Who sleep more, men or women? – Vanguardia Liberal

Sleeps Like the rich and the poor in the tropics and at high latitudes, but not young people and adults.

Ah, not women, who go to bed earlier and get up later.

These are some of the findings of a new study of mathematics at the University of Michigan, published in Science Advances: through an app (Entrain) people from 100 countries reported their sleep patterns, which yielded those conclusions

the researchers examined how age, gender, the amount of light received on the day and the country affect sleep, but found a uniform pattern.

among the main conclusions is that society, ie customs to circadian rhythm are imposed, being more noticeable in the time to go to bed, while the awakened play not only employment and educational obligations, but other factors such as the internal clock of each person.

most respondents said sleep 7 to 8 hours , said Amy Cochran, one of the researchers, although a pattern on this point is not had.

A across the planet, different studies have reported “a crisis Sleep” and the researchers wanted to bring you near data naturally outside the laboratory.

the study shows that going to bed later is related to a lack of sleep, according to Daniel Forger, another researcher, in a news release.

the article revealed that the average hours of sleep depends more bedtime that of waking up.

the time to go out and catch the sun and light exposure has an effect on sleep time. Women are more sensitive to changes in sunrise and sunset.

Location

But as for latitudes and high or low income, there appear to be differences.

“there may be differences, but found none in sleep patterns between high and low latitudes and among people of countries with high or low income,” said Cochran.

But there is a revealing fact: “what we found was that certain countries with geographical similarities and / or cultural shared similar patterns of sleep in terms of going to bed and waking up” .

This is the case of Canada and the United States, and Australia and New Zealand.

to go to bed, age is the determining factor, and to wake up. “Overall teens report will go to bed and get up later,” he said.

In a striking result, those who said they were more exposed to outside light to throughout the day instead of inner light, go to bed early, get up early and sleep more.

They they sleep

Other relevant findings based on this application, initially released for iOS and then Android, were:

the middle-aged are the least sleep, often even recommended 7-8 hours.

the women sleep on average about 30 minutes longer than men go to bed a little earlier and wake up a little after them, something most evident among those between 30 and 60 years old.

as people age, habits converge. Sleep schedules are more similar among those over 55 than in those under 30, which could be due to the shorter time in which older workers can fall asleep

Now, said Cochran, these findings could arise other assumptions that derive laboratory in new ways to face this crisis dream that seems a feature of modern society.
