It’s genes that count

They’re called many things — ”lazy”, ”unproductive”, ”lacking in ambition” — but late risers are starting to fight back. Long the butt of demeaning office jokes, sleepyheads are officially up in arms thanks to a Danish campaign to stop ”the tyranny of early risers”.

”The Owl has the right to say: ‘Give me the late riser’s rhythm at work, at home and in society,”’ trumpets the B-Society website, a movement rallying against the Danish­ 8am to 4pm working culture. ”Let me come to work at 11am and go home at 8pm. Let me have quiet mornings to read my newspaper and ease into the day gently and peacefully.”

It may sound far-fetched, but the B-Society has packed quite a punch in Denmark, attracting about 4 800 members in only four months. Copenhagen city council is preparing jobs for ”chronic late risers” and Carina Christensen, the Danish minister for family affairs, has thrown her weight behind the campaign, saying: ”We all live better­ if our existence is not constantly dictated by an alarm clock.”

”We’ve had tremendous success,” agrees B-Society founder Camilla Kring, who has a PhD in work and life balance. ”We now have a B-high school, with classes starting at noon. Sweden has its own movement, Finland and Norway should soon follow, and there’s been huge global interest.”

According to Kring, an individual’s preference for early rising (an A-person, or lark) and late rising (a B-person, or owl) is as genetically determined as eye or hair colour. And, she says, far from the stereotyping of people who can’t get out of bed in the morning as lazy sods, it’s all down to different circadian rhythms.

”B-people find it easy to stay awake at night, preferring to go to bed at around 1am or 2am, but have difficulty waking in the morning, not feeling fully awake until after 10am,” explains Kring. ”A-people are the opposite — they love the mornings but collapse in front of the TV at about 10pm.”

A convenient excuse to ignore the alarm clock and snuggle under the duvet perhaps, but sleep experts agree Kring has a point. Researchers believe that 10% of people are extreme owls, 10% are extreme larks and the remaining 80% fall in between. And according to experts, it’s genes, not laziness, that count.

Scientists have long known that early and late risers have genetic differences. One study from the University of Surrey found that extreme larks are more likely to have a long version of a gene called Period 3, while extreme owls are more likely to have a shorter version, leading to physiological differences. Professor Angela Clow from the University of Westminster in London, found that early risers had higher levels of cortisol, the body’s main stress hormone, than the alarm-clock refuseniks.

”Personally I think this is better for you,” she says, citing a link between high cortisol levels and greater powers of concentration. ”But because cortisol is a stress hormone, some scientists think early rising puts the body under greater stress.”

A German research team, Dr Peter Axt and Dr Michaela Axt-Gadermann, subscribe to that point of view. In The Joy of Laziness: How to Slow Down and Live Longer, they argue that these higher cortisol levels can damage brain cells and lead to premature senility. Lazy lie-ins, they say, are the key to good health.

Clow’s research showed that over 10 weeks early risers were more likely to suffer from aches, colds and headaches. Meanwhile, a Southampton University study found that those who burned the midnight oil and slept in the following day were no less healthy than the early risers. In fact, they were slightly wealthier.

So why is our work culture biased towards the rhythms of the average lark? Isn’t that all a bit ”sleepist”? Carolyn Schur, author of the night owl’s bible, Birds of a Feather, thinks so. Now self-employed, she spent years in the workplace struggling to cope with early appointments. ”I’ve been called lazy, undisciplined and unprofessional. I was even told I had a psychological problem. I tried to change but just grew more stressed.”

At her clinic in Saskatoon, Canada, Schur treats people with insomnia-related problems who, instead of being actual insomniacs, are what she calls ”desynchronised night owls”, unable to get the sleep they need in a nine-to-five schedule. ”If you’re a night owl who needs nine hours’ sleep, you won’t survive,” she says. — Â
