A study has suggested that women need more sleep than men because the female brain works harder during the day.
Scientists suggest that women need around 20 minutes more sleep per night than men, and this is all down to their multi-tasking brain.
“One of the major functions of sleep is to allow the brain to recover and repair itself,” Professor Jim Horne, director of the Sleep Research Centre, told the Mail Online.
“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.”
However, men that do a job that requires a lot of complex decision makering, do require more sleep than a man who doesn't have as much of a demanding job.
Obviously this isn't an exact science, and Home admits "Individual needs differ greatly - some people can get by easily on six hours while others can't. What is important is that people have enough sleep to ensure they do not feel excessively sleepy in the day.”
