October 2, iStock. They focused on the daily activities of American children, aged 8 to 11, that took place between September 1, and September 15,
One in ten of us is an up-at-dawn, raring-to-go early bird, or lark. About two in ten are owls, who enjoy staying up long past midnight. The rest of us, those in the middle, whom we call hummingbirds, may be ready for action both early and late.
Some hummingbirds are more larkish, and others, more owlish. Animal studies suggest that being a morning person or an evening person may be built into our genes, like having red hair or blue eyes.
This may explain why those of us who are early-to-bed, early-to-rise types, or late-to-bed, late-to-rise types, find it so hard to change our behavior. The Octodon degu, a frisky laboratory rodent whose name comes from its curious back teeth, which resemble the number eight when you look down on them, is helping clarify the role heredity plays in our daily time sense.
Degus are rapidly scampering up the research animal popularity chart because they run around, eat, and socialize in the daytime. This fact appeals to scientists who investigate biological clocks, as they typically work the day shift, too.
Degus love their running wheels, and spend hours working out. Some degus run mainly in the morning, others favor the evening, and the rest show no special preference, Susan Labyak of the University of North Carolina and her colleagues found.
They were the first to document morning and evening traits in the laboratory in day-active rodents, not specially bred for these characteristics. About two in ten were distinct evening types, most active around 9 P. The rest fell somewhere in between.
What Type of Bird Are You? Think of Dagwood Bumstead perennially colliding with the hapless mailman as he races out the door, an act so etched in the public consciousness that it is featured on a U. We are programmed to function best in the daytime.
Night is still the down time on the body clock. Morningness and eveningness are as far apart as humans get. Artist Edward Hopper often portrayed these extremes. In Cape Cod Morning, a woman already dressed for the day gazes out her living room window at trees bathed in dawn light.
In Nighthawks, a man and woman in evening clothes sip coffee in an all-night diner. Lark and owl traits influence many aspects of daily life, including when we feel most alert and when we sleep best. These traits determine when we most enjoy meals, exercise, sex, and other activities.
They also affect when we choose to work, or would, if we could. Emergency room physicians, for example, spend more time working at night throughout their lives than physicians in other specialties. Researchers asked every emergency medicine resident in the U.
Mark Steele and his colleagues at the University of Missouri-Kansas City School of Medicine handed out 2, surveys, and got close to 2, back.
More of the residents tended toward eveningness than is true for the general population. Cartoonist Scott Adams started Dilbert while holding a full-time job, penning it between 5 A.
Since he made it easy for readers to contact him, putting his e-mail address right on the strip, we wrote him inshortly after he left Pacific Bell to work on Dilbert full-time. And I only exercise in late afternoon. I do the strip from 6 A. Then I write for a few hours. I only ink the strip afternoons or evenings when my hand is steady.
We wrote Adams again to see whether his life had changed. So I sleep until 7 A. I do my mindless stuff, like inking or scanning then. Most people say they would like to sleep later, for example.
College students who seldom go to bed before 2 A.
They might complain, but most will manage. By the time they are in their sixties and over, most will be comfortable going to sleep and getting up earlier than they did when younger. All of us might feel and function better, though, if we could synchronize more of our required activities with our natural rhythms throughout our lives.Whether or not you’re a morning person may be encoded in your DNA.
A team of geneticists from the University of Leicester has identified almost 80 genes in flies that seem to be associated with. Sep 24, · Are you a Night Owl, or a Morning Lark?
Today, I talk about the pros and cons of being a life-long Night Owl. Thanks for liking, commenting and subscribing! We would like to show you a description here but the site won’t allow us.
A new study found that night owls—people who like to stay up late—are more likely to die early compared to morning larks, who rise earlier. The new report, published in the journal.
Young children tend to be morning larks, but shift to become night owls after puberty, only to trend back toward a morning preference by later adulthood.
