We aaaaaaaaaaaaaaaall knew this was thing, and now science has officially proved it!
Researchers have discovered that woman DO infact need more sleep than men in order to be productive the next day.
It's a known fact that the more you use your brain, the more sleep you need... aaaaaaaand us girls are the best multi-taskers around!
"For women, poor sleep is strongly associated with high levels of psychological distress and greater feelings of hostility, depression, and anger […] In contrast, these feelings were not associated with the same degree of sleep disruption in men," says Jim Horne, director of Speech Research Centre.
He went on to say: "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."
So basically, even if a dude has a super complex job he still doesn't need as much sleep as a chick because girl's brains are busy being more complex.
