According to the Centers for Disease Control (CDC), the air inside planes has anywhere from 10 to 20 percent humidity, which can dry out mucous membranes and make people more susceptible to germs.

"Alcoholic and caffeinated drinks should be followed with water or fruit juice to rehydrate because they are diuretics and can cause water loss," advise Ray Fillmore Garman, MD, MPH, and Susan Spengler, MD, both associate professors with the Department of Preventive Medicine at the University of Kentucky. Sipping on water assists with immune function -- and in some cases even helps with jet lag. For longer, international trips pack electrolyte-friendly snacks like GU Energy Chomps, a banana, nuts, or a small bag of fortified cereal to keep drowsiness at bay.
