A study of 500,000 people in Britain over six years has found that people who stay up late at night had a 10% greater risk of premature death than early risers.
Kristen Knutson, of Northwestern University in Chicago, and her colleagues found that people who stayed up late had higher rates of diabetes, mental health disorders, and neurological conditions. Night owls were also more likely to experience psychological stress, use drugs or alcohol, and not get enough exercise or sleep.
The report encouraged companies to work with their employees who struggled to make it to work on time, and allow them some flexibility in hours
The authors of the report, released today, encouraged companies to work with their employees who struggled to make it to work on time, and allow them some flexibility in hours to overcome some of the negative health effects.
The problem may be that people who are night owls have a body clock that fails to match their external environment, says Knutson. The report, published in Chronobiology International, also advised night owls to avoid light at night, be disciplined with bed times, and tick off to-do lists early in the day, rather than leaving tasks late into the evening.
