What Causes Dry Mouth and Throat During Sleep?
Disease description:
My husband always says he feels thirsty and wants to drink water while sleeping—not truly thirsty, just with a dry mouth that needs moisture. So I’d like to ask: What causes dry mouth and throat during sleep?

Dry mouth and throat commonly occur when bedroom humidity is low, temperature is high, and the body does not receive adequate hydration. Adjusting indoor environmental conditions and drinking more water—ideally two hours before bedtime—may help alleviate this issue. Other potential causes include insufficient fluid intake or excessive salt consumption. Additionally, waking up with a sensation of dry mouth and throat may indicate hyperthyroidism, which often leads to excessive sweating. Patients experiencing these symptoms are advised to seek timely medical evaluation and treatment.
