Patients with dry throat when sleeping with air conditioning are often caused by excessive dryness in the indoor space. Putting some water basins in the room or using nebulizer to humidify the indoor space can help improve the symptoms of dry throat. Patients also need to pay attention to drink more water to moisten the mucous membrane of the throat, usually avoid excessive use of voice to speak, avoid too much spicy, stimulating diet and tobacco and alcohol. In addition, some patients may have more serious snoring and continuous open-mouth breathing during sleep, which is more likely to occur and even aggravate the symptoms of dry throat, so we need to pay attention to a comprehensive examination of the entire upper respiratory tract, comprehensive analysis of the specific causes and take targeted treatment measures.
