Metro UK asks, what are sleep stages and what do they mean?
As you get older deep sleep comes less important. After all, you’re no longer growing and your body can’t repair itself as well.
This is why young children seem to get much more deep sleep than adults.
The average adult only needs about two hours of deep sleep a night, but keep in mind that you can only achieve deep sleep if you have a full and decent sleep cycle, so do NOT take this to mean you only need two hours of sleep a night – it doesn’t work like that!
