Psychologist Wendy Troxel isn’t surprised to see that men do better when sleeping in a shared bed. Studies have shown that men are very dependent on close relationships — contrary to popular stereotypes, says Troxel, a researcher at the University of Pittsburgh who has studied how the quality of a relationship affects overall health and sleep in men and women.
In general, men show much clearer benefits from committed relationships, Troxel says. “My research shows that married men are much happier and healthier than unmarried men," she adds. “The findings are much less consistent with women.”
