As Tibet is a remote area at a high altitude, altitude sickness (or acute mountain sickness, AMS) easily occurs. A thorough physical examination is advisable before travelling to Tibet. People with serious heart diseases should not visit Tibet. Those with less serious heart problems need to consult a doctor before starting your trip. People with high or low blood pressure need to consult a doctor before traveling. Try to keep healthy and not to catch a cold before entering Tibet. The first day arriving in Tibet, visitors are advised not to take a bath, smoke and drink alcohol.
Altitude sickness is considered as the biggest health risk for travelling to Tibet. An altitude over 3,000 meters (9,843 feet) is usually defined as high altitude. Tibet is a land with average elevation above 4,000m. Most part area where people can travel and trek is more than 3,000m, so you need to know how to avoid altitude sickness.
Acute mountain sickness is common at high altitudes due to the decreasing availability of oxygen. Most people will appear different degrees of symptoms at high elevation, like headache, nausea, dizziness, fatigue, shortness of breath, loss of appetite and disturbed sleep. The occurrence of altitude sickness depends on the altitude. The higher altitude, the serious symptoms appear. If a tourist suffers from altitude sickness, the best remedy is to take him to a lower altitude. It is extremely dangerous to let him traveling to a higher place that may cause more serious symptoms even death within few minutes.
Though altitude sickness can be very serious, there is only a small part of tourists really suffering from that. Symptoms of altitude sickness include headache, nausea, dizziness, fatigue, shortness of breath, loss of appetite and disturbed sleep. Most people will experience one or more altitude sickness symptoms upon their arrival in Tibet. And they can soon acclimatize on the first one or two days in Lhasa. The symptoms will usually gradually decrease or disappeared.
