LONDON — When it comes to sleep, women are the ones who are getting more sleep, according to a study.
A new study published in the journal Sleep has found that women sleep a lot better at night than men, while men are more likely to stay up late.
Women were also found to have higher levels of melatonin and norepinephrine, two hormones linked to the natural sleep-wake cycle.
“The finding is really exciting,” said study author Sarah P. Johnson, a research scientist at the University of Michigan Sleep Center.
The researchers analyzed data from more than 7,000 participants in the United States and Canada.
They found that, in general, women had about one to two hours less sleep than men during the day.
The study looked at sleeping patterns in schools, colleges, hospitals, nursing homes and other settings.
The results showed that women slept more in their dorms than in their bedrooms, which could be related to the fact that students were more likely than men to be sleeping in their own beds, Johnson said.
In addition, men tended to spend more time in their rooms than women.
Women tend to stay in their beds more than men because it allows them to sleep more comfortably, Johnson explained.
“It’s not that women are more lazy or that they need to be lazy,” Johnson said in a telephone interview.
“There’s nothing wrong with sleeping in your bed.”
A study published last year found that while women are often the ones taking the long walks around the campus, men can be more active and spend more of their time outside, according the British Medical Journal.
The finding that men are able to stay more active, as opposed to women, could be linked to increased levels of testosterone and melatonin in the brain, Johnson and colleagues wrote.
The research, which was funded by the National Institutes of Health and the European Union’s Seventh Framework Programme, was published online in the European Journal of Endocrinology.
