This is caused by the thermoregulatory center, especially in patients with fever, who are particularly prone to chills. As the body temperature rises, the chills and chills will disappear and be replaced by a fear of heat as the body temperature reaches its peak. These patients must monitor their body temperature and control it in time to keep it within the normal range. If the body temperature exceeds 38.5℃, you can take oral antipyretic drugs, and drink more water and keep warm to avoid further aggravation of the cold.
