Prepare your first aid kit before getting to Tibet. In addition to the normal bandages, salves, etc. one should fortify the kit with medicine for diarrhea, giardiasis, hepatitis and other diseases tourists may encounter on the plateau. Medicine for respiratory tract infections, such as colds, influenza and bronchitis which may further diminish oxygen intake also shall be included to prevent those diseases since they may result in serious consequences on the Tibet plateau. Vaccinations can be taken to assure a healthy and enjoyable tour. Medicine can be obtained from pharmacies, most of them on Yuthok Lu in Lhasa.

You will be exposed to climate extremes as well as altitude extremes in Tibet. The temperature differences in day and night is huge, so take precaution not to catch cold, which, because of Mountain Sickness, could possibly be fatal in Tibet. The strong sunshine may injure your skin and eyes, so bring your sunscreen and sunglasses. The sun is much stronger at this elevation because there is little atmosphere to filter its rays. Sunburn can occur easily even though you do not feel it at first. Also, use creams to keep the skin of the face and hands moisturized as the air at this elevation is very dry and the wind will dry your skin rapidly.

Since boiling temperature is somewhat lower in Tibet, it is better to boil water for longer period of time. Drinking water should be purified with iodine or other purification tablets before drinking to prevent intestinal complaints.

Packs of wild dogs roaming around monasteries and villages are a feature of Tibet and also a potential threat. Get a rabies vaccination (human diploid cell vaccine or purified chick embryo culture vaccine) in advance and stay away from them. For details of the vaccination, consult your doctor.

Visitors to remote areas may see wild animals, such as wild yaks, Tibetan antelopes and such. Keep your distance from them for safety.
