Unravelling the Mysteries: Swimming in Mount Everest’s Glacial Lakes

Nestled among the jagged, icy peaks of the Himalayas, Mount Everest stands as a symbol of challenge and endurance. Renowned globally for its extreme weather conditions and towering heights, this mountain range is popularly associated with trekking, climbing, and record-setting adventures. However, one possibility that’s seldom talked about is swimming in one of Mount Everest’s glacial lakes. Let’s explore if anyone has ever dared to dive into these icy depths.

The Glacial Lakes of Mount Everest

These high-altitude, glacial-fed lakes on the slopes of Mount Everest are stalwarts against the persistent, biting cold. Created by melting glacial ice, they possess a mystical, ethereal beauty that captivates everyone. However, their sparkling, clear waters hold incredibly low temperatures, making them potentially lethal to unprotected swimmers. One such example is the Imja Tsho, a glacial lake that sits over 5,000 meters above sea level.

The Daring Few: Swimming on the Roof of the World

To date, there is only one recorded person known to have braved these icy waters – Lewis Pugh. In 2010, this brave adventurer, known as “the human polar bear”, swam a full kilometer across Pumori Lake, one of the glacial lakes near Mount Everest, in a jaw-dropping time of 22 minutes and 51 seconds, setting a new world record. The freezing waters, with a temperature of just 2 degrees Celsius, would have proved fatal to most others. For Pugh, this swim was more than just a personal challenge. It was an attempt to raise global awareness about the melting glaciers and the resultant risks posed by climate change.

The Risk and the Reality

Despite the thrill and adrenaline rush it might evoke, using these icy-cold glacial lakes as swimming pools is a risk-ridden affair. These lakes boast sub-zero temperatures that can lead to hypothermia and cause death within minutes for unprepared individuals. 2 degrees Celsius might not sound intimidating, but in water, this can procure a swift and lethal response from the body. The high altitude, extreme cold, and potential for sudden weather changes all contribute to making this endeavor a dangerous one.

The Inherent Challenges

Swimming in these glacial lakes also poses the challenge of hypoxia, the lack of sufficient oxygen, due to their high altitude. The physical stresses stemming from both the cold and lack of oxygen make this a feat that only the most trained and acclimated individuals should attempt. It should be noted that even Lewis Pugh undertook extensive acclimatization and had rescue teams on standby to ensure his safety.

Preserving the Natural Beauty

While the thrill of swimming in these glacial lakes might be enticing to some, it is important to remember the fragile ecology of these locations. Ensuring the preservation of these unique ecosystems must take precedence over personal adventures. The impact of swimming in these lakes, particularly with oils, sunscreen and other aesthetic products on the skin, could potentially harm their delicate balance.


1. Who is the only person to have swum in Mount Everest’s Glacial Lakes?

Lewis Pugh is the only person recorded to have swam in Pumori Lake, a glacial lake near Mount Everest.

2. What was the temperature of the water when Lewis Pugh swam?

The water temperature was recorded at a chilling 2 degrees Celsius when Lewis took his record-setting swim.

3. Why is swimming in these glacial lakes dangerous?

Swimming in these lakes can be deadly due to their sub-zero water temperatures, leading to rapid hypothermia. Combined with the high altitude, lack of oxygen (hypoxia), and unpredictable weather, it is a high-risk activity.

4. Can swimming in Mount Everest’s glacial lakes harm the ecosystem?

Yes, human activity such as swimming, especially with oils, sunscreen, or other beauty products on the skin, can disrupt the delicate balance of these ecosystems and potentially cause damage.

5. Why did Lewis Pugh swim in a glacial Lake near Mount Everest?

Lewis Pugh undertook this daring feat to raise global awareness of climate change and its impact on glacial meltdown.
