The app revealed that women sleep more than men!

Women sleep longer -about half an hour, on average – than men, as usually fall to the bed earlier and waking up later, which is most intense at the ages of 30 to 60 years old.
The middle-aged men are the ones sleeping less than all of the women under 25 years of age those who sleep more than everyone.
This reveals, among other things, a pioneering international scientific research, which studied the habits of people around the world, combining elements from a free app “smart” mobile phone (called Entrain), large databases (big data) and statistical techniques.
The researchers, headed by the mathematician Daniel Φόρτζερ of the University of Michigan, who made the relevant publication in the journal “Science Advances”, studied the influence of biological, social and other factors in bed, collecting sample data from 5,000 people in 100 countries.
The main conclusion is that the time that people fall to sleep, is mainly determined by social and cultural factors, while on the contrary the time they wake up, depends primarily on the biological “clock” followed by the alarm clock. In general, though, the pressures of civilization predominate over the dictates of biology (the κιρκαδιανούς rhythms of the body).
Among the findings of the research are the following:
– The less-sleepyheads are the people who live in Japan and in Singapore, where the average duration of sleep is 7 hours and 24 minutes, and most of all sleeping the Dutch (8 hours and 12 minutes on average) and the Australians (8 hours and 10 minutes).
– Everywhere in the world, the middle-aged sleep less, usually less than the recommended seven to eight hours. As people get older, the sooner they go to sleep and the sooner they wake up.
– Those who spend a few hours a day in the countryside under the sun, usually fall early into bed to sleep and sleep more, compared with those who spend most of the time of the day under artificial light.
– The sleeping habits of people converge as they get older: those over 55 years of age, have more similar habits in relation to those who are under the age of 30. But the habits of women are changing less than that of men, as the years pass.
The study -which was funded by the Army and the Air Force of the united states – points out that the lack of sleep (for those who sleep less than seven hours) accumulates and creates a “sleep debt” over time, which increases the risk for obesity, diabetes, hypertension, heart disease, stroke, stress etc.
