3. Fever
A fever is the body’s natural reaction to a virus or an illness. Fevers are a sign of an underlying condition and are common with infections. Fevers can range from mild to severe, and most can be treated with medication. In rare cases, a fever may be so high that it is life-threatening and require hospitalization and immediate treatment. The hypothalamus is a part of the brain that regulates body temperature.
When a person becomes sick, the hypothalamus attempts to reset the body so it can fight the infection better. It raises the temperature of the body to do so. There are numerous things that can be done to treat a fever such as medication, cool baths, and plenty of fluids. In most cases, the fever will continue to come back until the infection is cleared up. It could last several days or reduce as soon as the patient receives treatment for the disease.
