Excessive sweating from colds may be related to fever caused by colds, which is a phenomenon caused by abnormalities in the thermoregulatory center in the body due to viral infection. Colds are caused by viral invasion of the body, so that the respiratory tract becomes infected, and when the resistance is low, the invading viruses in the body continue to multiply, stimulating the body to develop an inflammatory response. Inflammatory response causes an increase in the number of pyrogen in the body, which leads to abnormal functioning of the normal thermoregulation point, resulting in an increase in the thermoregulation point, and therefore an increase in the body’s heat production and the emergence of fever. When the fever reaches a certain level, the body will have a protective reaction to increase the heat dissipation mechanism, mainly through the expansion of peripheral capillaries, so that the pores dilate, through increased sweating to take away the heat. When sweating a lot with a cold, drink plenty of water to ensure that the body is well hydrated, and warm water is recommended. If the cold symptoms worsen, it is recommended to actively seek medical advice and follow the doctor’s instructions to use medication.
