So please call me, baby Wherever you are It's too cold to be out walking in the streets We do crazy things when we're wounded Everyone's a bit insane I don't want you catching your death of cold Out walking in the rain
The Common Cold is a very mild disease (in first world countries) caused by a number of different viruses that largely have nothing in common other than most of the symptoms they cause. It has been around as long as anyone can remember, but has yet to be stamped out due to the sheer number of "cold" viruses and their different properties. Almost as durable as the disease itself is the myth that it's directly caused by exposure to cold temperatures, and that's what this trope is about.
The origins of the disease's name dates back to ancient times. Long before the advent of germ theory or any understanding of how the body works
, it was believed that one's health was dependent on keeping the body's "humours" - blood, phlegm, yellow bile, and black bile - in balance. The patient exposed to cold temperatures was thought to have taken in a "lump" of cold which would increase the amount of phlegm, so any disease that caused a patient to produce phlegm was said to be caused by "catching cold". In addition, people in pre-industrial times were more likely to embark on travel in the late fall because that's when the year's harvest was sold. Those that went to market (quite possibly through cold, wet conditions) would bring back whatever infections they had been exposed to. Since these infections usually spread through the community in the early winter when the temperature was coincidentally dropping, the common cold gained an additional association with cold weather.
In truth, because the cold can only be caught from other people
, you're far less
likely to catch it if you go wandering through the wilderness on a cold night, although prolonged exposure may well weaken your immune system against an infection already acquired. You'd do far better to worry about the much more severe consequences of real exposure, such as hypothermia and frostbite.
Despite the fact that the actual cause of the cold has been fairly common knowledge for about a hundred years now, this fact has not seemed to permeate the public consciousness very far. (In English-speaking communities, this confusion may just be caused by it's being called a 'cold'.) Mothers still caution their children to button up when going outside lest they catch cold, and any character in fiction, especially animation, will instantly begin to sneeze and cough after being chilled or, especially, frozen
. These symptoms may go away once they've been warmed up again.
There's some legitimacy to this claim, to wit: having a rapid change
in temperature (such as a home with a roaring fire to the freezing midwinter outdoors) can weaken your immune system and make you more susceptible to showing symptoms of the common cold. So, going outside while properly protected from the cold really is good advice for avoiding virus-related unpleasantness, and other cold-related unpleasantness.
The trope, although pretty much a Discredited Trope
at this point, is still used faithfully in fiction and media — exposure to cold means you are going to 'catch' a cold or something worse. Once one has caught cold, if it's a Gross Out Show
, expect rivers of green mucus, horrible shots of runny noses and hankies and tissues dripping with such.
The variations of this trope are rarely combined with Redemption in the Rain
, Snow Means Cold
, or Partly Cloudy with a Chance of Death

Anime and Manga
- Kiki's Delivery Service: Kiki ends up sick in bed after getting caught in a storm doing a delivery.
- In Hidamari Sketch, when Yoshinoya-sensei (and a number of students) is out sick, the principal advices the other students to take care of themselves, specifically warning them not to go out with wet hair on a cold day just because "you think it looks cool" (implying that that's how Yoshinoya-sensei got sick).
- In the Pokémon anime episode "The Ice Cave!", Team Rocket doused Ash and his friends with cold water inside the title icy cave, causing Brock to come down with symptoms similar to influenza.
- In the first movie to Cardcaptor Sakura, Sakura falls into a (shallow) well and gets completely soaked and then sneezes.
- In A Cruel God Reigns, Jeremy immediately catches a cold after he attempts to throw himself in the lake during a freezing rain but is pulled out by Ian. The trope is lampshaded by Lindon, who says he's more worried about Jeremy catching a cold than he is about water in his lungs or the possibility of an irregular heartbeat. To be fair though, Lindon states that Jeremy is probably also sleep deprived, and that the exposure to the cold may have just been the final blow to his immune system.
- In a Filler episode of Fairy Tail, Lucy catches a cold after being buried in snow while other guild members battle a wyvern.
- In Free! Haru catches a cold from swimming in the newly restored Iwatobi High swimming pool too early in the season.
- In the first series of Jewelpet, Dian has a cold that lasts for several episodes after his release from his frozen seal.
- If Thems The Rules, Tom ends up sick after other kid dumps a bucket of ice water on "accident" in the middle of winter.
- The Stalking Zuko Series Zuko gets extremely sick from cooler fever as warming himself in a freezer caused a temperature shift that weakened his immune system.
- In Fever Dreams Light and L get sick after staying out on the roof in the rain and having sex for a prolonged period of time.
- In Travels of the Trifecta, Paul catches a severe cold from being soaking wet in the rain near the beginning of the story.
- In Kill la Kill AU, in Snowflakes, when an already ill Ryuuko escapes the hospital, this was subtly brought up as a concern, however, it is mostly because the cold may already worsen her illness (the which she was in the hospital for) or that she could freeze to death.
- In the picture book Mr. Putter and Tabby Catch the Cold, Mr. Putter catches a cold after he goes outside in the snow without his hat.
- In the Greyfriars stories, anyone who gets soaked with water is liable to be coughing and sneezing by the following chapter.
- In Samantha's birthday story in the American Girl series, Samantha complains that her grandmother makes her wear long underwear from September to June to prevent consumption.
- The titular character of Ishmael "dies" of pneumonia after being out in the cold too long.
- In the Belgariad, cave-dweller Relg catches a cold soon after emerging onto the surface world for the first time; although exposure to the other characters might have infected him with something to which they were already immune, the text implies he caught it from the unaccustomed weather. (Then subverted: Relg recovers by walking through rock.) In the Malloreon, one character voices an apparently serious concern that the Team Pet snake might have caught a cold, though this proves not to be the case.
- In the final book of the The Dark Tower series, Roland starts coughing and seems to have the start of pneumonia due to the extended exposure to cold and long amounts of walking with minimal nutrition. He eats a part of a freshly killed deer to cure it.
- Bilbo in The Hobbit catches a cold after his ride downriver on a barrel, soaked through and very cold when he arrives.
- In Pride and Prejudice, Jane ends up with a bad cold after riding her horse through the rain to see Mr Bingley.
- Similarly, Marianne in Sense and Sensibility comes down with a bad fever after moping around a wet garden and not changing into dry clothes. This is more justified because she'd been generally neglecting her health and contemporary medical treatment included bloodletting, which would just makes things worse (not that Austen knew it at the time).
Live Action TV
- In F Troop, it happens to Captain Parmenter after he keeps getting water dumped on him in one episode. Unfortunately, the cure leaves him Unsuspectingly Soused.
- Invoked in Highlander...Anne tells Duncan he'll get a cold from sitting out in the cold air. (And she was a doctor. Eesh. as for whether immortals get sick,we never find out for sure.)
- From Christina Perri's "Jar of Hearts": "You're gonna catch a cold/From the ice inside your soul". Todd in the Shadows sums up this insult perfectly.
- In a Calvin and Hobbes strip, Calvin deliberately catches a cold (to escape schoolwork) by opening the window and putting his head outside. In another strip, his mom refuses to allow him to play in the rain because he might catch pneumonia, although this is somewhat more justified as pneumonia can be contracted from spores or molds.
- An old British folksong "On Ilkley Moor" suggests that, from traveling on Ilkley Moor without a hat ("baht'aht"), then "thou'll catch thy de'ath of cauld!", after which there are other repercussions, leading to a somewhat cannibalistic observation!
- The Earthdawn supplement Earthdawn Survival Guide had a game mechanic for catching a cold after being caught in the rain.
- In Harvest Moon: Animal Parade, if you work too hard in the rain, you'll catch a cold. The cold makes it so it takes more stamina to do work, unless you cure it. You also lose stamina faster just by working in the rain itself, but that's a somewhat more reasonable assumption to make, because doing hard work while soaking wet, in high winds, seems more difficult.
- Almost happens to Dr. Wily in Mega Man 10.
- Phoenix himself in Phoenix Wright: Ace Attorney: Trials and Tribulations catches a cold after falling to a river in a very cold mountain. While the fall only caused him minor injuries, the sudden shift in temperature caused his immune system to weaken.
- Snake gets a cold after being stripped of his suit in Metal Gear Solid, although it only serves as something to attract guards.
- He gets a cold again in the sequel, after sneaking around in the pouring rain.
- In Persona 3, the main character gets caught in the rain on the way back from school during the onset of a typhoon, and spends a few days in bed with a fever. The main character can also come down with a cold if fatigued by studying too late or spending too much time dungeon-crawling in Tartarus; because daytime is being spent in a crowded school and the fatigue weakens his immune system, this is in fact more realistic than catching cold due to the weather.
- In Ocarina of Time, Idle Animation changes based on your environment. If it's a cold place, you shiver, and then sneeze.
- In Katawa Shoujo, Emi catches a cold after staying out in the rain too long.
- In Mario & Luigi: Bowser's Inside Story, the late-game boss Blizzard Midbus attacks using snow and ice-based powers which can cause Bowser to become sick.
- Avatar: The Last Airbender: After getting caught in "The Storm", Katara and Sokka both come down with severe colds. Aang, who is of stronger constitution (possibly due to having spent a century as a Human Popsicle), remains healthy and has to undertake the Fetch Quest to get their cure. They're an inversion because they're from a frozen climate but were not acclimated to a warmer climate.
- On Spongebob Squarepants the Suds are the underwater version of a cold, caught after Spongebob fell asleep in front of an open refrigerator.
- Inversion: The Year Without a Santa Claus: Vixen, who's acclimated to the frigid temps of the North Pole gets sick when she goes to warm weather Southtown.
- The Spectacular Spider-Man: Peter goes around in un-insulated Spidey suit in the dead of snowy winter, and the next time we see Peter Parker, he's sneezing.
- Batman: The Animated Series: Fighting Mr. Freeze is enough to give Bruce a cold. Justified: it's stated there's an exceptional heat wave occurring; the temperature shift would weaken his immune system.
- In one Looney Tunes short, a dog trying to find shelter from the snow trespasses into a skunk's house. The skunk runs him out and he falls into a frozen pond, catching a cold in the process... which works to his advantage, as his nose is now too stuffed up to be affected by the skunk's odious smell.
- Space Ghost episode "The Iceman". Blip catches a cold after being exposed to prolonged cold temperatures.
- In an episode of The Magic School Bus, when Arnold takes his helmet off on Pluto, his head freezes over. Back on Earth, he's just got a cold. Just so everyone's clear, the estimated warmest temperature on the surface of this little ball of ice is just about a skip above absolute zero.
- In the movie Balto, Rosy is taken to the doctor, and sees her dog Jenna outside. When Rosy goes to play with Jenna, she starts to cough, and her father rushes out saying, "You'll catch your death out here!" Justified, as Rosy was already sick with diphtheria, and being outside on a cold Alaskan winter evening with no coat would have likely made her worse.
- On the Futurama episode "Cold Warriors", Fry gets a cold as a child when he falls into freezing water while ice fishing. It happens again in the year 3010, a time where the common cold has been eradicated, and Fry's dormant strain threatens to contaminate the whole world.
- In Winnie-the-Pooh, the Backson is shown to give Eeyore a cold by sprinkling water on him and blowing icy air at him.
- My Little Pony: Friendship Is Magic: In "Winter Wrap Up", Spike has fallen asleep on the last piece of ice left in the lake. Applejack jokes he's in for a big surprise when it finally melts. Next time we see him, he's wrapped in a blankie by the fire with fuzzy slippers, looking sick.
- In an episode of The Simpsons, Homer makes Lisa crawl into a freezer to get a particular tub of ice cream, and she comes down with a cold. She then spends all her time playing a parody of Crash Bandicoot, and cheats on an English test.
- A possibly justified example is found in one animated version of A Christmas Carol: Tiny Tim, only just recovering from pneumonia, makes the mistake of caroling outside Scrooge's window, and Scrooge throws a bucket of cold water onto him. This triggers a relapse of his illness, which is what would have killed him if not for Scrooge's ghostly adventures that night.
- Played ridiculously straight at the end of the Recess episode "Rainy Days." Less than a minute of playing outside in the rain has T.J. and friends all sneezing and feeling sick by the time they go in.
- During his visit to the Western Isles of Scotland in 1773, Samuel Johnson was told that everyone on a certain island normally caught colds shortly after the quarterly ferry boat arrived. He thought the story unlikely, since the contemporary understanding was that the common cold was caused by exposure to cold, but nevertheless reported the conversation faithfully in his book about the trip. The story was eventually referenced as evidence to support the germ theory of disease.
- Prolonged exposure to cold does sometimes bring on a temporary bout of the sniffles, as breathing cold air slows the action of cilia that normally keep the mucus coating of the nasal passages from accumulating. Such environment-induced nasal congestion isn't infectious, however, and clears up quickly once the sniffler resumes breathing normal-temperature air.
