AMA #2: Improve Sleep, Reduce Sugar Cravings, Optimal Protein Intake, Stretching Frequency & More

About this video

In this Ask Me Anything episode, Huberman answers questions about improving sleep, reducing sugar cravings, optimal protein intake, stretching frequency and more, with the opening excerpt devoted to deep sleep. He explains deep or slow-wave sleep dominates the first half of the night while REM sleep dominates the second half, that growth hormone is secreted during deep sleep mostly in that first half, and that deep-sleep dreams tend to be less emotional than REM dreams. Responding to a listener whose tracker showed much REM but little deep sleep, Huberman discusses a randomised crossover study he describes in which an hour of moderately challenging exercise, done well before bedtime with caffeine and alcohol abstained from, enhanced slow-wave sleep, even though participants did not subjectively feel much better, and he stresses slow-wave sleep’s role in body and brain repair.

Key takeaways

• Huberman describes moderately intense exercise well before bedtime as enhancing slow-wave sleep in a study he reviews.
• Huberman advises avoiding caffeine and alcohol before bed to protect sleep architecture.
• Huberman stresses slow-wave sleep supports repair of body and brain tissues.
