Pyrexia

Pyrexia, also known as fever, is an increase in the body temperature of an individual beyond the normal range. This increase in temperature is usually considered dangerous, but it is a natural defensive mechanism of the body to fight against infections. Pyrexia is usually associated with other symptoms such as lethargy, headache, cough, and cold. A mild increase in body temperature can be relieved by over the counter medications. A sudden and higher increase in the body temperature beyond the normal range should be treated medically as it could be due to some major illnesses such as a brain haemorrhage or cancer.
