I would love to see studies like this that further explore the relationship between length of time spent sleeping and health/behavioural benefits. For this study, did they choose 8.5 and 4.5 hours arbitrarily? Probably not, but a comparison over more gradated time intervals would be really interesting.

Coincidentally I can't sleep longer than 8.5 hours (no matter what) and if I get 4.5 hours of sleep or less I'm absolutely worthless. I'd have qualified for the study if it wasn't for that damn athletic requirement!

  I think there is quite a body of literature around why 8-8.5 hours is a good amount, what I really want to see is what the different benefits as functions of sleep time looks like. That information would be invaluable for doing a min-max optimisation. 6 hours tends to be my reasonable 'short sleep' time, where anything less and I am significantly tired during the day, but I am easily capable of sleeping all day if the opportunity arises. Usually, however, I think I get 7-8 hours, which tends to be ok. A big factor also seems to be breathing function throughout sleep. I think I breathe poorly while sleeping and so don't have quite as good a sleep as I could otherwise.

    > where anything less and I am significantly tired From what I have read, the ideal amount of sleep needed is quite personal and some people are fine with 6 to 7 hours while others just need 9 - but pretty much all studies consistently showed that less than 6 is definitely not enough and when sleeping less than 6 hours for a longer time you might even have hallucinations and at the very least your overall performance will suffer. So I think you are doing it right. You might want to experiment with those 90 minute sleep phase calculations like sleepyti.me or others. > A big factor also seems to be breathing function throughout sleep Absolutely! Sleep apnea is VERY serious and one of those things that prevent you from getting a good night of sleep for a lot of (very) large people.
