In the long term, too little restful sleep poses a serious health risk. According to a pioneer in sleep research, the American William C. Dement, 90 percent of our health is related to sufficient, good sleep.
Unfortunately, many people in Germany can only "dream" of a good night's sleep. According to a study by the Robert Koch Institute, a third of the adult population suffers from problems falling asleep and staying asleep three times a week or more often. In a survey by DAK-Gesundheit, 80 percent of adults complained of sleep problems.
