The Dark Side Of Daylight Saving Time

The Dark Side Of Daylight Saving Time

A train hurtled around a corner at 82 mph, eventually coming off the rails and killing four passengers.

Decades earlier, faulty decision-making resulted in the deaths of the seven-person crew of the Space Shuttle Challenger.

Years before these events, a stuck valve regulating the supply of coolant to a nuclear reactor nearly resulted in the meltdown of a nuclear plant in Pennsylvania. In each of these cases, poor or inadequate sleep was one of the factors that contributed to the failure.

Even if you are not an engineer working in one of those contexts, the odds are pretty good that you occasionally get a poor night’s sleep. In fact, over one-third of American adults sleep less than the suggested minimum seven hours a night and two-thirds of American teens sleep less than their minimum recommended eight hours. Even for those with good sleep hygiene, there is one time of year when you are likely to be short on sleep – the annual shift to daylight saving time.

As an organizational psychologist at the University of Oregon, I have examined a variety of ways in which sleep affects employees. In particular, my colleagues and I investigate how circadian misalignment caused by the shift to daylight saving time leads to costly work and social outcomes.

Even with the extra daylight, the facts don’t look so good

The American public has had a love-hate relationship with daylight saving time since it first became law in 1918. Personal preferences aside, the empirical evidence for the intended benefits of daylight saving time are mixed at best, whereas the costs of the switch to daylight saving time are becoming increasingly evident.

At the crux of these costs is the effect of the time shift on our sleep patterns. When we spring forward, the clocks on the wall advance, but our body clocks do not change so readily. It generally takes a few days for us to adapt to the time change in a way that allows us to fall asleep at our typical time. The upshot is that Americans sleep approximately 40 minutes less than usual on the Sunday to Monday night following the switch.

Along with my colleague, I first examined how the shift to daylight saving time affected workers in blue-collar settings. Using a database of mining injuries from the National Institute of Occupational Safety and Health, we discovered that the spring shift to daylight saving time resulted in a 6 percent increase in mining injuries and a 67 percent increase in workdays lost because of these injuries.

Hazards even if you work above ground

Although these findings might raise some concern, you may have more experience with computers than with mining equipment, and you are probably reading this article at work. It makes sense then to consider how the shift to daylight saving time influences workers in white-collar settings.

We set out to understand these possible effects by examining how people were using their internet access on the day following the time change. By examining internet search patterns over six years in over 200 different American metro areas, we found that searches for entertainment or related categories were much more prevalent (3.1-6.4 percent) on the Monday immediately following the time change than they were on the Mondays before and after the time change. Given that much of this search activity was conducted at work, we concluded that workers are misusing their internet access when they should be working – a behavior called cyberloafing. Such loafing on the job following the time change suggests that people are less productive when mildly sleep deprived due to the time change.

Based solely on the findings from our two studies, along with a study showing that the time change predicts a 5 percent increased incidence of heart attacks, economists estimate that the annual spring time change costs the American economy US$434 million each year. Yet that is not where the costs end.

The time change affects our judgment

Our research has also revealed that the shift to daylight saving time influences our ability to perceive the moral features of a given situation. We again examined internet search behavior and followed up with our own experiment. In the experiment we kept half of our research participants awake throughout the night and allowed the other half to get a full night of sleep. The next day we presented them with scenarios that contained varying levels of moral content.

We found that the day following the shift to daylight saving time, or following a night of sleep deprivation, people were less able to discern when a situation involved issues of moral relevance than when they were well rested.

The time change also affects our judgment in formal settings. A recent study found that judges hand out harsher sentences — 5 percent longer in duration — the Monday following the time change, as compared to other days of the year. This means that sleep and public policy related to sleep could be influencing important decisions that should be impartial.

These studies are only the tip of the iceberg, with adverse consequence of the time change ranging from student test scores to stock market returns.

No matter your sentiment toward daylight saving time, accumulating evidence reveals that the costs of shifting to daylight saving time cut across society. Although the negative outcomes are varied, the singular solution seems quite simple: Rather than change the clocks, we should change public policy. Many state legislatures have taken up this cause, with statehouses coast to coast reconsidering the annual practice.

The ConversationAs the research evidence is considered, other states could end up joining Arizona and Hawaii in abstaining from the annual daylight saving time madness. As we move toward that possibility, we may find it easier to save lives and money rather than chase the daylight.

Editorial Review: Downing is obsessed with Daylight Saving, the loopy idea that became the most persistent political controversy in American history. Spring Forward is his portrait of public policy in the 20th century, a perennially boiling cauldron of unsubstantiated science, profiteering masked as piety, and mysteriously shifting time-zone boundaries.

Editorial Review:
Benjamin Franklin conceived of it. Sir Arthur Conan Doyle endorsed it. Winston Churchill campaigned for it. Kaiser Wilhelm first employed it. Woodrow Wilson and Franklin Roosevelt went to war with it, and more recently the United States fought an energy crisis with it.

For several months every year, for better or worse, daylight savings time affects vast numbers of people throughout the world. And from Ben Franklin's era to today, its story has been an intriguing and sometimes bizarre amalgam of colorful personalities and serious technical issues, purported costs and perceived benefits, conflicts between interest groups and government policy makers. Daylight savings time impacts diverse and unexpected areas, including agricultural practices, street crime, the reporting of sports scores, traffic accidents, the inheritance rights of twins, and voter turnout.

Editorial Review: The transition to Daylight Saving Time (or Daylight Savings Time) happens every year, and yet among all the books of poetry for kids, and there are lots and lots of them, where can one find a fun rhyming children’s book on the topic?

What’s more, where can one find such a book that also teaches a few lessons on manners for children?

The time is ripe for one! And here it is!

In ONCE UPON A DAYLIGHT SAVING TIME, a rattlesnake needs a hand in winding his clock one hour ahead. But there’s a problem. Because he’s used to bossing all the critters around, he’s much too gruff, and each time he meets a potential helping hand, he louses things up with his bad manners. After a long, unsuccessful day, the rattlesnake finds some prairie dogs and rightly sees them as his last hope. Unfortunately, he louses things up once again. However, something’s different this time. Instead of running away, a little prairie dog, shocked at the rattlesnake’s rudeness, decides to teach him the ABCs of minding his p’s and q’s. But with night drawing near, will the rattlesnake learn his lesson in time?

There’s only one way to find out!

However, if you’d like a sample of the story first, read on. For example, here’s how it all begins:


“The day before the wacky change
to Daylight Saving Time,
there happened something sort of strange,
which brought about this rhyme.”



As mentioned above, the rattlesnake has a need. But the problem is that he’s much too rude. Instead of asking politely, he scares the living daylights out of the critters who are his potential helpers:


“Come here! I’ve got a job for you.
Come change my clock right now!
Just wind a part. That’s all you do.
Come here! I’ll show you how.”


Needless to say, the rattlesnake isn’t very successful. Eventually, though, a bright little prairie dog decides to help him, and in doing so, she also helps anyone else who has difficulties with politeness:


“When you need help, don’t yell. Just ask!
And when you ask, say please.
And once your friend has done the task,
say thank you. It’s a breeze!”


And if all the above excerpts still aren’t enough to win you over, how about a final one containing a fun rhyme the book has to help explain the silly time change that takes place when Daylight Saving Time starts:


“1:59 turns into 3.
We leapfrog 2 that morn.
I know it’s odd. Don’t question me.
It’s something many scorn.”


Well, now it’s up to you:
  • Do you want to read a Daylight Saving Time children’s book?
  • Do you want to read one of the most interesting books on manners for kids around?
  • Do you like rhyming stories?
  • Do you want to read one of the most unique books of poetry for children and even adults as well?
  • Do you like rattlesnakes, roadrunners, lizards, and prairie dogs?
If so, then ONCE UPON A DAYLIGHT SAVING TIME is for you!
