Cold and fear of cold is a symptom of wind-cold cold, caused by cold attack, low resistance and acute upper respiratory tract infection. Especially in the early stage of wind-cold cold, symptoms such as fear of cold, cold, shivering of limbs, fever and runny nose easily appear. After a cold, if the appetite is reduced, nutrition cannot keep up, and the body’s energy metabolism is impaired, it leads to insufficient heat production and cold shivering. If people with low blood pressure or deficiency of qi and blood have poor supply of peripheral blood circulation after a cold, the supply of oxygen and energy will not be sufficient, and cold extremities will also occur. If the fever decreases too quickly during the cold, the body temperature decreases too quickly and too much heat is discharged, the symptoms of chills may also occur. During cold and flu, you need to pay attention to keep your body warm and drink more ginger soup, brown sugar water and mutton soup to warm up your body. The diet should be light and nutritious. You also need to pay attention to increase clothing in time to avoid repeated cold.
