I put all things that might be impacting our health in a poll last day here #846592 And it wasn't surprising that there was good talk around sleep.

I'd rather have more open answer to it. Yes, sleeping less causes havoc, I agree but there's nothing much have been explored about the benefits of sleeping more than required.

Another point that I've noted is sleep patterns may differ for people, from body to body. A man may be sleeping 5-6 hours and be healthy, fit and fine. While other can be sleeping nine hours, yet can be unhealthy. There are many other constraints that determine your health.

Enough sleep is definitely not enough if you don't do it in one stretch and complete REM cycle in it.
