How to stay safe when exercising at altitude— published: 02-05-2013
Performing physical activity at moderate (4,000-7,870 ft or 1,200 to 4,000 m) and high (7,870-13,125 ft or 2,400 to 4,000 m) altitude can be challenging. At high altitude, oxygen pressure is lower which results in less oxygen in the blood and muscle tissues. As altitude increases, there is a decrease in air temperature (about 20 F for every 500 ft or 152.4 m), less moisture so the air is drier, and increased solar radiation. Use sunscreen, drink plenty of water, and watch out for the signs of acute mountain sickness: headache, nausea, shortness of breath, impaired cognition and balance.
