There are three reasons why the body sweats and can feel cold: First, at the beginning of the cold, when bacteria, viruses and certain pathogenic microorganisms invade the body, causing the body to produce an immune response, when the antigenic antibodies trigger a reaction, the body will consciously eliminate the pathogenic microorganisms from the body, then it will sweat, but the body temperature setting point will then shift down, so it will feel consciously hot. Second, in the case of heat stroke, there will be cold sweat, but the body temperature decreases, this is because the heat caused by the hypothalamic nerve center temperature adjustment point shift, and caused by the cold sweat, but feel cold situation. Thirdly, hypovolemic shock and infectious shock also have the symptoms of pale face, wet and cold skin, and cold sweat around the body.
