We’ve all heard it: “Don’t go outside without a jacket, or you’ll catch a cold!” But is that actually true? Can cold weather itself make you sick? Let’s break it down.
Colds are caused by viruses, not the weather. The most common culprit is the rhinovirus, which spreads through the air or by touching contaminated surfaces. Whether you’re wearing a coat or not, you won’t get sick unless you’ve been exposed to a virus.
So why do more people seem to get sick in the winter? It’s not because of the cold weather itself, but because of a few factors that come with it. For one, during the colder months, we spend more time indoors in closer proximity to others, which makes it easier for germs to spread. On top of that, winter air tends to be dry, and indoor heating makes it even drier. This can dry out your nasal passages, making it easier for viruses to get in.
It’s also true that being in the cold might put a little extra stress on your immune system, though it alone isn’t enough to make you sick. The increase in colds during colder months is more about these conditions that create the perfect environment for viruses to thrive.
Instead of worrying about the weather, focus on things that actually help. Wash your hands often, avoid touching your face, and stay hydrated. Getting enough sleep is also key to keeping your immune system strong. If someone around you is sick, keep some distance and clean surfaces like phones, doorknobs, and keyboards regularly.
That said, staying warm is still a good idea. While cold weather doesn’t directly cause colds, being too cold can drain your body’s energy, which isn’t ideal if you’re already fighting off germs. Plus, being warm just feels better, right?
So, no, being cold doesn’t give you a cold, viruses do. But it’s still worth bundling up, washing your hands, and taking care of yourself. Stay healthy!
