About Acute Mountain Sickness (AMS), it normally a slight reaction will take place for sure especially for the travelers who come to Tibet for the first time. AMS represents the body's intolerance of the hypoxic (low oxygen) environment at one's current elevation. the typical symptoms would appear on the facets like headache, dizzy, feels of to be disgusted, vomit and etc. but if only do you follow the necessary instructions from our tour guide and everything should be okay. And the major cause of AMS is going too high too fast. Given time, your body can adapt to the decrease in Oxygen molecules at a specific altitude. This process is known as acclimatization and generally takes 1-3 days at that altitude. And when acclimatization lags significantly behind ascent, various symptoms occur. To prevent of the Altitude Illness, the most important thing is you can't over-exert yourself or move higher for the first 24 hours and you'd better not to take any activities for the first day in Tibet. Normally you will regain normal sense on the second day upon your arrival.

Tips to Avoid and Treat AMS:

2) Avoid catching a cold before you entry to Tibet.

3) Make sure you have a good sleep the night before you flying to Lhasa;

Although it originally was released as a diuretic (water pill), it also helps you breath deeper and faster. This allows you to get more oxygen. Diamox is especially helpful with the sleeping problems and other symptoms of A.M.S. Avoid sleeping pills because they may cause shallow breathing at night and make it more difficult for your body to absorb oxygen while you sleep.
