Decoding why females get less sleep

Study suggests biological factors may play role in why women sleep less, wake up more often

While caregiving roles often take a toll on women's sleep, a new study on Thursday suggested that biological factors may also play a role in why females sleep less.

The study, published in the journal Scientific Reports, showed that women sleep less, and wake up more often. They also get less restorative sleep than men. The findings based on experiments in mice shed new light on what may underlie sleep differences in men and women.
