is it good to drink electrolytes before flying

When you have a flight coming up, it’s natural to feel anxious about the effects of flying on your body. The air inside the airplane is dry, and the altitude can lead to dehydration. This can be especially concerning for individuals who are prone to dehydration or those with certain medical conditions. One remedy that many people turn to is drinking electrolytes before flying. But is it actually good for you? Let’s delve into the topic and find out.

The Importance of Electrolytes

Before we dive into whether it’s good to drink electrolytes before flying, let’s first understand the importance of electrolytes. Electrolytes are minerals in your body that have an electric charge. They play a crucial role in maintaining the balance of fluids and the pH level in your body. The most common electrolytes in the human body are sodium, potassium, calcium, and magnesium. These minerals are essential for various bodily functions, including muscle contractions, nerve function, and the regulation of blood pressure.

Dehydration and Air Travel

Dehydration is a common issue during air travel. The humidity inside an airplane can drop as low as 10-20%, which is drier than most deserts. This dry air can lead to increased water loss from the body, potentially causing dehydration. Additionally, the reduced air pressure at higher altitudes can further exacerbate the effects of dehydration. For those who are already prone to dehydration, such as individuals with diabetes or those taking diuretic medications, the effects of flying can be even more pronounced.

The Case for Electrolyte Drinks

Now, let’s address the question at hand: is it good to drink electrolytes before flying? Many people swear by electrolyte drinks as a way to combat dehydration during air travel. These drinks typically contain a mixture of electrolytes, along with water and sugar. The idea is that consuming electrolytes before or during a flight can help replenish the minerals lost through sweat and urine, and aid in maintaining the body’s fluid balance.

Consideration for Sugar Content

While electrolyte drinks can be beneficial in replenishing lost minerals, it’s important to consider their sugar content. Many commercial electrolyte drinks contain added sugars, which can lead to a sudden spike in blood sugar levels. This can be problematic for individuals with diabetes or those trying to manage their weight. Therefore, it’s crucial to read the labels carefully and opt for sugar-free or low-sugar electrolyte drinks if you choose to consume them before flying.

Alternative Ways to Stay Hydrated

Drinking electrolytes before flying isn’t the only way to combat dehydration during air travel. There are several alternative methods that can help you stay hydrated and comfortable during your flight:

1. Drink Plenty of Water

Water is the best way to stay hydrated, so make sure to drink plenty of it before, during, and after your flight. Aim to consume at least 8 ounces of water for every hour in the air.

2. Avoid Alcohol and Caffeine

Alcoholic and caffeinated beverages can contribute to dehydration, so it’s best to avoid them before and during your flight.

3. Use a Humidifier

If you’re concerned about the dry air inside the airplane, consider using a personal humidifier to add moisture to the air around you.

4. Eat Water-Rich Foods

Fruits and vegetables with high water content, such as cucumber, watermelon, and oranges, can help keep you hydrated during your flight.

Drinking electrolytes before flying can be beneficial in maintaining your body’s fluid balance and combating the effects of dehydration during air travel. However, it’s important to choose electrolyte drinks that are low in sugar and to consider alternative methods of staying hydrated. Remember to drink plenty of water, avoid alcohol and caffeine, and consume water-rich foods to keep yourself comfortable and hydrated during your flight.


1. Can I drink electrolyte drinks before flying if I have diabetes?

It’s best to consult with your healthcare provider before consuming electrolyte drinks, especially if you have diabetes. Opt for sugar-free or low-sugar options and monitor your blood sugar levels carefully.

2. Are electrolyte drinks safe for children to consume before flying?

Electrolyte drinks can be safe for children, but it’s important to choose products that are specifically formulated for their age group. Always read the labels and consult with your child’s pediatrician if you have any concerns.

3. How soon before flying should I drink electrolytes?

It’s generally a good idea to start hydrating well before your flight. Consuming electrolytes a few hours before flying can help prepare your body for the effects of air travel.

4. Can I bring electrolyte drinks in my carry-on luggage?

Most electrolyte drinks are considered liquid items, so they are subject to the 3-1-1 rule for carry-on luggage. Ensure that the bottles are within the size limits and place them in a clear, resealable plastic bag for security screening.

5. Are homemade electrolyte drinks a good alternative to commercial ones?

Homemade electrolyte drinks can be a good alternative, especially if you want to control the ingredients and sugar content. You can make your own by mixing water, salt, and a small amount of sweetener, such as honey or agave nectar.
