Altitudes reter to the altitude at which the person sleeps; ascent is assumed to start trom elevations < 1 200 m; risk categories pertain to unacclimatised
Acute mountain sickness (AMS) is defined as the presence of a headache in an unacclimatised
individual who has recently arrived at high altitude, along with gastrointestinal symptoms, insomnia, dizziness and lassitude or fatigue.
Hypoxia also occurs in unacclimatised
people at high altitude.
If an unacclimatised
person treks higher than 2,500 metres, the rule of thumb is to sleep no more than 300 metres higher than the previous night's camp, and to rest every third day.
High calf mortality can also be the result of poor adaptation of exotic stock, for example when unacclimatised
temperate or crossbred dairy stock are imported to the tropics, thus adding severe climatic stress to the other hazards of calf life.
Heat edema is the mildest form of exercise related heat illness, and most commonly affects unacclimatised
individuals in extreme heat.
That's important if you fly into the gateway city of Leh unacclimatised
Two weeks ago, field hospitals were admitting as many as 10 temperature-related casualties a day after fresh troops from 19 Mechanised Brigade arrived in the region unacclimatised
person would soon lapse into a coma if he or she were lifted from Kathmandu (1,500m) and dropped on Everest's summit (8,848m).
