ELI5: Our body fight diseases by increasing the temperature, why betraying it by cooling ourselves down?

Your body is a house, pathogens are a thousand and thousand of cockroaches ramping on the floor.
Fever is basically the house habitant (immune system) being like "Oh fuck it, let's burn the fucking house down".

It's super effective but it can be very damaging, when a fever isn't really high, doctors usually advice to let it go and wait for it to decrease, when it raises to 103°F (40°c) and keeps increasing, it's time to stop the fever because it's going to do more harm than good (I think you start getting convulsion around 105 °F or 41°c and risk brain damage if it increases further).
