The sweating of patients with colds is mostly due to the decrease in body resistance, rain, cold and other triggering factors that cause pathogens such as viruses, bacteria, mycoplasma and chlamydia to invade the body, causing inflammatory reactions of congestion and edema in the mucous membrane of the upper respiratory tract. At this time, the body’s immune response is intense, which can lead to an increase in endogenous pyrogenic sources in the body at any time, thus causing fluctuations in body temperature and even a tendency to gradually increase body temperature. At this time, the body will reflexively adjust its own body temperature, such as sweating away the body heat to lower the body temperature. Patients should closely monitor the change of body temperature and drink more warm water, juice or glucose saline to prevent excessive loss of body fluids that may lead to deficiency or even shock.
