The nocturnal "night owls" they run more risk of dying than the "skylarks" that get up early and jump out of bed when the sun rises, new research has shown.

Night owls stay up late but struggle to get out of bed in the morning.

Scientists who studied a population of almost half a million Britons discovered that during a period of six years, owls had a 10% higher risk of lark death.

The difference remained even after adjusting for expected health problems in owls, such as metabolic dysfunction and heart disease.

Society should awaken to the real difficulties faced by night owls, the researchers said. They called on employers to be more flexible with staff who suffer when they are required to register early.

Dr. Kristen Knutson, team member at Northwestern University in Chicago, USA. UU., He said: "Night owls trying to live in a morning The world of the lark can have consequences on the health of their bodies.

" They should not be forced to get up for an 8 am shift. Make the work shifts match the chronotypes of the people. Some people can better adapt to night shifts. "

This is a public health problem that can no longer be ignored. Professor Malcolm von Schantz

The study, published in the journal Chronobiology International, found higher rates of diabetes, Mental disorders disorders and neurological conditions among nocturnal owls.

Researchers turned to data from the UK Biobank, a store of medical and genetic information provided by 500,000 people ages 40 to 69 from across the UK.

Co-author British Professor Malcolm von Schantz, of the University of Surrey, said: "This is a public health problem that can no longer be ignored.

"We should discuss allowing evening types to start and finish work later, when practical, and we need more research on how we can help nightly types cope with the greater effort of keeping their body clock on synchrony with solar time ".

Larks can better adjust their body clocks to the rhythms of light and dark and sunset, the researchers said.

Owls may have a biological clock that does not match their external environment, said Dr. Knutson.

Being a nocturnal bird was associated with psychological stress, eating at the wrong time, lack of exercise, lack of sleep and use of drugs or alcohol.

Genetics and the environment played roughly equal roles to determine whether you are a person at night or in the morning, the scientists said.

One way that night owls could help themselves was to make sure they are exposed to light early in the morning, but not at night, according to Dr. Knutson. They should try to be disciplined about sleeping hours and doing work early in the day, rather than leaving them late, he said.

Dr. Knutson added: "You are not condemned, part of it has no control, and part of it is possible"
