In this Huberman Lab Essentials [https://www.hubermanlab.com/essentials] episode, I discuss science-supported tools to improve sleep by supporting a healthy circadian rhythm using key behaviors and environmental cues. I explain specific morning, afternoon and evening behaviors that will increase daytime alertness and support deeper, more consistent sleep at night. I also cover sleep supplements, the effects of caffeine, alcohol and THC on sleep, as well as practical strategies for managing jet lag and shift work.
