Scientists found that on average women needed twenty minutes more sleep than men because their brains work harder during the day. The study was carried out on a sample set of 210 middle aged men and women.
“One of the major functions of sleep is to allow the brain to recover and repair itself.”study author Jim Horne told the Mail Online. Prof Horan said the amount of sleep was necessitated by the complexity and intensity of brain activity during the day.
“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. Because of that, their sleep need is greater.”
