Showing 7 causes
Pet dander
Air conditioners could pull dander from the floor and furniture.
Dry nasal passages
Air conditioners remove moisture from the air; this lack of humidity dries out the nasal lining. This makes it sensitive and prone to the sneezing reflex.
Dust and dust mite accumulation
AC vents and filters could collect dust over time; when the unit is turned on, these particles are circulated through the room and inhaled.
Vasomotor rhinitis
Triggered by the sudden change in temperature and humidity when stepping out from warm outdoor air to the cool, dry air produced by an air conditioning system.
Mold and mildew exposure
Moisture buildup inside air conditioning coils or drip pans could lead to mold growth that release spores into the air whenever the system runs.
Cold-stimulus rhinitis
Physical shock of cold air hitting the damp skin or nasal membranes from chilled air could trigger a rapid sneezing fit.
Chemical sensitivities
AC units or ductwork could have scents from cleaning agents or synthetic materials.
