This may be related to:
- nasal congestion
- Allergies
- deviated septum
- intense snoring
In some cases it can also be associated with sleep apnea, a disorder in which breathing stops for a few seconds several times a night.
This causes less oxygenation, greater effort of the heart and a waking up with tiredness and dry mouth.
3. Diabetes or high blood sugar levels
Dry mouth can also be one of the first symptoms of diabetes.
When your blood sugar level rises, your body tries to get rid of excess glucose through your urine. This process causes increased fluid loss.
As a result, the following appear:
- Be Constant Thirst
- Need to drink water at night
- dry mouth upon waking
For this reason, many doctors pay special attention to this symptom.
4. Dehydration
Over the years, the body loses some of the natural sensation of thirst.
Many people simply don’t drink enough water during the day.
During the night the body continues to use fluids for its normal functions, and if the reserves are low, in the morning symptoms such as:
- dry mouth
- dry lips
- feeling intensely thirsty
5. Stress and emotional tension
The nervous system can also influence saliva production.
When a person lives under prolonged stress, the body releases tension hormones that can affect the functioning of the salivary glands.
This means that less saliva is produced during the night and when you wake up that uncomfortable dryness appears.
