5. Mouth breathing
You may remember mouth breathing as the only way you have ever slept. This may be caused by the anatomy of your mouth and nose. However, it can be a sign of something more serious. Mouth breathing can be hazardous. Sleep apnea causes people to breathe through their mouth over their nose. Nasal congestion can cause someone to be more likely to mouth breathe. This blocks air from accessing the pathway when your tongue covers your throat airway during sleep. Therefore, it is essential to assess if mouth breathing is really the symptom of a greater condition.
