Children are significantly more susceptible to fever than adults. Fever can occur with even minor health irregularities and serves as a protective mechanism of the body against infections. It is not a disease per se but a natural reaction where the body mobilizes its defenses to combat pathogens. A slightly elevated temperature in children is typically between 36.5 and 37.5 degrees Celsius. Temperatures just under 38 degrees are referred to as elevated temperatures, from 38 degrees as fever, and over 39 degrees as high fever.

Taking the temperature rectally is the most accurate method, especially for children under three years old. Ear and forehead thermometers provide reliable readings, while heat-sensitive strips can be inaccurate. Physical exertion, emotional stress, and ambient temperature can influence body temperature. When fever is present, the temperature should be measured and recorded regularly, particularly in children up to the age of five.

Fever-reducing measures are necessary only at temperatures above 38.5 degrees, as high fever can put a significant strain on the body. It is important for a child with a fever to drink plenty of fluids, as the elevated temperature leads to increased fluid loss. Wraps with lukewarm water around the calves and arms or a damp washcloth on the forehead can help reduce the temperature without medication. If necessary, homeopathic remedies or traditional fever-reducing medications like paracetamol or ibuprofen can be used, although aspirin should be avoided in children and adolescents.
