eli5: If fever is our body’s response to kill an infection, then why do we take medicines like paracetamol that control the fever?

Also, I get that the fever can get really high at some point, which causes other effects, but why is our body not able to control its response to the infection so as to not do more harm with the fever?

Actually the fever is almost always a good thing and that you shouldn’t be taking paracetamol.

The only time you should take paracetamol is if the fever get’s soo high it’s a risk or danger to you.

Many people take paracetamol to limit the fever so they can still work and do other stuff, but that’s not optimum for fighting the infection.

For comfort. A fever *can* slow the rate of infection when your body is fighting many common illnesses, but so can fortifying your body with adequate rest and nutrition. Side effects of a fever can include shivering, sweating and body aches. It’s hard to rest when you’re uncomfortable.

For a long time medicine didn’t have a lot of nuance when it came to when to medicate and when not to. We gave out antibiotics for anything we thought might be a bacterial infection, we used medication to control any fever, etc.

In more recent years we’ve started being a lot more nuanced about such things, so it’s no longer generally advised to medicate a low-grade fever.

You can survive the fever, we just take medicine because we’d rather be sick longer, but feel slightly better than be feverish and sweaty for the time needed. Your body’s natural reaction to infection and causing a fever will _almost_ never be dangerous, you dont suffer brain damage until around 108, and your body isnt going to go that high. That type of harm is usually only when youre body is someplace it can not effectively regulate your body temperature, like in a hot car.

I should also add, for things like an infection, people are often prescribed anti-biotics which do a pretty good job of killing infections quickly. So instead of being miserable a long time with a fever, we take medication to kill the infection and medication to lessen the fever and feel slightly better
