When you sleep with your mouth open, gravity allows the saliva that would normally be swallowed to pool at the front of the oral cavity and leak out onto your pillow.
Common Causes of Nasal Congestion:
-
Seasonal Allergies: Allergic rhinitis triggers inflammation and swelling in the nasal linings.
-
Deviated Septum: A physical displacement of the cartilage dividing the nostrils can permanently restrict airflow through one or both sides.
-
Chronic Sinusitis: Long-term inflammation of the sinuses leads to mucus buildup and blockages.
-
Nasal Polyps: Non-cancerous growths inside the nasal passages can physically block the airway.
Addressing the root cause of your nasal congestion—whether through air purifiers, nasal strips, or saline rinses—is often the first and easiest step to resolving nighttime drooling.
2. Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea is a serious sleep disorder characterized by repeated pauses in breathing throughout the night. These pauses occur when the muscles in the back of the throat temporarily relax and collapse, blocking the airway.
