How is face often feverish to return a responsibility?

First: the situation of fever, in general, the heat will make the skin vascular dilation, resulting in facial flushing. Although cold makes blood vessel contract, when temperature rises, blood vessel can counteract elasticity dilate, cause blush. But there are also some people, in extremely cold temperatures, may also be due to abnormal expansion of blood vessels caused by blushing. The clinical manifestations were filiform, punctate, stellate or flaky erythema on the face.

Second: when the temperature difference is too large, for example, from the cold air to the air-conditioned room, the microvessels lose their elasticity in repeated contraction and expansion, which is reflected in the cheeks and nose, making the cheeks red and tingling. In the early stage, the face fever can immediately return to its original state, but if it continues for a long time, the blood vessels will contract and lose the function of expansion. In the excessive expansion state, the face will harden, making it look red at ordinary times. In severe cases, the head down after the head will also appear face flush symptoms. This kind of symptom is relatively calm in spring, summer and autumn, and turns serious in winter.

Third: from a medical point of view, face fever refers to the change of temperature or mood, which is more likely to turn red than other people, and the color is dark and lasts for a long time. There are blood vessels in the skin, which expand or contract under the influence of nerve factors, especially in the buccal region where there are abundant capillaries, so the cheeks are more prone to redness. If blush occurs only in winter, it has more to do with the change of temperature.
