Does flying make altitude sickness worse?

When it comes to altitude sickness, flying can indeed exacerbate the symptoms. Altitude sickness, also known as acute mountain sickness (AMS), is a condition that occurs when you ascend to higher altitudes too quickly, often above 8,000 feet (2,400 meters). It is caused by the decreased availability of oxygen at higher elevations, resulting in various symptoms such as headache, nausea, fatigue, dizziness, and difficulty sleeping.

The pressurization in aircraft cabins is generally set to mimic the conditions at lower elevations, typically around 6,000 to 8,000 feet (1,800 to 2,400 meters) above sea level. This can help alleviate some of the symptoms of altitude sickness during the flight. However, it’s important to note that the cabin altitude can still be higher than what most individuals are used to at ground level.

During the ascent in an aircraft, the cabin altitude gradually increases. As a result, if you have recently been at high altitudes or are already experiencing symptoms of altitude sickness, flying can make it worse. The rapid ascent in an airplane, coupled with the reduced oxygen levels, can put additional strain on your body and potentially intensify the symptoms of altitude sickness. Therefore, individuals with a history of altitude sickness or those who are prone to it should take precautionary measures before flying to higher altitudes.

FAQs about altitude sickness and flying

1. What are the common symptoms of altitude sickness?

Altitude sickness can manifest in a variety of symptoms, including headache, nausea, dizziness, fatigue, loss of appetite, insomnia, and shortness of breath.

2. How long does it take for altitude sickness to develop?

Altitude sickness can occur within a few hours of ascending to higher altitudes, but it typically takes around 12 to 24 hours for symptoms to fully develop.

3. Can I prevent altitude sickness when flying?

While you can’t completely prevent altitude sickness, you can take measures to reduce the risk and severity of symptoms. Drinking plenty of fluids, avoiding alcohol and caffeine, and ascending slowly can help. Additionally, medication such as acetazolamide may be prescribed by a healthcare professional to aid in acclimatization.

4. Are there certain individuals more prone to altitude sickness?

Some individuals are more susceptible to altitude sickness than others. Factors that can increase the risk include a previous history of altitude sickness, rapid ascent, physical exertion at high altitudes, and certain medical conditions.

5. Is there a specific altitude at which altitude sickness occurs?

Altitude sickness can occur at altitudes above 8,000 feet (2,400 meters), but the severity can vary from person to person. Some individuals may experience symptoms at lower altitudes, while others may not be affected until reaching higher elevations.

6. What is the best way to acclimatize to high altitudes before flying?

If you know you will be flying to a high-altitude destination, it is beneficial to acclimatize yourself gradually. Arriving a day or two early to allow your body time to adjust can help reduce the risk and severity of altitude sickness.

7. Can children experience altitude sickness when flying?

Yes, children can be affected by altitude sickness as well. However, it is important to note that symptoms and their severity can vary among individuals, regardless of age.

8. What should I do if I start experiencing symptoms of altitude sickness during a flight?

If you start experiencing symptoms of altitude sickness during a flight, inform the cabin crew or seek medical assistance if necessary. They can provide you with oxygen, offer appropriate advice, and ensure your well-being during the flight.

9. Does flying increase the risk of developing severe altitude sickness?

Flying itself does not necessarily increase the risk of developing severe altitude sickness. However, if you are already experiencing symptoms or have a predisposition to altitude sickness, the rapid ascent in an aircraft can worsen the condition.

10. Can I fly immediately after a mountain trek without experiencing altitude sickness?

While it is possible to fly immediately after a mountain trek without experiencing altitude sickness, it is not recommended. Allowing your body time to acclimatize after descending from higher altitudes is crucial in reducing the risk and severity of altitude sickness. It is generally advised to wait at least 24 to 48 hours before flying.

11. Can I experience altitude sickness when flying to destinations at lower elevations?

Altitude sickness is more commonly associated with higher altitudes. However, some individuals may still experience mild symptoms when flying to destinations at lower elevations, especially if they ascended rapidly or have a predisposition to altitude sickness.

12. Can altitude sickness be life-threatening during a flight?

In most cases, altitude sickness is not life-threatening and resolves on its own with adequate rest and acclimatization. However, severe forms of altitude sickness, such as high altitude pulmonary or cerebral edema, can be potentially life-threatening and require immediate medical attention. It is important to recognize the symptoms and seek appropriate help if needed.
