummel
Summary
Andrew Huberman interviews immunologist Dr. Max Krummel to explore the immune system’s role in health, aging, and disease. They discuss how the body distinguishes self from non-self, why immune function declines with age due to cellular mosaicism, and the thymus’s critical role in T-cell development. The conversation also covers how sleep, memories, and vaccines influence immune responses, offering actionable insights for maintaining robust immunity throughout life.
