  This would be a lot better if they cited their sources. As it stands it’s interesting but a bit too easy to dismiss as SEO fodder.

  The author spent a lot of time trashing the idea of 8 hours of sleep, but at least that is something actionable people can do. I can’t set an alarm to wake me up when I’ve had enough spindle activity for the night. 8 hours is given as a benchmark, because that’s how long it takes most people’s brains to adequately do the things mentioned.

  If an article is telling me to throw out the rule book on sleep, it needs to offer new and actionable rules. Otherwise, I’m not sure what the point of this was, other than means to harvest email addresses.

  > If you’re ready to stop measuring sleep by the clock, and start enhancing the restorative function of sleep, join the waitlist and be the first to experience what functional sleep health can really mean.

  Feels like a tldr is “Hi I read some stuff about sleep please give me your e-mail”
