Housework and childcare also play a role, with a “broader context of equality” translating into more restful sleep for women.

“For men, living in a more gender equal context offers a host of benefits with men reporting better health and happiness,” Ruppanner and Raume write. “And, as our study showed, men slept better, too.”

Men don’t get off too easily, though – they also miss sleep, but not generally because of childcare. They’re more likely to lose sleep over work or finances.

“Societies that are more effective in equalising economic and political gender relations have citizens who sleep better,” the researchers concluded. “Since sleep is an integral dimension to health and wellbeing, the economic, health and social benefit to being well-rested cannot be understated.”
