It is very easy to get sunburnt in Tibet. Sunburn can be more than just uncomfortable. Among the undesirable effects are premature skin ageing and possible skin cancer in later years. Sunscreen ( UV lotion) with a high sun protection factor( SPF>30) , good quality sunglasses and a wide-brimmed hat are good means of protection.

Those with fair complextions should bring reflective sunscreen( containing zinc oxide or titanium oxide) with them. Apply the sunscreen to your nose and lips and note how many hours it works.
