Feeling dry mouth and tongue after drinking tea may be caused by several factors:
1. It could be due to dehydration. The human body requires approximately 2000–2500 ml of water daily; insufficient intake or excessive loss through urine or other means may lead to dry mouth and tongue.
2. Certain medications, such as antihistamines and diuretics, may cause symptoms of dry mouth.
3. Oral conditions like xerostomia (dry mouth syndrome) can also reduce saliva production, resulting in dryness. Additionally, the tannins in tea might form a waterproof film on the tongue, causing a dry sensation. Drinking tea that is excessively hot may also burn the oral tissues, contributing to dry mouth.
Therefore, if dry mouth and tongue occur after drinking tea, it is recommended to drink an appropriate amount of water, check for medication side effects, maintain good oral hygiene, and adjust tea consumption habits according to individual conditions.
