Nasal Congestion With A Face Mask
Many people report nasal congestion and difficulty breathing through their nose while wearing a face mask. What is causing this?
Heat
The accumulation of heat from breathed air in the mask causes dilation of blood vessels, tissue swelling in the nose
Humidity
A mask often traps not only heat, but also moisture behind it and inside the nose. Excessive moisture coating the lining of the nose can decrease the sensitivity of air passing through the nasal cavity. This can create a sensation of decreased breathing or congestion in the nose.
Negative Pressure
Breathing in air against a filter or mask can cause negative pressure in the nose. This causes expansion of tissues and increased nasal congestion which results in the perception of decreased ability to breathe through the nose.
Allergies
People already with allergies may feel they are worse with mask use. Pollens & other allergens can build up on the surface of masks. Make sure you are not allergic to the fibers or materials in your mask. Clean your mask or change out your mask after each use.
Structural Issues
Pre-existing medical issues such as a deviated septum, nasal polyps, large adenoid and tonsil tissues may also contribute to difficulty breathing through a face mask.
