The Post-Flight Blues: Why We Feel Sick After Flying

The thrill of arriving at a new destination can quickly be overshadowed by a nagging feeling of malaise. Many travelers experience a lingering “jet lag” even on short flights, but the discomfort can extend beyond fatigue, manifesting as a sore throat, stuffy nose, and overall feeling of being under the weather. What’s behind this post-flight blues, and how can we minimize its effects?

The culprit isn’t always just a case of being “out of sorts” due to time zone changes. The airplane environment itself can contribute to a weakened immune system and physical discomfort. Here’s how:

• Stress and Immune Suppression: The anticipation of travel, airport crowds, and potential delays can trigger a stress response in our bodies. This can lead to a weakened immune system, leaving us more vulnerable to viruses and bacteria that are prevalent in enclosed spaces like airplanes.
• Dry Cabin Air: Airplane cabins are notoriously dry, with humidity levels often below 20%, significantly lower than the ideal 40-60% range. This dry air can strip moisture from the delicate mucosal linings in our nose, throat, and airways, making them more susceptible to irritations and infections.
• Circulation and Blood Clots: Long flights, especially in economy class, can restrict blood flow to the legs, increasing the risk of blood clots. While not directly related to feeling sick, this can lead to discomfort and potentially serious health issues.

Tips to Minimize Post-Flight Discomfort:

• Stay Hydrated: Drinking plenty of water before, during, and after the flight is crucial. Avoid alcohol and caffeine, which can further dehydrate you.
• Moisturize: Use a saline nasal spray to keep your nasal passages hydrated. Additionally, use a moisturizer for your skin to combat the drying effects of the cabin air.
• Move Around: Get up and walk around the cabin every hour or so to improve circulation and prevent blood clots.
• Manage Stress: Practice relaxation techniques like deep breathing or meditation to reduce stress and boost your immune system.
• Prioritize Sleep: Adjust your sleep schedule gradually in the days leading up to your flight, and try to sleep on the plane.

Beyond the Flight:

Even after landing, it’s important to continue focusing on your health. Get plenty of rest, eat healthy foods, and engage in moderate exercise to support your immune system. If you experience persistent symptoms, consult a doctor.

While the feeling of being “sick” after flying can be frustrating, understanding its root causes empowers us to take proactive measures and minimize its impact. By following these tips, we can travel with confidence, minimize the post-flight blues, and maximize our enjoyment of our destination.
