Hydration for Travel: Why Flying Drains You Faster Than You Think
Ever feel exhausted after a flight—even short ones?
That’s dehydration.
Why Flights Dehydrate You
Cabin humidity:
10–20% (extremely low)
This accelerates:
- Fluid loss
- Electrolyte depletion
Why Bottled Water Isn’t Enough
Most travel hydration relies on:
- Low-mineral bottled water
This doesn’t replace what you lose
