Does flying make you dehydrated?
Flying can indeed lead to dehydration, and this is primarily due to the low humidity levels in aircraft cabins. When we’re up in the air, the air we breathe is significantly drier than what we’re used to on the ground. The humidity in an airplane cabin can drop to as low as 10-20%, compared to the average humidity of around 40-60% in most homes. This dry air can cause our bodies to lose moisture more rapidly, leading to dehydration.
In addition to the dry air, there are other factors that can contribute to dehydration during a flight. One of these factors is the decreased cabin pressure at higher altitudes. As the pressure decreases, the gases in our bodies expand, including the gases in our tissues. This can lead to increased fluid loss, as the expanded gases in our body try to equalize with the lower pressure outside.
Furthermore, flying can also cause dehydration because of the limited access to fluids during a flight. We all know that drinking water is essential for staying hydrated, but it can be challenging to drink enough water on a plane. The small cups of water offered during meal service may not be enough to keep up with our hydration needs. Additionally, many people tend to avoid drinking too much water on flights to avoid frequent trips to the restroom. As a result, they end up not drinking enough water, which further contributes to dehydration.
How can I prevent dehydration while flying?
1. Stay hydrated: Drink plenty of water before, during, and after your flight. It’s recommended to drink at least 8 ounces of water for every hour you’re in the air. Consider bringing an empty reusable water bottle through security and filling it up once you’re past the checkpoint.
2. Avoid diuretics: Limit your consumption of alcohol and caffeine during the flight, as these can dehydrate you further. Stick to water or herbal tea instead.
3. Use moisturizers: Apply a hydrating moisturizer and lip balm to prevent your skin and lips from drying out.
4. Avoid excessive alcohol: As tempting as that cocktail or glass of wine might be, alcohol can contribute to dehydration. It’s best to avoid it or limit your consumption during the flight.
5. Use a humidifier: Consider using a personal humidifier or a hydrating nasal spray to add moisture to the air around you.
6. Avoid salty snacks: Snacks that are high in sodium can make you thirstier and, therefore, more prone to dehydration. Opt for healthier options like fresh fruits or granola bars instead.
7. Take short walks: Moving around the cabin and stretching your legs can help improve blood circulation and prevent fluid retention.
8. Avoid tight clothing: Wear loose, comfortable clothing that allows your body to breathe and helps regulate your temperature.
By following these tips, you can minimize the effects of dehydration and make your flight a more comfortable and enjoyable experience.
FAQs about dehydration during flights:
1. Can dehydration during a flight cause health issues?
Dehydration during a flight can potentially lead to health issues such as dry skin, dry eyes, fatigue, headache, and even dizziness. It’s important to stay hydrated to prevent these symptoms.
2. Does drinking alcohol help with hydration during a flight?
Contrary to popular belief, drinking alcohol during a flight can actually dehydrate you further. It’s best to avoid or limit alcohol consumption and opt for water instead.
3. Are certain individuals more susceptible to dehydration during flights?
Yes, certain individuals such as the elderly, people with medical conditions, and those taking medications can be more susceptible to dehydration during flights. They should take extra precautions and consult with their healthcare provider if necessary.
4. Can using a moisturizing lotion help prevent dehydration?
Using a moisturizing lotion can help prevent the drying effects of low humidity in the aircraft cabin, but it won’t directly hydrate you from within. It’s still essential to drink plenty of water.
5. Can flying dehydrate your skin?
Yes, the low humidity in the cabin can contribute to dry skin. Applying moisturizers, especially ones designed for air travel, can help combat this.
6. Can dehydration during flights affect your immune system?
Dehydration during flights can weaken your immune system, making you more susceptible to illnesses. Staying hydrated is crucial to support your body’s immune function.
7. Can dehydration worsen jet lag symptoms?
Dehydration can exacerbate the symptoms of jet lag, such as fatigue and headaches. By staying hydrated, you can potentially alleviate some of these symptoms.
8. Can dehydration during a flight affect your cognitive function?
Yes, studies have shown that even mild dehydration can impair cognitive function, affecting your ability to concentrate and think clearly. Staying hydrated is important for optimal brain function.
9. Does the duration of the flight affect dehydration levels?
Longer flights can increase the risk of dehydration due to the extended time spent in a dry, pressurized cabin. It’s important to pay extra attention to your hydration levels during lengthier journeys.
10. Can dehydration during flights lead to deep vein thrombosis (DVT)?
While dehydration alone may not directly cause deep vein thrombosis, it can contribute to the risk factors associated with DVT, such as blood thickening. Staying hydrated and moving around the cabin can help reduce the risk.
11. Can certain foods help prevent dehydration during flights?
Foods with high water content, such as fruits and vegetables, can contribute to your hydration. Snacking on hydrating foods like cucumber, watermelon, or celery sticks can be beneficial.
12. Is dehydration less common on shorter flights?
Dehydration can still occur on shorter flights, especially if they involve high altitudes and low humidity. It’s important to stay hydrated regardless of the flight duration.
