Introduction

Altitude sickness, also known as acute mountain sickness (AMS), is a condition that can occur when ascending to high altitudes. It is characterized by symptoms such as headache, nausea, dizziness, and fatigue. However, when flying in an airplane, most people do not experience altitude sickness. This raises the question: why don’t you get altitude sickness in a plane?

Pressurized Cabin

One of the main reasons why passengers don’t experience altitude sickness in an airplane is due to the pressurized cabin. Commercial aircraft are equipped with pressurization systems that regulate the air pressure inside the cabin. These systems mimic the air pressure experienced at lower altitudes, making it more comfortable for passengers.

Pressurization Process: The pressurization process involves compressing outside air and supplying it to the cabin. This ensures that the pressure inside the cabin remains at a level that allows passengers to breathe comfortably. The cabin altitude is typically maintained at around 6,000 to 8,000 feet, even when the aircraft is flying at much higher altitudes.

Altitude and Oxygen Levels

Altitude sickness is primarily caused by the decrease in oxygen levels at higher altitudes. As you ascend to higher elevations, the air becomes thinner, resulting in a lower concentration of oxygen molecules. This decrease in oxygen can lead to the symptoms associated with altitude sickness.

In an airplane, the pressurized cabin helps maintain a higher concentration of oxygen compared to the actual altitude outside the aircraft. This ensures that passengers receive an adequate supply of oxygen, reducing the risk of altitude sickness.

Gradual Ascent

Another factor that contributes to the absence of altitude sickness in planes is the gradual ascent. When climbing to high altitudes on foot or by other means, the body needs time to acclimatize to the change in altitude. Rapid ascents can increase the risk of altitude sickness.

In contrast, airplanes ascend gradually, allowing passengers’ bodies to adjust to the changing altitude more easily. This gradual ascent minimizes the chances of experiencing altitude sickness.

Humidity and Temperature Control

Airplanes also control humidity and temperature levels inside the cabin, which can further contribute to the absence of altitude sickness. At high altitudes, the air is typically dry and cold, which can exacerbate the symptoms of altitude sickness.

By maintaining a controlled environment, airplanes ensure that the humidity and temperature inside the cabin are comfortable for passengers. This helps prevent the drying of mucous membranes and reduces the likelihood of experiencing altitude-related discomfort.

Conclusion

In conclusion, the pressurized cabin, maintained oxygen levels, gradual ascent, and controlled environment in airplanes all contribute to the absence of altitude sickness. These factors work together to create a comfortable and safe flying experience for passengers, even at high altitudes.

While altitude sickness can be a concern when traveling to high elevations by other means, flying in an airplane provides a unique environment that minimizes the risk of experiencing these symptoms.
