Altitude sickness means the illness occurring at higher altitude. In this time your breathing and heart rates increases. Altitude sickness normally happens above 2800m and symptoms consist of headache, dizziness, dehydration and trouble sleeping. To help avoid this illness we recommend you to drink at least 3 liters of water per day, trek slowly and use acclimatization days. Altitude sickness happens in varying degrees, and it depends form person to person. As Tibet is such a high place and it can be difficulty to descend quickly if you have altitude problems, you take every precaution to prevent them. Acclimatization is the best way, a road trip over 4 or 5 days to Lhasa is the best way to acclimatize. You should drink plenty of water also as this can help.
