Every morning upon waking, my throat feels very painful, so I always start by drinking a glass of water to soothe it. Could you please advise what might be causing throat pain after sleep?

Sleeping with the mouth open and living environment can both lead to a sore throat upon waking. Patients with rhinitis often experience nasal congestion, which causes them to breathe through their mouths, resulting in dryness and pain in the throat. A high room temperature, high humidity, or a dry environment can also easily trigger throat discomfort. In daily life, it's important to maintain a light diet, avoid spicy and irritating foods, and consume more vegetables and fruits.
