Health and safety is a significant matter for the travelers, no matter where are you traveling. Immunization and Acute Mountain Sickness are the most health problem that occurs in Tibet while traveling. Before arrival, you should be aware of some immunize problems as hepatitis A, hepatitis B, typhoid, and diphtheria/tetanus. Acute Mountain Sickness is another problem that may arise when you visit Tibet. It is in more than 4000 meters for which you may need acclimatization. It is better to bring sufficient liquids like water and juices. If you are traveling somewhere out of Lhasa, then be prepared to avoid sunstroke, sunburn, dehydration, and frostbite. Be informed about the climate and travel with guides.
