But it is not only the age that determines the individual sleep duration. Fitness and some personal things, such as illnesses, also play a role.
How much you should really rest, you can find out for yourself with a little experiment. This works as follows:
- You need at least three days at a time to avoid having to get up at a specific time.
- Obey your instinct and then go to sleep when you are tired.
- Do not use alcohol and cigarettes in the evening.
- Do not set an alarm clock, just go to sleep until you wake up by your own accord and feel well rested.
- On each day of your self-experiment, count how many hours you slept and calculate the exact average.
- The result shows you how many hours your body needs for a restful sleep.
Try to always get that amount of sleep hours.
And another tip: if you sleep as long as your individual value recommends – and no more than a maximum of an hour or two – you’ll sleep better and you’ll also be in charge of getting up again.
