Unhealthy mistakes you make when you fly

Everyone loves a vacation. The plane ride that usually happens on the way to said vacation, however, isn't always as fun. From the long airport security lines to the array of funky smells that hit your nose within seconds of boarding, I'd be lying if I said flying was one of my favorite parts about traveling. And since I almost always end up with a terrible cold any time I come remotely close to an airport, I often wonder if maybe, just maybe, there's a way to be more health-conscious about flying. My usual routine of getting lost in an audiobook while curled up in my window seat, waiting for the plane to land, just doesn't seem to be cutting it.

That's why I took to the experts to find out what unhealthy habits most of us are guilty of when flying. Here's what they had to say.

Skipping out on water

I'll be the first to admit that I'm not always good about drinking water, especially when I'm traveling. In fact, one of the only parts of an airplane ride I look forward to is ordering a Ginger Ale because it is one of the few times I drink anything resembling soda. But as refreshing as this little ritual has been for me, it isn't the healthiest of choices according to Toby Amidor, MS, RD nutrition expert and author of The Greek Yogurt Kitchen: More Than 130 Delicious, Healthy Recipes For Every Meal of the Day. "It is of utmost importance to hydrate during (and after) the flight," she told me in an interview. "Flying can easily dehydrate you because the humidity in the cabin is much lower than usual."

Besides seriously drying out your skin and making you feel fatigued, letting your body become dehydrated can also make you susceptible to some less-than-pleasant health issues. "Harsh cabin air often dries up the mucous membranes in the ears, nose, and mouth, which can leave you more susceptible to infection," NYC cardiovascular surgeon Dr. David Greuner explained to me via email. "Make sure you're drinking enough water to offset the dry conditions by sipping until your urine becomes light in color."

Relying on airport food


From oversized pastries to candy bars and soda, airports are a land mine of unhealthy food options that can wreak havoc on our bodies, making us feel even more lethargic and cranky while in the air. "When flying folks usually opt for the non-perishable carbs like chips, crackers, muffins, and other such dry foods," Amidor told me. "This can easily get someone off track of their healthy eating plan and often can lead to overeating on days that you're flying. Together with not drinking enough water, it can really throw your whole body off where you just don't feel well." Instead, she suggests scoping out the airport food court for things like fruits, vegetables, dairy, and lean protein.

Dr. Greuner even suggests taking your planning a step further by pre-packing your own food. "I'll typically bring hummus packs and grain crackers, vegetables that won't perish easily, homemade trail mix, and a protein bar to hold me over until my next meal," he said.

Not only are these overall healthier choices, but they'll also help you avoid that run-down and sluggish feeling that so often comes from indulging in too many processed foods.

Ignoring germs

If you're anything like me, you can practically guarantee you'll catch a cold within days of stepping off an airplane. In fact, recent research conducted by CompareTravelInsurance.com.au claims that we're nearly 100 times more likely to catch a cold during a flight, thanks to being cramped in close quarters in a virtually humidity-free zone (conditions where cold and flu viruses thrive).

To avoid catching these germs, Dr. Greuner suggests packing plenty of antibacterial wipes or gel. "The second you get on the flight, consider wiping the tray table, seats, and buttons around your seat to kill any lingering germs left behind from other passengers," he said.

He also suggests bringing along vitamin C to boost your immune system during the flight. "I'll often take vitamin C a few days before I plan on traveling to prepare my system for any germs it might come into contact with in the air," he said.

Staying seated the entire flight

Okay, so getting up to use the airplane bathroom isn't exactly tempting. But even if you do try to avoid those tiny lavatories like the plague, Dr. Shawn Tsuda, a board-certified general surgeon at miVIP Surgery Centers, says it's important to get up out of your seat periodically throughout the duration of your flight. "Sitting for long periods can predispose you to blood clots in your legs," he explained to me. "These can be potentially deadly."

Dr. Greuner agreed, saying, "No matter what the mode of transportation, sitting motionless for long periods may put some travelers at an increased risk for Deep Vein Thrombosis, a blood disorder resulting from the formation of a blood clot (thrombus) inside a deep vein of the leg, commonly located in the calf or thigh." And with 2 million DVT cases diagnosed in the United States each year, Dr. Greuner notes it is the third leading cardiovascular disease behind heart attack and stroke.

"Your blood can't circulate efficiently without a little help from your muscles," added naturopathic physician Dr. Taryn Forrelli of OLLY Vitamins. "If you don't want to walk off the plane with swollen ankles, you need to engage your muscles by moving your body."

Falling asleep in a bad position

While catching up on sleep could be a productive way to kill time while in the air, dozing off in certain positions can put major stress on your body. "Not bracing your neck during a flight is a common mistake," Carolyn Dean, MD, ND a sleep and nutrition expert, and author of The Magnesium Miracle told me via email.

"Brace your neck with a curved travel pillow, you will sleep better and avoid neck ache and a misaligned neck, which will result in pain, decreased circulation, and poor sleep," she said. "I always take a flight pillow with me."
