When the wind blows and you catch a cold, consider that your body’s resistance is relatively low and you are easily attacked by external viruses and bacteria. In this case, you should use anti-cold medications after catching a cold, such as antiviral oral liquid, Banlangen granules, cold and fever granules, etc. During the treatment period, you should drink more water, eat more vegetables, keep the indoor air circulating, try to avoid exertion, and take more rest. After recovering from the cold, we should strengthen physical exercise to enhance physical fitness. For people who are old, young, weak, have low immune function or have respiratory diseases, they can get influenza vaccination in autumn, which has a certain preventive effect on the cold.
