Night owls live shorter lives than others

A British study published Thursday suggests that the risk of death is 10% higher among people who go to bed late, especially because of the disruption of their internal clock and their lifestyle.

The internal biological clock is a very intelligent part of our body that regulates our body temperature and our sleep cycles over a period of 24 hours. A British study published this Thursday in Chronobiology International argues that the risk of death is 10% higher in people who go to bed late than in those who get up and go to bed early. And this, especially because of the disruption of their internal clock.

The researchers studied the cases of 500,000 people aged 38 to 73, of whom 27% defined themselves as “definitely a morning person”, 35% as “more a morning person than evening person”, 28% as “more an evening than a morning person” and finally, 9% as “definitely an evening person”. In this six-and-a-half year study, 10,500 deaths were reported, of which 2,127 were related to cardiovascular disease.

“Night owls who try to live in a morning world may suffer health consequences,” says study co-author Kristen Knutson, “It’s possible that the night owls have an internal biological clock that does not fit to their external environment “. The specialist mentions a series of bad behaviors such as lack of physical exercise, sleep or eating off the shelf. Late-night babies are also more likely to develop diabetes, neurological, gastrointestinal, respiratory or psychological disorders.

This type of person is also more likely to smoke, drink alcohol, consume caffeine and drugs. In short, their lifestyle combined with the disruption of their internal clock would weaken their body.

Previous studies have pointed to higher rates of cardiovascular disease and metabolic diseases such as diabetes. But this study is the first to explore mortality risk, notes the University of Surrey in a statement.

The study, based on a public database, was published in the journal Chronobiology International.
