Cold Doesn't Cause Colds, But You Should Still Dress Warm This Winter

Have you heard the saying, "put on your coat or you'll catch a cold?" You've likely heard it your whole life and maybe you've even repeated it yourself once or twice.

But did you know there's actually very little evidence suggesting cold weather causes illness?

The common cold is actually caused by a number of viruses that affect the respiratory tract. Most commonly, the common is cold is really a rhinovirus infection, which can also trigger asthma attacks as well as sinus and ear infections.

Why do colds seem more common during colder weather?

There isn't one simple answer.

Viruses, like those that cause the common cold, may find it easier to survive and reproduce in dry, cold air like most experience in the winter.

Additionally, cold weather drives more people indoors, allowing it to spread from person to person more easily.

So, why is it important to dress for the cold?

In extreme cold temperatures, not dressing warm enough can lead to frostbite and even hypothermia.

In relatively normal cold temperatures, it's about keeping your body warm to keep you comfortable and so that your body doesn't drain itself trying to keep your temperature up.

Your body can lose heat through any exposed area, which is why you should try to keep your body mostly covered when you're outside.

Hats or beanies are especially more important for children because they lose more heat through their heads due to it having proportionally more surface area than an adult.

While it isn't necessary to dress in layers, layers give you the ability to adjust the amount of clothing you have on as you go about your day.

What are ways to prevent catching a cold?

While the cold won't give you a cold, there are still measures you should take to prevent getting ill this winter.

1. Make sure you are washing your hands regularly, especially when you return home from public places.
2. Avoid touching your eyes, nose and mouth. Viruses that live on your hands can enter your body through touching your eyes, nose and mouth.
3. Avoid spending time in crowded, indoor public spaces as much as possible. If you are in a crowded public space, consider wearing a mask.
4. Make sure you're up to date on your vaccinations, including your flu vaccine.

While the cold weather might make you want to cozy up in a blanket next to a fire all day, experts also stress the importance of continuing to exercise. Getting regular exercise boosts your immune system and helps you fight off infections. You can check out our workout tips for cold weather.
