If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, ensure adequate hydration to maintain moisture in the throat and maintain appropriate indoor humidity to avoid dry environments.

Generally, a dry throat with a strong sensation of dehydration may be caused by insufficient water intake, dry environment, chronic pharyngitis, allergic pharyngitis, Sjögren's syndrome, or other reasons. If discomfort symptoms occur, it is recommended to seek timely medical consultation and treatment at a正规 hospital. Detailed analysis is as follows:

1. Insufficient water intake: Inadequate hydration leads to poor moisture in the pharyngeal mucosa, easily causing a dry sensation. Increase water intake by drinking small amounts of warm water frequently throughout the day, and avoid replacing water with beverages.

2. Dry environment: Low air humidity causes excessive evaporation of moisture from the pharyngeal mucosa, resulting in dryness and discomfort. Use a humidifier to increase indoor humidity, place a basin of water indoors, and wear a mask when going outdoors.

3. Chronic pharyngitis: Long-term inflammatory irritation of the pharyngeal mucosa reduces its secretory function, leading to dryness and a foreign body sensation. Follow your doctor’s instructions to use medications such as Pharyngitis Tablets, Qinghou Luyan Granules, or Watermelon Frost Throat Lozenges, and avoid spicy and irritating foods.

4. Allergic pharyngitis: Allergens stimulate the pharyngeal mucosa, triggering an inflammatory response that results in dryness and itching. Under medical guidance, take antihistamines such as Cetirizine Hydrochloride Tablets, Loratadine Capsules, or Ebastine Tablets, and avoid allergens like dust and pollen.

5. Sjögren's syndrome: Autoimmune abnormalities damage salivary glands, reducing saliva production and causing persistent throat dryness. Medications such as Methotrexate Tablets, Hydroxychloroquine Sulfate Tablets, or Total Glucosides of Paeony Capsules may be used under medical supervision. In severe cases, salivary gland replacement therapy might be considered.

In daily life, ensure adequate water intake to maintain throat moisture; maintain appropriate indoor humidity and avoid dry environments; stay away from allergens and irritants to reduce throat irritation; and undergo regular health check-ups for early detection and intervention of diseases.
