Definition & Meaning of "fever"

WHat is a "fever"?

A fever occurs when the body's temperature rises above its normal range, typically in response to an infection or illness. This increase in temperature helps the body fight off the infection by making it harder for bacteria and viruses to survive. Common symptoms of a fever include feeling hot, sweating, chills or shivering, headaches, muscle aches, and fatigue. In most cases, a fever is not dangerous and can be managed at home with rest, plenty of fluids, and over-the-counter medications to reduce discomfort. However, if a fever lasts for more than a few days, is very high, or is accompanied by intense symptoms, it is important to seek medical attention.
