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.
