How to Stay Hydrated While Traveling by Plane

Air travel can be exciting and convenient, allowing us to explore new destinations and connect with loved ones. However, flying can also take a toll on our bodies, particularly when it comes to hydration. The low humidity levels and recycled air in the airplane cabin can lead to dehydration, leaving passengers feeling fatigued and uncomfortable. Staying hydrated during air travel is essential for maintaining our well-being and ensuring a pleasant journey. In this blog, we will explore the importance of hydration while flying, the factors that contribute to dehydration on planes, practical tips to stay hydrated, and the benefits of incorporating proper hydration into your travel routine.

The Importance of Hydration While Flying

Hydration is crucial for our bodies to function optimally, and it becomes even more critical during air travel. The dry cabin air on airplanes can lead to increased water loss through respiration and skin evaporation, making it easier for passengers to become dehydrated. Dehydration can cause symptoms such as dry skin, fatigue, headaches, and dizziness. Moreover, dehydration can worsen jet lag and make the travel experience more uncomfortable overall.

Factors Contributing to Dehydration on Planes

  1. Low Humidity: The humidity level in airplane cabins can be as low as 10-20%, which is much drier than most indoor environments. This dry air can quickly lead to moisture loss from the body.
  1. Recycled Air: The air in the airplane cabin is often recycled, which can lead to a buildup of contaminants and reduce oxygen levels, contributing to dehydration.
  1. Altitude: Flying at high altitudes can increase fluid loss due to changes in air pressure and decreased oxygen levels.
  1. Limited Access to Water: Passengers may not have easy access to water during certain phases of the flight, such as takeoff and landing.

Practical Tips to Stay Hydrated While Flying


Drink Plenty of Water

Begin hydrating well before your flight and continue to drink water throughout the journey. Aim to drink at least eight ounces of water every hour while in the air.

Avoid Alcohol and Caffeine

Alcohol and caffeine can contribute to dehydration, so it’s best to avoid them during your flight. Stick to water or herbal teas instead.

Bring a Refillable Water Bottle

Carry a refillable water bottle with you and ask the flight attendants to fill it up whenever you need a drink. Having a water bottle handy encourages you to drink more frequently.

Use Hydrating Skincare Products

Moisturize your skin with hydrating skincare products to prevent it from becoming dry and uncomfortable during the flight.

Opt for Hydrating Snacks

Choose hydrating snacks like fruits and vegetables instead of salty or processed foods, which can contribute to dehydration.

Use Saline Nasal Spray

Using a saline nasal spray can help keep your nasal passages moist and prevent dryness during the flight.

Avoid Overconsumption of Diuretics

Try to avoid foods and beverages that act as diuretics, such as alcohol, caffeine, and salty snacks, as they can increase fluid loss.

Moisturize Your Eyes

If you wear contact lenses, consider using eye drops or opt for glasses during the flight to prevent eye dryness and discomfort.

Limit Airplane Alcohol

If you choose to have a drink during the flight, limit your alcohol intake to avoid further dehydration.

Eat Water-Rich Foods

Consume water-rich foods like watermelon, cucumber, and oranges to supplement your water intake.


Benefits of Incorporating Proper Hydration into Your Travel Routine


Reduced Fatigue and Jet Lag

Staying hydrated can help reduce fatigue and minimize the effects of jet lag, allowing you to feel more energized upon arrival.

Enhanced Immune Function

Proper hydration supports a healthy immune system, which is especially important when traveling and being exposed to new environments.

Improved Skin Health

Hydration helps keep your skin moisturized, reducing the risk of dryness and irritation often experienced during air travel.

Better Cognitive Function

Proper hydration supports optimal brain function, helping you stay alert and focused during your journey.

Reduced Discomfort

Staying hydrated can prevent common symptoms of dehydration, such as headaches and dizziness, making your travel experience more comfortable.
