Air travel exposes the body to conditions that increase the risk of dehydration. For optimal human health and comfort, ideal humidity levels range between 30 percent and 60 percent. However, humidity levels inside most aircraft cabins drop to between 10 percent and 20 percent at cruising altitude. Combined with lower oxygen pressure, this environment accelerates fluid loss from the body.
Water evaporates more quickly from your skin and lungs as you breathe. Many travellers also drink less water intentionally to avoid frequent bathroom visits, or simply forget due to busy schedules. These factors can quickly lead to dehydration, affecting energy levels, comfort, focus, and overall health.
Proper hydration is essential to help you enjoy your trip, maintain productivity, and support your body during and after your flight.
Drink Water Regularly Throughout the Flight
Consistent drinking water intake is the most effective way to prevent dehydration during air travel. You should drink more water than usual to compensate for the dry cabin environment. A good guideline is approximately 250 millilitres per hour, which equals about one standard airline cup.
Setting a reminder on your phone or using a hydration app can help you maintain regular intake. It is easy to forget to drink water when watching movies, working, or sleeping during a flight.
You can also bring an empty reusable water bottle in your carry on luggage. While liquids cannot pass through security screening, most airports provide refill stations after screening, allowing you to access clean drinking water before boarding.
Limit Dehydrating Beverages
Caffeinated drinks, alcohol, and sugary beverages can increase fluid loss and contribute to dehydration. Coffee and alcohol act as mild diuretics, which increase urine production and fluid loss.
This does not mean you must avoid them completely. If you drink coffee, balance it by drinking a glass of water alongside it. You can also choose herbal tea as a more hydrating alternative.
Prioritising water supports better hydration, improves comfort, and helps maintain your energy levels throughout your journey.
Choose Hydrating Foods
Hydration comes not only from drinking water but also from the foods you eat. Fruits and vegetables with high water content contribute to fluid intake while supporting nutrition and health.
Good options include watermelon, oranges, strawberries, cucumbers, lettuce, and salads. These foods also provide essential vitamins and minerals that support overall wellbeing during travel.
Avoid salty snacks, which can increase thirst and contribute to dehydration.
Pack Electrolytes for Long Flights
Electrolytes are essential minerals such as sodium, potassium, and magnesium that help regulate fluid balance, muscle function, and nerve activity. During flights, especially long haul travel, electrolyte supplements can help maintain hydration more effectively.
Electrolyte powders or tablets are easy to carry and can be added to water when needed. They help your body absorb and retain fluids more efficiently, supporting hydration and overall balance.
Electrolytes should complement regular drinking water, not replace it.
Move Around and Stay Active
Movement helps circulation, reduces stiffness, and supports overall comfort during long flights. Take opportunities to stand, stretch, and walk around the cabin when safe to do so.
This is also a good time to refill your water bottle and maintain hydration. Regular movement supports your body and reduces travel fatigue.
Protect Your Skin From Dry Air
Low cabin humidity affects not only internal hydration but also your skin. Dry air can cause irritation, dryness, and discomfort, especially during long haul flights.
Using a moisturiser, facial spray, or hydrating mask can help protect your skin. While this does not replace drinking water, it supports overall comfort and helps reduce the effects of dry cabin air.
