Dr. Andrew Huberman provides a masterclass on all things sleep: what makes you sleepy, what actually happens during deep vs. REM sleep, and most importantly, how to optimize your nightly rest. He offers a toolkit of science-backed tips – from viewing morning sunlight and limiting evening light, to specific supplements and “NSDR” (non-sleep deep rest) protocols – that can help anyone fall asleep faster, sleep more soundly, and wake up feeling truly refreshed. If you’re looking for a clear plan to upgrade your sleep, this episode delivers a wealth of practical advice.
