The third secluded area we examine is very high elevation meteorology. This will be at elevations above 2 miles in elevation (10,560 feet). At this elevation and higher, the air pressure is relatively low. It will take time for the body to adapt to these low pressures and adverse health consequences can occur above this elevation such as shortness of breath, rapid heartbeat, extreme exhaustion and extreme dehydration. Many people visit these elevations for brief time periods (hours to days) before returning to a higher pressure location. The weather at these higher elevations tends to be windier, colder, and changeable. The high elevation is exposed to the free atmosphere and this helps produce windier conditions. The temperature generally decreases with height thus preparations need to be made for cold weather with low wind chills. The weather can change very quickly also going from mild and sunny to snowy and frigid. Many people have made living around 2 miles in elevation home. Some have made living between 2 and 3 miles in elevation home with proper adaptations. Living above 3 miles in elevation, permanently, generally requires a genetic disposition to being able to handle the extreme low pressure. Genetic adaptations generation to generation include larger hearts and a quicker and efficient flow of blood so that adequate oxygen is delivered throughout the body.
