Commit To At Least 7 Hours
It’s true that there’s no magic number of hours of sleep that every adult must get, but in general,most people require about seven to nine hours
to feel and function their best. Risk for a number of the serious consequences of short sleep, like heart problems and obesity, increases dramatically when people get fewer than six hours a night
Calculate seven hours back from the time you need to wake up, then hit the hay as close to that time as possible. Take into consideration how long it takes you to fall asleep and whether or not you wake up frequently throughout the night.
