Stanford neuroscientist Andrew Huberman reveals 10 daily protocols to optimize sleep, focus, stress, and metabolism—supported by rigorous science yet simple enough to implement immediately. From morning sunlight exposure that boosts testosterone to a neurological eye-movement trick that accelerates sleep onset, Huberman combines neurobiology with practical tools grounded in peer-reviewed research, addressing why most health advice fails and what actually works. Morning sunlight exposure within the first hour of waking spikes cortisol to healthy levels, boosting mood and focus while establishing the low nighttime cortisol necessary for quality sleep and stress resilience.
