People are more likely to commit suicide after midnight, and the suicide rate peaks between 2am and 3am, according to a new study. Using data from the American Time Use Survey, which calculates the proportion of Americans who are awake at any given hour, as well as the National Violent Death Reporting System, which provides data for time of fatal injury, researchers categorized more than 35,000 suicides by the hour in which they happened, the Fox News reported.

While the weighted, scaled mean suicide rate is 2% between 6am and midnight, it jumps to 10% between midnight and 4am and peaks at 16% between 2am and 3am.

 “This appears to be the first data to suggest that circadian factors may contribute to suicidality, which means, that insomnia is also a risk factor," said the group of investigators Penn Medicine.  Since such a higher percentage of people who are up commit suicide in the wee hours, researchers say that treating insomnia could help lower the risk of suicide, which at 38,000 deaths per year is the 10th highest cause of death in the US, according to Fox News in reference to Medline Plus.
