 Couples are more likely to sleep in sync when the wife is satisfied with the marriage, a new U.S. study shows.

Researchers at the University of Pittsburgh had 46 couples complete relationship assessments and gathered sleep data over a 10-day period.

They found when the wives reported higher marital satisfaction, the percentage of time the couple was awake or asleep at the same time was greater.

"The sleep of married couples is more in sync on a minute-by-minute basis than the sleep of random individuals," the study's lead author Heather Gunn said in a release Thursday. "This suggests that our sleep patterns are regulated not only by when we sleep, but also by with whom we sleep."

The study was presented Wednesday at the annual meeting of the Associated Professional Sleep Societies LLC in Minnesota.
