Sleeping in separate bedrooms (practicing a "sleep divorce") allows for better sleep and optimal nighttime recovery.

The idea of "sleeping apart" to preserve one's sleep is based on some very interesting scientific observations. A survey by the American Academy of Sleep Medicine (type: observational) reveals that more than one-third of adults sleep separately to protect their sleep. Furthermore, data from the Sleep Foundation (type: survey) indicates that 53% of those who follow this practice report a clear improvement in their sleep, gaining an average of 37 minutes of rest per night. Analyses by the RAND Corporation (type: expert opinion and data review) confirm that our rest rhythms are interdependent and that the presence of the other person can impact our recovery by up to 30%. However, scientific evidence remains based primarily on personal perceptions rather than standardized clinical trials. Additionally, a 2025 study published in BMC Public Health (type: observational) notes that this nightly distance can sometimes be accompanied by a slight decrease in the sense of well-being for some couples. It is therefore an excellent energy optimization strategy if your partner is disrupting your sleep, provided it is adapted with communication.
