There are several factors that make the face feel hot: from a Chinese medicine point of view, it is usually a fire evidence, when the upper jiao fire starts, such as lung fire and heart fire, the face will feel hot. If we look at it from a psychological point of view, there are several factors that make the face feel hot: 1. When the sympathetic nerve is overexcited, it will expand the capillaries of the face, and at the same time excite the nerve center, which will cause the capillary filling of the face, thus causing the face to feel hot. 2. Redness, swelling, heat, pain, accompanied by peripheral discomfort and other clinical symptoms. In addition, when the face is particularly susceptible to viral infections, such as facial neuritis and trigeminal neuralgia, there will also be a clear case of conscious facial fever.
