If you are a hiker, you might have heard that Mount Everest is the tallest mountain in the world, towering at a height of 29,029 feet. Climbing the mountain is no easy feat, as the altitude poses several challenges to the human body.
One of the challenges is the inability to boil water on Mount Everest. And in this beginner’s guide, we will explore the reasons behind this phenomenon.
The Basics of Boiling Water
Boiling is the process of transforming water from a liquid state to a gaseous state by raising its temperature to its boiling point, which is 100°C (212°F) at sea level. When water boils, its molecules gain energy and move rapidly, causing the water to turn into steam. The steam that rises from the boiling water is at the same temperature as the boiling water itself.
Altitude and Air Pressure
The boiling point of water is affected by altitude and air pressure. As you increase in altitude, the air pressure decreases, and the boiling point of water lowers. In fact, for every 500-foot increase in altitude, the boiling point of water decreases by about 1°F. At high altitudes, the reduced air pressure causes water to boil at a lower temperature.
The Effects of High Altitude on the Human Body
When you are at high altitudes, your body experiences several changes due to reduced air pressure and oxygen levels. At altitudes above 8,000 feet, the air pressure decreases, and the body receives less oxygen.
This lack of oxygen can cause altitude sickness, which includes symptoms such as headaches, nausea, dizziness, and fatigue. Acclimatization, which is the process of adjusting to high altitudes, can help reduce the severity of altitude sickness.
The combination of Altitude and Boiling Water
Now that we understand the effects of altitude on the human body and the boiling point of water, we can start to see how these two factors combine to make it impossible to boil water on Mount Everest. At the summit of Mount Everest, the air pressure is only one-third of what it is at sea level.
This means that the boiling point of water is much lower than 100°C. In fact, at the summit, water boils at around 68°C (154°F). This temperature is not hot enough to properly cook food or to make a hot cup of tea.
Alternative Ways to Cook Food and Purify Water
So, if you can’t boil water on Mount Everest, how can you cook food and purify water? One method is to use a pressurized stove, which raises the air pressure and allows water to boil at a higher temperature.
Another option is to use chemical water treatments or filtration systems to purify water. These methods are popular among hikers and mountaineers who need to purify water for drinking and cooking.
The Dangers of Dehydration
When you are climbing Mount Everest, dehydration is a real concern. You need to stay hydrated to avoid altitude sickness and other health problems. However, with the inability to boil water, it can be difficult to find safe drinking water.
The body loses water through sweating, breathing, and urination, and if you don’t replace the lost fluids, dehydration can occur. Symptoms of dehydration include thirst, dry mouth, fatigue, and decreased urine output. Severe dehydration can lead to heat exhaustion, heatstroke, and even death.
Preparing for High Altitude Environments
If you are planning to climb a high-altitude mountain, it’s essential to prepare yourself properly. This includes physical training, acclimatization to high-altitude environments, and researching the specific challenges of the mountain you plan to climb.
Physical training can help you build the strength and endurance needed for the climb, while acclimatization can help your body adjust to the high altitude and reduce the risk of altitude sickness. Researching the mountain you plan to climb can help you understand its specific challenges and prepare accordingly.

Frequently Asked Questions (FAQs)
Q: Why is it dangerous to drink untreated water on Mount Everest?
Drinking untreated water on Mount Everest can lead to illness and dehydration. The water may contain bacteria, viruses, and parasites that can cause gastrointestinal problems. Additionally, the altitude can cause dehydration, which can be exacerbated by drinking contaminated water.
Q: How do pressurized stoves work?
Pressurized stoves work by increasing the air pressure inside the stove, which raises the boiling point of water. This allows the water to boil at a higher temperature, making it possible to cook food and purify water at high altitudes.
Q: How long does it take to acclimate to high altitudes?
The time it takes to acclimate to high altitudes varies depending on the individual and the altitude. Generally, it takes several days to a few weeks to acclimate to altitudes above 8,000 feet. During this time, it’s important to stay hydrated, avoid alcohol and smoking, and take it easy to allow your body to adjust.
Q: Can you climb Mount Everest without experience?
Climbing Mount Everest requires a high level of physical fitness and experience. It’s important to have experience climbing other high-altitude mountains before attempting to climb Mount Everest. Additionally, climbers must undergo rigorous training and preparation to ensure they are physically and mentally prepared for the climb.
Q: How do you stay hydrated on Mount Everest?
Staying hydrated on Mount Everest requires drinking enough fluids to replace the fluids lost through sweating, breathing, and urination. It’s important to drink water regularly, even if you don’t feel thirsty, to prevent dehydration. Additionally, you can eat foods with high water content, such as fruits and vegetables, to help maintain hydration.
In conclusion, boiling water on Mount Everest is impossible due to the combination of altitude and air pressure. At the summit of the mountain, the air pressure is only one-third of what it is at sea level, causing water to boil at a much lower temperature than 100°C.
Alternative methods such as pressurized stoves and chemical water treatments can be used to cook food and purify water. It’s important to prepare properly for high-altitude environments to reduce the risk of altitude sickness and dehydration.
