Understand and Use Dreams to Learn and Forget | Huberman Lab Essentials

About this video

Huberman explains sleep as a series of 90-minute cycles, with more slow-wave sleep early in the night and more REM sleep later, and assigns them different jobs. He describes slow-wave sleep as critical for motor learning and specific details, while REM sleep handles general themes, meaning and emotion, uncoupling emotional load from experiences so irrelevant associations are discarded. Huberman notes that REM deprivation leads people to see odd associations and eventually hallucinate, and draws parallels between REM, EMDR and ketamine therapies for trauma. He says alcohol and THC disrupt the depth and sequencing of sleep, and observes that consistent sleep, such as six hours every night, is better than highly variable amounts.
