Mouth Breathing: Common Does Not Mean Normal

If your mouth is regularly open for breathing, it is worth asking why.

Two broad possibilities

Sometimes the nose is difficult to breathe through. At other times, the nose may be usable but mouth breathing has become a learned pattern.

Possible contributors include:

• nasal congestion or obstruction
• allergy
• enlarged nasal tissues
• low tongue posture
• poor lip seal
• long-standing habit

Why notice it?

The mouth and nose do not condition air in the same way. Persistent mouth breathing can travel with dry mouth, snoring, altered tongue posture and disturbed sleep.

A simple awareness check

During quiet daytime rest, notice:

• Are your lips together comfortably?
• Is breathing silent and nasal?
• Where is your tongue resting?

Do not force the mouth closed if nasal breathing feels difficult.

Get checked: Persistent nasal difficulty or inability to breathe comfortably through the nose deserves evaluation.
