I believe it actually increases. For example when you have a fever your body temperature is higher so you feel hot. When your hot you sweat to cool off in a way.
The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
