The 'Death Zone' of Mount Everest - what it really is, and why it’s so deadly

The Death Zone, above 8,000 meters on Mount Everest, is a literal physiological boundary where the human body cannot survive long due to critically low oxygen levels. Even with acclimatization and supplemental oxygen, the body deteriorates rapidly, leading to impaired judgment, extreme fatigue, and life-threatening conditions like HACE and HAPE, making rescue nearly impossible.
