Cold temperatures and changes in weather can't directly make you sick, but they can increase your chances of catching a virus.

What You Need To Know

  • Weather itself can't make you sick but it can create an environment favorable for viruses

  • Dry air can allow virus molecules to travel longer distances

  • People crowding indoors during cold weather can allow viruses to spread more efficiently

We've all heard our mothers say: "Don't go outside without a coat or you'll catch a cold!" But the truth is you can't actually catch a cold from being exposed to cold temperatures. Granted, you should still wear a coat to prevent frostbite and hypothermia. 

It's important to understand that while the weather is not directly responsible for making people sick, the viruses that cause colds spread more easily in lower temperatures, and exposure to cold and dry air might negatively impact the body's immune system. 

Inhaling dry air can decrease mucus production in the sinusus, which is used as the body's natural defense against certain virusus. Breathing in cold air can restrict blood vessels, reducing bloodflow and thus further decreasing the body's defenses. 

The good news is that there are some simple things that can be done this season to reduce your chances of getting sick.

First and foremost, it's important to maintain good hygiene and wash your hands often. Avoid touching your face, as the number one way a virus enters the body is through the mouth and eyes.

Make sure and get plenty of sleep as well since this will recharge the body and the immune system. 

Maintaining a healthy diet and exercise routine is also very important and you can get an extra boost from taking supplements like Vitamins D and C.
