If you’ve ever searched for an international travel wellness guide, it’s probably because you’ve stepped off a long-haul flight feeling wrecked — dehydrated, jet lagged, foggy, and already behind on your trip. International travel looks glamorous, but in reality it tests your body and mind in ways most people never expect.
I learned this firsthand. Over the course of my career, I flew more than 500 long-haul international flights to Korea, Japan, China, and Europe. My peers called me a “professional jet setter,” but the truth was far from glamorous. I’d cross the Pacific for a one-day meeting, fly to Hamburg the next day for a trade show, then be back in the States two days later for another round of work. And in Europe, the culture of long business dinners — often stretching five or more hours — pushed my endurance even further.
That’s when I realized: without a plan, international travel will drain you. Over 20 years, I refined and upgraded a simple wellness program until it became a system that fit me perfectly. The truth is, everyone needs to experiment and build their own version — because no two bodies handle travel exactly the same.
People used to hate traveling with me because I never seemed to get tired. While others could barely stay awake, I stayed sharp because my program worked. That’s exactly why I’m writing this blog: so you can take what I learned from decades on the road, adapt it to yourself, and make your trips healthier, smoother, and a whole lot easier.
What You’ll Learn in This Blog
In this guide, I’ll share the exact system that worked for me:
How I managed to sleep before, during, and after flights
Why eating well (not dieting) kept me fueled and sane

Whether you’re traveling for business or for fun, these strategies will help you land clear-headed, energized, and ready to go.

Most people imagine international travel as champagne in business class, glossy airport lounges, and Instagram-worthy arrivals. The truth is very different. Long flights are punishing — no matter how many times you’ve done them. After 500+ long-hauls, I can tell you that the human body was never designed to sit in recycled air at 35,000 feet for 10–14 hours straight.
Here’s what really happens: your body dehydrates rapidly because cabin humidity is lower than the Sahara desert. Your sleep schedule is shredded across time zones, and even if you manage to doze off, it’s rarely restorative. Digestion slows down, leading to bloating and discomfort, while circulation suffers from hours of sitting still. And then there’s the mental side — fatigue, irritability, brain fog, and the jet lag that doesn’t just hit when you land but lingers for days.
I’ve seen colleagues arrive looking sharp only to collapse halfway through a meeting, and I’ve watched seasoned travelers get knocked out by the smallest cold because their immune systems were run down. For me, migraines and muscle spasms were a constant threat. Without preparation, you step off the plane already in deficit — and if your trip is for business, that deficit can cost you the whole purpose of your travel.
That’s why I built my international travel wellness guide into my own program. Not because I wanted to look organized, but because it was the only way to survive and stay functional through back-to-back meetings, client dinners, and the relentless pace of global travel.

Sleep was always non-negotiable. The night before a trip, in the airplane, or at a hotel, I made sure I was ready to rest. My trick was to work out hard (especially cardio) before a long flight. It knocked me out on the plane and reset my rhythm. I used supplements as usual, avoided caffeine in the evenings or during flights, and slept as much as possible in the air.
When it came to food, I threw out any diet mentality. International business travel burns through your energy. I focused on high-protein, high-quality meals both before and during trips. Breakfast was always a must. Sometimes I’d adapt to local food — other times I’d play it safe and eat at the hotel. Either way, the rule was simple: eat well, enjoy food, and treat it as one of the joys of life. I’m a foodie, so trying new dishes kept me energized and happy. A few extra pounds? Worth it.
I never traveled without a few key supports:
Echinacea was my most valued supplement — I believe it was my shield against viruses and travel bugs. Alka-Seltzer also saved me countless times, especially when alcohol and heavy food were part of late-night customer dinners.
Exercise was another cornerstone. Cardio before travel was my secret weapon for inflight sleep. During trips, even 15 minutes of floor exercises in a hotel room — push-ups, squats, planks — made a difference. And when I was too exhausted to hit the gym, a hot sauna or massage worked as a substitute.
I also made time for mental resets. International travel is stressful, so I always prepped logistics in advance — airport rides, hotels, routes — to minimize chaos. During the trip, I used small timeouts: meditation, breathing exercises, or even a quick nap.
And finally, gut health. Foreign food, heavy dinners, and alcohol can throw anyone off. My solution was simple: Alka-Seltzer before bed, and sometimes even during long dinners. It kept my gut steady and gave me the stamina to make it through nights that lasted five hours or more.

Airplane cabins are as dry as deserts, and it shows on your skin and lips. I always kept a face spray in reach to refresh throughout the flight. Mijung, with her flight attendant beauty background, taught me the “mist → mask → moisturizer” ritual — that one’s her department. My personal essential was lip balm. She convinced me to use LANEIGE Lip Sleeping Mask, and it kept my lips from cracking during flights. Honestly, travel and flying are the only times I ever use lip balm — but it works.
Supplements were also timed by destination. I never just took them randomly. Vitamin C and greens in the morning, echinacea in the evening, magnesium at night. That rhythm helped me adjust to time zones faster.
Finally, I had a seat-back pocket strategy. I loaded it with exactly what I needed: electrolytes, supplements, spray, and sleep mask. Everything within reach, no rummaging. That tiny adjustment turned a cramped seat into a personal wellness zone.
Not every hotel has a gym, and sometimes you land too late to use it. I kept simple workouts I could do anywhere — squats, push-ups, planks, stretch bands. Even a short session kept me sane and boosted circulation.
Another secret weapon was Alka-Seltzer. Most people wait until they feel bad. I drank it during long dinners, and it not only calmed my gut but kept me awake. Taking another before bed gave me a head start on recovery.
And last, my mental rituals. Chaos is part of international business travel. What kept me grounded was carving out micro-breaks: 5 minutes of meditation in a lounge, breathing exercises while boarding, or grabbing a 20-minute nap whenever I could. These small pauses added up and gave me energy when everyone else was fading.
After 500+ long-haul international flights, I can tell you this: international travel is not about glamour, it’s about endurance. You can either let the flights own you, or you can build a system that keeps you sharp.
My international travel wellness guide wasn’t about chasing comfort — it was about survival. Sleep, food, supplements, hydration, gut care, exercise, and mental resets — those were the pillars that let me land ready to work, instead of collapsing.
But here’s the real lesson: you need to create a system that works for you. The routines I perfected over 20 years won’t look exactly the same for everyone. Experiment, adjust, and refine until you find your rhythm.
Because at the end of the day, travel wellness isn’t one-size-fits-all — it’s about building a program that lets you arrive energized, clear-headed, and ready for what matters most.
