Introduction
Traveling on long-haul flights presents several challenges to the body, including dehydration, bloating, and energy depletion. Airplane cabins have low humidity levels, increasing fluid loss, while limited in-flight food options often lack essential nutrients. Proper preparation before the flight can help mitigate these issues and keep you feeling your best throughout your journey.
Below are smart hydration and nutrition tips to follow before a long flight to maintain energy, digestion, and overall well-being.

1. Hydration Strategies Before a Long Flight
A. Increase Water Intake 24 Hours Before Departure
- Drink plenty of water in the day leading up to your flight.
- Aim for at least 2-3 liters of water to ensure proper hydration.
- Spread out water intake rather than drinking large amounts at once.
B. Choose the Right Beverages
- Opt for herbal teas, infused water, or coconut water for extra hydration.
- Avoid excessive caffeine and alcohol, as they contribute to dehydration.
- Green tea or lemon water can help maintain hydration while providing antioxidants.
C. Use Electrolyte Supplements
- Electrolyte powders or tablets help retain fluids and prevent dehydration.
- Look for options with sodium, potassium, and magnesium to replenish essential minerals.
- Coconut water is a natural electrolyte-rich drink for pre-flight hydration.
D. Eat Hydrating Foods
- Consume fruits and vegetables with high water content, such as cucumbers, watermelon, oranges, and celery.
- Soups and broths can also contribute to hydration.
- Avoid excessive salt, which can lead to water retention and bloating.
2. Nutrition Tips for Long-Flight Preparation
A. Prioritize Balanced Meals

- Whole-grain crackers with hummus or nut butter
- Avoid sugary and ultra-processed snacks that can cause energy crashes.
C. Maintain Gut Health
- Probiotic supplements or fermented foods (yogurt, kefir, kimchi) support digestion.
