"understanding fever"

Fever is a temporary increase in body temperature, often due to an infection or illness. It is a common symptom of many conditions, including viral and bacterial infections, and acts as a defense mechanism, helping the body fight off pathogens. A fever typically occurs when the body's hypothalamus raises the body's set point in response to chemicals called pyrogens, which are released during infection. While a mild fever may not be dangerous and can help with healing, a high fever or one that lasts for a prolonged period can indicate a more serious condition and may require medical attention.
