ELI5: How does the human body rises its temperature in order to cause a fever?
gpt
The part of your brain that controls your body temperature is called the hypothalamus. One of its jobs is to basically function as your body's thermostat. Your normal temperature is called a set point (around 37C, or 98.6F), which is the normal temperature the hypothalamus maintains. When you're sick, the hypothalamus can raise the set point in order to cause a fever. This is basically like turning the heat up on your thermostat at home.
