Late To Bed, Early To Die? Night Owls May Die Sooner (livescience.com)

An anonymous reader shares a report: Bad news for "night owls": Those who tend to stay up late and sleep in well past sunrise are at increased risk of early death, a new study from the United Kingdom suggests. The research, which involved nearly half a million people, found that self-described "evening people" were 10 percent more likely to die over a 6.5-year period, compared with self-described morning people. The findings add to a growing body of research that suggests that being a night owl could have negative effects on health. Many of these effects may be attributable to a misalignment between a person's internal clock, or circadian rhythm, and the socially imposed timing of work and other activities, the researchers said. "'Night owls' trying to live in a 'morning lark' world may have health consequences for their bodies," study co-author Kristen Knutson, an associate professor of neurology at Northwestern University Feinberg School of Medicine, said in a statement.

    I remember a time on the "old" Slashdot when articles like this never hit the front page. Thr article itself seems to give no indication that we are controlling for diet, excercise, other health factors. Just "welp people who are night owls are more likely to die". annecdotally, the times in my life when I was up until 4 AM and sleeping until 2-3 were certainly not the periods where I maintained my health responsibly.

      I couldn't agree more. I think its more likely that people who tend to stay up late and sleep in are associated with more risk taking behavior.

      "Death" is a hell of a test factor for an experiment, especially irrespective of cause.

      That said, i bet if we dug into the data there's way better clickbait titles to be mined in there.
      If someone contracted herpes during the experiment, would sleeping in increase your chances of getting herpes?
      How about buying a new car?
      If you sleep in are you more likely to buy a Ford?

      If i were to completely unscientifically and sight unseen postulate an actual takeaway from a study like this, I would bet that most of these "night owls" work part time or multiple jobs. That is a data point that I would be more interested in.

      You realize that essentially says nothing right?
      Pay attention the the clear effort to avoid making any concrete assertions.

      "Mortality risk in evening types MAY be due to behavioural, psychological, and physiological risk factors, MANY OF WHICH MAY be attributable to chronic misalignment between internal physiological timing and externally imposed timing of work and social activities. These findings suggest the need for researching possible interventions aimed at either modifying circadian rhythms in individuals or at allowing evening types greater working hour flexibility."

      That entire sentence is constructed from the conclusion up, and not from the evidence down.

    The researchers found that the evening people were more likely than the early risers to have poor sleep quality and unhealthy behaviors such as smoking, sedentary lifestyles and eating late at night, Kim said. The night owls also tended to be younger, but were more likely to have high levels of body fat and triglycerides, or fats in their blood, than early risers. (Having high levels of fat is usually associated with older age.)

    I wonder if any of these factors could attribute to a higher mortality rate? This study simply states that night owls have a higher rate of unhealthy lifestyle choices.

    I would be more interested in the mortality rates of night owls who do not exhibit these behaviors. But then again there were only 95 night owls in this study, so I doubt you would be able to determine that from such a small sample size.

    Why is the world designed for "morning larks?" We have telecommuting, electric light, etc -- not all jobs need to be done on 18th century farmers' hours. Is this just the human knack for self flagellation?

      The puritan bullshit thinking. If you're sleeping, you can't be productive and thus you're BAD. And since they're already sleeping again ("after a hard day's work") when you're at peak performance, they don't see you work so you're BAD.

      We have all that now, but a million years or more of evolution have trained our bodies to be more sunlight synchronized. Think of the research stations at the poles where there's a very real concern of depression and it's accompanying conditions without sunlight.

      That said, no judging from here; I've always been a bit of a night owl myself, but not to a great extent. On weeknights I'm usually in bed by 11:30pm and on weekends, I stay up another hour, maybe two, depending. 2am is the latest and that's rare.
      Or maybe it's just more accurate to say I'm definitely not a morning person. I tend to sleep quite soundly at 7am or later, if allowed. Sometimes I even feel drowsier just as the sun starts to come up.

      Why is the world designed for "morning larks?"

      It's not. Movies start at 7:30 or 8, not 6pm. Lots of good TV dramas don't start until 10pm - Heck, Seth Meyers doesn't even come on until 12:35am (to be sure, less of a concern in this era of PVRs). Most restaurants don't even open until 8am on weekends. What breakfast at 6:30am? Unless you want an Egg McMuffin or your have a 24-hour Denny's nearby, ferget it. If your friends invite you out, you're considered a lame weirdo if you need to be home by 11.

    Reminds me of the book, "Eastern Standard Tribe", by Cory Doctorow.

    Since you don't know each others timezones, you might both be waking up at the same time, putting you both in the same tribe.

    The headline is also a lie. It's contradicted in the summary itself. This study isn't about going to bed early or late; it's about how much sleep one gets at night (ie: "Night owls' trying to live in a 'morning lark' world"). If the night owls' simply slept in just as much as they stayed up, it would be an entirely different study.

    Both cocaine and caffeine constrict your blood vessels. It does eventually self-regulate to a more normal state. That's why caffeine withdrawal headaches happen - the body over-dilates the blood vessels in the brain to compensate for caffeine that isn't there.
