The link between sleep and health

With the help of its connected products, the Nokia Health Division has conducted a large study of 200,000 people to study their sleep. This study, conducted parallel to the launch of a new product, contains some interesting data.

With an average of 7 hours and 25 minutes of sleep per night, the French are the champions of sleep. According to the results of this study, the sleep of the French is just long, it’s also of good quality. It is deep, without interruption and regular. At the bottom of the rankings are the Japanese who sleep almost an hour less per night.

This is interesting because the links between good health and quality of sleep have been known for several years and the size of the data collected by Nokia allows to better specify them.

Thus, two-thirds of the people who sleep poorly — in quality or in quantity — are overweight and the short sleepers are also more prone to hypertension. Results that confirm and specify the different scientific studies conducted on this subject.

More anecdotally, this study also makes it possible to draw a map of the early sleepers of the planet. The Germans, the English, the Americans hit the bed quite early; at around 23:30 on average.

In contrast, the Spanish, the Chinese and the Japanese are real night owls. They go to sleep on average at around 12:30 am.
