Why I have a risk to get the high altitude sickness in Tibet?
High altitude sickness is generally caused by acute exposure to low air pressure. It usually occurs around 3,000 m. (9,843 ft.) above sea level. Most regions in Tibet are at an altitude of over 3,000 m. (9,843 ft.)
Cold temperatures, high fever and extreme fatigue can all lead to altitude sickness. Find more information about the high altitude sickness.
