The researchers noticed that the risks of premature death are by 10% higher than those who have a normal sleeping pattern.
'We should discuss allowing evening types to start and finish work later, where practical. In order to evaluate natural circadian rhythm, otherwise known as their chronotype, participants were asked to identify as "definitely a morning person", "more a morning person than evening person", "more an evening than a morning person" or "definitely an evening person". For example, some studies have shown that evening people are less likely to eat a healthy diet and more likely to use substances such as alcohol and illegal drugs, compared with morning people. Night owls were almost twice as likely as early risers to have a psychological disorder and 30 percent more likely to have diabetes.
- Doing things earlier and being less of an evening person as much as you can. "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".
"The mismatch between their internal biological clock and their behavior and environment is problematic, especially in the long run", Knutson said.
The researchers said that genetics and environment contribute to a person being a morning or a night person, which means night owls can work their way to becoming morning larks.
"Eating right, exercising, getting enough sleep - all of these things are important, and maybe particularly so for night owls".
Knutson said that "you're not doomed".
"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", Kristen Knutson said.
'They shouldn't be forced to get up for an 8am shift. "Then we'll see if we get improvements in blood pressure and overall health", she said.
"There are already reports of higher incidence of heart attacks following the switch to summer time", says von Schantz. Moreover, people who went to sleep late were two times more likely to develop psychological disorders than the other category.
Research based on 50,000 people in the United Kingdom found they had the higher chance of death over the six-and-a-half year period they were being studied. "I think we need to seriously consider whether the suggested benefits outweigh these risks".
To reach their findings, researchers examined data from 433,268 people who took part in an earlier British study that examined the risk factors for different diseases in people aged 37 to 73.
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" (nine percent).
