A cold after freezing is a cold, or a cold. The so-called wind-cold cold refers to the cold, fear of cold, runny nose, body aches and discomfort, increased body temperature, and upper abdominal discomfort that occur after the body has been cold. The cold is common in autumn and winter, and can also be caused by rain in summer and prolonged stay in air-conditioned rooms. The basis of prevention of this disease is to keep warm, strengthen physical exercise, and pay attention to work and rest to improve immunity. Wind-cold is a self-limiting disease that lasts for about a week and does not require treatment in mild cases, but requires medication and food therapy in severe cases. In contrast, wind-heat colds occur in the warm season and are caused by the body feeling the wind, while many patients have wind-cold colds at the beginning due to the cold, but may change to wind-heat colds as the disease develops.
