Skin flushing is a sudden reddening of the face, neck and upper chest. It is described as episodic attacks of redness of the skin along with a warm sensation or burning of the face, neck and the upper trunk and abdomen.
In the case of a heat stroke red, hot, dry skin is caused by rapid changes in temperature and heat exposure. The skin may turn red as the body temperature rises. At this stage the skin’s sweat glands become blocked and the sweat produced cannot get to the surface of the skin to evaporate. This can trigger inflammation and cause a heat rash. The rash may be visible as red bumps on the skin or a prickly or itchy feeling that also goes by the name of prickly heat.
Additionally, flushed skin may also appear as reddened skin with tiny blisters due to the inflammation. If the skin is hot to touch and the individual has an internal temperature of 105 degrees, then they will need to see a doctor as soon as possible.
