Sleeping in separate beds or rooms (a 'sleep divorce') rather than sharing the same bed can help preserve individual rest and improve a couple's quality of life.

Wendy Troxel, a behavioral scientist at the RAND Corporation, shows in her observational work that a partner's nighttime disturbances (movements, staggered schedules) directly harm daytime rapport. Furthermore, a survey by the American Academy of Sleep Medicine (AASM) confirms that one-third of couples occasionally sleep apart to maintain their fitness, with a notable improvement in their rest. Nevertheless, the impact on marital happiness remains highly nuanced depending on the profiles involved. An observational study from 2025 published in the scientific journal BMC Public Health, for example, associated separate bedrooms with lower levels of psychological well-being in some couples. Conversely, sharing a bed promotes emotional closeness and a sense of security that are valuable for romantic balance, provided that each person's rest is preserved. The benefit of sleeping in separate rooms therefore depends entirely on the couple: it is an excellent strategy if one person's nights ruin the other's well-being, but it is not an absolute rule for being happier.
