Using Temperature for Performance, Brain & Body Health | Dr. Craig Heller

In this episode, I am joined by Dr. Craig Heller, Professor of Biology at Stanford University and world expert on the science of temperature regulation. We discuss how the body and brain maintain temperature under different conditions and how almost everyone uses the wrong approach to cool off or heat up. Dr. Heller teaches us the best ways and, in doing so, explains how to offset hyperthermia and hypothermia. He also explains how we can use the precise timing and location of cooling on our body to greatly enhance endurance and weight training performance. He describes how cooling technology discovered and engineered in his laboratory has led to a tripling of anaerobic (weight training) performance and allowed endurance athletes to run farther and faster as well as to eliminate delayed onset muscle soreness. Dr. Heller explains how heat impairs muscular and mental performance and how to cool the brain to reduce inflammation and enhance sleep and cognition. We discuss how anyone can apply these principles for themselves, even their dogs! Our conversation includes many practical tools and mechanistic science.
