Why do you get so dehydrated when flying?

Flying can be an exhilarating experience, but it often leaves us feeling parched and dehydrated. This seemingly rapid dehydration can be attributed to several factors, mainly the low humidity levels and increased altitude inside the airplane cabin. Let’s delve deeper into why this happens and how it affects our bodies.

When inside an airplane cabin, the humidity levels can drop significantly, sometimes as low as 20%. To put this into perspective, the average humidity in our homes generally ranges from 30% to 50%. Such low humidity means that moisture is rapidly drawn from our bodies, causing our skin, lips, and eyes to feel dry and uncomfortable. Additionally, the dry air can also cause problems for individuals with respiratory issues such as asthma or allergies.

Altitude is another crucial factor that contributes to dehydration during flights. As the aircraft ascends to higher altitudes, the air pressure decreases, resulting in a lower boiling point for water. This lower boiling point makes it harder for our bodies to retain water, causing us to breathe out more moisture than we normally would. Coupled with the dry cabin air, this leads to increased water loss, making it crucial to rehydrate regularly while flying.

FAQs about dehydration during flying:

1. How can dehydration affect our bodies?

Dehydration can have various adverse effects on our bodies, including dry skin, headache, fatigue, and even worsened jet lag symptoms. It can also impair our cognitive functions, making it difficult to concentrate or think clearly. Staying hydrated is vital to avoiding these symptoms and ensuring we feel our best during and after a flight.

2. Can drinking water before the flight prevent dehydration?

While drinking water before a flight is undoubtedly beneficial, it may not entirely prevent dehydration. The dry cabin air and high altitude can still cause moisture loss within our bodies. Therefore, it’s essential to continue drinking water throughout the flight to maintain hydration levels.

3. Does alcohol consumption contribute to dehydration while flying?

Yes, alcohol consumption can exacerbate dehydration while flying. Alcohol is a diuretic, meaning it increases urine production and subsequently leads to fluid loss. Combined with the dry air in the cabin, drinking alcohol can further dehydrate the body. It’s advisable to limit alcohol intake and opt for water or non-alcoholic beverages instead.

4. Are there any dietary recommendations to prevent dehydration during flights?

Maintaining a well-balanced diet plays a crucial role in hydration. Foods with high water content, such as fruits and vegetables, can help replenish lost fluids. It’s also recommended to avoid salty snacks, as they can increase fluid loss. Remember to drink plenty of water, even when the flight attendants aren’t offering beverages.

5. Can dehydration on flights worsen the effects of jet lag?

Dehydration during flights can indeed worsen the symptoms of jet lag. Fatigue, dizziness, and headaches associated with jet lag can be amplified when the body is dehydrated. To mitigate these effects, it’s important to hydrate before, during, and after the flight and ensure adequate rest.

6. Does the duration of the flight impact dehydration levels?

The duration of the flight can impact dehydration levels to some extent. Longer flights may increase the likelihood of dehydration due to the extended exposure to dry air and low humidity. However, it’s important to stay hydrated regardless of the flight duration to minimize any adverse effects.

7. Are there any specific measures to prevent dehydration during long-haul flights?

During long-haul flights, staying hydrated is even more crucial. In addition to drinking plenty of water, it’s advisable to avoid excessive caffeine and alcohol consumption. Using moisturizers to combat dry skin and nasal sprays to ease any discomfort related to dry air can also be helpful.

8. Can dehydration during flights affect individuals with existing medical conditions?

Dehydration during flights can be particularly challenging for individuals with certain medical conditions, such as diabetes or kidney problems. It’s crucial for such individuals to consult their healthcare provider for specific recommendations and additional precautions to take while flying.

9. Do infants and children have a higher risk of dehydration during flights?

Infants and children are generally more susceptible to dehydration, and flying can further increase this risk. It’s important to pay extra attention to their hydration needs, making sure they consume sufficient fluids before, during, and after the flight. Breastfeeding or bottle-feeding infants during takeoff and landing can also help alleviate discomfort and maintain hydration.

10. Can using a humidifier or moisturizing sprays help combat dehydration during flights?

Using a personal humidifier or moisturizing sprays can indeed provide some relief from the dry cabin air. These can help increase the humidity immediately surrounding you, reducing the rapid moisture loss from your skin and respiratory system. However, it’s essential to check the airline’s regulations and restrictions before using any personal devices on the flight.

11. Are there any notable differences in dehydration levels between different types of aircraft?

While the overall dehydration risk remains the same across different aircraft, factors such as cabin size, humidity control systems, and individual airline policies can impact the comfort levels and potential dehydration experienced during a flight. Passengers should prioritize hydration regardless of the aircraft type.

12. Can dehydration during flying affect individuals with sensitive skin?

Individuals with sensitive skin may experience heightened discomfort and dryness during flights due to the low humidity levels. It’s advisable for such individuals to use adequate moisturizers and hydrating products before and during the flight to protect and nourish their skin.

In conclusion, the combination of low humidity levels and high altitude in airplane cabins leads to rapid dehydration during flights. Staying hydrated by drinking water regularly, avoiding excessive alcohol and caffeine consumption, and considering additional measures such as using moisturizers can help alleviate the discomfort and health issues associated with flying. Taking proactive steps to combat dehydration ensures a more comfortable and enjoyable journey.
