Dry mouth and thirst upon waking each morning may be caused by several factors:
1. Environmental factors: Dry indoor air can lead to bodily dehydration during sleep, resulting in a dry mouth upon awakening.
2. Personal habits: If elderly individuals tend to breathe through the mouth at night, or have protruding front teeth that affect proper lip closure, excessive evaporation of moisture from the oral cavity can occur, leading to dryness.
3. Nutritional deficiencies: Deficiencies in certain nutrients, such as vitamin B2, may also cause dry mouth and could be accompanied by symptoms like cheilitis or angular stomatitis.
4. Medical conditions: Diseases such as diabetes and Sjögren's syndrome can also contribute to morning dry mouth.
It is recommended to adjust indoor humidity, improve breathing habits, and maintain balanced nutrition according to individual circumstances. If symptoms persist, prompt medical evaluation is advised.
