Spent 3 hours or so rereading 1st chap of WWS, dug into Alexey's post and papers he cited. Overall points: - MW published some factually erroneous claims, but his message is in the right direction - If you are young & fit you should def sleep ~7.5 hrs https://delian.substack.com/p/d7-sleep-matters-but-alexey-guzey …https://twitter.com/alexeyguzey/status/1195380402078265345 …

For the last two months I've been sleeping for 4 hours a night, thinking about Matthew Walker's "Why We Sleep". 130 hours of writing and research and 6000 words later: https://guzey.com/books/why-we-sleep/ …

The issue with the critique is that he criticizes "meaningless correlational studies" but still uses them to come up with his conclusion. I do sleep optimization in private practice with CEOs & VC. I rec. 7-8 min, 8-10 with heavy physical/mental activity.https://twitter.com/DrSepah/status/1189694113714622464?s=20 …

Replying to @jerryteixeira

1/ Best practices for SLEEP optimization: The claim that 60-67°F is the optimal sleep temperature is misleading. I've actually reviewed the research: there is no universal optimal, because it depends on your sheets, clothing, body fat/temperature, wind/fan speed, & humidity.
