alt Hacker NewsOne additional quirk of the modern world is that we now sleep on average one hour less than a century ago (median of 7,5 instead of 8,5). Sleep science says this is probably ok ish but really actually not. If you’re constantly tired just remember 8 hours of sleep was invented 60 years ago…
For me, sleep before midnight is the most important factor. If I need my brain working well the next day, all I need to do is go to bed by 10PM. Even if I wake at 5:30, it will be fine.
BTW, nights were I have dream recall afterwards, are the best. Anyone else have made the same observation?
