Doctor reveals what happens if you sleep too much — and it's almost as bad as not sleeping enough

A woman with long brown hair sits up in bed covered in a pink comforter and yawns because she is so sleep deprived.

Have you ever woken up feeling groggy, only to realise you’ve slept for over nine hours? For some people getting too much sleep is a rare dream, for others it’s a habit they’re trying to curb. But should you stop? And how much sleep is too much?

While we’re used to being told that the average adult needs seven to nine hours of sleep per night, the amount an individual actually needs depends on a lot of different factors. These include their gender, lifestyle, and age. We know that not sleeping enough can have serious consequences, but what about sleeping too much? Well, it turns out it might be just as bad.
