British scientists have carried out research of sleep duration, which is necessary for healthy living. They found out that a female organism needs a longer rest than a male.

Nearly 1,000 women and men participated in this experiment. The scientists have noted their impulses of a brain and changes which occur within the nervous system during the day.

It turned out that women are almost always trying to solve several problems simultaneously. The men, on the contrary, are engaged in the decision of issues sequentially, one by one. Moreover, the women employ their both hemispheres of the brain, but the men use only one of them.

It means that the fair sex expends more energy on problem-solving. That’s why, according to the British scientists, the women need to sleep for about an hour longer than the men. Thus, the women will be able to fully restore their strength.
