Sleeping with your mouth open might seem harmless, but it can have negative effects. This habit is common, often resulting from nasal congestion, allergies, or anatomical factors like a deviated septum.
Why Do Some People Sleep with Their Mouth Open?
Several factors can lead to mouth breathing during sleep:
- Nasal Blockage: Allergies, colds, or sinus issues make it difficult to breathe through the nose.
- Anatomical Issues: Conditions like a deviated septum or enlarged tonsils can obstruct nasal airflow.
- Sleep Apnea: Obstructive sleep apnea often causes mouth breathing as the body compensates for airway blockages.
