Women Need More Sleep Because They Use Their Brain More
Do women need more sleep than men? Yes, according to Dr. Jim Horne , Britain’s leading expert in sleep science. In an article published in the Daily Mail , Horne explained that on average women need twenty more minutes of sleep than men. The researcher pointed out that women tend to multi-task and use more of their actual brain than men leading to a greater need for sleep. Essentially, the more you use your brain during the day, the more it needs to rest while asleep.
“One of the major functions of sleep is to allow the brain to recover and repair itself. During deep sleep, the cortex — the part of the brain responsible for thought, memory, language and so on — disengages from the senses and goes into recovery mode,” Jim Horne, director of the Sleep Research Center at Loughborough University in England, told The Australian. “The more of your brain you use during the day, the more of it that needs to recover and, consequently, the more sleep you need. Women tend to multi-task — they do lots at once and are flexible — and so they use more of their actual brain than men do.”
It follows that, if men used their brains more during the day, they would need a couple of extra hours too. “A man who has a complex job that involves a lot of decision-making and lateral thinking may also need more sleep than the average male — though probably still not as much as a woman,” Horne said.
The Science of Sleep
A correlation between inadequate rest and accelerated skin aging was shown in a paper published this year, by researchers from Case Western Reserve University School of Medicine. According to some other studies, poor sleeping can lead to a risk of heart disease, blood clots, stroke and psychiatric problems.
