Hogging the sheets appears to be the number one cause of arguments in bedrooms, according to a new study that also found that one in ten adults have considered leaving their partner because disturbed night's sleep had become a big problem in their relationship.
A UK survey revealed that the average couple has 167 bedtime arguments a year that are mostly caused by irritating sleeping habits.
Aside from playing tug of war with the blanket, the second most common reason for night-time arguments is snoring, according to research commissioned by Premier Inn.
The survey revealed that one in ten couples have a bedtime brawls over snoring at least twice a week, and half of the 2,000 adults in a relationship that answered the survey suffered with a snoring spouse with at least 20 percent of the claiming that they lose at least two hours of sleep a night because of it.
More than half of those surveyed said their husband or boyfriend was the snoring culprit, and alarmingly, one in five adults surveyed admitted to waking up once a week because of their own heavy breathing.
Other frustrating bedroom habits were allowing children to sleep in the marital bed, rolling onto the wrong side of the bed, being touched by freezing cold feet during the night and leaving the lights on to read.
"Our research shows that most of the arguments couples have in the bedroom are down to habits that are easy to resolve as a relationship develops," Premier Inn Spokeswoman Claire Haigh said in a statement.
"People suffer from snoring to varying degrees and the research shows how something like snoring can impact on our day to day lives especially if one person in the relationship is missing out on much needed sleep," she concluded.
