Detailed explanation-4: -By raising the temperature of the body, our immune system is stopping the virus or bacteria from growing. Our immune system begins its work by telling the brain that we need to raise the thermostat to a higher body temperature. Once the higher temperature is set, your body begins working to increase its temperature.

Detailed explanation-5: -The above-normal temperatures are thought to help defend against microbial invasion because they stimulate the motion, activity, and multiplication of white blood cells and increase the production of antibodies.
