Why do I wake up with a dry or stuffy nose in the morning?

Your humidity settings may be too low and may need to be increased (refer to the manual on how to adjust humidity settings). Make sure your equipment is being cleaned regularly as un-cleaned or contaminated equipment may lead to sinus infections. Should you suffer from allergies, you may need to consult your physician regarding possibly prescribing a nasal spray to help decrease nasal inflammation/stuffy nose.
