How many hours of sleep per night does a human being need to be healthy?
I bet you've answered eight hours, but that's not quite true according to recent scientific findings.
This is misunderstood.
That's like saying everybody should be five feet ten inches tall and if you're shorter than 5'10, you've got a problem.
Not all of us need the same amount of sleep to be well-rested and function at a high level.
And it's not a matter of behavior or choice.
It's in the genes.
Some people are genetically designed to be what is called 'natural short sleepers'.
This means they only need four to six hours of sleep per night and still wake up feeling fresh.
Others have called these folks 'elite sleepers', and I think it makes sense.
