Women Who Sleep More Also Have More Sex, a New Study Finds

Each additional hour of sleep is found to increase the next day's possibility of sex by 14%

Women who get more shut-eye generally have more sex, according to researchers from the University of Michigan, who spent over two weeks tracking the sleep and sexual patterns of 171 young women.

The study discovered that not only did more sleep for women lead to more sex, it often led to better sex. Good sleep hygiene, which refreshes a person’s mood, energy and concentration, is linked to increased sexual desire and arousal. In the study, women reported higher physical arousal after a longer average period of sleep, with the average sleep duration clocking in at seven hours, 22 minutes. More impressively, each additional hour of sleep increased the next day’s possibility of sex by 14%.

“If there’s anything women or their partners can do to help promote good sleep for one another, whether it’s helping out around the house to reduce workload, planning romantic getaways, or just practicing good sleep hygiene, it could help protect against having problems in the bedroom,” the study’s author David Kalmbach told CBS.
