So make sure you get enough sleep and create a sleeping atmosphere where you are not disturbed and can really relax. Allow your body, mind and soul the rest they need. Getting enough good sleep is important for staying fit, productive and healthy in the long run.

How much sleep is ideal?

It is impossible to say in general terms how many hours of sleep are ideal. Sleep needs are not the same for everyone. There are short sleepers and long sleepers who need different amounts of sleep. Studies on the relationship between sleep and health suggest that most individuals should aim to get betweenseven and eight hours of sleep per night. Sleeping much less or even too much can have negative effects on your health. As a rule of thumb, if you can work with concentration during the day without feeling sleepy, even after sitting for long periods, you have probably found your ideal amount of sleep.

Sleep duration types1

Type Duration Prevalence
Short sleepers <6 hours approx. 20%
Medium sleepers 6-8 hours approx. 65%
Long sleepers >8 hours approx. 15%

If you regularly do not wake up refreshed in the morning, even though you have slept long enough, a visit to the doctor may be advisable: For example, chronic daytime sleepiness can be caused by obstructive sleep apnoea (OSA). In this disorder, sleep architecture is disturbed by repeated pauses in breathing.


Sleep disorders can result in physical and mental illnesses and, conversely, both physical and mental illnesses can cause sleep disorders. For example, depressive moods are closely linked to sleep disorders. It is important to recognise sleep disorders at an early stage, because there are good therapy options.
