Daylight Saving Time Linked To Heart Attacks 240

jones_supa (887896) writes "Switching over to daylight saving time, and hence losing one hour of sleep, raised the risk of having a heart attack the following Monday by 25 percent, compared to other Mondays during the year, according to a new U.S. study released on Saturday. By contrast, heart attack risk fell 21 percent later in the year, on the Tuesday after the clock was returned to standard time, and people got the extra hour of sleep. The not-so-subtle impact of moving the clock forward and backward was seen in a comparison of hospital admissions from a database of non-federal Michigan hospitals. It examined admissions before the start of daylight saving time and the Monday immediately after, for four consecutive years. Researchers cited limitations to the study, noting it was restricted to one state and heart attacks that required artery-opening procedures, such as stents."

    Why not go to bed at the same solar time and wake up at the same solar time? This involves waking up earlier than you need to on work days during standard time. But so what? During daylight savings time, spend an hour in the morning in a cafe drinking coffee and reading a novel.

    Years ago that would mark you as a weirdo because you couldn't stay up and watch some hot TV show that starts at 10PM, but people aren't slaves to the broadcast TV schedule any longer, so why not do things on your own schedule?

    I'm by nature a night owl, but staying up is no big deal for me. Getting up early is a lot more rewarding; everything you like about being up abnormally late is true of being up abnormally early.

    The amount of daylight your body gets ALSO affects your biological health and circadian rhythm.

    If this is what happens once a year, imagine what happens to people who have their schedules changed at random (like a truck driver), or someone on "swing shifts"!

    Little wonder there are so many truckers having heart attacks that end their careers (or even their lives)!

    And to think I worked for a company that the VP actually said to me (with a witness from their own Drivers' Advisory Board present, no less):

    "Circadian rhythm is a luxury we cannot afford in this industry."

    I'd name names, but I might want to return to driving one day, and it could get me Blackballed ;)

    AFAIK, the only reason for this stupid clock change thing is because they don't want children waiting for buses in morning darkness.

    In other news, from what I remember hearing, youth crimes are largely committed between 3PM and 5PM. They get home from school, parents are still at work, and they get into trouble.

    Fix both problems: Stop changing clocks; let kids go to school 1-2 hours later and get home later.

    For one it doesn't work if you're on corporate time. I spent a couple years in a windowless office, and let me tell you winters sucked - I only worked 8-5, but for a couple months near the solstice dawn was just breaking when I left for work, and the sun was setting about the time I left for home. Lunchtime was the only sun I got to see, and that's at at 35.6N latitude, most of the nation is further north and has it even worse.

    These days I am in fact operating mostly on solar time, but daylight savings still meant that 8am went from being an hour or so after sunrise, to having it still hanging on the horizon with only the lit sky providing light. If you presume you need a 30-60 minutes for your morning rituals and getting to work, that means for a few weeks after DST you need to be waking up while it's still dark out, and after you were finally getting to see some sun in the morning too.

    No, not overall economic activity, consumer activity. People go shopping more because daylight is longer. That much is proven, and retailers love DST because of it. Not sure about the overall economic effect. Wouldn't be surprised if it was a net zero.

    So, yes, if you fuck with the clocks like an inconsiderate fucking fucker, I'll lose an hour of sleep.

    Yes, but what you fail to understand is that people have to go to work, and the times of day and night shift over the year. It's not like businesses could just adopt "winter hours" and "summer hours" - everybody must upset their entire day to accommodate it.

    Well, except for Home Depot, Walmart, all the parks, and all those businesses that do have different summer hours. But nobody else could possibly do that - it would be pure anarchy. I mean, children wouldn't even get to go to sleep while it's till light out in June if we did something crazy like keep the clocks the same all year!

    Dozens of lives lost to heart attacks (and the few billion in admin time) is a small price to pay for the soothing hand of Congress regulating our clocks twice a year.
