Key Takeaways – How Mountain Climbers Poop in Cold, High Altitudes
-
High altitudes (above 2,400 m) reduce oxygen levels, affecting breathing, physical performance, and digestion.
-
Cold mountain conditions increase urination and passing wind due to bodily responses to low pressure and temperature.
-
Contrary to expectation, climbers often defecate less at high altitudes because of metabolic and digestive changes.
-
“Poop tubes” are portable PVC containers used to store and transport waste, keeping mountains clean.
-
The waste collection process involves using paper bags with kitty litter to control odour before sealing them in the tube.
-
Portaledges provide a safe, harness-secured platform for climbers to handle waste during ascents.
-
Mount Everest once faced severe waste pollution from decades of climber faeces left behind.
-
Modern waste management practices help protect fragile mountain environments and support the “Leave No Trace” ethic.
-
Proper waste disposal is critical to preserving climbing routes, preventing contamination, and protecting fellow climbers.
-
First aid training, like CPR First Aid’s Liverpool course, prepares climbers for medical emergencies in extreme conditions.
As the famous children’s book says, everyone poops. Whether young or old, tall or small, male or female, and even animals and organisms, they all need to shed waste when the body no longer uses it.
This process of releasing waste is cyclical and occurs occasionally. So, what would happen if a person were in a dangerous or out-of-the-ordinary place? How would they heed the call of nature in such frigid and high environments?
Let’s find out how to hikers who climb cold mountains poop.
Understanding The Effects of Altitude
Living at a high altitude introduces several changes to a person’s body. Before we get to the topic, let’s first understand altitude and the many changes in our bodies in response.
What is Altitude?
By definition, altitude is the distance between a higher point and ground or sea level. Therefore, going up a small hill or taking an elevator up ten floors puts a person at altitude.
A distinction must be made, though, when referring to high altitude.
With high altitude, a person must reach over 2,400 metres above sea level. Thus, some mountains don’t consider this type of altitude.
At greater heights, air begins to thin. This is because weaker pressure groups these air molecules together. That is why breathing at the top of a high mountain becomes harder.
How Does Altitude Affect the Body?
Besides hampering one’s breathing, altitude introduces many changes to the body.
Physical Performance
For starters, physical performance or ability is lessened. This is mainly because it is harder to breathe up in the mountains.
Less oxygen travels to various organs and muscles since little air is brought into the body. Without enough oxygen, the muscles lack the energy to perform intensely for extended periods.
The extreme temperatures also open up room for hypothermia to set in, leaving climbers weak and unable to function.
Appetite and Dehydration
Another effect of altitude is on one’s metabolism. Height enhances a person’s metabolism, meaning they burn more energy. At the same time, it also lessens a person’s appetite. This means that if they want a lot of energy for the climb, people will have to eat more than they want.
At this height, the rate of water loss similarly increases due to the cold. Thus, if left unchecked, dehydration could occur quickly.
Urinating
If you’ve ever been in a cold room at home for extended periods, you’ll likely know how the frigid temperatures affect your urinating.
The cold circulates more blood within the body. As more blood passes through organs, more blood must be filtered out, which happens with urination.
Passing Wind
Along with urination also comes the increased need to pass wind or fart. This is because of the lower pressure felt when residing in high altitudes.
The explanation is that less pressure on the stomach leads to increased intestinal gas, which means the need to pass it more often.
There is also a theory that the higher altitudes affect a person’s bowels.
Defecating
Finally, we have what we came for, which is defecating. With the increase in urination and passing wind, one would assume that people at altitude also need to poop more. However, the answer is surprisingly the opposite.
When high above sea level, people tend to defecate less than average. Explanations for this are sparse, with some hinting at either the belly carrying more gas or more energy being burned as the culprit.
Despite that, hikers still need to go, even in cold mountains. The question now is, how do they do it?
How Mountain Climbers Poop?
Everything about climbing a tall mountain is pretty extreme. From the sheer height, the physical prowess needed, and the courage to face the odds, climbers can do it all. So why not defecate in altitudes as well?
Often, the simplest solution is the best one. One would think that people merely crouch over an edge and let their waste fall. However, this is a terrible solution as it will cover the mountain entirely in faeces. In addition, it could hit other climbers square on the face when climbing. Yuck!
Fortunately, climbers have experienced this and come up with more elegant solutions. This one comes in the form of a tube.
The Poop Tube
This tube was designed for climbers to expel their waste and not leave it in the mountains. It comprises a 10-inch-long, 4-inch-diameter PVC pipe with caps on both ends.
Now, climbers won’t be doing their business inside these tubes, which help them keep the mountains clean by allowing them to haul their waste down.
How do they go about their business though?
What is the Tube Process?
Portaledges are little areas that climbers set up to rest and sleep. When they need to go, they get on their portals and sit by the edge with their harnesses worn.
On one hand, they have a good old paper bag. This is where climbers will deposit their wastes. Inside the bag is kitty litter generously sprinkled to help with any odour problems the wastes may present.
After the business has concluded, these paper bags are rolled up and secured inside the tube. The climber can then bring the tube down with them.
It is light and can even be attached to the harness when climbing or doing business.
The Everest Waste Problem
Before creating this elegant solution, Mount Everest had a significant problem with waste. The whole mountain was littered with faeces.
Current climbers may not notice it, but it is right under their feet. The ground at the top of this mountain is filled with faeces that may have hardened for several years.
Earlier, climbers thought harsh weather conditions would sweep up their wastes. This logic made sense when fewer climbers were scaling the dizzying heights, but more climbers shut that theory down.
That is why climbers must haul their waste down the mountains with them.
Leave No Trace
Mountaineers have a famous saying that one should leave no trace on the mountains. This includes pollution, food scraps, and even poop. That is why a tube is now an important tool that helps keep mountains clean.
With that said, we hope that when you climb to high altitudes, you’ll know what to do with your waste and how important it is for the mountain you are on.
While it may be fun, mountaineering involves many risks. It is best to prepare for an accident with the right first-aid skills and knowledge, easily attainable by enrolling in first aid training.
