How to Stay Healthy on Long Flights and Layovers
Long-haul travel takes a toll on your body. A few simple habits during flights and layovers help you arrive feeling far more human.
Staying comfortable on long flights and layovers is mostly about hydration, movement and rest: drink water and go easy on alcohol and caffeine, walk and stretch on long layovers, and use the wait to reset rather than slump. A shower or a short walk does more than another coffee. For body-clock tips, see using layovers to beat jet lag.
- Hydrate; go easy on alcohol and caffeine.
- Move and stretch — use the layover to walk.
- A shower or spa resets you better than caffeine.
- Manage your body clock — see beating jet lag.
Hydration and movement
Cabin air is very dry, so drink water regularly and go easy on alcohol and excess caffeine. Move often — walk the cabin, stretch, and use a long layover to walk the terminal rather than sitting the whole time. This reduces stiffness and supports circulation on long journeys.
- Drink water, limit alcohol
- Walk and stretch regularly
- Use layovers to move
Sleep, light and jet lag
Align sleep with your destination's time zone as early as you can, and use natural light to help your body clock adjust. On overnight layovers, a real sleep in a pod or lounge beats fragmented dozing. An eye mask, earplugs and a consistent wind-down routine all help.
Hygiene and comfort
Wash or sanitise hands before eating, and freshen up mid-journey — a layover shower is a genuine reset. Wear comfortable clothing and supportive shoes, and consider compression socks on very long flights to reduce swelling and fatigue.
Hydration, movement, rest
Cabin air is dry, so drink water steadily and limit alcohol and excess caffeine. On a long layover, walk the terminal and stretch rather than sitting the whole time — it helps circulation and energy. A shower or short spa stop is a genuine reset before the next leg.
Use the layover well
Treat the wait as recovery time: eat something reasonable, hydrate, move, and rest if it's an overnight (see red-eye tips). If you're crossing time zones, start nudging your body clock now — our jet lag guide explains how. None of this is medical advice — listen to your body and seek care if you feel unwell.

| Rest | Nap on long/overnight waits | Skipping sleep before a red-eye |
