Humans sleep through around a third of their lives. And that's important too, because he needs energy for the other two thirds. But how well do we really sleep? How do people in Germany rate the quality of their night's sleep? What sleep aids you can't do without? And what can possibly rob them of sleep? To get answers, we had commissioned an exclusive survey for issue 2/20 of our printed magazine.
An overview of the survey
In our exclusive survey, we had 1,006 people in Germany asked over the phone about their sleeping habits and sleep hygiene. 49 percent of the participants were male, 51 percent female. The respondents include representatives of all ages from 14 years, all educational and income groups and from all German federal states. 66 percent of the participants live in urban regions with over 100,000 inhabitants.
Among other things, this cross-section of the population wanted to know:
- How many hours do you sleep on average per night?
- When do you go to bed most of the time?
- How do you rate the quality of your sleep?
- For people who have not rated their sleep quality as "Top! I sleep deeply and firmly": What is preventing you from falling asleep / staying asleep?
- What aids do you use regularly to fall asleep?
- What do you do in bed besides sleeping?

Why is good sleep so important?
Anyone who has slept too little or badly knows the first reactions of the body. Fatigue weakens performance and concentration. In the long run, lack of sleep can have even more serious consequences: the immune system is weakened, the body becomes more susceptible to diseases. The memory can be impaired. In extreme cases, hallucinations and delusions can occur, warns the health insurance technician .

How much sleep does the body need?
The number of hours of sleep required per night varies from person to person. However, numerous studies have shown that most people need between seven and nine hours of sleep to feel awake and well-rested during the day. The actual sleep time of most Germans is just below this: In the survey of 61 percent of those surveyed stated that they slept between six and eight hours a night.
The result is in line with a study by the Organization for Economic Cooperation and Development (OECD): Compared to citizens in 17 other countries, including France, Korea and Australia, Germans tend to be among those with an average sleep duration of eight hours and ten minutes Short sleepers.
But if you occasionally sleep little or poorly, you do not have to worry about your health immediately:
"A doctor speaks of poor sleep if you cannot fall asleep more than three times a week, need more than half an hour to fall asleep or cannot sleep through, and take more than half an hour to fall asleep again."
If you have trouble falling asleep, experts say you should first try to "shut down" with fixed rituals:
"For example, reading for half an hour in the evening, listening to radio plays that don't excite you, or going for a walk to switch off."
Other activities, in turn, can negatively affect sleep quality:
"In general, activities should be shut down in the evening. No sport after 8:00 p.m. Plenty of food and alcohol should be avoided in the evening as well as nicotine. Flight mode should be activated on electronic devices such as cell phones or tablets."
