Does Being Cold Make You Sick?

November 9, 2019

Winter is coming – and we’ve all been told to put on a jacket outside, or you’ll catch a cold! Of course, the common response of today has become ‘Don’t be silly, being cold can’t give you a cold’. Or can it? Who wins in this battle of the beliefs? The correlation between cold weather and sickness does stand out. Between 5-20% of Americans catch a cold or flu every year around late fall and winter. Not to mention, it’s called a cold. But there are some important things to consider. First and foremost: colds and the flu are caused by viruses. if there aren’t any around, you won’t catch a cold – no matter how cold you get. It’s as simple as that. So why the correlation with decreasing temperatures? Well for one, people tend to stay indoors much more often during the winter, which in turn, puts them in contact with more people. More people, means more exposure opportunities for the pathogens to spread. On top of this, humidity plays a role in the spread of some viruses. As the humidity decreases in the winter, not only does the virus spread more readily, but the mucus in your nose dries out. Mucus would otherwise act as a protective barrier to pathogens. Finnaly, the lack of Vitamin D which we get from the sun, can affect our immune system adversely. Both being inside more often, and the fact that winter has shorter days makes this a big factor for your health. So you’ve proven your parents wrong… right? Not so fast! While some past studies have shown no correlation to temperature, recent evidence suggest otherwise. One study which put test subjects feet into ice water found that they were, indeed, more likely to develop common cold symptoms in the following days, than those who didn’t. The developing hypothesis behind these results is that the cold temperatures cause blood vessel constriction, which slows the white blood cells from reaching the virus, ultimately inhibiting the immune response. Cortisol levels, which pressures the immune system, are also increased with temperature induced stress. Furthermore, studies on both mice and human airway cells found that immune reaction to the common cold virus, in fact, temperature dependent. Warm infected cells are more likely to undergo programmed cell death, to limit the spread of infection. Finally, studies of the virus itself have revealed a secret weapon of sorts. In winter temperature, the virus’s outer layer or envelope becomes much harder and acts like a shield. This allows it to spread from person to person much more easily. But at warm temperatures, this layer is more of a gel, which is not quite tough enough to protect the virus against the elements. As a result, its spreading ability is compromised. So, maybe your parents weren’t so wrong after all. A happy compromise of going outside more often, bundled up, is likely to get you through the winter unscathed. New to AsapSCIENCE?

    The link between cold feet, decreased blood circulation and immune system less active simply by physical impediment seems to match my personal experience. I remember having associated getting sick with having felt my feet very cold days earlier. However, using scarf around my feet and heating blanket only made my sweat and wet, still getting sick soon after.

    How to avoid a cold (this method has prevented years of colds for me):

    1) Treat colds like allergies and use prevention methods

    2) Leave the house when turning on central heating for the first time of the year. A change in dust, heat and humidity irritate the nasal tissue which cause drainage, drainage causes coughing, coughing and climate change irritates the throat. Put dust filters in your vents to help. Turn on a humidifier and use a barometer to keep humidity around 45-50. Use a space heater instead of central and layer your clothing.

    3) When allergy season is in, cover your mouth and nose with a paper towel when walking from house to car and vice versa (especially if someone is cutting grass). If exposed to grass mold, dust, etc., do a sinus irrigation as soon as possible. Use anti-allergens on bed linens. Vacuum and dust regularly.

    4) Keep hand sanitizer in your car and use it if you have to touch public doors, shopping carts, etc. Don’t touch your face! If someone in public sneezes, go the other way.

    5) A probiotic can boost the immune system. Pro 15 Hyperbiotics is a good one.

    My cousin was adopted from an orphanage in Russia, there they would work to prevent their charges from getting sick by taking them outside in freezing weather and dunking them in cold water. Afterward they would dry off quickly and warm up but this was believed to boost their immune systems and keep them getting sick that winter. She stands by this superstition by taking a really cold shower once a year to this day. Do you think there is anything more to this?

    In countries that have harsh winters for the majority of the year have a habit of going out in the winter in swimsuits. This isn't just done by adults by also enforce in elementary schools. Kids would have an allotted time during the school day to go out and "swim" in the snow. Based on certain research, this has shown to boost their immune response. But how exactly does that happen?

    Hi! Thank you for this video. Would you then say that Pasteur was right with his virus theory? Have you heard of the French scientists Claude Bernard who proved that it is the toxicity of the body that is the cause of illnesses, rather than germs? How can it happen that not everyone in the same space get infected by a virus? Also, aren't all life forms, including germs, more active in summer time? If so, how it comes viruses don't "attack" more in summer? It is due to their outer layer as you explain in the video?

    I would love to read your reply and I am looking forward to it! THANK you in advance! 🙂

    My theory is that cold weather makes some people sick because your body uses more energy to stay warm therefore viruses or bacteria could have that opportunity to attack the body because your body is focusing on staying wrong. Again my theory is this? I am not saying I’m correct but it makes more logical sense than the “ stay home with people “ theory. I just came back from football and I just arrived home and I feel sick because it was cold outside. Now don’t tell me I got ill by coming home because I haven’t even been here more than 5 min
