​The cold makes you sick: the truth or a lie?

Every single one of us has been told at one time or another to be careful going outside when it gets cold out. If we don’t stay warm, we’re going to get sick. But is that true?

Is weather a factor?

While yes, it does seem like weather is a factor in whether or not you get sick, it’s not the cold you have to worry about. Going outside with a thin jacket or taking part in a polar bear plunge won’t leave you bedridden the next day. What does affect you is the sudden drop in humidity. When the air gets dryer, the mucus membranes in your nose and lungs also dry out, leaving you more susceptible to illness. Studies have shown, for example, that flu epidemics almost always correspond with a drop in humidity.

How can I keep the air moist?

While you won’t be able to do anything about the air outside, a humidifier can help with the air in your home. Just remember to not leave it running too much, because winter allergies like mold and dust thrive in damp environments.

How is darkness a factor?

Exposure to the sun helps the body produce vitamin D, which helps the immune system fight off disease. But because the sun sets sooner in the winter, the body doesn’t produce as much.

How can I get vitamin D?

Some doctors recommend vitamin D supplements, while others might recommend sun lamps. However, make sure you limit your exposure to these lamps, as they produce more ultraviolet light than the sun, which can burn your skin.

Can winter affect my heart?

Another thing to keep in mind is how the cold weather can affect your heart and blood pressure. Cold weather makes your blood vessels constrict, which makes your heart pump harder to circulate blood. This increases both your heart rate and blood pressure. If you’re doing something physically exerting, like shoveling snow, you have a higher likelihood of experiencing something serious, like a stroke or heart attack.

How can I protect myself?

Make sure to take frequent breaks if you’re physically active outside. If you have a history of blood pressure concerns, take all your medicine as prescribed. Do not take any extra medication without talking to your doctor, and remember to discuss any related concerns with them, too.

What if I do feel like I have a nasal infection?

If you’re sick enough that you need a doctor, make an appointment with your primary care provider or a CEENTA ENT doctor. They can help you get back on your feet and feeling healthy, no matter what the temperature is outside.
