Why are There So Many Deaths on Mount Everest?

The allure of Mount Everest, the highest peak in the world, is unarguably irresistible. The majestic and often perilous mountain resides in the Himalayas of Nepal, at an astounding height of 29,032 ft. It has attracted mountaineers from around the globe for decades, each with a dream to conquer its summit. Mount Everest has become a symbol of grandeur and power, inviting adventure seekers to prove their mettle against its unprecedented height. However, achieving this dream is not without risk.

The Dangerous Appeal of Mount Everest

Mount Everest is, by no means, a trek for the faint-hearted. Despite equipped with cutting-edge gear and guided by seasoned sherpas, climbers still face perilous and often fatal challenges. It is these constant challenges that make it the perfect ground for understanding why it holds a high mortality rate.

Extreme Weather Conditions

Fundamentally, the harsh weather conditions and extreme cold on the Everest are one of the main causes of fatalities there. Powerful winds and deadly blizzards can suddenly appear out of a clear sky. The temperature can drop to -60 degrees Celsius, leading to potentially fatal hypothermia. Frostbite is also a common hazard due to the extreme cold, which can result in amputation and in severe cases can lead to death.

The ‘Death Zone’ Impact

Nicknamed the Death Zone, the region above 8,000m (26,247 ft) on Mount Everest is perhaps the deadliest of challenges awaiting climbers. The Death Zone is marked by an incredible scarcity of oxygen and meagre atmospheric pressure. The lack of ample oxygen can lead to altitude sickness, causing dizziness, nausea, shortness of breath, and in severe cases, even fatality.

Exhaustion & Overexertion

Exhaustion is another serious enemy of those who attempt to scale Everest. The physical exertion and the psychological stress both drain a climber’s strength. Traversing turbulent weather, bracing wind chills while hauling heavy equipment up challenging inclines can often lead to energy depletion.

Mountaineering Accidents

Mount Everest climbing is fraught with risks. Avalanches, crevasses, rockfall, and flimsy ice cliffs (Seracs) can cause accidents at any step. Several climbers have met their end due to these unavoidable natural hazards.

The Impact of Overcrowding

Finally, overcrowding has emerged as a prominent risk factor in recent years. With the surge of mountaineering tourism, traffic jams on the climbing route are becoming common. This slows down the ascent and descent, prolonging climbers’ exposure to high altitude and harsh weather. Consequently, this can increase the likelihood of fatigue, frostbite, and altitude sickness.


Mount Everest is a test of ambition and human endurance. Despite the dangers, climbers continue to flock to its challenging peaks. However, with every successful summit comes a myriad of failed attempts, many resulting in fatalities. It is an odyssey that should never be underestimated, requiring immense physical prowess and psychological resilience.
