Why Airplanes Are a Nasal Danger Zone (And What You Can Do About It)

You’ve packed your bags, passed security, and found your seat. But while you're focused on your destination, your immune system is suddenly under attack—and the culprit is all around you. Airplane cabins are a notorious breeding ground for airborne germs. But the real problem? Your nose may not be ready to defend you.

Dry Cabin Air = Weak Nasal Defenses

Commercial flights keep cabin humidity below 20%—that’s drier than most deserts. This dryness affects your nasal mucosa, the moist lining inside your nose that traps and filters pathogens.

When this layer dries out, it cracks. That means bacteria, viruses, and allergens can bypass your natural filters and go straight into your body.

Quick Tip: Drink water, avoid alcohol or coffee before boarding, and breathe through your nose—not your mouth.

The Invisible Risk: Shared Air

Even with air filtration systems, cabin air is recycled. When someone coughs or sneezes, micro-particles stay suspended in the air longer than you think. If your nasal passages are already dry and vulnerable, it’s a perfect storm.
