While losing an extra hour of sleep can discourage anyone from seizing the morning, a new survey shows that women may wake up grumpier than men throughout the year.
Duke University polled 2,000 men and women, and according to both genders, women wake up the grumpiest.
Hormones could provide an explanation. Because men and women have different hormone levels, women may require more sleep to keep their hormones in balance.
Researchers say women experienced more depression, anger and hostility early in the mornings when they weren't getting a normal amount of sleep. Researchers added women may require more sleep than men, and they suffer more when they don't get enough.
Lack of sleep can pose health problems for both genders, but in women, risk of heart disease, depression and psychological problems may be more connected to a sleep schedule. Men's health is less connected to sleep, researchers say.
Study: 75 percent of women are sleep deprived
