What causes a dry, itchy throat and coughing?

Dry throat, itching, and coughing are common symptoms that may be caused by the following reasons: 1. **Respiratory tract infections**: Including viral or bacterial laryngitis, pharyngitis, and upper respiratory tract infections, which are often accompanied by symptoms such as dry throat, itching, and coughing. These infections can cause inflammation and irritation of the throat mucosa, leading to discomfort. 2. **Allergic reactions**: Allergies to airborne allergens such as pollen, dust, or pet dander may cause dry throat, itching, and coughing. Allergic reactions are usually accompanied by other allergy symptoms, such as nasal congestion and runny nose. 3. **Environmental factors**: Dry air, smoking, or exposure to irritating chemical substances can lead to dry throat, itching, and coughing. Dry air can cause the throat mucosa to become dry and irritated. If symptoms persist or are accompanied by severe discomfort, it is recommended to seek medical attention. Improving the living environment and avoiding irritants can effectively alleviate these symptoms.
