Why would that be you ask?
It's simple. It all comes down to the fact that women experience more wear and tear on their body as they juggle doing multiple tasks at once day in and day out.
Scientists say women suffer more than men, both mentally and physically, if they are forced to skimp on their sleep. As well as a higher risk of heart disease, depression and psychological problems, sleep-deprived women have extra clotting factors in their blood, which can lead to a stroke.
In the study, men showed no increased risk of developing the ailments that affect women when they are sleep deprived.
"We found that women had more depression, women had more anger, and women had more hostility early in the morning," said Dr Breus.
One of Britain’s leading authorities on sleep found that women actually need 20 minutes more shut-eye. This is 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."
So men, if your woman wakes up a little grumpier than normal, don't be so hard on her. Rather, help lessen her work load for the day and encourage her to take a nap or to go to sleep earlier than normal.
