🤒 What causes a fever?

When you get sick, your body gets hotter to fight the germs! 🌡️ It's like your body turns into a little superhero to make you feel better. 🦸‍♂️

Sometimes, when you have a cold or an infection, your body temperature goes up. That's called a fever! It means your body is working hard to get you healthy again.

A fever happens when your body's temperature rises because it's fighting an infection or illness. 🤒 Your brain has a special part called the hypothalamus that acts like a thermostat. When germs attack, it turns up the heat to help your immune system work better! 🌡️

Common causes include colds, flu, ear infections, or even vaccinations (which are good because they teach your body to fight germs!).

A fever is a temporary increase in body temperature, usually caused by an infection or illness. 🔥 It's part of your immune system's defense mechanism. Here's how it works:

• When harmful bacteria or viruses enter your body, white blood cells release chemicals called pyrogens.
• These pyrogens signal the hypothalamus (your brain's thermostat) to raise your body temperature.
• A higher temperature helps your immune system work faster and makes it harder for germs to survive.

Fevers can also be caused by inflammation, heat exhaustion, or certain medications.
