Daylight Saving Time is hot garbage and it's time to end it

When Benjamin Franklin proposed Daylight Saving Time — he invented it — it was a joke. These days, it's more like a practical joke we play on ourselves every single year. It's time to end this dumb prank once and for all.

Daylight Saving Time wasn't introduced in America until 1918, when it was meant to conserve energy for World War I. The thought was, essentially, Franklin's: that people tend be more active in the evenings, so the extra daylight there would mean fewer hours where people lit their houses at night. After the war, farmers lobbied to get the law repealed; turns out, it's easier to do farm work when the rest of the world is also on the sun's schedule. In 1942, during World War II, DST was enacted again, but year-round. Afterwards, well, adoption varied.

Proponents of DST will tell you that it saves energy. This is because a study in the 1970s found a 1 percent benefit to energy use in Daylight Saving Time. You may notice, though, that the 1970s are now 40 years ago, and energy consumption has changed somewhat in the interim. More recent research shows no difference in energy usage in places where it doesn't go into effect, compared to places observing DST. A few studies suggest Daylight Saving Time actually means more energy is used, rather than less. Take, for example, this 2008 paper that looks at southern Indiana: DST actually increases electricity demand to the tune of $9 million a year in Indiana alone.

And then there's the physiological cost of DST: fatigue. The US Centers for Disease Control and Prevention regard insufficient sleep as a public health problem in general — and the hour you lose in the spring makes it worse. About 60 percent of Americans feel the effects of lost sleep the Monday after they spring forward, according to the Better Sleep Council, the "consumer education" arm of sleep products manufacturers. Almost three-quarters of workers over 30 say the lost sleep affects their work — often by slowing productivity, the survey found. Several major disasters have also been chalked up to sleep deprivation, including the Exxon Valdez oil spill, the Chernobyl nuclear accident, and the explosion of the space shuttle Challenger. Not all of the effects of sleep deprivation are that extreme, but a study in the Journal of Applied Psychology notes that workplace injuries rise on the Monday we spring forward, probably because workers are missing, on average, about 40 minutes of sleep.

People are also likelier to have automobile accidents when they're tired, which is why it's not really surprising to find out that there's a spike in traffic accidents after DST goes into effect. The Monday afterwards, automobile accidents increase, according to a 2001 study in the Journal of Sleep Medicine. Just how much depends on the study; a paper presented at the American Economic Association showed that traffic accidents rise by about 6 percent nationally for the next six days after we move our clocks forward. The spike in crashes is likely due to sleep deprivation.
