People who habitually stay up late are more likely to die early, a new study has found, perhaps because their internal body clock is out of sync with a society that favors early risers.
Researchers tracked about 430,000 adults between 38 and 73 years old for 6.5 years. They found that night owls had a 10 percent greater risk of early death than those who prefer to wake up early, Vox.com reports. Those who burned the midnight oil were more likely to have chronic health issues, such as diabetes, neurological disorders, and respiratory disease.
One possible reason, says study author Kristen Knutson, is that the pressure to conform to other people’s work and social schedules leaves late risers anxious, sleep deprived, and feeling as if they live in a perpetual state of jet lag. “There’s a problem for the night owl who’s trying to live in the morning-lark world,” Knutson says.
