One study found that, on average, couples suffered 50% more sleep disturbances if they shared a bed.
Sleep specialist Dr Neil Stanley told the British Science Festival how bed sharing can cause rows over snoring and duvet-hogging and robs precious sleep. As such, couples should consider sleeping apart for the good of their health and relationship.
This is not so shocking a proposition as the article went on to report how before the Victorian era it was not uncommon for married couples to sleep apart. In ancient Rome, the marital bed was a place for sexual congress but not for sleeping.
I would suggest that if you partner do not sleep well next to you, either compromise (separate beds on certain days/ night before important meetings etc) or adapt to each other’s sleeping style/ pattern.
