1. The Impact of Cabin Altitude
Does flying at high altitudes make you tired? Yes, it does, and the primary culprit is cabin altitude. While airplanes fly at altitudes of 30,000 to 40,000 feet, the cabin is pressurized to a much lower altitude, typically around 6,000 to 8,000 feet. This is still significantly higher than most people are used to, and it can have several physiological effects. According to research from Embry-Riddle Aeronautical University, even moderate altitude exposure can lead to decreased oxygen saturation in the blood, causing fatigue, headache, and even mild cognitive impairment.

1.1. Understanding Cabin Pressurization
Cabin pressurization is essential for passenger survival at high altitudes. As the aircraft ascends, the pressure inside the cabin is gradually reduced to minimize the stress on the aircraft’s hull. The difference between the pressure inside and outside the aircraft is known as differential pressure. Aircraft engineers carefully design and regulate the cabin altitude to balance structural integrity with passenger comfort.
1.2. Physiological Effects of High Cabin Altitude
At a cabin altitude of 8,000 feet, the partial pressure of oxygen is lower than at sea level. This means that each breath you take contains less oxygen. Your body compensates by increasing your heart rate and breathing rate to deliver more oxygen to your tissues. However, this can lead to fatigue, especially on long flights. People with pre-existing respiratory or cardiovascular conditions may experience more pronounced symptoms. The reduced air pressure can also cause gases in your body to expand, leading to bloating and discomfort.
1.3. Altitude Sickness and Air Travel
Although most passengers don’t experience full-blown altitude sickness, the subtle effects of high cabin altitude can mimic some of the symptoms, such as headache, fatigue, and shortness of breath. Individuals who are more susceptible to altitude sickness, such as those who live at sea level or have respiratory issues, may find flying more tiring. Moreover, according to the International Air Transport Association (IATA), passengers with certain medical conditions should consult their doctor before flying to mitigate any potential risks associated with cabin altitude.
1.4. Counteracting the Effects of Cabin Altitude
There are several things you can do to mitigate the effects of cabin altitude. Staying hydrated is crucial, as dehydration can exacerbate the symptoms of altitude sickness. Avoid alcohol and caffeine, as they can both contribute to dehydration. Consider using nasal saline spray to keep your nasal passages moist, as dry air can make breathing more difficult. If you have a pre-existing respiratory condition, talk to your doctor about whether you need supplemental oxygen during the flight.
2. Dehydration and Air Travel Fatigue
Why does airplane air make you so thirsty? The extremely low humidity in airplane cabins is a significant contributor to dehydration and, consequently, to air travel fatigue. The air circulated in airplanes comes from outside at high altitudes, where the humidity is typically only around 1% to 2%. This air is then heated and circulated throughout the cabin, creating an extremely dry environment. As a result, passengers lose moisture through their skin and breath at a much faster rate than they would on the ground.
