Horne is author of the book A Journey through the Science of Sleep, where he exemplifies that one of the major functions of sleep is to let the brain recover and repair itself. And, during deep sleep, the part of the brain responsible for thought memory, language, etc. disengages from the senses and goes into recovery mode.
Additionally, the more you use your brain throughout the day, the more recovery it needs, i.e. the more sleep it requires. Women multi-task a lot so they use their brain more than men do, so their need for sleep is greater.
He goes on to explain that a man with a complex job with a lot of decision-making and thinking may also be in need of more sleep than the average male, though probably still not as much as women.
This is also because the female brain is differently wired than the brain of males. The average is 20 minutes more, although the minutes increase or decrease individually.
How to better your sleep quality
Try some of the following methods and decide which one helps you the most, because, not everyone is the same:
Routine sleep-this helps the brain recognize when it’s time to slow down and relax.
Avoid stimulating foods– avoid consuming caffeine, cacao, chocolate, and sugar shortly before going to bed because these stimulants can cause insomnia.
Meditate-as the brain of women works all the time, some women have problem falling asleep and staying asleep. One way to better your sleep quality is to meditate so that you can relax the brain and prepare it for sleep.
Yoga-yoga prepares the body for a good rest so it is frequently recommended to people who suffer from insomnia.
