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 diseasenote 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 its 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, which is sometimes Truth in Television, as some people Freeze Sneeze when it's cold, but often these symptoms are treated like a cold.
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. Cold air can also irritate the respiratory tract enough to cause a temporary increase in mucus production, but in that case it's more like having a very mild asthma attack than an actual infection.
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 said mucus.
A common occurrence is when a character takes care to remove their wet clothes if they get soaked in order to prevent sickness, often leading to awkward situations such as Take Off Your Clothes request being misinterpreted or leading to Undressing the Unconscious situation if the character with wet clothes has blacked out. If no other clothes are available they will likely be Hanging Our Clothes to Dry. In a desperate situation they may resort to Intimate Healing.

- 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 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.
- Peanuts: Exaggerated in one strip, where Schroeder claims to have caught a cold from having a chilling sensation listening to music.
- The Haunted House: The Secret of the Ghost Ball: in episode 10 Ian gives Gauen his umbrella after seeing her leave hers over a cat caught in the rain, saying she'll catch a cold if she stays in the rain without one, and telling her the cold doesn't bother him when she protests. Later he's chilled, but never actually gets sick, although it's unclear if it's realism in play or him being immune to the trope because he's a vampire.
- The Bolt Chronicles: When Bolt comes down with a bad cold in "The Mall," Rhino blames it on the dog's jumping into the neighbor's pond to chase ducks on a cold day.
Rhino: [scoldingly] Maybe next time you'll think twice about swimming in the neighbor's duck pond when it's 35 degrees out. It's like when people go outside with wet hair after they take a shower. Not smart.

Laverne has a cold (or possibly flu, nobody's sure) and Shirley thinks that she went into the cold after taking off her coat, but Laverne herself thinks it's a result of being drenched with water after a fight at a party. However, a whole lot of others also got drenched at the same party, including Lenny, who is seen perfectly healthy.

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.
- Beauty and the Beast: Belle's father Maurice lets out a Freeze Sneeze when he first enters the Beast's castle after getting drenched in a rainstorm and develops a nasty cough after the Beast locks him in the cold dungeon. Later, after failing to convince the villagers to help him rescue Belle, he tries to go back to the castle by himself, but gets caught in a blizzard and becomes sicker than ever. Fortunately, when Belle and the Beast see this in the magic mirror, the Beast lets Belle go to take him safely home, where he somehow becomes instantly well enough to ride back to the castle with Belle at the climax.
- In Christmas Carol: The Movie, 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.
- In Peter Pan, Captain Hook is shown sneezing and with a bad headache after the crocodile chases him through the water at Skull Rock.

This is a page-to-screen embellishment, as neither Helen nor Jane is ever punished in that way in the book (although certainly in other ways) and Helen's illness worsens on its own.
- Madeline: Madeline falls into the river and has a sneezing fit, and Miss Clavel seems to think she's sick, putting her to bed with tea and soup. The movie doesn't say if she's actually sick or just chilled, though once she's alone, she gets out of bed and seems fine, although she does almost give herself away with a Sneeze of Doom while trying to hide Genevieve the dog, who followed her home.

- In Babe, Babe catches a cold after running away from home on a rainy night. Though the cold itself concerns the vet less than the little pig's refusal to eat, which unbeknownst to the humans, is because of the reason why he ran away: he just learned that humans eat pigs. But after Farmer Hoggett comforts him with a song and dance, assuring him of his love, he eats again and quickly recovers.
- In It's a Wonderful Life, George lost the hearing in his left ear from a cold he caught as a result of saving his brother from falling in the ice. Zuzu catches a cold from walking home with her coat unbuttoned. George complains that they ought to all have pneumonia from how drafty their house is.

- 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 Sam, Bangs, and Moonshine, Thomas gets laryngitis from nearly drowning.
- Marianne in Sense and Sensibility comes down with a bad fever after moping around a wet garden and not changing into dry clothes.

- At one point in Stuart Little, Stuart is accidentally shut in the fridge and catches a cold which turns into bronchitis.
- In The Tale of Jemima Puddle-Duck, Jemima thinks her eggs will catch cold if she doesn't sit on them. Then again, she is described as a "simpleton".

- Edgar Linton's ultimately fatal lung infection is first triggered by a walk through chilly weather. Soon afterward, Nelly Dean also falls ill for three weeks after walking through cold and dampness while going to and from Wuthering Heights.

- 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.

- A similar game entitled Rapunzel Flu Doctor has Rapunzel and Eugene from Tangled on a date and then Rapunzel falls out of a boat into the lake and catches the flu.
- 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.
- In Katawa Shoujo, Emi catches a cold after staying out in the rain too long.

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 Persona 5, there are five days of flu season. During this time, any enemies you encounter have a chance of starting their battles inflicted with despair, a status effect that disables all actions and kills its victim in three turns. The Reaper is not immune to this. That's right, Death itself can be killed by a cold.

- 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.
- 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.
- An episode of Ben 10 has Ben getting a cold after sneaking into the back of an ice cream truck.
- Defied in the The Berenstain Bears Animated Adaptation of "Get in a Fight" which has Brother and Sister arguing over their treehouse in a rainstorm. Mama orders them to get inside and dry themselves off, then quotes this trope verbatim.
- Betty Boop: In "Betty Boop's Ker-Choo", Betty says that she has a cold "because [she] didn't button up [her] overcoat".

- 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.
- In Madeline's Christmas, the twelve little girls' bedroom window is left open on a snowy night, and the next morning all the girls except Madeline are sick. Chloe is shown sneezing even before this happens, though, and later Miss Clavel gets sick despite being warm in the house. Played more completely straight in the Theatre adaptation, though, where the girls, Miss Clavel and Mrs. Murphy all get sick from going outside without scarves and Madeline is spared because she remembered to wear hers.
- 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 Paper Port episode "Paper Night Fever", Matilda gets a fever, but since she gets a different and random power every day, this fever is actually a super fever (which can burn down all Paper Port if not cured in time), which is later revealed she got it because Charlie was messing with her by changing her bath temperatures too fast to listen to her reactions.
- In Penelope, "Penelope Catches Cold" is an episode where the rain makes Penelope get a cold.
- In the Peppa Pig episode "George Catches a Cold", George's cold is acquired from walking in the rain with no rain hat on.
- The Pororo the Little Penguin episode "Get Well Soon, Loopy" has Loopy catch a very serious cold from getting drenched in water.
- 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.
- In the Rocko's Modern Life episode 'Yarnbenders', Filburt the turtle falls ill after being stuck on his back in the rain, leading Rocko and Heffer having to tell him a twisted fairy tale.
- In the Rugrats episode "Slumber Party", Tommy gets sick when Angelica opens a window in his bedroom before he naps, leading to a Fever Dream Episode where he hallucinates his whole family as figures from the mobile above his crib.
- 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.
- Space Ghost episode "The Iceman". Blip catches a cold after being exposed to prolonged cold temperatures.
- The Spectacular Spider-Man: Peter goes around in un-insulated Spider-Man suit in the dead of snowy winter, and the next time we see Peter Parker, he's sneezing, albeit not nescescarily with a cold.
- On Spongebob Squarepants the Suds are the underwater version of a cold (for sponges, anyway), caught after Spongebob fell asleep in front of an open refrigerator.
- Steven Universe: in "Arcade Mania," Steven wears a loud, puffy jacket to a stealth mission in an ice cave because he "doesn't want to catch a cold."
- We Bare Bears: Notably Averted in "Bear Flu"; though the bears were playing in a lake and fell ill shortly afterwards, it's made explicitly clear that it was because the lakewater was filthy.
- In Winnie the Pooh (2011), the Backson is shown to give Eeyore a cold in the fantasy sequence by sprinkling water on him and blowing icy air at him.
- 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 ice-powered villain Frozer from Miraculous Ladybug has a bright purple nose (he has blue skin, so a red nose would be purple for him) and sounds like he has a stuffy nose when he speaks. His civilian self didn't have a cold when he was akumatized nor does he normally sound stuffed up, so it seems this was done purely because of this trope.
- 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.
- The death of Francis Bacon (stuffed a chicken with snow, died from pneumonia) is a prime contender for this trope. (As usual what really happened is in dispute.)
- Two urban legends surrounding the deaths of US presidents: The throat infection that killed George Washington (or at least that led to his doctors bleeding him to death) is traditionally attributed to a long horseback ride he took through the snow two days earlier, while the pneumonia that killed William Henry Harrison just thirty days into his presidency is usually attributed to the long inaugural speech he gave in cold, wet weather with no coat. In truth, Harrison didn't become sick until three weeks after his inauguration, and the exact cause of Washington's death is still up for debate.
- Similarly, a persistent legend about Emily Brontë holds that she caught a cold at her brother Branwell's funeral, presumably from the harsh autumn weather, which led to her death from tuberculosis three months later. Actually, the accounts from Charlotte Brontë and their household servant Martha Brown imply that she didn't fall ill until a week after the funeral.
- 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. Interestingly, it could clear one's sinuses and or nasal passages, leading to a runny nose
- While the cold doesn't cause illness, it can bring some illness (like the flu or the common cold) out of its incubation period, triggering symptoms, or it can complicate an illness already present (like the Balto and A Christmas Carol examples under Western Animation).
- While it still doesnt make the common cold a deadly disease, there actually really are a few reasons why youre more likely to catch a respiratory virus like those causing the cold or the flu while the weather is cold outside:
- Influenza viruses and coronaviruses (some of which cause the common cold) have been shown to survive much longer on surfaces such as door handles in cool and damp environments, compared to warm and dry circumstances. You can then smear the virus particles onto your mucous membranes if you touch your nose (as humans do unconsciously hundreds of times per day) or eat something without thoroughly washing your hands first.
- As explained above, the cold air can cause the nose to become congested, which then causes people to breathe in through their mouth when doing strenuous activity outdoors. In this case the nose does not fulfill its function of catching virus-laden droplets, aerosols and other particles in the sticky mucus anymore, and so it becomes much more likely that the virus gets directly into your throat or lungs and infects the less well defended tissues there. And of course, you are going to get exposed to these very common and widely circulating viruses, unless you lock yourself up at home and never get close enough to other people to inhale their aerosols.
- Even if you can keep breathing through your nose, when the air is freezing, the body will quickly reduce blood-flow through the capillaries in the nose to avoid losing too much heat. This means that the mucous membranes in the nose get patrolled less frequently by immune system cells and antibodies that travel in the blood, which makes it more likely that viruses that are capable of infecting the type of cells in these membranes (such as rhinoviruses, which also cause the common cold) will have the opportunity to do so before theyre caught and neutralized. Once a few cells are infected, the initial few virus particles get massively multiplied and the more virus particles there are, the higher the likelihood that some are going to survive in the mucus to infect other tissues further down the respiratory tract. (I.e. you first get the sniffles, then a sore throat, then a cough, etc.)
- At the same time, cold winter air dries out once it gets heated indoors (cold winter air carries less moisture than warm summer air), to the point where it can dry out the mucous membranes in your nose, which also makes them less effective at catching viruses before they end up further down the respiratory tract.
- Due to the tilt of the planet and the filtering effects of the atmosphere,note any area on Earth close enough to the poles to have winters with freezing temperatures does not receive enough sunlight of the specific wavelength the human body needs to produce vitamin D in the skin from about September to March. (Also, people spend most of their time indoors in bad weather and are normally bundled up against the cold, so not much sunlight would reach their skin in any case.) The vitamin D that is produced during the summer months is stored in the bodys fat reserves, but there is only so much vitamin D you can produce,note so by the time January/February comes around, most peoples vitamin D storage is running low. Vitamin D is important for a healthy and strong immune system. This is why that time is the main flu season, and why early spring (and not the darkest, coldest time of winter, as youd perhaps expect) is when statistically the most deaths from infectious diseases occur. But its not the coldness of winter thats making you that more susceptible to catching whatever disease is going around. Its the darkness of winter.
- Incidentally, during the COVID-19 pandemic of 2020, it was found in the UK that people with darker skin tones Afro-Brits and South Asians, with a much less pronounced effect for the lighter-skinned East Asians had a much higher likelihood than white Europeans of dying from the disease, which is caused by a type of coronavirus similar to those causing the common cold. Even though everyone in the UK has access to the same health care (the NHS), and even after they controlled the statistics for age, socio-economic statusnote and pre-existing health issues, they found that people with dark skin were still significantly more at risk of severe illness and death if they got infected with COVID-19. The simplest explanation would be that these people have chronic vitamin D insufficiency because their dark skin is evolutionarily adapted to much stronger sunlight and so they cannot produce enough vitamin D even in the summer months and really should take supplements all year round when living in a northern country. Earlier studies also had shown that daily doses of supplemental vitamin D can shorten the length and intensity of a bout of "common cold" (regardless of skin tone, since even white Europeans are low on vitamin D in the winter/spring, as explained above), even if this doesnt significantly reduce the risk of getting infected in the first place. (Large doses taken just occasionally havent been found to result in the same helpful effect, though they can help bring up acutely low vitamin D levels as part of hospital treatment, which is what doctors are actually doing as part of COVID-19 treatment now, since there isnt really any cure for viral diseases and giving vitamins to boost the patients own immune system is a relatively low-risk treatment and vitamins are a already being mass-produced and therefore easily available.)
- In pre-modern times, before the Industrial Revolution and the invention of canning and refrigerators, late winter / early spring was known as the hungry gap in Europe because that was the time when the food harvested in the previous year ran out but nothing much was ready to be harvested yet from the new crops. Especially raw fruit and vegetables couldnt really be stored beyond the time when temperatures got warmer again (or they had simply been used up by that point), and the earliest European berry species only become ripe in May/June. So vitamin C supply, necessary for a strong immune system, was a problem during this time of year. (There were a few stop-gaps, such as Ground Elder, which is a perennial leafy green rich in vitamin C that comes up just a few weeks after the ground thaws - it was imported to the more northerly parts of Europe by the Romans probably for that reason and then was grown by monks throughout the middle ages. Kale was bred to survive even frozen stiff and can be harvested all winter. In the Americas, winter squash was bred to keep for up to 6 months even without cooling. Various peoples around the world invented methods to ferment cabbage or root vegetables, which makes them storable for much longer and also releases/produces more vitamins as part of the microbial activity.note And of course in very northern latitudes, people get their vitamin C more from hunting and eating animals that can synthesize vitamin C internally, unlike our fruit-eating African ape ancestors who lost this ability at some point early in their evolution.)
- While I was listening to a non-English scientific podcast about the COVID-19 pandemic, a virologist specializing on coronaviruses mentioned that the 4 coronaviruses that cause the common cold were originally zoonotic diseases just like the ones causing SARS and COVID-19 and that the last of the 4 harmless coronaviruses jumped from cows to humans in the 19th century.note He said there is a current theory that this now mostly harmless coronavirus caused a quite severe disease epidemic at first as well.note The theory (and hope) is that either coronaviruses in general tend to mutate to become less lethal once theyve entered the human species.note Or else that, once everybody got infected with a specific coronavirus, those that survive have lifelong immunity at least insofar as that they dont get severely ill again because their immune system has learned to notice and fight the virus off.note So, once a new coronavirus has infected more-or-less everybody a least once and is rotating through the population every year like the flu, totally new infections would only occur in children and it seems like coronaviruses (even COVID-19) cause much less severe illness in children than in adults for some unknown reason. So at that point, everyone would get infected with the virus the first time as a child, when it cant hurt you much, and then again and again as adults, but even then you wont get severely ill anymore because your immune system was trained for this specific virus when you were a child. Perhaps that is how new coronaviruses go from deadly pandemic to just another common cold every time one of them jumps the species barrier, even without the virus mutating much. Conversely, if this theory holds true, it would suggest that the coronaviruses that (among other types of viruses) cause the common cold once really were serious and potentially fatal diseases, at least for one generation of humanity, each causing nasty local epidemics whenever it hit a new country/population, similar in severity to what was happening in winter/spring of 2020. (Travel was much slower and rarer in pre-modern times, so it could have taken decades for one specific virus to go around the entire planet.) Which might be part of how the myth of catching your death of cold may have originated.
- While rhinoviruses and the coronaviruses that cause the "common cold" do not cause viral pneumonia (like COVID-19 and influenza viruses can, due to the above-described inflammation overreaction destroying the lung alveoli), it is not at all unlikely that this mild viral infection could keep your immune system busy enough that you get an outbreak of bacterial pneumonia (starting first with bronchitis, i.e. a deep, wet cough) on top of the cold, from bacteria that are already present in and on your body at all times but which are normally kept in check by the immune system, such as Staphylococcus pneumoniae. Or perhaps it is the increased mucus production during a viral "cold" that carries the bacteria from the upper resperatory tract, where they live harmlessly, down into the normally sterile lungs, where the body is not prepared to keep them in check. The exact mechanism how these so-called "commensal" bacteria can suddenly turn on you is still not fully understood, but this bacterial pneumonia then can be fatal, if it's not treated with antibiotics.
