I’ve heard there’s a link between catching colds and flying. Am I more likely to get sick if I travel on a plane?
Yes! According to a 2004 study published in the Journal of Environmental Health Research, plane travelers are up to 113 times more likely to catch a virus than their ground-bound counterparts.
Why is this? The study put forth a series of potential culprits: fatigue, low outside air replacement, dry cabin air, and proximity of people to one another in a small space. While all of these may play a part, the researchers found that an airplane cabin’s low humidity — which weakens humans’ defenses against infection — is likely the greatest factor in passengers’ heightened susceptibility to infection.
Use these preventive tactics to keep from catching a cold the next time you catch a flight: Get plenty of sleep before your trip, stay well-hydrated, wash your hands often, and avoid touching your face or mouth. Boost your immunity pre-flight by supplementing your diet with medicinal herbs, such as astragalus, garlic, ginger and ginseng, and medicinal mushrooms, such as maitake, reishi and shiitake.
