The timeless saying “absence makes the heart grow fonder” takes on a new dimension when applied to the realm of sleep. Groundbreaking research from the University of Michigan suggests that couples might reap greater benefits from sleeping apart than sharing a bed, particularly when the pursuit of an uninterrupted eight hours of sleep is the goal.
This revelation aligns with a notable societal shift where couples are increasingly choosing alternative sleeping arrangements, challenging the traditional belief that sharing a bed is a cornerstone of a healthy relationship. High-profile figures like Cameron Diaz have actively advocated for destigmatizing the practice of sleeping in separate rooms.
Referred to as a “sleep divorce,” a recent survey by the American Academy of Sleep Medicine indicates that one in three Americans now favors individual sleeping spaces, citing improvements in both health and relationship well-being. This trend corresponds with the growing number of U.S. citizens reporting inadequate sleep, according to data from the Centers for Disease Control and Prevention.
Dr. Seema Khosla, a pulmonologist and spokesperson for the AASM, underscores the link between poor sleep, mood deterioration, and an increased likelihood of arguments among sleep-deprived couples. She notes, “Getting a good night’s sleep is important for both health and happiness, so it’s no surprise that some couples choose to sleep apart for their overall well-being.”
The University of Michigan study, conducted with mice as subjects, provides fascinating insights into the dynamics of sleep and closeness. The research observed that mice, akin to humans, would sacrifice their preferred sleep locations to be near one another, seeking physical connection and a sense of safety—a phenomenon the researchers termed “somatolonging.” The study authors argue that this concept became especially pronounced during the COVID-19 pandemic when individuals experienced a heightened desire for physical contact.
Whether for mice or humans, it turns out that the act of snuggling may not be as indispensable as commonly believed—especially for those prioritizing a good night’s sleep. As the conversation around sleep divorces gains momentum, the University of Michigan study adds scientific weight to the idea that separate beds may indeed hold the key to not only better sleep but also healthier and more fulfilling relationships.
