Mom Was Right: You’ll Catch a Cold from Being Cold

“Put on a jacket or you’ll catch a cold.”

Countless energetic children are told this every day as they zoom outside for playtime. But as kids grow up, this bit of advice is usually dismissed as an age-old, superstitious epithet. A virus, not the temperature, is what makes us sick, right? Well yes. But it turns out mom’s advice contains a kernel of truth too.

Yale researchers studying the rhinovirus — the common cold virus — have found a link between temperature and our body’s ability to fight a cold. The colder we get, the easier it is for the rhinovirus to trounce us into sniffling, sneezing defeat.

No Wonder It’s Called a Cold

When human rhinoviruses were first cultured way back in the 1960s, researchers noted that the virus replicated more efficiently in temperatures just below core body temperature. Specifically, the virus thrives when temperatures are 91 to 95 degrees Fahrenheit, but slows its replication when temps hit 98.6 degrees.

Roughly one in five people carry the rhinovirus at any given time in the tissues of the nasal passages. The prefix “rhin” in Greek literally means “the nose,” so the common cold is aptly named. Most of the time, our bodies win the fight against the rhinovirus, and sometimes we lose — but why?

The relationship between temperature and rhinoviruses is well established, but the link between our immune response and temperature hasn’t been studied. So, researchers set out to see if, like the rhinovirus, our immune system is also sensitive to changes in our body’s thermostat.

Turn Up The (Cough) Heat

Researchers used a mouse-adapted version of the virus and tested it on cells taken from mouse airways, such as the nose and lungs. They incubated the virus and airway cells at 91 degrees in one batch, and at 98.6 degrees in another batch. To detect the cells’ immune response researchers measured gene activation and chemical signaling within the cells.

They found that the cells stored at 98.6 degrees launched a more robust immune attack than the ones at 91 degrees. The findings, published Tuesday in Proceedings of the National Academy of Sciences, indicate that exposure to cold air might lower our bodies’ ability to fight the common cold. And while most of us can power through a cold, people with respiratory issues or impaired immune systems may have a harder time fighting off the virus.

So heed your parents’ advice and bundle up — you’ll catch a cold if you don’t.

    Somebody should spend money to study whether it’s dangerous to run with scissors or stare at the Sun.

    • garedawg

      Also, save some money to see whether swimming less than 30 minutes after eating lunch will give you a cramp and make you drown.

      • Anechidna

        Been proven that swimming soon after eating doesn’t result in drowning deaths from stomach cramps. Damn another myth bites the dust.

  • Arun

    For quite a while the myth that cold doesn’t help contribute to the common cold was peddled. Good corrective!

    • JDanaH

      “Good corrective!”
      Except that it’s not. This study was on mouse cells, not even whole mice. That’s a far cry from actual humans.

  • Ron Eck

    Research had to be conducted to discern this? I thought this was common sense knowledge among biologists.

  • southside mike

    what’s next? you really get pneumonia if you go out with a wet head?

  • Stephen Davies

    it’s clickbait, baby, clickbait.

  • Christopher Haas

    The caption is still wrong. It’s not being overly technical by arguing that you don;t catch a cold from being cold. Rather, one catches a cold when one is exposed to the virus and when that virus beats one’s immuno-response.

    • Habfan

      Yes but being cold helps the virus defeat one’s immune response, making the caption correct.

      • Seerak

        No virus, no cold, so no it doesn’t. A predisposition is all that chill does, and a predisposition is not the fact.

        • Georce Johnson

          Nope. A cold isn’t the virus in your system, it’s the symptoms of the virus establishing an infection. You could get the virus and fight it off unless you also got chilled, thus the chill could be as much a contributing factor as contacting the virus. As someone who ONLY gets colds when I’ve been cold, I think it’s even more a factor.

    • James Kirk

      Yes, I was hoping to have one on my wife. She and her “logic”….

  • Emily Franklin

    Does this theory contradict entirely the one given years ago that dismissed the idea that cold temperatures causes us to catch a cold because the survivors of Hitler’s holocaust reported very few colds? They reported many contagious diseases but few colds.

    • Seerak

      Not really. On the one hand, it just trivially confirms that our biochemistry works best at 98.6 F, and that’s why our body maintains that temperature so precisely.

      That the rhinovirus takes advantage of cooler cells, such as those in the nose, is also true, but also trivially so – part of that virus’ survival adaptation is being equipped to invade epthelial cells in the nose. Since these tend to be cooler by design, it follows that the virus might not be so good at invading them under unusual circumstances… such as finding the epithelium at core temperature.

    “…researchers noted that the virus replicated more efficiently in temperatures just below core body temperature. Specifically, the virus thrives when temperatures are 91 to 95 degrees Fahrenheit, but slows its replication when temps hit 98.6 degrees.”

    But hypothermia begins when the core body temperature reaches 95º or lower, except how often does that happen?

    • Dave6034

      Rhinoviruses don’t live in the body core, they live in the nose, which is cooler from all the outside air passing through it.

      • Overburdened_Planet

        What an amazingly simple revelation, something that I should have realized when I asked, so thank you for your response.

        • Seerak

          While Dave6034 is correct, this demonstrates the mild sensationalism of the headline.

          It’s the chilling of the epithelial cells in the nose that might make a cold more likely to gain a foothold – the nose lining is normally below core body temperature (that 98.6 figure). If the core itself got to 91 degrees, you’ve got hella bigger problems than a cold.

          • Overburdened_Planet

            Great points!

          • Dustoff Crew Chief

            Yup, like coma and death.

  • KitchenFairy61 .

    I read the paper you mentioned Elena and it ends with this…This is not proof – in any way – that cold weather makes it more likely for you to catch a cold.
    So who is correct? I’ve never believed that getting too cold will make you sick. I have a very vague memory of an article in Discover years ago stating that getting cold has nothing to do with getting sick. In the end it takes about a week from the rhinovirus taking hold to your body’s overactive immune response which is what you’re actually feeling while you are sick. You’ll feel better in a week or so no matter what you do.

  • smartanna

    DUMB & Dumber! Does any anybody w/ an IQ above 75 thinks that a person living in Florida gets as many colds as a person living in Michigan? Holy cow!

    • Zach Winderzight

      Florida gets cold too

  • FrancisChalk

    Just another example of the group think and incompetence of the so-called “medical and scientific” communities. The “medical” experts always said: “catching a cold has nothing to do with the temperature outside.” Usually spoken with a sneer. Yet, everyone else on the planet, who didn’t go to med school, seemed to understand that winter is the cold and flu season for a reason, and not just because we spend more time inside. Now some researcher decides to look at the facts that have been staring them in the face forever, and voila, temperature is a factor. Just remember this and all the other medical/scientific reversals the next time someone from the “science” community starts talking about Climate Change.

    • Seerak

      Just another example of the groupthink of anti-science types – confusing science with its reporting in popular media.

      • FrancisChalk

        Say Doctor Seerak, what do you think about the totally inverted Food Pyramid that the medical/science community is now supporting? They changed the styling of the pyramid so the total 180 on the recommended percentages of carbs vs. protein wouldn’t be so obvious, but none-the-less, it’s a total reversal on the idea of a proper diet. Now just think about this: virtually every doctor’s office in America and 100% of pediatricians and GPs (and the public schools), displayed the old USDA Food Pyramid. The one with pictures of breakfast cereals, loafs of bread, a bowl of white rice, a big bowl of pasta, etc. depicted as the category healthy people should eat most of their daily calories from. For 30+ years virtually every doctor in the country advocated this diet, all the while seeing firsthand the massive increase in obesity of their patients. Didn’t any these doctors learn in med school that carbs are quickly turned into glucose and excess glucose is turned into fat cells? Of course they did, but they mindlessly (as in groupthink) continued to advocate for a diet that is now the direct cause of our number one health/medical problem—obesity and all its offshoots. Yep, those ill-educated “anti-science types” are the problem, for sure!!!

        • http://batman-news.com Ether Doc

          The food pyramid was never based on good science. Yes groupthink is not conducive to sound reasoning. Science is the antidote to groupthink.

  • Mark In FLorida

    Do neither the writer nor the editor(s) know what the word epithet means? Shame.

  • Georce Johnson

    Ready for the NEXT fallacy to implode? Chocolate DOES give you zits. That’s another one wrongly relegated to the “old wive’s tale” status, but I ONLY get zits after a chocolate binge.

    It’s time we started treating scientific decrees with the same suspicion we apply to everything else our fellow flawed humans say.

  • omar

    yah

  • omar

    i also wanna know why do we get sick from flu shots

  • http://batman-news.com Ether Doc

    Interesting but this single in vitro study not done in humans isn’t sufficient to change my mind. Cold humans without contact with other humans don’t catch colds.

  • Pi Threepointonefour

    Oh please. People who are constantly exposed to the cold actually have a stronger immune system, and if your core body temperature is at 91, congratulations, you have hypothermia, and the common cold. If you are 91 degrees, you won’t notice a cold.

    • Dustoff Crew Chief

      I was thinking that myself, “gee, this person is so hypothermic that their brain has ceased to function normally, they’re comatose, and will probably die within the next hour or two, they should really start worrying about catching that cold.”

  • Dustoff Crew Chief

    I question the validity of this study, altogether. It seems the author, and those performing the study, completely ignored the fact that the average temperature of the nose (where the rhinovirus is found) is around 89°F. So, on an average warm day the nose is already below the temperatures this study “supposedly” shows as putting one at risk for a cold (91-95°F).

  • Krys

    So really it’s nothing to do with wrapping up and wearing a coat. It’s actually entirely about the temperature of the air going into your nose?

  • Dustón McCreary

    Totally misleading. Cold air aids the virus, but it is not the virus.

  • Elisebri

    Ok, does anyone realize that 91 degrees is not compatible with life without artificial life support? So obviously, if your body temp drops even down to 95 or 96 degrees, yes, you will definitely become immune compromised. You will not get that cold just playing outside unless you are stranded and become hypothermic. We’re talking core body temp, people!
