It may quash the cuddling time, but couples might want to consider sleeping in separate beds—for the good of their health, sleep experts tell the BBC. Bed sharers suffer 50% more sleep disturbances than those who sleep alone, according to one study. Such lousy slumber can lead to depression, heart disease, strokes, and even divorce. “People actually feel they sleep better when they are with a partner, but the evidence suggests otherwise,” says one sociologist.
One sleep specialist notes that the tradition of bed sharing is relatively new, dating to the industrial revolution when people moved into overcrowded cities and were short on space. “We all know what it’s like to have a cuddle and then say, ‘I’m going to sleep now’ and go to the opposite side of the bed,” he says. “So why not just toddle off down the landing?”
