A Lack of Sleep May Be Turning You into a Cranky, Resentful Girlfriend


The next time you catch yourself snapping at your boyfriend because he forgets to take out the trash, stop and consider how well you dozed last night.

A lack of sleep might be making you resentful or unappreciative toward your significant other, a new University of California at Berkeley study says. Researchers asked 60 couples to keep a journal about their sleep habits as well as be video-taped while they completed problem-solving tasks together.

Those who had a bad night's rest were more "selfish" toward their partners and less likely to say thank you. However the experiment doesn't prove that sleep (or lack thereof) has any effect on attitude, just that the two are related.

"Poor sleep may make us more selfish, as we prioritize our own needs over our partner's," Amie Gordon, a UC Berkeley psychologist and lead investigator of the study, said in a press release.

It can be easy to let a lack of sleep or a bad day get you down, but research shows that taking some time to feel grateful for what you already have can actually improve your health. Even small gestures, such as taking a few minutes before bed to jot down some notes or say aloud a few things about what you're appreciative about, can boost your happiness levels and help you fall into a deep slumber—and a good night's sleep is good news for you and your S.O.
