What Causes Dry Mouth at Night?
Dry mouth at night, also known as xerostomia, can result from a variety of factors that disrupt the production of saliva or its balance in your mouth. Saliva is essential for keeping your oral tissues hydrated, aiding digestion, and controlling bacteria. Reduced saliva flow during sleep can be uncomfortable and may indicate underlying issues. Below are the most common causes of this condition:
Causes of Dry Mouth at Night
- Dehydration: Inadequate water intake during the day can lead to dryness at night. Drinking alcohol or caffeine can also exacerbate fluid loss.
- Mouth breathing: Sleeping with your mouth open due to nasal congestion or habitual breathing can result in moisture loss.
- Medications: Many drugs, such as antihistamines, diuretics, and antidepressants, list dry mouth as a potential side effect.
- Medical conditions: Conditions like diabetes, Sjögren's syndrome, or autoimmune disorders can impair saliva production.
- Smoking and alcohol use: Both habits contribute to oral dryness, especially overnight.
How to Prevent Dry Mouth at Night
To address nighttime dry mouth, try these solutions:
- Stay hydrated by drinking plenty of water throughout the day.
- Use a humidifier to increase air moisture in your bedroom.
- Switch to nasal breathing by addressing any sinus blockages or using nasal strips.
- Limit alcohol and caffeine intake before bed.
- Discuss alternative medications with your doctor if drug side effects are causing dryness.
