Penn State Researchers Say We May Need 8.5 Hours Of Sleep A Night.

How many hours of sleep do you get in a night? Researchers at Penn State are saying it’s probably not enough.

Daniel Gartenberg, a sleep scientist and assistant adjunct professor in biobehavioural health at Penn State University, says 8.5 hours is the optimal amount.

Why?

According to the research, we don’t stay asleep all night.

Gartenberg says, “A healthy sleeper will only spend around 90 per cent of the time in bed sleeping, so to get the eight hours that most people need, you need to spend 8.5 hours in bed.”

You heard it! Stay in bed longer.
