Sleeping in separate rooms (sleep divorce) can improve sleep quality and promote better physical recovery.

The idea of sleeping in separate rooms to optimize rest is based on solid scientific foundations. A survey by the American Academy of Sleep Medicine (AASM, 2023 - observational survey) shows that more than one-third of adults choose to sleep separately to avoid nighttime disturbances caused by their partner. Regarding recovery, research by behavioral scientist Wendy Troxel (observational studies) confirms that sharing a bed objectively increases micro-awakenings due to the other person's movements. However, her work highlights a paradox: couples who sleep together often report better subjective satisfaction with their night due to a sense of emotional security. Choosing to sleep alone is therefore an excellent strategy for personalizing well-being for those with fragile sleep.
