Matt welcomes UCSF sleep expert Dr. Aric Prather to the podcast this week to discuss the science of psychoneuroimmunology: the link between our behavior and immune health. After a primer on the immune system’s innate and adaptive arms, Dr. Prather details how insufficient sleep dramatically increases your risk of catching a cold, significantly blunts vaccine effectiveness by reducing antibody response, and promotes a state of chronic, low-grade inflammation - a known pathway to numerous age-related diseases.
Ultimately, the conversation illuminates a profound and actionable truth: sleep is arguably our most powerful, yet tragically overlooked, weapon in the daily battle for immunological health.
