how to manage high-altitude illnesses
The Public Health Agency of Canada is advising on how to manage high-altitude illnesses.
Acute mountain sickness occurs in up to 25% of adults ascending to 2000 m. Symptoms are usually headache, nausea, vomiting, etc.
The risk increases with altitude and ascent rate. Tell climbers to stop if symptoms occur and allow 0.5 to 4 days to acclimatize.
