Every March, clocks "spring forward" across much of the United States, robbing people of one precious hour of sleep. (In 2019, Daylight Saving Time will occur March 10.) While hearing those same people complain about being tired is one not-so-surprising effect of Daylight Saving Time, the possibility of a longer prison sentence for those going before a judge on "sleepy Monday" is less expected. Here are 12 surprising effects of Daylight Saving Time—the good, the bad, and the scientifically ambiguous.

1. Increased Spending

In 2016, JP Morgan Chase decided to look into the economic consequences of Daylight Saving Time (DST) by examining Los Angeles and Phoenix, two cities that are large, relatively close to each other, and have stable weather. Critically, Phoenix doesn't observe DST while Los Angeles does [PDF].

Among their findings, DST was "associated with a 0.9 percent increase in daily card spending per capita in Los Angeles at the beginning of DST." Perhaps more surprising, the end of DST was associated with a per capita daily spending reduction of 3.9 percent.

2. A Higher Risk of Heart Attacks

Many studies have shown that DST is associated with an increase in heart attacks, with one study showing a 24 percent increase in the number of heart attacks on the Monday after DST at a group of Michigan hospitals. According to the University of Michigan, Mondays are bad for heart attacks in general (researchers believes the stress of beginning a new workweek and changes to the sleep-wake cycle are the reason why), but DST makes everything worse. Interestingly, the Tuesday following the end of DST was associated with a 21 percent drop in patients.

3. Missed Appointments

Somewhat relatedly, a 2017 study found that the percentage of missed medical appointments increased significantly following DST. But as with heart attack risk, the missed appointments decreased in the fall—at least temporarily.

4. More Car Accidents … Maybe (at Least for a Few Days)

Another field where studies aren't as consistent as one might expect is traffic accidents. In 2001, an American study found that there was a significant increase in accidents on the Monday after the shift to DST. A 2018 New Zealand study echoed the sentiment, finding that on the first day of DST road accidents increased 16 percent. In contrast, a Swedish study found that DST didn't have any important effect in that country.

Of course, there's more to DST than just those first couple days. After DST has gotten started, there's more light on the road later in the day. Several studies have found this light reduces accidents substantially, so much so that one study concluded that a year-round DST would reduce motor vehicle occupant fatalities by 195 per year.

It's so complicated that a 2010 analysis in Minnesota listed 10 studies that found positive effects of DST on road safety, and six studies that showed negative effects in both the spring and fall changes.

5. Longer Prison Sentences

Researchers frequently use DST to study sleep deprivation in populations, as it's a period of time when we all wake up an hour before we’re used to. One of these studies focused specifically on judicial punishment in U.S. federal courts. The researchers looked at "sleepy Monday" (the Monday after the time change) and compared the sentence lengths to other Mondays. They found that on "sleepy Monday," judges handed out 5 percent longer sentences. But don't think you can get a lighter sentence during the fall switch; the researchers found no effect on sentencing at that time. But the researchers point out that this probably isn't limited to judges—even managers may find themselves in the mood for doling out harsher punishments.

6. More Mining Injuries

According to one study of mining injuries from 1983 to 2006, the Monday directly after the switch to DST was associated with 5.7 percent more workplace injuries and 68 percent more workdays lost because of injuries, indicating that there are more injuries that are more severe after the switch [PDF]. There isn't, however, a corresponding decrease in the fall.

7. Fewer Koala Collisions

One study decided to look at how DST affected human-wildlife interaction, specifically koala-vehicle collisions [PDF]. Because koalas are largely nocturnal, they often cross the road in the evening or at night. By shifting traffic patterns to times when it wasn't dark, the researchers found that DST could "decrease collisions with koalas by 8 percent on weekdays and 11 percent at weekends" (although the difference between weekend and weekdays wasn't significant, the researchers proposed that a slight increase in morning collisions lessened the benefit during the weekday). The researchers hope that further study can be done on human-animal interactions and DST.

Koalas aren't the only ones crossing a road that benefit from DST; pedestrians might be safer as well. One study found "no significant detrimental effect on automobile crashes in the short run" and in the long run was associated with "a 8 to 11 percent fall in crashes involving pedestrians … in the weeks after the spring shift to DST." Meanwhile, another study found that a year-long DST would mean 171 fewer pedestrian fatalities a year.

8. Decreased Satisfaction With Life in General (and Increased Use of the Word Tired)

In both the UK and Germany, studies have shown that life satisfaction deteriorates in the first week after the switch to DST in the spring. One study even quantified the deterioration in Germany with money. For the entire sample, the cost was calculated to be €213 (about $262), but for people in full employment—with relatively inflexible schedules—that increases to €332 ($408). And for the men in the sample, the cost of transition was €396 ($487).

Meanwhile, a Facebook analysis looked at the "feelings" people were sharing on the platform. On the Monday after the start of DST, the use of the word tired increased by 25 percent, with similar increases for "sleepy" and "exhausted" (as well as "wonderful" and "great"). In just the period from 5 a.m. to 12 p.m. on Monday, "feeling tired" usage increased an average of 86 percent, from a 12 percent increase in the non-DST Arizona up to a 231 percent increase in Delaware. By Thursday, "tired" is back to normal.

9. Sleepier Kids (Maybe)

The studies surrounding DST and school children are surprisingly inconclusive. On the one side, a 2009 article in Sleep Medicine looked at 469 Germans from 10 to 20 years old and divided them up into 'larks' (those who go to bed early and wake up early) and 'owls' (those who go to bed late and wake up late). They found that after the DST transition the group was sleepier for three weeks after the transition, with owls showing higher daytime sleepiness, and proposed that tests shouldn't take place in the week following the switch over to DST.

A 2017 article in Economics of Education Review, however, looked at 22,000 Europeans students and found that, at least for low-stakes tests, the effect wasn't statistically significant.

10. More Cyberloafing on the Job

Another study looked at people's Google search trends for the Mondays before the switch to DST, immediately after the switch, and a week after, with a specific focus on sites like Facebook, YouTube, and ESPN (i.e. entertainment sites that people probably aren't Googling for their jobs). They found that on the Monday after the switch, people searched for 3.1 percent more entertainment websites than the Monday before DST, and 6.4 percent more than the subsequent Monday. While the researchers caution they can't be sure this was all "cyberloafing," the fact that there was nothing else special about these Mondays meant it very likely was.

11. Mistimed Insulin Shots

It might seem that in this age of smartphones and connected devices that figure it all out, the twice-yearly ritual of finding all the clocks to change is a thing of the past. But that's not necessarily true. In a 2014 article in the Journal of Diabetes Science and Technology, the authors pointed out an easy clock to miss: insulin pumps. Because most commercial pumps aren't GPS-enabled and lack internal time change mechanisms, they have to be manually set up. The study authors discuss an international college student with an insulin pump that came from a country that didn't observe DST, meaning the clock was an hour off. They say that no significant harm resulted, but it just serves as a reminder to make sure you check all your clocks.

12. Higher Energy Bills

One of the main rallying cries for DST is that it saves energy, but studies have been mixed. In 1975 the Department of Transportation issued a report about whether a short-lived, year-long DST experiment had been worthwhile [PDF]. They declared "modest overall benefits might be realized by a shift from the historic six-month DST system," but cautioned that these benefits were difficult to isolate. Optimistically, though, they said DST might help reduce 1 percent of electricity use.

But as modern researchers have noted, electricity usage has shifted since then. Chief among the changes: Only 46 percent of the new single family households completed in 1975 had air conditioning, compared to 93 percent in 2016 [PDF].

Indiana provided a good place to test this change, because in 2006 they decided to observe DST as an entire state (individual counties had observed DST before). A study ultimately concluded that while DST does save electricity in lighting, this is more than offset by increased demands for heating and cooling, resulting in Indiana households being hit by $9 million per year in higher electricity bills [PDF]. However, the study only looked at residential electricity consumption, not commercial or industrial.

Around the same time, the Department of Energy also looked into DST and found that during a four-week extension, electricity use decreased about half a percentage point per day. Ultimately, Stanton Hadley at the Oak Ridge National Laboratory told Live Science, "I could see the answer being either way."

12 Old-Fashioned Insults We Should Bring Back

With the help of social media, slang words and phrases can gain momentum around the globe in what feels like mere minutes. But trendy terms were making splashes long before YouTubers were stanning guyliner-wearing pop stars who slay all day and woke Gen Z-ers were tweeting their hot takes about fake news, mansplaining, and more.

In a new study, digital subscription service Readly analyzed data from its magazine archives to identify some popular terms from years past and present and pinpoint exactly when they stopped appearing in print. Among more positive terms like crinkum-crankum (“elaborate decoration or detail”) and sweetmeat (“item of confectionery or sweet food”) lies a treasure trove of delicious insults that have all but disappeared—and could definitely add some color to your future squabbles.

View Readly’s full timeline of terms here, and read on to find out which insults were our favorites.

1. Loathly

This alternate form of loathsome, meaning “repulsive,” had an impressive run as an insult for nearly 900 centuries, starting in 1099 and not falling out of public favor until 1945.

2. Purblind

According to the Merriam-Webster entry, purblind originally meant “blind” during the 1400s, and later became a way to indicate shortsightedness or lack of insight.

3. Poltroon

The next time you encounter an “utter coward,” you can call them a poltroon. They’re probably too much of a poltroon to ask you what poltroon means.

4. Slugabed

Though this term for “a person who stays in bed late” hasn’t been used much since the early 20th century, it’s the perfect insult for your roommate who perpetually hits the snooze button.

5. Mooncalf

This obscure term for a foolish person also once meant a "fickle, unstable person," according to the Oxford English Dictionary.

6. Fainéant

Fainéant derives from fait-nient, French for “doing nothing.” Its tenure as a popular insult for “an idle or ineffective person” lasted from 1619 to 1670, but the fainéants themselves didn’t disappear with the term—there’s one in practically every group project.

7. Otiose

If you want to pack an extra punch when you accuse someone of being a fainéant, you could also call them otiose, meaning “lazy” or “slothful.”

8. Scaramouch

In Italy’s commedia dell’arte—a type of theatre production with ensemble casts, improvisation, and masks—Scaramouch was a stock character easily identified by his boastful-yet-cowardly manner. Much like scrooge is now synonymous with miser, the word scaramouch was used from the 1600s through the 1800s to describe any boastful coward. Wondering why the obsolete expression sounds so familiar? The band Queen borrowed it for their operatic masterpiece “Bohemian Rhapsody,” though scaramouches aren’t necessarily known for doing the fandango.

9. Quidnunc

From the Latin phrase quid nunc, or “What now?”, a quidnunc is an “inquisitive, bossy person” who’s constantly sniffing around for the next juicy morsel of gossip. Usage dropped off in the early 20th century, but you can always bring it back for that friend who unabashedly reads your text messages over your shoulder.

10. Sciolist

A sciolist is someone “who pretends to be knowledgeable.” Though they might fool a mooncalf or two, any expert would see through their facade.

11. and 12. Rapscallion and Scapegrace

Rapscallion and scapegrace are both wonderful ways to offend a mischievous person—if such a person would even be offended—that overlapped in popularity between the 1700s and the 1900s. While scapegrace refers to an incorrigible character who literally escaped God’s grace, rapscallion is an embellished version of the identically defined (but rather less fun to say) word rascal.

11 Surprising Facts About Sylvester Stallone

Evening Standard/Hulton Archive/Getty Images

As streetwise boxer Rocky Balboa (in eight films) and haunted Vietnam veteran John Rambo (in five films), the man born Michael Sylvester Gardenzio Stallone has made his brand of muscular melodrama a staple of the action film genre across five decades.

The latest Rambo chapter, Rambo: Last Blood, opens September 20. In the meantime, check out some of the more intriguing facts about the actor, from his modest beginnings as an accidental porn star to his peculiar rivalry with Richard Gere to his waylaid plans to run a pudding empire.

1. An errant pair of forceps gave Sylvester Stallone his distinctive look.

Many comedians have paid their bills over the decades by adopting Sylvester Stallone’s distinctive lip droop and guttural baritone voice. The facial feature was the result of some slight mishandling at birth. When Stallone was born on July 6, 1946 in Manhattan, the physician used a pair of forceps to deliver him. The malpractice left his lip, chin, and part of his tongue partially paralyzed due to a severed nerve. Stallone later said his face and awkward demeanor earned him the nickname “Sylvia” and authority figures telling him his brain was “dormant.” Burdened with low self-esteem, Stallone turned to bodybuilding and later performing as a way of breaking through what seemed to be a consensus of low expectations.

2. sylvester Stallone attended college in Switzerland.

Despite a tumultuous adolescence in which he was kicked out of several schools for misbehavior, Stallone eventually graduated high school while living with his mother in Philadelphia. He went on to attend American College, a university in Leysin, Switzerland, where he also worked as a gym teacher and dorm bouncer in addition to selling hamburgers on campus. It was there he became interested in theater—both acting and writing.

Stallone continued his education at the University of Miami before moving to New York with the hopes of breaking into the entertainment industry. While auditioning for parts, Stallone worked as a movie theater usher and cleaned lion cages at the zoo. He was fired from the theater for trying to scalp tickets to a customer. Unknown to Stallone, the customer was the theater owner.

3. Sylvester Stallone’s mother was an expert in “rumpology.”

Stallone’s parents separated while he was still a child. His father, a beauty salon owner named Francesco Stallone, was apparently prone to corporal punishment, and would cuff his young son for misbehavior. (Stallone was once caught swatting flies with a lead pipe on the hood of his father’s brand-new car.) His mother, Jackie Stallone—whom he once described as “half-French, half-Martian"—later grew interested in the study of rumpology, or the study of the buttocks to reveal personality traits and future events.

4. Sylvester Stallone had a small part in a porno.

While struggling to make it as an actor, Stallone was talked into making an appearance in Party at Kitty and Stud’s, a 1970 softcore adult film that was not as explicit as other sex features of the era but still required Stallone to appear in the nude. While he was initially hesitant to take the role, Stallone was sleeping in a bus shelter at the time. He took the $200 for two days of work. Following the success of Rocky in 1976, the film’s producers capitalized on their now-valuable footage and re-released it under the title The Italian Stallion. In 2010, a 35mm negative of the film and all worldwide rights to it were auctioned off on eBay for $412,100.

5. Sylvester Stallone wrote a novel.

In addition to his acting ambitions, Stallone decided to pursue a career in writing. After numerous screenplays, he wrote Paradise Alley, a novel about siblings who get caught up in the circus world of professional wrestling in Hell’s Kitchen. Stallone finished the novel before deciding to turn it into a screenplay. Paradise Alley was eventually produced in 1978. The book, which was perceived as a novelization, was published that same year.

6. Sylvester Stallone was not a fan of the Rambo cartoon series.

After the success of 1982’s First Blood and 1985’s Rambo: First Blood Part II, Stallone was confronted with a litany of Rambo merchandising. Speaking with the Chicago Tribune in 1986, he said he disliked that the psychologically-tortured war veteran was being used to peddle toys. “I couldn’t control it,” he said. “I tried to stop it, but I don’t own the licensing rights.”

On the subject of Rambo: The Force of Freedom, a 1986 animated series featuring a considerably softened-up version of the character, Stallone was resigned. “They’re going to make this Saturday morning TV cartoon show for kids with what they tell me is a softened version of Rambo doing good deeds. First of all, that isn’t Rambo, but more important, they tell me I can’t stop them because it’s not me they’re using. It’s a likeness of a character I played and don’t own.” The show lasted just one season.

7. Sylvester Stallone never planned on the Rocky series enduring as long as it has.

Through the years, Stallone has made some definitive declarations about the Rocky series, which has been extended to eight films including its two spin-off installments, 2015’s Creed and 2018’s Creed II. Speaking with movie critic Roger Ebert in 1979 shortly before the release of Rocky II, Stallone indicated Rocky III that would conclude the series. “There’ll never be a Rocky IV,” he said. "You gotta call it a halt.” In 1985, while filming Rocky IV, Stallone told Interview magazine that he was finished. “Oh, this is it for Rocky,” he said. “Because I don’t know where you go after you battle Russia.” In 1990, following the release of Rocky V, Stallone declared that “There is no Rocky VI. He’s done.” Upon the release of Rocky Balboa in 2006, Stallone once more declared he was finished. "I couldn't top this," he told People. "I would have to wait another 10 years to build up a head of steam, and by that point, come on."

Creed was released nine years later. Following Creed II, he posted a message on Instagram that served as a “final farewell” to the character. Several months later, in July 2019, Stallone told Variety that, “There’s a good chance Rocky may ride again” and explained an idea involving Rocky befriending an immigrant street fighter. It would be the ninth film in the series.

8. Sylvester Stallone was offered the lead role in Beverly Hills Cop.

In one of the more intriguing alternate casting decisions in Hollywood history, Stallone was originally offered the Axel Foley role in 1984’s Beverly Hills Cop. Not wishing to make a comedy, Stallone rewrote the script to focus more on the action, as Detroit cop Foley stampedes through Beverly Hills to find his friend’s killers. Stallone described his version as resembling “the opening scene from Saving Private Ryan on the beaches of Normandy” and said his climax involved a game of chicken between a Lamborghini and an oncoming train. Producers opted to go in another direction. It became one of Eddie Murphy’s biggest hits. Stallone would later use some of his ideas for a rogue cop in the 1986 film Cobra.

9. Sylester Stallone does not get along with Richard Gere.

While filming 1974’s The Lords of Flatbush, in which Stallone and then-unknown actor Richard Gere both played 1950s street toughs, the two actors apparently got off on the wrong foot. Stallone recalled that Gere drew his ire for being too physical during rehearsals—and worse, getting mustard on Stallone during a lunch break. Incensed, Stallone demanded the director choose one of them to stay and one of them to be fired. Gere was let go and replaced by Perry King.

10. Arnold Schwarzenegger once tricked sylvester stallone into starring in a box office bomb.

Stallone has often discussed his rivalry with Arnold Schwarzenegger, as the two action stars were believed to be the two biggest marquee attractions in the 1980s. Recalling his 1992 bomb Stop! Or My Mom Will Shoot, Stallone told a journalist in 2014 that he believed Schwarzenegger was to blame. “I heard Arnold wanted to do that movie and after hearing that, I said I wanted to do it,” he said. “He tricked me. He’s always been clever.”

11. sylvester Stallone wanted to create a pudding empire.

In 2005, shortly before Rocky Balboa resurrected his film career, Stallone embarked on a line of fitness supplements. His company, Instone, produced a pudding snack that was low-carb and high in protein. Stallone even appeared on Larry King to hawk the product. A legal dispute with a food scientist over the rights to the concoction dragged on for years and Instone eventually folded.
