First of all, due to Tibet’s high altitude and different climatic conditions to the Mainland, experts advise that tourists entering Tibet should take preventative measures towards altitude sickness including headaches, dizziness, palpitations and shortness of breath. All those suffering from chronic respiratory diseases or cardiovascular disease should take particular care.
Secondly, autumn sunshine in Tibet is still strong so tourists should take sunglasses, sunscreen, lip balm and others. Due to large temperature differences between day and night, tourists should take plenty of clothes, preferably jackets. A fleece can be worn when hot during the day and an additional jacket when out in the morning or evening.
Thirdly, during the first three days in Tibet, tourists should take plenty of rest and not too much exercise and tourist activities. Tourists should drink plenty of water and avoid eating spicy food, try to eat easily digestible foods, such as vegetables and fruit, and avoid smoking and drinking alcohol.
Finally, tourists should gather an understanding of the local customs and taboos beforehand. Tourists should must watch their own words and actions, pay attention to ethnic unity, respect the Buddha and keep hands off. Tourists should respect Tibetan customs, for example when a Tibetan offers butter tea, do remember to take it with both hands and definitely not one. The customs of the Tibetan inhabited area are deeply influenced by religion; some habits can’t be compared to the standards of urban people, so don’t make a fuss or criticize them. Take care when taking pictures of people, especially women, as Tibetans don’t necessarily like having their picture taken. In order to avoid unnecessary trouble, say hello before taking a picture.
