Cough is a common symptom of asthma patients and should be paid attention to in daily life. For example, in terms of food selection, eat more light foods, such as tomatoes, cucumbers, cabbage, apples, pears and other fruits and vegetables, and eat less fatty foods such as fatty meats to avoid phlegm. Pay attention to good hygiene in daily life, make the room ventilated and clean the dust frequently. Avoid contact with common allergens such as pollen, food additives, etc. You should also take part in some exercise to enhance your physical fitness, increase your cold resistance, and better fight against diseases. Pay attention to getting more rest at night and maintaining a good spirit to face life during the day.
