For a minor cold, it is possible for it to heal on its own. In the case of a minor cold, it may not even be necessary to use medication. Simple daily care, such as maintaining a light diet, drinking more water, eating more fruits, and avoiding spicy, irritating, greasy, and raw cold foods, might suffice.

Furthermore, it is important to ensure ample sleep and rest, avoid staying up late and overworking. Through these general approaches, the patient's cold may gradually recover on its own. However, it is important to note that even a minor cold can sometimes lead to complications like pneumonia.

Therefore, even in cases of minor colds, it is advisable to monitor the condition. If cold symptoms persist or if there are signs of a bacterial infection, such as coughing up substantial amounts of purulent sputum, high fever, and other related conditions, it is necessary to visit a hospital in a timely manner to investigate the cause and receive appropriate treatment.
