If cold symptoms repeatedly occur, it is primarily considered to be due to poor bodily resistance and physical fitness. In this case, it is crucial to focus on improving dietary nutrition by consuming foods rich in vitamin C and protein, eating smaller meals more frequently, and avoiding overeating at one time. Additionally, it is important to engage in active outdoor activities, increase physical exercise, enhance physical fitness, and improve personal resistance. It is also vital not to stay up late and to ensure adequate sleep, as the body promotes self-repair during rest and sleep, which can help alleviate cold symptoms more quickly. Besides these actions, it is necessary to follow a doctor's guidance and cooperate with the doctor to take the appropriate medications to treat the symptoms. Do not stop or reduce the medication dosage on your own to avoid repeated illness and prolonged recovery.
