(Dr. Robert Glatter, Forbes) Whether you are morning person (lark) or a night owl often becomes a point of discussion among friends, family, or coworkers, since it may reveal important personality traits or characteristics about you.

But belonging to one of these groups now turns out to have important mortality implications, as many have long suspected, but never formally substantiated.

Night owls, according to a new study from Northwestern Medicine and the University of Surrey in the UK, have a higher risk of dying earlier than people who go to bed early and get up as the sun rises.

The study was published online today in the journal, Chronobiology International.

The study, which looked at over 500,000 people, found that night owls have a 10 percent higher chance of dying than morning people (larks).

In the study, this translated to nearly 50,000 people who were at higher risk of death over the 6-year study period.

“Night owls trying to live in a morning lark world may have health consequences for their bodies,” said co-lead author Kristen Knutson, associate professor of neurology at Northwestern University Feinberg School of Medicine in a news release.

For the study, researchers from the University of Surrey and Northwestern University evaluated the relationship between an individual’s preference toward mornings or evenings and their subsequent risk of death.

They polled over 433,000 participants, (aged 38 to 73), asking if they are a “definite morning type” a “moderate morning type” a “moderate evening type” or a “definite evening type.”…Original Source
