Imagine your body is like a fortress, and viruses are sneaky invaders trying to get in. In winter, when it's cold outside, people tend to stay inside more, where they're closer together, making it easier for the viruses to move from one person to another. Also, cold air can make the nose and throat feel a bit drier, which gives viruses a better chance to hang out and multiply. That’s why we get sick more often during winter.
Examples
- A family stays inside a warm house during winter, sharing the same air, making it easy for a cold virus to spread from one child to another.
- Cold air might make it easier for a person’s nose to get infected by a virus.
