There are more reasons for being afraid of cold on a hot day. First of all, it is cold and fever. If a cold and fever appear in summer, this time there will be high fever and chills, bad wind, bad cold and fear of cold. In addition, patients who are usually very cold, even in summer, when it is so hot outside, may feel cold. Sometimes, the patient is frightened and will have this symptom of fear of cold. I have seen this kind of frightened patient in the clinic once before, because a patient was frightened by the sound of the doctor in the CT room when he was doing CT, and then he appeared to be afraid of cold in summer, and had to wear several pieces of clothes, while sweating and being afraid of cold. Of course, women also appear when they are sitting in the month, afraid of cold in the summer and air conditioning and wind, because the main reason is that the Qi is more deficient, blood is more deficient.
