Find yourself waking up at night because your spouse is tossing and turning? You might want to consider separate beds.
According to new research from Toronto's Ryerson University, 30 to 40 percent of couples sleep apart at night.
Colleen Carney, director of Ryerson's Sleep and Depression Laboratory, told the CBC, “People will say they sleep better [together], but when we actually monitor their brains we see that their brain is not getting into deeper stages of sleep because they’re continuously being woken up by movement or sound."
Earlier research has confirmed that sleeping in a bed with a partner can be bad for your health. One British study found that couples suffer up to 50 percent more disturbances when sleeping next to someone than sleeping alone.
But don't feel the need to rush out and get separate beds if you're content dozing next to your spouse. As sleep specialist Dr. Neil Stanley said in 2009, "It's about what makes you happy. If you've been sleeping together and you both sleep perfectly well, then don't change, but don't be afraid to do something different."
