Couples argue at least 167 times a year, reveals study.
One in 10 couples in Britain has a night-time fight at least twice a week over their partner's "sound effects" while sleeping, said the study by Premier Inn, one of the biggest hotel brands in Britain.
More than 20 percent lose two hours sleep every night because of noise. Ten percent said they were even considering splitting up because of it, the Daily Express reported.
One-fifth of men admitted they woke themselves up with their own heavy breathing.
Other reasons for fights include being too hot or too cold and a lack of passion on the bed.
"Most of the arguments couples have in the bedroom are down to habits that are easy to resolve as a relationship develops," said Claire Haigh of Premier Inn.
