Cold sweating is when you are cold and perspire. It can be caused by weakness, fever, relapse of the disease and so on. 1. Weakness: the body’s immunity is lower when you have a cold, and the patient’s body consumes more energy when you have a cold, which can lead to chills and sweating even after the cold is over. 2. Fever: Some patients may suffer from fever. When the body temperature rises during fever, it will lead to an imbalance between heat production and heat dissipation, resulting in chills and sweating. 3. Relapse: Some patients who have a good cold do not take good care of themselves, which may lead to a relapse of the cold, resulting in chills and sweating, accompanied by headache, coughing, sneezing, runny nose and other symptoms. After the cold is over, the cold and sweating may also be caused by other reasons, it is recommended that the patient go to the hospital, under the guidance of a professional doctor to treat the symptoms.
