A recent survey shows that more couples are sleeping in separate beds, and it’s actually saving relationships.

Sleeping separately is becoming so common that the National Association of Home Builders expects that 60 percent of custom-built homes will include dual master bedrooms in the year 2015.

The National Sleep Foundation conducted a study, and found that 25% of couples in the U.S. sleep separately. A similar survey found one in ten British couples did the same.

Relationship expert. Dr. Tracey Marks advocates separate sleeping, and explained why when speaking to The Heart Beat. “With some couples, one partner is severely sleep deprived because the other partner keeps them awake with snoring, restlessness, keeping the room too hot, etc. If the sleep deprivation makes you cranky, it’s going to affect your relationship and you would be better off sleeping in a different bed so you can be in a better mood with your partner,” Marks said.

Marks added, “While the media presents images of loving couples sleeping contentedly in each other’s arms all night long, for many the reality is much different.”

According to the survey couples fight on average 167 times a year in the bedroom. The number one cause is blanket hogging, followed by snoring, and being too hot.
