Common allergens for allergic cough include pollen, dust, dust mites, and seafood. If a patient is allergic to these allergens, they should avoid contact with them as much as possible. It is important to strengthen the body through regular exercise and a balance of work and rest. Increase nutrition and eat more high-quality, high-protein foods to enhance the body's resistance. Additionally, keep warm and avoid catching cold, especially during the winter and spring seasons when temperature differences between morning and evening are significant, and adjust clothing accordingly. Change unhealthy lifestyle habits: do not smoke, do not drink alcohol, do not stay up late, and avoid the dangers of secondhand smoke to protect lung function.
