Duke University scientists find women need more sleep than men

An oldie but goodie: women suffer more from sleep deprivation than men.
I wonder how/if this was an evolutionary advantage.
Women actually need 20 minutes more shut-eye because of the "female multi-tasking brain":
"One of the major functions of sleep is to allow the brain to recover and repair itself," said Professor Jim Horne, director of the Sleep Research Centre at Loughborough University, England.
"During deep sleep, the cortex - the part of the brain responsible for thought, memory, language and so on - disengages from the senses and goes into recovery mode.
"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.
"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."
