After adjusting for factors such as sleep duration, body mass index, sex, ethnicity, age, and smoking status, researchers concluded that the risk of dying for those who claimed to be night owls or "definitely evening times" were higher by 10 percent compared to "definitely a morning type".
Night owls run a 10% higher risk of developing health problems such as diabetes, psychological abnormalities and an increased possibility of dying. They asked participants whether they were a morning or evening person, and to what degree (moderate or definite).
The study had a six and a half year follow-up period, and during that time 10,000 people passed away.
Kristen Knutson, associate professor of neurology at Northwestern University Feinberg School of Medicine said: 'Night owls trying to live in a morning lark world may have health consequences for their bodies'.
Knutson suggests, "It could be that people who are up late have an internal biological clock that doesn't match their external environment".
Study co-author Malcolm van Schantz of the University of Surrey, arguing that "night types" should be allowed to start and finish work later in the day, said: "This is a public health issue that can no longer be ignored".
"You're not doomed", added Dr Knutson. A lot of folks identify as night owls.

To measure up a particular stock trading system, it includes a key role of investment market called "Stock Analysis". Closing price generally refers to the last price at which a stock trades during a regular trading session.
When the sun goes down millions of people rev up, becoming energized and productive late into the evening, but burning the midnight oil could mean you'll burn out for good much sooner than early risers.
Knutson plans more research on how night owls can shit their body clocks into sync with larks.
For instance, stress, diet, isolation and drug and alcohol use are all known to contribute to ill-health and may be responsible for the different medical outcomes for morning and evening types.
"Part of it you don't have any control over", she said, "part of it you might". Being a night owl, as noted by the study author, is partly genetic and partly influenced by environmental factors, but it will take a major lifestyle change to become a definitely evening type to a more of an evening type or better yet a morning person.
"If we can recognize these chronotypes are‚ in part‚ genetically determined and not just a character flaw‚ jobs and work hours could have more flexibility for owls‚" she said.
Studies indicate that switches to and from daylight savings time can raise the immediate risk of death over the following days, and others show the health risks of shift work.
They're investigating whether bright light therapy in the morning, or melatonin in the evening, might be able to shift our chronotype, possibly improving health outcomes.
