Does Cold Weather Really Make You Sick?

It’s seems like every year I get into a conversation about seasonal illnesses that crop up this time of year. My mom used to say things like “you’ll catch your death out in that cold” and “bundle up so you don’t get sick.” Are these just wives tales or is there something to it?

I recently had a conversation with my sister, who is a nurse. She is adamant that being in the cold does not make you sick. She cites science to back up her claim. So why then has it been passed down as common wisdom through mothers that the cold will make you sick?

Inquiring minds sent me to Google. So here’s what I found out…

The cold itself doesn’t make you sick. However, it can create conditions that make it easier for you to catch a cold or the flu. Here’s how it works:

  • Lowered Immunity: Cold temperatures can lower the immune response in your nasal passages, making it easier for viruses to take hold.
  • Indoor Gatherings: When it’s cold, people tend to stay indoors more, which increases the chances of viruses spreading from person to person.
  • Dry Air: Both indoor heating and cold outdoor air can dry out you nasal passages, reducing their ability to trap and expel viruses.

The cold weather itself isn’t the direct cause of illness. However, it can contribute to conditions that make it easier for you to get sick. So… mom was essentially right. Stay warm, keep your immune system strong, and practice good hygiene to help fend off those winter bugs!
