Did you know that parents' sleep is reduced to their children's first six years?

British researchers, in collaboration with the German Institute for Economic Research and West Virginia University, have studied the sleep of 459 parents who had a child.

In the first three months after birth, mothers were sleeping on an average less than an hour before pregnancy, while fathers ' length dropped by 15 minutes.

However, when children were between 4 and 6 years of age, the length of sleep was even shorter, 20 minutes with mothers, and 15 minutes with fathers.

“Grate tend to experience more sleep failure than men, after the birth of a child”, this is because “mothers are more often the primary role compared to fathers”, explains Sacari Lemola of Warwick University's Psychological Department.

“While the desire to have children is a major source of joy for most parents, it is possible that many needs and responsible are linked to the role of a shorter sleep and a reduced sleep quality of up to 6 years from the birth of the first child”, he stressed.
