In this episode of Huberman Lab Essentials, Andrew Huberman discusses how to apply science-based protocols to optimize various aspects of daily life, including sleep, learning, creativity, and meal timing. He structures the information around a typical day, sharing his personal routines and the scientific reasons behind them. These include tracking temperature minimum, morning walks for optic flow and sunlight exposure, delaying caffeine intake, strategic meal timing, optimizing workspace ergonomics, incorporating 90-minute work blocks, and physical exercise. He also touches on the importance of light exposure in the afternoon and evening, as well as strategies for improving sleep quality, including temperature regulation and supplementation.
