Introduction
Under normal circumstances, the throat refers to the pharynx. Possible causes of dryness, itching, and coughing in the throat include dry environment, excessive use of the voice, chronic pharyngitis, allergic pharyngitis, and reflux pharyngitis. To prevent these symptoms, it is recommended to maintain an appropriate indoor humidity level in daily life and avoid excessively dry environments. Additionally, schedule voice usage properly and avoid overusing the throat.
Generally speaking, the throat refers to the pharynx. Possible causes of dryness, itching, and coughing in the throat include dry environment, excessive use of the voice, chronic pharyngitis, allergic pharyngitis, and reflux laryngitis. A detailed analysis is as follows:
1. Dry Environment
When the ambient humidity is low, the moisture content in the air decreases, causing the pharyngeal mucosa to lose moisture easily, become dry, and subsequently lead to sensations of dryness and itching, as well as coughing. Maintaining an appropriate indoor humidity level—for example, by using a humidifier—and drinking plenty of water to ensure adequate hydration can help. Avoid prolonged exposure to dry environments.
2. Overuse of the Voice
Speaking for extended periods or shouting loudly can overwork the throat muscles and mucosa, leading to fatigue, congestion, and swelling, which may result in dryness, itching, and coughing. Arrange speaking times reasonably, avoid continuous talking for long durations, and allow appropriate rest periods for the throat to recover.
3. Chronic Pharyngitis
Chronic pharyngitis is usually caused by repeated episodes of acute pharyngitis, long-term irritation from smoking or alcohol consumption, and environmental factors. Long-term chronic inflammation of the pharyngeal mucosa leads to congestion, swelling, and increased secretions, which irritate the throat and cause symptoms such as dryness, itching, and coughing. It may also be accompanied by sensations of a foreign body in the throat, burning, and dryness. Treatment may involve using medications such as compound borax mouthwash, cetirizine iodine tablets, and throat lozenges, as directed by a physician.
4. Allergic Pharyngitis
Allergic pharyngitis may be triggered by allergens such as pollen, dust mites, or animal dander. These allergens irritate the pharyngeal mucosa, causing congestion, swelling, and allergic reactions that lead to dryness, itching, and coughing. Additional symptoms may include sneezing, runny nose, and itchy eyes. Treatment options may include medications such as cetirizine tablets, loratadine syrup, and montelukast sodium tablets, as recommended by a doctor.
5. Reflux Laryngitis
Reflux laryngitis may occur when stomach acid flows back into the throat area, irritating the mucosa. The acidic substances in gastric juice irritate the throat mucosa, causing mucosal damage and inflammatory reactions, which result in dryness, itching, and coughing. Accompanying symptoms may include hoarseness, a sensation of a foreign body in the throat, and a burning sensation behind the breastbone. Treatment options may include medications such as omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated tablets, and lansoprazole enteric-coated tablets, used under a doctor's guidance.
To help prevent these symptoms, it is recommended to maintain an appropriate indoor humidity level in daily life and avoid excessively dry environments. Arrange voice usage reasonably and avoid overusing the throat.
