Rest Helps
Step three: rest helps the fight! When you rest, your body can put more energy into your immune system. Grown-ups keep an eye on how high your fever goes, To make sure your body stays safe while it works.
A Closer Look
Let's take a closer look at your body's thermostat. Deep in your brain is a tiny control center, called the hypothalamus. Most of the time, it keeps you at just the right temperature.
