7. The Sherpas Are Expert Mountain Climbers
Climbing Everest or any other mountain would be a daunting task for the average person. But not for the Sherpas. They are expert mountain climbers with the ability to seek out previously unknown routes. Today, people climbing Mount Everest always go with Sherpa guides.
Research revealed that Sherpas are excellent mountain climbers because their bodies manage oxygen better at higher altitudes than the average person. This should not be a surprise. The Sherpas have been living on the Himalayas for over 6,000 years, which is more than enough time for their bodies to adapt to the extremely cold temperatures and low oxygen levels. The Sherpas are also immune to the nasty side effects and sometimes fatal ailments that affect other climbers.
Oxygen decreases as we go higher up Mount Everest. In response, the body produces more red blood cells to feed the muscles with the required oxygen. At the same time, these excess blood cells make the blood thicker, stressing the heart.
The Sherpas also experience the same thing but at a much lower rate. This is not all. Their bodies are also able to produce more energy in the absence of oxygen.
