If airline travel is in your forecast, you’ll want to arm yourself with a nasal cleansing spray to protect from the dry air when in flight.
The low humidity can dry out nasal passages causing discomfort, especially during takeoff and landing.
A 2004 edition of the Journal of Environmental Health Research reported that the higher incidence of colds reported by recent aircraft passengers may be due to a decline in their ability to resist infection while flying.
“Your nose has a thin layer of mucus that actually helps traps germs and irritants. The in-flight air dries out that protective layer making you more susceptible to discomfort or even colds and viruses,” said Ed Neuzil, Ph.D., ARNP and owner of The Allergy, Sinus & Asthma Family Health Center in Lady Lake, Fla. “Cleansing your nasal passages of debris or germs with a moisturizing nasal spray helps maintain the natural protectants your body provides.”
Nasal sprays with herbal ingredients such as menthol or eucalyptol may also help open up your sinuses and alleviate some of the pressure you feel during altitude changes.
