High Altitude Sickness
Understanding the Causes, Symptoms, and Prevention
What is High-Altitude Sickness?
High-altitude sickness is mainly caused by a rapid decrease in the availability of oxygen due to lower air pressure at high altitudes.
When you ascend to a high altitude too quickly, your body doesn't have enough time to adjust to the reduced oxygen levels. The lungs take in less oxygen with each breath, leading to physiological responses like increased breathing and heart rate. This can result in:
- Headache & Dizziness
- Shortness of Breath
- Nausea & Fatigue
General Altitude in Tibet above Sea Level (M)
As illustrated in the graph, the average altitude in Tibet is approximately 4000m above sea level, posing a significant challenge for those traveling directly to areas like EBC. Consequently, we provide a 2-3 day tour in the lower altitude area of Lhasa to enable clients to acclimate before venturing higher.
Useful Tips to Prevent Altitude Sickness
Follow these practical preventive measures for a safe journey.
Acclimatize Slowly
We schedule a 2-3 day exploration of Lhasa city first. This initial experience helps you acclimatize before gradually introducing higher altitude attractions for a smoother adjustment.
Stay Hydrated
Drinking adequate water is crucial. Dehydration can mimic altitude sickness symptoms. Although a direct relation is hard to confirm, staying hydrated is highly recommended.
Eat Well
Maintain a good diet to stay energetic. Focus on consuming high-carbohydrate foods, which play a significant role in replenishing and sustaining your energy levels.
Avoid Vices
Avoid cigarettes and alcohol. Alcohol increases dehydration risk, while cigarettes interfere with your body’s ability to intake oxygen and acclimatize properly.
Take Medication
Medications like acetazolamide (Diamox) can assist in acclimation. Note: Always consult a medical professional before use, as side effects vary by individual.
