Collection: Thermometer

Fever is a temporary elevation of body core temperature. It is part of a defensive response to infection by a virus.

When you develop a fever, you feel cold, heat generation in your body increases (achieved by shivering) and heat loss decreases. When a fever breaks, either naturally or because you have taken an antipyretic like paracetamol, you feel warm. Your reactions include increasing the flow of warm blood to the skin and sweating, which helps to bring the body’s core temperature back to normal.
