Cough is a natural reaction of the body to remove foreign bodies or pathogens from the respiratory tract. If you have a bad cough and want to relieve symptoms quickly, you can try the following methods: 1. Drink enough water: keeping your body hydrated can dilute mucus and relieve cough symptoms. 2. Use air with moderate humidity: Dry air may stimulate coughing. You can use a humidifier or turn on a hot shower in the bathroom to increase air humidity. 3. Use cough medicine: You can use over-the-counter cough syrup or cough tablets, but please follow the instructions. If the cough continues to be severe or accompanied by other symptoms, please consult a doctor. 4. Gargle with warm salt water: Gargling with warm salt water can relieve throat discomfort and reduce cough. 5. Avoid irritating substances: Avoid smoking and exposure to irritating gases or dust, which may aggravate cough symptoms. 6. Have a good rest: Adequate rest can enhance immunity and help the body recover faster. If the cough symptoms continue to be severe or accompanied by other symptoms (such as dyspnea, chest pain, etc.), it is recommended to seek medical advice in time. []
