Altitude sickness occurs when you cannot get enough oxygen from the air at high altitudes. This causes symptoms such as a headache, loss of appetite, and trouble sleeping. It happens most often when people who are not used to high altitudes go quickly from lower altitudes to 8000 ft (2500 m) or higher.

Altitude sickness can occur when traveling to an altitude above 6,000 feet (1,829 meters) and traveling faster than the body can adapt.
Can you get altitude sickness at 5000 feet?
When changes in altitude overpower our ability to acclimatize, we can end up with high altitude illness. This can occur at elevations as low as 4-5,000 feet (the city of Denver, Colorado). More commonly, it develops at an altitude of approximately 8,000 feet or above.At what elevation is it hard to breathe?

At what elevation does the air get thinner?
When you travel to a place above about 8,000 feet, your body starts telling you there’s something seriously wrong with the air up there. The “thin” air at high altitudes has considerably less oxygen and pressure.
Is high altitude bad for COPD?
If you have COPD and enjoy traveling, then you might already know that high altitude can make COPD symptoms worse. At higher elevations, your body needs to work harder to take in the same amount of oxygen as it does at elevations closer to sea level. This strains your lungs and makes it harder to breathe.

How long does it take to acclimate to 6000 feet?
The major cause of altitude illnesses is going too high too fast. Given time, your body can adapt to the decrease in oxygen molecules at a specific altitude. This process is known as acclimatization and generally takes 1-3 days at that altitude.
At what elevation do you need oxygen?
Most people will agree that supplemental oxygen should be used at the ‘Death Zone’ of 26,000 feet (8,000 meters). However, altitude sickness can set it at a much lower altitude, and depending on each individual, you should start using oxygen when you experience moderate altitude sickness.
