Why Staying Hydrated on Flights Reduces Jet Lag
Awesome Travel Tip #54 • Safety
Flying is hard on the body, and dehydration is one of the biggest reasons travelers feel awful when they land.
Quick Answer
Drink water consistently on flights. Hydration reduces jet lag, fatigue, headaches, and that drained feeling after landing.
The Tip
Airplane cabins are extremely dry, which causes dehydration faster than most people realize. Drink water regularly throughout the flight and avoid excessive caffeine or alcohol.
Using a refillable water bottle makes it easier to stay hydrated without relying on infrequent drink service.
Why Hydration Affects Jet Lag
Dehydration worsens fatigue, brain fog, muscle soreness, and headaches. Staying hydrated helps your body adjust to time zone changes more smoothly and recover faster after long flights.
How to Stay Hydrated While Flying
- Drink water every hour, even if you don’t feel thirsty.
- Limit alcohol and caffeine, which increase dehydration.
- Bring an empty bottle through security and refill.
- Eat hydrating foods when available.
- Start hydrating before boarding.
Mistakes to Avoid
- Don’t rely on thirst alone.
- Don’t overdo alcohol.
- Don’t skip water on overnight flights.
- Don’t assume coffee replaces hydration.
