Flying is hard on the body in subtle ways. Dry air, long periods of sitting, disrupted sleep, questionable food choices, and less-than-ideal hygiene conditions all add up. The goal is not perfection or a midair wellness ritual. It is to arrive feeling functional, clear-headed, and reasonably human.
Knowing how to stay healthy while flying comes down to a few small, intentional choices before and during your flight.
These are a few tips for approaching in-flight wellness without turning it into a production.
Hydration Really Matters If You Want To Stay Healthy While Flying
I’ve said it before. I’ll say it again. Flying is dehydrating. Dehydration is hell on your body. Proper hydration is foundational to staying healthy while flying.
Start increasing your water intake at least one day before you travel, not just once you’re seated. On the flight itself, aim to sip consistently for the duration of the flight rather than chugging all at once.
Room-temperature or cool water is often easier to sip consistently than very hot or ice-cold drinks, which can make steady hydration more manageable mid-flight. For extra points on long-haul flights or travel days that involve heat, movement, or alcohol, adding a clean electrolyte supplement once a day can also help support hydration without overdoing it.
This is not about being virtuous. It’s about arriving without a headache, dry skin, or that strange hollowed-out feeling dehydration brings.
Skin Health: Do Less, Protect More
Flying accelerates transepidermal water loss (the natural evaporation of moisture from the skin) thanks to low cabin humidity and recycled air.
The best strategy is preventative, not reactive.
Before boarding, apply a rich, occlusive moisturizer to seal in hydration. Think creams and balms, not lightweight gels. This creates a barrier that helps your skin retain moisture throughout the flight.
My (perhaps slightly controversial) take: Skip elaborate skincare mid-flight.
Sheet masks and multi-step routines may be the influencer-approved move, but let’s approach this with a little dignified rationality.
- Masks and facial creams can disrupt the skin barrier. At altitude, your goal is to protect that barrier as much as possible to reduce moisture loss and irritation. Overdoing products mid-flight can increase sensitivity, redness, stinging, and even flare-ups for conditions like eczema.
- Your hands are never truly clean on a plane. Repeatedly touching your face, especially to apply products, quickly becomes counterproductive.
- And yes, I’ll say it: sheet masks and eye patches belong at home or in a treatment room. Planes are neither. This is my professional opinion.
That said, if it’s been a particularly grueling travel day and my face genuinely needs a refresh, I’ll keep things discreet and minimal:
- Thoroughly wash and sanitize my hands (including nails)
- A wipe-down with a gentle biodegradable cleansing cloth (these are excellent)
- A quick swipe of a trusted lightweight moisturizer I know won’t clog pores, just enough to keep my skin comfortable until we’re back in reasonable humidity
Sunscreen Is Not Optional on a Plane
Always wear sunscreen when flying. Sounds weird. But hear me out.
UV exposure increases at higher altitudes because there is less atmospheric filtering. Airplane windows block most UVB rays but allow some UVA to pass through, which contributes to skin aging and long-term skin cancer risk. This is especially relevant for pilots and flight crew with repeated exposure over time, but passengers seated near windows on long daytime flights can also receive measurable UVA exposure.
Apply a broad-spectrum SPF 30 or higher before boarding, regardless of season or destination.
You may also find yourself standing in an outdoor line for a tarmac bus, a taxi, or a train, or sitting in the sun by a terminal window at some point during your travel day.
Even if you are not seated by a window, sunscreen remains a smart baseline habit for travel days. While airplane windows are the primary source of in-flight UV exposure, broad-spectrum SPF protects against ultraviolet radiation in general, which is the meaningful concern at altitude. Some mineral formulas also offer limited protection against visible light, but ultraviolet exposure is the main reason sunscreen matters when flying.
Low effort. High payoff. Sunscreen always.
Movement and Circulation
Long periods of sitting affect circulation, stiffness, and overall energy levels. You do not need to turn the aisle into a yoga runway. Please don’t be that person. Small movements are enough.
- Ankle circles
- Gentle seated stretches
- Short walks up and down the aisle
- A few discreet stretches in the galley or exit row area while waiting for the restroom
All help keep blood moving and reduce that heavy, swollen feeling in your legs and feet.
If you tend to deal with lower back strain in economy seating, slightly elevating your feet can make a meaningful difference. Just a few inches of lift improves hip angle and reduces pressure on the lumbar spine. I use a compact foot hammock that attaches to the tray table and supports my feet without taking up space. I discovered this trick a couple of years ago and it makes long flights noticeably more comfortable.
Compression socks are also worth packing. They support circulation even when you’re not moving and can noticeably reduce swelling and fatigue upon arrival.
I have worn the same pairs on nearly every long-haul flight for the past 12+ years. I used to deal with swollen feet and ankles in flight. Now it’s a non-issue. I bring one pair for the outbound flight and pack a second for the return. Hot tip: After washing, hang them to dry so the elastic doesn’t wear out. They will last for years.
Sleep: Support It, Don’t Force It
Sleep strategy is one of the most overlooked parts of how to stay healthy while flying long distances.
If possible, start adjusting your sleep and meal times a few days before departure, especially when crossing more than three time zones. Even small shifts can reduce jet lag.
Full disclosure. I hate this advice. It’s completely unrealistic for my lifestyle, and I’ve never understood how people manage it. Still, it works for some, so it’s worth mentioning in case it works for you.
If pre-adjusting isn’t realistic, (ahem) plan your sleep on the flight based on your destination’s time zone, sleeping or staying awake accordingly.
To make in-flight rest easier:
- Bring a comfortable eye mask
- Use a functional neck rest (I use this one)
- Use noise-canceling headphones or earplugs (a MUST)
- Choose a window seat for fewer interruptions and a sturdy place to lean
Avoid caffeine in the two hours before takeoff and limit alcohol. Both interfere with sleep quality and contribute to dehydration, which makes jet lag worse.
I’ll make another unpopular but hard-learned suggestion here: skip the heavy sleeping pills.
You rarely have a full 7-8+ uninterrupted hours on a plane for a prescription-grade sleeping pill to fully wear off. That can leave you groggy while navigating customs lines, baggage claim, unfamiliar airports, and local transportation. It is not the state you want to be in.
If you truly need support, consider a gentler over-the-counter option. I personally prefer something mild, like Unisom, that helps take the edge off without completely sedating you.
Sleep does not need to be perfect to be helpful. Sometimes a few hours of mental shutdown is enough to get you through.
Eat Better, Not Necessarily Less
Flying can be tough on digestion. Cabin pressure, vibration, and changes in blood flow can lead to bloating, gas, and nausea.
The goal is nourishing and gentle, not restrictive.
Choose snacks that travel well and support steady energy:
- Nuts
- Fruit
- Protein bars
- Simple wraps
Avoid heavy, rich, overly salty meals and carbonated drinks before and during the flight. At the same time, skipping food entirely can backfire, leaving you depleted and more jet-lagged when you arrive.
When on a flight that includes meal service, I try to opt for the low-sodium meal choice when I can. (You typically have to request this ahead of time, when booking your ticket) I find that it helps reduce swelling in my hands and feet and keeps me feeling a bit less saturated upon landing.
Balance matters.
Support Your Immune System and Your Nervous System
Airports and planes test both immunity and patience.
Simple supports can help:
- A clean vitamin C + zinc supplement the day before and day of travel
- Prioritizing sleep pre-flight
- Frequent hand washing
- Staying hydrated
Equally important is nervous system regulation. Travel stress accumulates quickly and the body responds.
When you can:
- Listen to calming music to limit noise overload
- Practice patience with fellow travelers. It’s stressful for everyone
- Listen to a short guided meditation if you are a nervous flyer
- Limit pre-travel alcohol to keep your wits and dignity intact
- Remember to breathe
Feeling calm is a form of wellness, too.
The Takeaway
Travel doesn’t need to feel punishing, especially when you know how to stay healthy while flying.
A few intentional choices: hydration, protection, movement, rest, nourishment, and your mindset can dramatically change how you experience flying and how you feel when you arrive.
You don’t need a perfect routine. You just need one that works.
