How do you deal with a fever in children?

Dr Sarah Jarvis MBE A part of your brain called the hypothalamus controls your body temperature. This usually varies slightly throughout the day. A high temperature is called a fever (or sometimes a high fever). Fever itself is not an illness. A fever is usually a symptom of an underlying condition, most often an infection. Night sweats occur when you sweat too much at night. They can be related to a fever but they can also occur without a fever. https://patient.info/health/fever-and-night-sweats-leaflet
