Waking Up With a Dry Mouth? Here’s What Your Body Might Be Telling You
Waking up with a dry mouth is common and usually isn’t a sign of something serious. It means your mouth isn’t producing enough saliva during sleep or you’re breathing through your mouth.
Possible causes include:
- Mouth breathing from nasal congestion or a blocked nose
- Snoring or sleep apnea
- Dehydration
- Medications, including some antihistamines, antidepressants, and blood-pressure medicines
- Smoking or alcohol, which can contribute to dryness
- Dry bedroom air
- Certain medical conditions that affect saliva production
What you can try
Drink adequate fluids during the day, address nasal congestion, avoid excessive alcohol and tobacco, and consider a humidifier if the air is very dry. Good oral hygiene is especially important because reduced saliva can increase the risk of cavities.
If dry mouth is persistent, very severe, or accompanied by loud snoring, witnessed pauses in breathing, excessive daytime sleepiness, difficulty swallowing, or frequent urination/thirst, talk with a healthcare professional or dentist.
