Why do I feel unwell after flying?

The Jet Lag of Germs: Why You Feel Under the Weather After Flying

That post-flight slump isn’t just jet lag; it’s often a cocktail of factors stemming from the unique environment of air travel. While the romance of soaring through the clouds persists, the reality for many passengers is a less glamorous arrival, marked by sniffles, headaches, and general malaise. So why do we often feel unwell after flying?

The primary culprit is the air itself. Airplanes are notorious for recirculating air, meaning the same air is filtered and reused throughout the flight. While filters remove many particles, they don’t eliminate all viruses and bacteria. This creates a confined space where germs can spread easily amongst passengers in close proximity. Coughing, sneezing, and even simple breathing near others increases the likelihood of transmission, especially for contagious illnesses circulating at the time of travel. Imagine a petri dish at 30,000 feet, and you’re starting to get the picture.

Beyond the germ factor, the air inside the cabin is significantly drier than typical ambient air. This low humidity dehydrates the mucous membranes in your nose, throat, and sinuses. These membranes are your body’s first line of defense against invading pathogens. When they’re dry and compromised, they’re less effective at trapping and eliminating viruses and bacteria, leaving you more vulnerable to infection. This dryness also contributes to the post-flight discomfort many experience, manifesting as sore throats, dry coughs, and even headaches.

The effects are amplified by several other travel-related factors. The stress of travel itself can weaken the immune system, making you more susceptible to illness. Changes in altitude and pressure can also impact your body’s functions, potentially exacerbating existing conditions or contributing to feelings of fatigue and disorientation. Lack of sleep during the flight, irregular meal times, and dehydration from limited fluid intake further compound the problem.

So, what can you do to mitigate these risks? Staying well-hydrated before, during, and after your flight is crucial. Consider bringing a saline nasal spray to moisten your nasal passages and help combat dryness. Washing your hands frequently, avoiding touching your face, and using hand sanitizer are simple yet effective ways to minimize the spread of germs. Getting sufficient sleep before your flight and prioritizing healthy eating can also boost your immune system and improve your overall resilience to the stresses of air travel. Finally, if you are feeling unwell, consider wearing a mask to protect fellow passengers.

While the thrill of air travel remains undeniable, understanding the factors contributing to post-flight illness allows us to take proactive measures to minimize their impact. By prioritizing hygiene, hydration, and well-being, we can strive for a smoother, healthier journey – both during the flight and upon arrival.
