Acute Mountain Sickness (AMS) is common at high altitudes and
depends on the elevation, the rate of ascent and individual
susceptibility. Most visitors to Tibet will suffer from at least
some symptoms which will generally disappear through
acclimatization after several hours or a few days.?
Symptoms tend to be worse at night and include headaches,
dizziness, lethargy, loss of appetite, nausea, breathlessness and
irritability. Difficulty in sleeping is also a common symptom and
many travelers have trouble with this for the first few days on
arriving in Lhasa.
To prevent acute mountain sickness:
?
l????????
Drink extra fluids. The mountain air is dry and cold and moisture
is lost as you breathe. Evaporation of sweat may occur unnoticed
and result in dehydration.
l????????
Eat light, high-carbohydrate meals for more energy.
l????????
Avoid alcohol as it may increase the risk of dehydration and don't
smoke.
l????????
Avoid sedatives.
l????????
Don't push yourself when walking or climbing and take plenty of
breaks.
l????????
Try to avoid catching a cold before entering Tibet.
