Bad news, night people: If you routinely stay up late, you may be more likely to die, get diabetes, or develop a psychological illness.
A study published in the journal Chronobiology International found that people who identify as “definite evening types” are more susceptible to several health problems, including diabetes, neurological disorders, psychological illness, and a higher risk of mortality than those who identify as “definite morning types.”
Researchers tracked 433,268 adults in the United Kingdom over an average of six-and-a-half years. The participants were asked to put themselves into one of four categories: “definitely a morning person”; “more a morning person than evening person”; “more an evening than a morning person”; or “definitely an evening person.” Over the course of the study, just over 10,000 participants died, and researchers found that those who identified as “definite evening types” were 10 percent more likely to die than their sunrise-loving counterparts.
“Previous work has shown that people who are evening types — are night owls — tend to have worse health profiles, including things like diabetes and heart disease,” Kristen Knutson, associate professor of neurology at Northwestern’s Feinberg School of Medicine and one of the authors of the study, said in a press release, “But this is really the first study to look at mortality.”
