Proof Daylight Saving Time Is Dumb, Dangerous, and Costly (bloomberg.com) 352

Posted by msmash from the time-to-revisit dept.
From a report on Bloomberg: The case for daylight saving time has been shaky for a while. The biannual time change was originally implemented to save energy. Yet dozens of studies around the world have found that changing the clocks has either minuscule or non-existent effects on energy use. [...] The latest research suggests the time change can be harmful to our health and cost us money. The suffering of the spring time change begins with the loss of an hour of sleep. That might not seem like a big deal, but researchers have found it can be dangerous to mess with sleep schedules. Car accidents, strokes, and heart attacks spike in the days after the March time change. It turns out that judges, sleep deprived by daylight saving, impose harsher sentences. [...] Some of the last defenders of daylight saving time have been a cluster of business groups who assume the change helps stimulate consumer spending. That's not true either, according to recent analysis of 380 million bank and credit-card transactions by the JPMorgan Chase Institute.

      A group of scientists placed five monkeys in a cage, and in the middle, a ladder with bananas on top. Every time a monkey went up the ladder, the scientists soaked the rest of the monkeys with cold water. After a while, every time a monkey would start up the ladder, the others would pull it down and beat it up. After a time, no monkey would dare try climbing the ladder, no matter how great the temptation. The scientists then decided to replace one of the monkeys. The first thing this new monkey did was start to climb the ladder. Immediately, the others pulled him down and beat him up. After several beatings, the new monkey learned never to go up the ladder, even though there was no evident reason not to, aside from the beatinThe second monkey was substituted and the same occurred. The first monkey participated in the beating of the second monkey. A third monkey was changed and the same was repeated. The fourth monkey was changed, resulting in the same, before the fifth was finally replaced as well. What was left was a group of five monkeys that – without ever having received a cold shower – continued to beat up any monkey who attempted to climb the ladder. If it was possible to ask the monkeys why they beat up on all those who attempted to climb the ladder, their most likely answer would be “I don’t know. It’s just how things are done around here.” Does that sound at all familiar?

    • Because your body's circadian rhythm works on a 24 hour clock, simply giving people a day off doesn't fix the problem. If you've traveled internationally, you may have noticed that it's easier to adjust flying West than it is flying East. That's because flying West makes the day longer. You can simply stay up longer each day, and still get enough sleep. But going the other way you have to force yourself awake without enough sleep. It's the lack of sleep which makes it hard to adjust.

      • Speaking of circadian rhythm, nobody considers the fact that DST helps keep it more aligned all year long.

        In modern society, people are pretty much stuck on a fixed schedule all year long due to work, business hours, social events, etc. Having the sun come up at 4:00 a.m. would just serve to interfere with sleep. I would bet good money that the overall health detriment of that all summer long would far outweigh a single hour shift once per year.

    I farm and I'm actually in favor of DST, sort of. The reason is, without DST, during the very long summer days, I would have to wake up at 4 am to do herbicide applications (it's calmest around dawn). With DST I can sleep in until 5am. So I'd much rather have it than not have it. It makes a huge difference. Without DST I would just have to go to bed a lot earlier, but to make that effective I'd have to simply go to bed early all the time to condition my body to wake up earlier. That just doesn't work all that well when everyone else is going to bed later.

    But I would be in favor of simply having DST year round. The reasoning is that without DST, in the winter, folks usually wake up in the dark and drive to work in the dark, and then by the time they head home from work, it's dark again. With DST, you'd still drive to work in the very dark hours, but at least when you got home from work you'd enjoy a short period of daylight. At least for the northern latitudes.
