Night Owls Beware: Late Risers Have Increased Risk Of Early Death

The researchers relied on data from the UK Biobank - a large prospective cohort study conducted between 2006 and 2010 that investigated risk factors for major diseases in men and women 37 to 73 years of age. The study concluded that late risers are at risk of prematurely dying, irrespective of their health conditions.

For the study, researchers from the University of Surrey and Northwestern University examined the link between an individual's natural inclination toward mornings or evenings and their risk of mortality.

Each increase from "morningness" to "eveningness" was associated with an increased risk for disease.

The participants had defined themselves as either "definitely a morning person" (27 percent), "more a morning person than evening person" (35 percent), "more an evening than a morning person" (28 percent), or "definitely an evening person" (9 percent).

Out of the 10,500 deaths recorded in the participants, 2,127 had cardiovascular causes.

"This is a public health issue that can no longer be ignored", Malcolm von Schantz, a professor of chronobiology at the University of Surrey, said in the news release. As part of a detailed questionnaire, they were asked whether they tended to be night owls or morning larks. These night owls also were found to have a higher risk of developing diabetes, and psychological and neurological disorders.

'And we need more research about how we can help evening types cope with the higher effort of keeping their body clock in synchrony with sun time.

Although the reasons for their increased mortality remain unclear, she said, "Night owls should know that there may be some health consequences".

The risk of death was not increased for those who identified as "more a morning person" or "more an evening person" compared with the morning larks, according to the report.


The International Agency for Research on Cancer, an arm of the World Health Organization, says shift work probably causes cancer.

The findings, based on a study of almost half a million participants, showed that night owls suffer from more diseases and disorders than morning larks: They have a 10%higher risk of dying than larks.

Because of that, researchers think that allowing people to have more flexible schedules that fit their internal body clocks could improve their health.

She went on to reveal that "It could be psychological stress, eating at the wrong time for the body, not exercising enough, not sleeping enough, being awake at night by yourself, maybe drug or alcohol use".

Are you a night owl?

The researchers said society needs to recognize that making night owls start work early may not be good for their health.

- Doing things earlier and being less of an evening person as much as you can.

Knutson said that one problem night owls face is living in the morning lark work.
