Researchers from the UK’s University of Hertfordshire conducted a study that measured the relative relationship satisfaction between couples and their sleeping proximity. More than 1,000 people were surveyed for the study.

The researchers found that 55 percent of couples that typically faced each other but did not touch while sleeping were satisfied with their relationship. Of those that slept back-to-back but didn’t touch, 74 percent were satisfied with their relationship and those that slept in the same direction, but didn’t touch, had a 76 percent satisfaction rate. Even better, 94 percent of those that touched while sleeping, regardless of their relative positions, reported being satisfied. The closer the couples slept, the happier their relationships were reported to be.
