I found the Peter Attia Drive three-part sleep podcast with Matthew Walker to be most fascinating. I first heard him on Joe Rogan and also on Rhonda Patrick, but this conversation with Peter Attia is the most comprehensive.
#47 – Matthew Walker, Ph.D., on sleep
– Part I of III: Dangers of poor sleep, Alzheimer’s risk, mental health, memory consolidation, and more
#48 – Matthew Walker, Ph.D., on sleep
– Part II of III: Heart disease, cancer, sexual function, and the causes of sleep disruption (and tips to correct it)
#49 – Matthew Walker, Ph.D., on sleep
– Part III of III: The penetrating effects of poor sleep from metabolism to performance to genetics, and the impact of caffeine, alcohol, THC, and CBD on sleep
There's also a bonus AMA esoisode, but I'm not a subscriber so haven't heard more than the teaser:
#58 – AMA with sleep expert, Matthew Walker, Ph.D.
: Strategies for sleeping more, sleeping better, and avoiding things that are disrupting sleep
The take-home message is what we probably can intuit, but probably don't often practice: that sleep should be regular, long, uninterrupted, and deep. Just like many other things in life!
