Why do you always sweat after drinking something cold very quickly regardless of the outside temperature. Is it normal?

It is not true that you always sweat after drinking something cold very quickly regardless of the outside temperature. Sweating in response to cold drink consumption is not a typical physiological response and is not considered normal. Sweating is usually triggered by factors such as high ambient temperature, physical exertion, or certain medical conditions. While drinking a cold beverage can cause a brief sensation of coolness in the mouth and throat, it should not lead to sweating unless other factors are present.

If you find that you are consistently sweating after drinking something cold, it may be worth consulting a healthcare professional to rule out any underlying medical conditions that could be causing excessive sweating.
