There's something about airplanes that just screams germs. The relatively tight space, the recycled air, and the person sitting next to you who never learned to cover his mouth when he or she coughs. Here are a few simple tips to avoid germs on an airplane:
Before you board stay hydrated. This will keep your respiratory tract moist, which gives you more protection against germs
Travel with nose protection. Use a saline nasal solution or nasal mist to keep your nasal passages moist, which effectively boosts your body's own germ-flushing action
Wash your hands after touching the seat cushion
Use an alcohol-based hand wipe before you use the tray table
Clean your hands after handling the In-flight entertainment controls
Avoid touching surfaces in the airplane bathroom. Use the paper toilet-seat cover (or place toilet paper over the seat), and try a non-touch technique when washing your hands: Use a paper towel to turn on the faucet, wash with soap and hot water, and use a fresh paper towel to turn off the faucet and to open the restroom door.
