17.05 - sleep

"Everyone needs the standard 8 hours of sleep a night." This would be great and make it simple to understand our bodies' needs, no?

Unfortunately,  humans are MUCH more complicated and we are all different. Not everyone requires 8 hours of sleep a day. Not only that, just because you need 8 hours of sleep tonight does not mean you will need 8 hours of sleep tomorrow night or even next week!

I use this other app, Evidation, to track some health metrics. It had this article on how much sleep a person needs -->
