If you're prone to sinus problems, find dry airplane air irritating, or feel like you often get upper respiratory illnesses while travelling, try this simple trick.
Buy, at any drugstore, the sterile saline cartridges to squirt up into the nose. Use them about every 2 hours (you'll need some Kleenex also). They'll keep your mucous membranes moist, which allows the immune system scavenger cells in your nose to function better.
You may want to use these saline cartridges in desert or other dry climates as well.
