Repeated colds indicate that the body has weak immunity, making it susceptible to repeated infections by cold viruses, leading to symptoms of a cold.

Therefore, it is important to regularly exercise, get more sunlight, balance work and rest, and develop good living habits. Avoid smoking, alcohol, and staying up late; ensure sufficient sleep to allow the body to recover. Eat fresh vegetables and fruits and consume more protein-rich foods, such as milk, beef, and lean meats, to enhance the body's resistance.

It is crucial to keep warm, especially during weather changes, to avoid catching cold. Adjust your clothing accordingly and try to avoid crowded places during the cold season. If you must visit these places, it is advisable to wear a mask.
