People are much more likely to lash out at their romantic partners over relationship conflicts after a bad night’s sleep, a new study has claimed.
Researchers from the University of California have found that sleepless nights can worsen lovers’ fights. “Couples who fight more are less happy and less healthy,” said UC Berkeley psychologist Amie Gordon, lead author of the study.
“Our research helps illuminate one factor that leads couples to engage in unnecessary and harmful conflict by showing that couples experience more frequent and severe conflicts after sleepless nights,” she said.
While previous studies indicate that poor sleep has a negative impact on romantic relationships, these new findings shed more light on how bad sleep compromises couples’ ability to avoid and manage conflict, researchers said.
“For the first time, to our knowledge, we can see the process of how the nature, degree, and resolution of conflict are negatively impacted by poor sleep,” said Serena Chen, a professor of psychology at UC Berkeley.
