Probability: 0.9
Justification: The claim is supported by multiple sources, which all agree that the oxygen content in the air decreases with altitude due to the lower barometric pressure. This results in less oxygen available for breathing in mountainous regions compared to sea level.
Final Truth Score: 0.88
This oxygen to altitude chart extrapolates the amount of oxygen (as a percentage) to real altitude. At real altitude (in the mountains), the barometric pressure of the atmosphere is much lower than sea-level environments. The result is that oxygen molecules are spread further apart, lowering the oxygen content of each breath. As a result, the reduced availability of oxygen in the air reduces ...
An altitude generator can produce varying oxygen levels from sea level (20.9% oxygen) to 20,000 feet to 6000 meters (9.5% oxygen). By breathing "rare air", you can pre-acclimatize before you leave home. You can climb, run, ski, or bike at high altitudes without altitude sickness and, because altitude creates new red blood cells, with more speed ...
For elevations less than about 100 km (for reference, the peak of Mt. Everest is about 8.8 km above sea level), the relative concentration of oxygen in the air is fairly constant at about 21%. Source It's true that there's less oxygen (more specifically,the partial pressure of oxygen is lower) with increasing altitude - and this is simply because there is less gas overall. Source The reason it ...
How is ‘altitude’ different to sea level? Air is comprised of different molecules, with nitrogen (79.04%) and oxygen (20.93%) making up the majority of each breath we take.
Who is most at risk? Altitude sickness occurs because the higher you climb, the thinner the atmosphere gets. This makes breathing in the same amount of air much harder, so you get less oxygen than you would at lower altitudes. If your body is unable to take the time and adjust to the difference in oxygen, altitude sickness occurs.
