A period of adjustment will be necessary with drastic altitude and/or weather changes. Symptoms of high altitude sickness, which usually occur at elevations greater than 8,000 feet, are headache, nausea, weakness and shortness of breath. If severe shortness of breath or confusion develops, delivery of oxygen and transfer to a lower altitude are necessary. The best prevention is a slow ascent: approximately 300 meters per day is good. Use moderation in exercise, alcohol consumption and tobacco use for the first few days to become accustomed to your new environment.
