Fevers are defined as a common symptom characterized by an abnormally high body temperature, typically as a result of an illness or infection. Medically referred to as pyrexia, fevers are the body's natural response to fight off infections and other pathological conditions. In general, a normal body temperature ranges between 97°F (36.1°C) and 99°F (37.2°C), and a fever is typically considered to occur when the body temperature rises above this normal range.
Fevers are often accompanied by various signs and symptoms, including sweating, chills, headache, muscle aches, fatigue, and elevated heart rate. They can present as a standalone condition or occur as a result of an underlying disease, such as the flu, bacterial or viral infections, or inflammatory conditions like rheumatoid arthritis.
Measuring body temperature is crucial in diagnosing and treating fevers. This is commonly done using a thermometer, either orally, rectally, or axillary. Fevers themselves are generally not dangerous, except in rare cases when they are exceptionally high or prolonged, indicating severe underlying conditions.
Treatment of fevers depends primarily on addressing the underlying cause. Common methods of managing fevers include drinking plenty of fluids, taking over-the-counter fever reducers such as acetaminophen or ibuprofen, and adopting measures to reduce discomfort, such as wearing lightweight clothing, applying cool compresses, or taking lukewarm baths.
It is important to seek medical attention if a fever is accompanied by severe symptoms, lasts for an extended period, or affects infants, young children, elderly individuals, or people with weakened immune systems.
