Bed Sharing Often Improves Sleep
- Sharing a bed with an adult partner tends to improve sleep quality and mental health in working-age adults.
- The University of Arizona found faster sleep onset, fewer night wakings, and lower depression and stress risks.
Who You Share With Matters
- The benefit depends on who you share with: sleeping next to a child or family member can reduce sleep quality.
- A 2020 Kiel University study found couples got up to 10% more REM sleep than solitary sleepers.
Consider Practical Sleep Arrangements
- If your partner snores or has different routines, consider sleeping separately to protect sleep quality.
- Practical 'sleep divorce' arrangements can be temporary and many couples reunite in bed later.
