9. Don’t Sit the Entire Flight
Airplane travel puts you at a higher risk of getting deep vein thrombosis. It’s a type of blood clot in the legs, and somebody coined it economy-class syndrome.
You should walk around a bit — in your shoes, of course — and stretch your legs to get the blood flowing. Also, don’t wear tight clothes that restrict blood flow.
8. Don’t Wear Contact Lenses
The dry air in the cabin can irritate your eyes if you wear contact lenses. Also, if you love to sleep when you fly and are unaccustomed to sleeping in your contacts, that will irritate your eyes even more. Don’t make flying more uncomfortable than it already is, and wear your glasses instead.
7. Don’t Turn Off the Air Vent
Experts say the overhead air should be medium to high to blow away germs before they get into your personal space to harm you. So, put on a sweater or use a blanket to cover if you feel chilly.
