Why do I feel so awful after flying?

Grounded and Grumpy: Why Flying Leaves You Feeling So Awful

That feeling of utter exhaustion after a flight – the throbbing headache, the foggy brain, the overwhelming desire to collapse into bed – is a near-universal experience for travelers. We often chalk it up to jet lag, but there’s more to it than just a disrupted sleep schedule. In fact, a cocktail of physiological factors conspires to leave you feeling less than your best, starting the moment you buckle your seatbelt.

One of the biggest culprits is the air pressure inside the cabin. While airplanes are pressurized, they’re not pressurized to sea level. The typical cabin altitude is equivalent to being around 6,000 to 8,000 feet above sea level. This reduced pressure means less oxygen is available in each breath you take. Think of it as a mild, sustained climb up a mountain, even though you’re sitting still.

This lower oxygen intake triggers a chain reaction. Your body has to work harder to deliver oxygen to your cells, leading to fatigue and lightheadedness. Some individuals, particularly those with pre-existing respiratory conditions, may experience more pronounced symptoms, even feeling nauseous. The feeling is akin to being slightly altitude sick, a condition that can manifest with similar complaints.

But it’s not just the air pressure. The dry air circulating in the cabin further exacerbates the situation. This dryness dehydrates your body, leading to headaches, dry skin, and a scratchy throat. Dehydration can also thicken mucus, making you more susceptible to catching airborne illnesses that thrive in the enclosed environment.

So, what can you do to combat these airborne ailments? The good news is that with a little preparation and self-care, you can significantly minimize the negative effects of flying. Here are a few strategies:

• Hydrate, hydrate, hydrate: Drink plenty of water before, during, and after your flight. Avoid excessive alcohol and caffeinated beverages, as they can contribute to dehydration.
• Move around: Get up and walk around the cabin every hour or so to improve circulation and combat stiffness. Simple stretches can also help.
• Choose your snacks wisely: Opt for healthy snacks like fruits, vegetables, and nuts. Avoid processed foods that can leave you feeling sluggish.
• Consider oxygen supplementation (if needed): For individuals with respiratory conditions, consulting with a doctor about supplemental oxygen during flight might be beneficial.
• Rest and recover: Give yourself time to adjust to your new surroundings after landing. Avoid scheduling strenuous activities immediately upon arrival.

Flying may never be a truly effortless experience, but understanding the physiological challenges involved can empower you to take proactive steps to mitigate their impact. By prioritizing hydration, movement, and rest, you can arrive at your destination feeling refreshed and ready to embrace your adventure, instead of grounded and grumpy.
