The Genetics of High-Altitude Living Science AAAS

WebLow humidity, dry air and increased respiratory rate are all factors that contribute to dehydration at high altitude. Above 6,000 feet, the body exhales and perspires twice as much moisture than at sea level. Also as a result of lower air pressure moisture from the skin is evaporated at faster rates that can cause dehydration. WebAir pressure decreases exponentially as altitude increases, as shown in the graph below (Figure 6.6.2). Figure 6.6.2 As altitude increases, atmospheric pressure decreases, which means there are fewer molecules of oxygen in a single breath at high elevations than a single breath at lower elevations. At sea level, air pressure is about 100 kPa. importance of behaviour change
