After heat stroke in children, the main manifestations are abnormalities in the thermoregulatory center or symptoms of the central nervous system. In the early stages, the symptoms usually include dizziness, headache, nausea, vomiting, poor mental status, excessive sweating, or lack of mental concentration, and incoordination of the arms and legs. As the symptoms slowly worsen, fever may appear, accompanied by flushing or flushing of the skin, sweating and dry lips. If the symptoms worsen further and reach the symptoms of severe heat stroke, there will be a persistent high fever, which can reach 39.5 degrees or even 40 degrees or more, accompanied by loss of consciousness, coma, shock, convulsions and other symptoms.
