Hats off to all the Sherpas! They are a true mountaineers.

But we must understand that Sherpas have superhuman power. Like for real! None of us without their genes can push the body at high altitudes so effortlessly. 

Sherpas possess remarkable genetic adaptations enabling them to thrive at high altitudes. One key adaptation is their body's ability to produce more nitric oxide, which facilitates better blood flow and enhanced oxygen delivery to vital tissues. Additionally, they exhibit higher hemoglobin concentrations, aiding in superior oxygen transport throughout the body. A notable feature of their cellular structure is a higher concentration of mitochondria, the energy-producing powerhouses, that continue to operate efficiently even under reduced oxygen conditions. Unlike many lowlanders who respond to lower oxygen levels by ramping up red blood cell production, Sherpas maintain a relatively normal red blood cell count. This unique physiological response is an evolutionary advantage, as it allows for efficient oxygen utilization without the need for increased red blood cell production.
