How much fluid do you lose on a flight?

Cabin humidity on a plane is typically 10-20%, so travellers lose roughly 465ml of fluid per hour on a flight. A 7-hour flight can mean 3+ litres of total body water loss through breathing and skin evaporation.

Does a cruise cause dehydration?

Yes. Sun, wind and alcohol on deck can quietly dehydrate cruise passengers. Estimate around 120ml of fluid loss per hour on a cruise, more on active shore-excursion days.

How do I calculate travel fluid loss?

Pick your travel scenario (flight, cruise, sun/beach, city break or adventure), enter the duration in hours and minutes, and the calculator multiplies the time by the typical fluid-loss rate for that activity.

Why travel dehydrates you

Flights: cabin humidity drops to 10-20%, accelerating respiratory and skin water loss.
Cruises: sun, wind and deck time increase sweat and insensible losses.
Hot climates: higher sweat rates can double normal fluid needs.
Altitude / adventure: faster breathing and dry mountain air increase fluid loss.
