Why Do Some People Get Sick More Often Than Others?

Some people get sick more often because their body isn't as strong at fighting off germs. It's like having a superhero who can take down villains quickly, and one who needs help from friends to win the battle. The stronger your body is, the fewer times you get sick.

How the Body Fights Germs

When germs enter your body through your nose or mouth, they try to make you feel bad by causing a cold or flu. Your immune system, which is like a team of soldiers, works hard to fight them off. If this team is strong and healthy, it can win quickly, but if it's tired or not well, the germs might stay longer and cause more sickness.
