If you grew up in a home where the idea of playing in the rain, snow, or cold air would “get you sick,” you’re not alone. This is a common sentiment, but it’s a misconception.

Weather does not cause illness, but things like viruses and bacteria do! This is true across all ages. So, there’s no need to worry about your baby catching a cold purely from being outside on a cold, windy, snowy, or rainy day.

However, it is proportionate to worry about cold weather in terms of appropriate attire. Studies have shown a link between being too cold and a weakened immune response. Meaning, if you do encounter a virus or bacteria, and your body temperature is lowered from being in the cold, too, it can be harder for your body to fight off the germs.

This doesn’t mean you should avoid taking your baby outside on a rainy or cold-weather day; it just means it’s important to bundle up and dress for the weather.

In fact, too much time indoors is often why the cold-weather season is known as respiratory season. When people gather and spend more time in close proximity, germs exchange more readily. If not dressed properly for the weather, this can further leave people susceptible.

Like most things in parenting, there’s a healthy middle ground. Stay warm and dry, wash hands, postpone gatherings if someone is ill, and don’t be afraid to get some fresh, brisk air!
