How much deep sleep and light sleep should I be getting?
Some people require a solid twelve hours of sleep a night, while others are happy with a three hour nap.
The amount required is completely dependent on who you are, and tends to be between four and eleven hours each night.
The advice usually given by experts is that if you’re feeling tired in the daytime, you need more or better sleep.
However, there are two different types of sleep (deep and light) and you should really be getting over a certain amount of the deep kind.
The difference between light and deep sleep
While sleeping, there are two stages your body will go through.
These are called non-REM sleep – the light sleep – and deeper, REM (which stands for Rapid Eye Movement).
Your eyes move quickly in all directions when you’re in REM sleep. For non-REM stage, your eyes won’t move a lot.
