Everest’s Death Zone: How It Ravages the Human Body
The great Mount Everest stands as both a symbol of triumph and a reminder of defeat. It is a place where fearless explorers chase glory, fully aware that they may lose everything in the process. It is more than a test of physical endurance; it is a relentless struggle against some of the harshest conditions on Earth.
As the highest point on the planet, Everest represents the ultimate challenge, drawing climbers from every corner of the globe. Here, the human body begins to fail rapidly; there are only a few precious hours in which to survive, and even the simple act of breathing becomes a desperate fight. On this unforgiving peak, even the most seasoned climbers find themselves at the mercy of nature’s most brutal extremes.
Inside Everest’s Death Zone: The Science
The Death Zone of Everest begins at 8,000 meters (26,247 feet), where air pressure is so low that oxygen content is just one-third of what we breathe at sea level. At this altitude, the body begins to collapse. Breathing becomes difficult even at rest, and without supplemental oxygen, most would not survive more than a day.
Climbers in the Death Zone are rapidly deprived of oxygen. This brings on confusion, dizziness, poor judgment, and other dangerous symptoms while navigating steep, icy slopes. Hallucinations and memory loss are common symptoms due to reduced oxygen flow to the brain. The fatigue you may experience is extreme; every step can become a monumental task. The risk of death from altitude sickness, such as HAPE (fluid in the lungs) or HACE (brain swelling), increases sharply, even for highly experienced, physically fit climbers.
Adding to the danger are Death Zone temperatures, which can drop to -30°C (-22°F) or lower with wind chill. Frostbite can occur within minutes, and snow is difficult to melt, leading to dehydration. Even bottled oxygen only delays the body’s breakdown. The Death Zone is not a place to linger, it must be crossed swiftly. Prolonged exposure is deadly, so climbers plan summit attempts carefully to minimize time spent in this lethal zone.
Death Zone Survival: Oxygen & Temp Limits
Surviving the Everest Death Zone is a race against time. Without oxygen from a tank, the human body can survive only 16 to 20 hours before vital systems begin to collapse. Most climbers use supplemental oxygen, but it only postpones the failure of the body. Breathing is still difficult, and even slight movements feel like they would drain your strength. The Death Zone temperature on Mount Everest is -20°C to -30°C. It is even colder with wind chill. Frostbite in minutes and dehydration due to dry air and hyperventilation are common. In Everest’s Death Zone, the top three threats every climber faces are running out of time, running low on oxygen, and battling extreme cold. The only option to survive is to climb fast, rest as little as possible, and descend rapidly after the summit is reached.
What Happens to The Body in the Death Zone?
Entering the Mount Everest Death Zone is like approaching a slow-motion medical emergency. At such an advanced altitude above 8,000 meters, the human body is pushed to its extremity. Oxygen is in scant supply, and the temperature is appallingly cold. The longer the climber remains within the Death Zone, the more severe and permanent the damage becomes.
- Cognitive Dysfunction: Oxygen-starved brains slow down. Climbers may forget safety steps, misjudge distances, or fail to react to danger.
- Chest Tightness & Coughing: High Altitude Pulmonary Edema (HAPE) can cause lungs to fill with fluid, making each breath painful and shallow.
- Swelling & Headaches: High Altitude Cerebral Edema (HACE) causes the brain to swell, leading to headaches, nausea, and loss of balance.
- Frostbite Risk: Blood flow slows in the cold, making fingers, toes, and facial features vulnerable to freezing within minutes.
- Impaired Judgment: Many climbers “feel fine” even as their bodies shut down. Poor decisions made in this state can be fatal.
The Haunting Reality: Dead Bodies on Mount Everest
Mountaineers perish each year in the Mt Everest Death Zone, and others are stranded on the mountain permanently, frozen by the freezing cold and the extreme altitude. Such mountaineers, the casualties of the Everest Death Zone, are mournfully abandoned with their expeditions culminating in a tragic result. Whereas others are saved or descend after their summit bid, most remain on the mountain as a warning of the hazardous ascent. Since time immemorial, a series of corpses have become legendary landmarks for would-be climbers of the fatal climb. They stick in place, a grim reminder of the perils of ascending Everest.
Sleeping Beauty Everest
One of the most famous and poignant leftovers is that of “Sleeping Beauty,” an American climber whose frozen body was discovered in a sleeping position on the north side of the mountain in 1998. Wrapped in a red mountaineering suit, she appears to be sleeping peacefully, though the freezing air and lack of oxygen took her life. Her body came to be a grisly milestone on the route to the top. The “Sleeping Beauty” nickname implies both the macabre serenity of her pose and the tragedy of her untimely demise. Her identity remains unknown despite her fame among mountaineers, and very little is known about her life and climbs.
Green Boots Everest
It’s arguably the most recognizable corpse on Mount Everest, that is, “Green Boots”. The name is bestowed upon an unknown mountaineer who died on the northeast ridge in 1996 in a howling tempest. His lime green climbing boots, highly visible along the path, are now an evocative marker for climbers attempting to reach the summit. Green Boots’ body was discovered lying beside a rock outcrop, his body in the position he had fallen from, trying to seek cover from the storm. His body remained uncovered for decades, serving as a marker for climbers passing through. Over the years, his identification has been the topic of much debate, with people believing that he is Tsewang Saman, a member of an Indian expedition. Despite efforts to pull his body out, Green Boots is a permanent inhabitant of the Mount Everest Death Zone, a sombre landmark marking the perils of the climb.
Rainbow Valley Everest
Rainbow Valley Everest is employed to describe a region near the summit of Mount Everest, not selected for appearance but for its colourful, gaudy, down-padded parkas abandoned by the climbers who were killed when they were discovered strewn across the snow. These climbers, who were killed when heading down to the base camps after reaching the summit, are a product of what occurs in the Death Zone. The highly visible coloured jackets stand out sharply in contrast to the white snow, tinging the valley with their ghostly, otherworldly appearance.
Recovery of bodies is difficult at Rainbow Valley, and even some climbers float on by without possessing the ability to help, altitude and cold weather exclude them effectively enough to engage in rescue activities on the ground. Rainbow Valley is one of the most heartbreaking spots on Everest, a somber reminder of what can happen to those who do not return from the summit.
Why Hundreds of Bodies Remain on Everest?
Bringing bodies down from the Death Zone on Mount Everest is almost impossible because of how dangerous it is. The air is very thin, the weather is unpredictable, and the ground is steep and icy. These tough conditions make recovery missions extremely risky. Helicopters can’t fly well above 6,000 meters, and even if they could, the narrow ridges, tall ice walls, and sudden storms make flying and rescue almost impossible. There’s also very little equipment or support that high up, which makes things even harder.
When climbers die in the Death Zone, their bodies are usually left behind because trying to bring them down is too risky. Even skilled climbing teams have a hard time staying safe, so adding a recovery mission can be too dangerous. Rescuers can suffer from extreme tiredness, frostbite, or even die while trying to help. Most of the bodies stay where they are, frozen in place by the cold. These bodies are a sad reminder of how dangerous Everest really is. The truth is, not everyone who climbs the mountain makes it back.
The Ethical Dilemma: Recovering Everest’s Dead
There has been a long debate about whether or not to rescue or bring back the bodies of climbers who died on Mount Everest. Many climbers believe in the idea of “resting where you fall.” This means they accept the risks of climbing Everest, including death, and think their body should stay where they died. Mount Everest is one of the most dangerous places in the world, and climbers know this before they go. Some people believe it is disrespectful to move someone’s body after they’ve died on the mountain.
On the other hand, some people believe that bodies should be brought back, especially for the sake of the climber’s family and friends. Bringing a body home can help give people closure and peace. But getting a body off the mountain is very hard. In a part of Everest called the “Death Zone,” where the air is thin and the weather is very cold, every move can be risky. Trying to move a body can take many hours or even days. The people who try to do this must face extreme tiredness, the chance of frostbite, and the danger of dying from the high altitude.
Even if a body is recovered, it may not be possible to return it to the climber’s home country. The body must be protected from freezing temperatures, and the effort to do that can be very stressful. Some people wonder if it’s worth risking more lives to try and bring back someone who has already died.
