How Your Bedroom Air Quality Affects Sleep

The Bedroom Is Your Highest-Exposure Room

Seven to nine hours per night, every night, breathing air within a few inches of your mattress and pillow. If CO2 accumulates because the door is closed and ventilation is poor, sleep quality suffers and you wake up groggy. If dust mite allergens in the mattress trigger congestion, you mouth-breathe and wake with a dry throat. If humidity is too low, airways dry out. If it is too high, mold and dust mites thrive. The bedroom is where air quality problems produce their most concentrated exposure.

Small Changes, Measurable Impact

A door undercut for ventilation, allergen encasements on the mattress, a humidity target of 30 to 50%, and adequate HVAC filtration are the foundation of good bedroom air. The assessment evaluates which of these factors need attention in your specific situation.
