> "Based on ... about 10,000 empirical scientific studies, the number of people who can survive on six hours of sleep or less without showing any impairment, rounded to a whole number ... is zero." This statement made me think about reports of successful people wherein one supposed factor to their success was ability to "function" on less sleep (Marissa Mayer 4 hours, Jon Gruden 4 hours, Tom Ford 3 hours)

Some of those successful people are just faking it, or fooling themselves. But there are at least two "short sleep" genes which allow people to be rested in about 6 hours instead of 8.

> maybe that's also just coming from my own experience of sleeping extra well in higher end hotel beds than my own bed at home. Not trying to argue with you about your experience or anything, but I think it's possible that certain elite athletes have different needs. Just as a thought exercise, think back to all those high end hotels you've stayed in, and try to remember the comfy beds. Now, would those beds have bee…

i'm pretty sure they've all figured out to sleep on the diagonal (which should give them 8-9ft) by this point in their lives. those overly-soft beds tend to make me overheat more.

Presumably they have all figured out that they don't need to sleep on the diagonal but that they can simply buy custom extra-long beds in every place they live... except hotels.

I don't know about others, everyone seems to like naps, but I feel completely wasted after midday sleep.

Are you sleeping for exactly 1 sleep cycle, which for most people is roughly 1.5 hours, of which only the middle half hour is deep sleep. If you set your alarm for an hour, you will probably be woken in your deep sleep and be "wasted". Similarly, if you extend your nap to 2 hours and fall into the second deep sleep.

I know the concept of deep sleep and cycles but how the hell could you plan this? Like ok, I'm sleepy due to lack of sleep, now I have a certain stretch of time with no time constraints - how do you know when you will fall asleep, when will enter deep sleep phase and whe will it end? I have no idea about any of those numbers.

There are mobile apps or fitness watches/bands that apparently can tell your sleep state based on your movement etc. I don't know how accurate they are because my phone is cheap with cheap sensors.

You tell these apps what time you want to wake up at the latest, and they will ring the alarm before that time when you are not in deep sleep.
