A good night's sleep seems to be key to getting along with your partner.

Researchers at the University of Pittsburgh focused on 35 married couples and recorded their sleeping habits.

As you might suspect, they found sleeplessness can lead to irritability and negatively affect the relationship.

But only when the women didn't get enough sleep. No correlation was found when husbands slept poorly.
