Best Practices For Staying Hydrated On A Plane
Flying can be a dehydrating experience, but with some smart planning and preparation, you can keep yourself properly hydrated throughout your journey.
Here are some best practices to help you stay hydrated on a plane:
Discovering Alternative Hydration Options On Flights
Bring an empty water bottle:
Instead of relying on the small cups of water provided by the flight attendants, carry an empty water bottle with you.
Once you pass through security, you can fill it up at a water fountain or ask the flight attendants to fill it for you during the flight.
Opt for herbal tea:
Herbal tea bags are a great alternative to plain water. They offer hydration with the added benefit of delicious flavors and therapeutic properties.
Simply bring your favorite herbal tea bags on board, ask for hot water from the flight attendants, and enjoy a soothing cup of tea.
Pack electrolyte tablets:
Dehydration not only leads to thirst but also causes an imbalance in your electrolyte levels. To replenish these essential minerals, consider packing electrolyte tablets or powder.
Add them to your water or tea, and you’ll have a refreshing drink that helps you rehydrate and keeps your body functioning optimally.
Snack on hydrating fruits:
Along with staying hydrated, it’s important to consume foods that have a high water content. Snacking on hydrating fruits like watermelon, grapes, and cucumber can provide an additional source of hydration and keep you feeling refreshed.
Tips For Replenishing Water Supplies During Layovers And Long Flights
- Explore airport water stations: Many airports now have designated water stations where you can refill your water bottle. Take advantage of these amenities during layovers to ensure you have enough water for the duration of your flight.
- Bring a backup water bottle: If you have a long flight or several connecting flights, it’s always a good idea to carry an extra water bottle with you. This ensures you have access to water even if the flight attendants are busy or the water service is limited.
- Drink water frequently: During a flight, the dry cabin air can cause rapid dehydration. Make it a priority to drink water frequently, even if you don’t feel thirsty. Sip on small amounts throughout the flight to stay hydrated.
- Avoid alcohol and caffeine: While it may be tempting to enjoy a cocktail or a cup of coffee during your flight, alcohol and caffeine can further dehydrate your body. Opt for water, herbal tea, or electrolyte drinks instead.
By following these best practices, you can prioritize your hydration and enjoy a comfortable flight without feeling parched.
Remember, staying hydrated is not only important for your overall well-being but also contributes to a more pleasant travel experience.
