According to a (Duke University) survey, women wake up more grumpier than their men.
In fact, females need far more sleep than men and suffer more mentally and physically if forced to go without it.
A lack of sleep can also put them at higher risk of heart disease, depression and psychological problems and in contrast.
Men's health appears to be less dependent on how well they sleep. In fact, men with sleeping problems showed no increased risk of the conditions that were affecting the women.
Is this really true? I'm a total grump in the morning. Maybe that's my feminine side?
