A fever is when your body gets hotter to fight off germs that are making you sick.
Imagine your body is like a cozy house, and germs are like tiny troublemakers sneaking in through the door. When they get inside, your body says, "Hey! I need to warm up so I can kick them out!" So it turns on its heat engine, which makes you feel hot, that's your fever!
How Your Body Turns On Its Heat Engine
Your body has a special control center called the thermostat (like the one in your house). When germs are inside, this thermostat says, "Time to warm things up!" It sends messages all over your body, telling it to make more heat. That's why you feel shivery at first, your body is trying to get warmer.
Once your body gets hotter, it’s like turning on a space heater in every room, the germs can't stand the heat and start to leave. Soon, you’ll feel better because your body has kicked the troublemakers out!
