When patients have dry throat in the morning, the reasons are as follows: 1. Chronic pharyngitis: Patients may usually have more voice speech, smoke too much, drink too much, eat spicy, stimulating food and other factors that can easily cause chronic pharyngitis, which can lead to repeated pain, dryness, burning, and foreign body sensation in the throat; 2. Dehydration: Failure to drink more water at night when sleeping to replenish the water lost in the body can easily cause dry throat in the morning; 3. The loss of water can easily cause the symptoms of dry throat in the morning; 3. Snoring: The more serious symptoms of snoring at night, often accompanied by continuous open-mouth breathing, can easily cause the loss of water in the mucous membrane of the throat, which can easily cause the symptoms of dry throat.
