Waking Up With a Dry Mouth? Here’s What Your Body Might Be Telling You
Waking with a dry mouth is common and doesn’t necessarily mean something is wrong. During sleep, saliva production naturally decreases, and mouth breathing can make dryness more noticeable.
Common reasons include:
- Mouth breathing or nasal congestion
- Snoring or obstructive sleep apnea
- Dehydration
- Medications, including some antihistamines, antidepressants, and blood-pressure medicines
- Smoking or alcohol
- Dry indoor air
- Conditions that reduce saliva production
What you can do
Drink enough fluids during the day, address nasal congestion, avoid excessive alcohol and tobacco, and consider a humidifier if your bedroom is very dry. Good dental hygiene is especially important because persistent dry mouth increases the risk of tooth decay.
If dryness is persistent or severe, or you also have loud snoring, pauses in breathing during sleep, excessive daytime sleepiness, difficulty swallowing, or unusual thirst and frequent urination, talk with a doctor or dentist.
