What causes weakened immunity?

Your body has guards that help you fight off germs, kind of like how a castle has soldiers to keep out invaders.

When your immunity is strong, those guards are ready and able to do their job. But when it's weakened, they're not as good at fighting off the bad guys.

Sometimes, your body gets too busy with other things, like when you’re sick or running around a lot, and the guards don’t have enough energy. That’s like when you’re playing tag all day and then it's hard to run fast at the end of the game.

Other times, your body doesn't get the right food or rest, kind of like how you need snacks and naps to stay strong. If your guards don’t have what they need, they can’t fight as well.

So, immunity gets weaker when your body’s guards are tired or not getting enough help, just like you need good snacks and rest to keep playing tag all day! Your body has guards that help you fight off germs, kind of like how a castle has soldiers to keep out invaders.
