Flying
Do you travel frequently for work or pleasure? Your sinuses can get worse from it.
In-flight air pressure reductions can lead to a build-up of pressure in the head, which can aggravate cold symptoms by clogging air passages and sinuses, thereby leading to dry nose. During takeoff and landing, this is especially problematic.
Use a decongestant nasal drop or inhaler prior to takeoff to keep your sinuses clear if you have a history of sinus infections or congestion but are unable to miss your flight.
Overuse of Nasal Products
While it’s true that nasal decongestant sprays reduce congestion by narrowing the blood vessels in the nose, you shouldn’t take over-the-counter nasal sprays for an extended period of time since they can exacerbate symptoms if not used as prescribed.
Rebound nasal congestion is the term for the problem that occurs when you use sprays for an extended period of time and lose sensitivity to their effects, causing your nose to swell again.
Those who use over-the-counter nasal sprays to relieve cold symptoms should cease using them after four or five days because extended usage of these sprays can result in reliance and lead to dry nose.
