The body is hot but feels cold should be in the early stages of fever, when the body temperature continues to rise but has not yet reached the thermoregulation point, so it will feel cold.
Fever is due to a variety of reasons caused by the rise in the thermoregulation point, the body heat production increases so that the body temperature rises to reach the thermoregulation point, before the body temperature has not reached the thermoregulation point, the patient will feel cold. Fever is mostly caused by infections, in which a pyrogen enters the body to change the thermoregulation point and induces a series of inflammatory reactions, causing the patient to become feverish.
In the early stage of fever, if the patient feels cold, he/she can add more clothes and drink more hot water. If the body temperature exceeds 38.5℃, antipyretic drugs, such as ibuprofen, can be taken under the guidance of the doctor. Try not to get cold during the fever, eat a light diet, do not eat spicy and stimulating food.
If the fever is difficult to subside, you should consult a doctor promptly.
