What are the symptoms of altitude sickness?
Symptoms of altitude sickness can vary from mild to severe and may include:
- Headache
- Nausea or vomiting
- Fatigue
- Dizziness or light-headedness
- Difficulty sleeping
What causes altitude sickness?
Altitude sickness is caused by a lack of oxygen when you are at high elevations. As you go higher, the amount of oxygen in the air decreases, making it harder for your body to get the oxygen it needs. Rapidly ascending to high altitudes can overwhelm your body’s ability to adjust.
How common is altitude sickness?
Altitude sickness can affect anyone who goes to high altitudes, especially those who do not allow time for adjustment. About one in three people who travel above 2,400 metres (8,000 feet) may experience some symptoms.
Who is more likely to get altitude sickness?
Certain people may be more likely to experience altitude sickness, including:
- People who live at sea level and fly to high altitudes quickly
- Those with a history of altitude sickness
- Individuals who have certain medical conditions, such as asthma or heart problems
How can I treat altitude sickness?
If you start to feel symptoms of altitude sickness, there are several steps you can take:
- Descend to a lower altitude as soon as possible
- Stay hydrated by drinking plenty of water

How quickly can I recover from altitude sickness?
Most people who experience mild altitude sickness can recover within a few hours to a few days, especially if they descend to a lower altitude and take care of themselves. However, recovery may take longer for those with more severe symptoms.
What’s the outlook for altitude sickness?
Most people recover fully from altitude sickness with proper care and precautions. However, severe cases can lead to serious health issues and should be treated immediately.
