Judges in the United States tend to give defendants longer sentences the day after switching to daylight saving time compared with other days of the year, according to research published in Psychological Science, a journal of the Association for Psychological Science.

Previous research has shown that people tend to sacrifice, on average, about 40 minutes of sleep when they "spring forward" to daylight saving time, and even this small amount of lost sleep can have negative consequences, including an increase in workplace injuries, slacking off at work, and auto accidents. The results of this new research suggest that shortened sleep associated with the change to daylight saving time might also affect the severity of sentences doled out by judges.

"We find that the sentences given to those convicted of crimes may be partially polluted by the sleep of those giving the punishments," says researcher Kyoungmin Cho of the University of Washington, first author on the study. "Sleep is a factor that should not play a role in their sentences, but does."
