Flying can be one dehydrating experience. You know the feeling: you’ve just landed at your destination after a long flight, your skin feels dry and you’re itching for a glass of water.

So what’s the deal? Dr. Oz says it’s all about the lack of humidity due to the high altitude. This results in your nasal passages getting dried out and cracking, which can lead to bacteria or a virus getting in.

“When you fly in the air, you’re really flying at 30,000 feet but you body thinks you’re at 7,000 or 8,000 feet. It’s dry up there,” he tells Rachael. “It’s 10 percent humidity as opposed to the normal, which is 30 or 40 percent.”

To combat dehydration, Dr. Oz has three helpful ways to keep all that moisture in.


Dr. Oz suggests keeping a face mist nearby to spray when you feel yourself drying out. Just spritz a few times during your flight and you’ll be good to go.


To stay hydrated, Dr. Oz says passengers should drink eight ounces of water for every hour they’re on a flight. If you don’t like plane water or forgot to grab a bottle of water after getting past TSA, he suggests packing coconut powder to make coconut water. This will give you a balance of electrolytes, which are essential to staying hydrated.


While tempting, Dr. Oz says you’ll want to avoid sugar, caffeine and alcohol when flying. “Caffeine and alcohol are a problem because they fool your body to go to the bathroom more than you need to,” he explains. Instead, choose herbal teas. They’ll keep you relaxed and you’ll fall asleep more comfortably.
