Napping sleep increases efficiency
A nap in honor should deny nobody. Also not at lunchtime, and not at work, say doctors. A Viennese study shows that a short afternoon nap increases performance in the following hours by a remarkable 25 percent. MEDICINE popular asked why that is and how best to keep siesta.
Do you know that? In the late morning, a yawn announces the midday low, it becomes increasingly difficult to think straight, and – yawn! – It would be best to sleep a bit now. But what is normal in southern European countries – keyword “Siesta” – or even in Japan, is not welcome in this country. And for those who are in the midst of the work process, in most cases it is simply impossible to disconnect, to yield to the need for sleep, or even to rest a little.
Doctors strongly advise everyone to take the opportunity to siesta. Why do you do that? Univ. Prof. DDr. Michael Lehofer, director of the psychiatric department at the Sigmund Freud Clinic in Graz and vice president of the Austrian Sleep Society, says: “When we sleep at noon, our physical and psychological performance increases.” In a study by the Fund for the Advancement of Science Research could even be quantified this increase. “We’ve shown that someone who has a midday low and then takes a nap can then do up to 25 percent more than if he does not sleep,” Dr. Cornelia Sauter, Clinical and Health Psychologist at the Department of Neurology at Vienna General Hospital.
This has been found in subjects who had to master skill and memory tasks. The nap during the day, as shown by the results, serves not only the subjective feeling, but also according to scientific criteria of the recovery of mind and body.
Who needs how much sleep?
How much sleep a person needs, whether he goes through life as a morning or evening man, is given by nature. The final personal sleep duration is set at the age of 20 and remains stable until old age. The range in terms of sleep requirement is large: Some come out with four hours, others feel comfortable only when they have slept twelve hours. From the age of 25, there is a gradual decrease in vitality, the need for recovery is slowly increasing. Almost two-thirds of the over-65s also regularly sleep at lunchtime. Anyone who has taken a nap at night needs the amount of less sleep he has slept during the day.
Sleep or break
In a recent study, currently under the direction of dr. Cornelia Sauter is running at the Vienna AKH, it is being investigated whether a midday sleep is actually superior to the rest period of the same duration, in order to get body, mind and soul going again. In addition, one wants to find out how the duration of recovery periods affects the quality of recovery.
The course of study includes a sleep anamnesis, that is an accurate record of sleep, and a documentation of sleep behavior during the day and at night. On a total of six examination days, subjective well-being, concentration and attentiveness are assessed before and after a nap or a break (10, 20, and 30 minutes each).
Forty subjects between the ages of 18 and 30 go through all six conditions in random order. The results are expected in the coming months.
