CPAP safely treats sleep apnea, but occasionally causes side effects.
CPAP users sometimes complain of cold, dry, painful or stuffy noses. Other side effects from CPAP are associated with the mask rubbing on the nose or a poorly fitting mask causing air to blow into the eyes.
Tips to prevent some of these side effects:
Use a heated humidifier, which warms and humidifies the air blowing into your nose.
Purchase some inexpensive over-the-counter nasal washes to help prevent nasal irritation and congestion.
Change the size or style of your mask.
