Study: Human sleep hours decrease to their lowest rates in middle age

 A joint research team from England and France concluded that people sleep fewer hours in the middle-aged period, between the early thirties and early fifties.

The study, conducted by researchers from the Universities of London College, Anglia, and Lyon, France, and published in the scientific journal Nature Communications, revealed that sleep hours gradually decline from the beginning of puberty until it reaches its lowest levels at the age of 33, and then begins to gradually increase again after he reaches puberty. The person is 53 years old.

The study included more than 730,000 people from 63 countries, and included engaging them in a video game on smart phones called "Sea Hero Quest" to measure their various neurological abilities, and then subjecting them to questionnaires to find out their sleep patterns and hours, in addition to other questions within the framework of this research project. expanded.

The researchers found that men sleep an average of 7.01 hours each night, and women sleep 7.5 hours longer.

It was also found that the younger volunteers (at least 19 years old) slept the longest, and that the volunteers' sleep hours declined at the age of twenty until thirty, before stabilizing from the beginning of the age of thirty until the beginning of the fifty, and then began to rise again.

The researchers stated that the decline in the number of hours of sleep in middle age may be due to the demands of childcare and career life.

And the website "Medical Express", which specializes in medical research, quoted researcher Hugo Spears, a specialist in psychology and language sciences at University College London, as saying, "Previous studies have monitored a relationship between human age and hours of sleep, but this new study is the first of its kind to identify the link." between age groups and different hours of sleep.

"People sleep fewer hours in middle age, but the average number of hours also varies in different countries and regions around the world," he added.
