Director of the Speech Research Centre at England’s Loughborough University Professor Jim Horne explains: “For women, poor sleep is strongly associated with high levels of psychological distress and greater feelings of hostility, depression, and anger.” He goes on to add that inversely, “These feelings were not associated with the same degree of sleep disruption in men.” Great news, ladies! Science has shown that because the brain of a woman is more complex than the brain of a man, she needs more sleep.
While we now know that the 8-hours-every-night-model is not the ideal template for everybody, most people need to get around 7 hours in order to function like a productive/normal member of society.
Regardless, Professor Horne says women need more sleep than men because their “brains are wired differently from men’s and are more complex, so their sleep need will be slightly greater.” That complexion lays in the fact that women do more multi-tasking than men (“They do lots at once and are flexible”) and use more of their brain more strenuously on any given day, meaning they need more time to recover.
He notes an exception:
“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.”
