The cause of hyperthermia in children with cold hands and feet is due to the fact that the body temperature is in an ascending phase and the heat is around the internal organs, resulting in cold hands and feet. The fever cycle mainly consists of the period of rise, persistence and fall of body temperature. In the period of rising body temperature, the body heat production is greater than heat dissipation, in this case due to chills and other circumstances will cause the continuous production of heat, heat will mostly gather around the internal organs, surrounded by the peripheral circulation is temporarily significantly poorer, which will cause cold hands and feet, and so on the heat continues in the plateau period, the hands and feet will naturally be warm and hot.
