Winter is also a good time to visit places along the Yalutsangpo valley, such as Lhasa, Tsetang, Nyinchi, Gyangtse & Shigatse, for the day time temperature is about 15ˇć above zero.
One of the important factors the visitors to Tibet concerned about is the mountain sickness, because the average elevation of Tibet is about 4000 meters above sea level. If you have never been to highland before, you may feel a little bit uncomfortable when you first arrive there, such as headache, dizzy, heavy breathing, tired and insomnia, for the air there contains less oxygen. But these uncomfortable feelings will disappeared automatically after one or two days. Those with heart diseases or high blood pressure should be much more careful and better consult a doctor before going to Tibet.
