When it gets cold outside, our bodies work harder to stay warm. That means less energy for fighting off germs. Plus, we tend to spend more time inside with other people, making it easier for sickness to spread. It’s like your body is saying, 'I’m busy keeping you warm, I’ll take care of the germs later.'
Examples
- You catch a cold after playing outside in the snow without a hat.
- Your brother gets sick after spending all day inside with his friends.
- You feel runny-nosed when walking into a chilly classroom.
