In autumn, the temperature difference between day and night increases, and the weather also becomes drier, which leads to the anticipated arrival of colds.

If the cold is accompanied by clear nasal discharge and symptoms like sneezing, then it is classified as a cold caused by wind-cold. If during the cold, thick yellow nasal discharge occurs, along with a hoarse voice and sore throat, these symptoms can be identified as a wind-heat cold. After catching a cold, it is important to keep warm to avoid catching cold again, eat more fruits and vegetables, improve physical fitness, and enhance immunity.
