Sleep in separate bedrooms (a practice sometimes called a "sleep divorce") to eliminate nocturnal disturbances from one's partner and obtain more restorative sleep.

This approach is based on solid yet conflicting scientific foundations. On one hand, a survey by the Sleep Foundation (observational data) reveals that more than 52% of people who sleep separately report a clear improvement in their sleep, with an average gain of 37 minutes of rest per night. Researcher Wendy Troxel (expert opinion) further notes that nearly 30% of the quality of our nights is directly influenced by a partner's noises or movements. However, intimacy also has its secrets: a study led by Henning Drews in 2020 (laboratory measurements via polysomnography) demonstrates that sleeping as a couple increases REM sleep by 10% and makes it more stable. Choosing separate beds is therefore ideal for avoiding physical awakenings, even if sharing a bed naturally optimizes the biological architecture of our nights.
