Fever is a common medical condition characterized by an increase in body temperature above the normal range. In most adults, a fever is considered present when the body temperature rises above 100.4°F (38°C). It is usually caused by an infection or inflammation in the body, which triggers the release of chemicals that stimulate the hypothalamus, a part of the brain that regulates body temperature. The hypothalamus then signals the body to increase its temperature by shivering, reducing sweating, and causing blood vessels in the skin to constrict. This response is a natural defense mechanism of the body to fight off infections, as many microorganisms cannot survive at higher temperatures.
Fever can be accompanied by other symptoms such as sweating, chills, headaches, muscle aches, fatigue, and loss of appetite. It is often treated with over-the-counter fever-reducing medications such as acetaminophen or ibuprofen, along with rest and hydration. However, if the fever persists for an extended period of time or is accompanied by other severe symptoms, it is important to seek medical attention. In some cases, a fever can indicate a more serious underlying condition, and prompt diagnosis and treatment can be crucial in preventing complications.
