Water, that is. This is one tip nearly all of our experts were quick to mention. "Hydrate, hydrate, hydrate," says Jerry Bishop, a commercial pilot who's flown mostly trans-Atlantic routes for the past 18 years. "It's really just common sense, but you don't realize how much flying takes out of you." San Diego-based travel writer Cynthia Dial says she tries to drink a quart of water for every four hours she's in the air. Bobby Laurie, a former flight attendant whose nationally syndicated travel talk show "The Jet Set" debuts next year, says he always travels with his own water bottle, whether purchased in the airport or a refillable one from home (most airports have filtered water fountains), to hold him over until beverage service.
You’re probably not drinking enough, especially if you’re traveling through hot, humid countries. If you can drink the tap water, make the most of it and get your two litres of water a day. If not, help the environment by bringing a Steripen along, rather than buying dozens of plastic bottles of water — a Steripen kills more than 99.9% of harmful microorganisms, including giardia, bacteria, viruses, and protozoa, making tap water safe to drink.
Here’s a confession: I gained around 20 pounds over my first few years of travel, mostly thanks to eating out for every single meal. While it can be tempting to treat yourself to junk food, and Pringles and Oreos will fuel your every travel day, resolve to have at least a few days every now and then when you go for the healthier option. Your body and mind will thank you for it. Aim to cut out the rice, bread, and beer to keep your calorie intake low if you’re feeling as though you’re gaining too much weight on the road.
