ELI5: Why does taking a warm bath when you have a fever feel so cold?

Because - in order to slow down viral multiplication - your body increases the thermostat of your body. So what normally feels comfortable suddenly feels cold.

Update: That's also why you sweat when you're recovering. The body lowers the thermostat back to normal temperature. Everything feels more hot as when you were sick.
