Do Sherpas Have Bigger Lungs?

Sherpas’ Physical Advantages at Altitude

• Sherpas produce 30% more power than lowlanders at altitude.
• They have more muscle capillaries and bigger chests, greater lung capacity, as well as higher lung physiology measures.

Efficiency in Oxygen Utilization

• Recent DNA studies have found genetic differences between Sherpas and lowlanders.
• Nepalese Sherpas use oxygen more efficiently than those at sea level.

Dietary Staples and Adaptations

• Potatoes provide the Sherpas with their dietary staple.
• Sherpas have lower resting heart and breathing rates than lower altitude populations.
• Larger lungs allow for greater oxygen intake with each breath.

Insights into Resilience

• The Sherpas’ ability to thrive in punishing conditions is a testament to human adaptability.
• Their bodies have been fine-tuned by generations of high-altitude living, underpinning their performance.
