The desert has nothing on the typical airplane cabin when it comes to dry air. The World Health Organization (WHO) reports that humidity in airplane cabins is usually less than 20 percent. For comparison, the Environmental Protection Agency (EPA) recommends that houses be kept between 30 and 50 percent humidity. Low airplane humidity is, for now, a fact of air travel—but it’s also an increasingly recognized part of jet lag, susceptibility to illness, and that general feeling of malaise that comes with flying.
Some newer planes, like Airbus A350s and Boeing 787 Dreamliners, maintain higher humidity levels, but on most flights, it’s up to you to combat low humidity. In doing so, you can stay healthier and more comfortable, and you’ll likely also rebound faster from the effects of jet lag.
