What is Acute Mountain Sickness (AMS) And How to Avoid It?
The high altitude is one of the difficulties to travel to Tibet. But it is not so serious as you imagined if you know it and get good preparation for it.
What is High Altitude?
- High Altitude: 1500 - 3500 m (5000 - 11500 ft)
- Very High Altitude: 3500 - 5500 m (11500 - 18000 ft)
- Extreme Altitude: above 5500 mhas.
