No. You should not drink pee in a survival situation. Drinking urine can make dehydration worse and may cause illness. When water runs low, your priorities should be reducing unnecessary water loss, finding a suitable water source, treating it correctly, and getting help.
It is an understandable question. You are thirsty, you are worried, and you remember seeing someone drink urine on television. Under stress, something familiar can start to sound reasonable.
At Nature Reliance School, we encourage people to examine survival advice before they need it. A dramatic scene can stick in your memory. That does not make it a dependable plan.
Why Drinking Urine Is a Bad Survival Strategy
1. It puts waste products back into your body
Your kidneys produce urine to remove waste and regulate fluid balance. Urine contains water, but it also contains substances such as urea and salts. According to Cleveland Clinic’s explanation of urine, insufficient water intake increases the concentration of waste products in pee.
The familiar claim that urine is roughly 95 percent water leaves out an important detail: its composition changes. Urine produced by a dehydrated person is not equivalent to clean drinking water.
2. It can worsen dehydration
In Cleveland Clinic’s discussion of whether urine is sterile, urologist Dr. Neel Parekh warns that drinking it can increase dehydration because of its salt and waste content.
That matters when you are already struggling to replace lost fluid. Repeatedly drinking urine is not a reliable way to keep yourself hydrated.
3. It can make you sick
Poison Control advises against drinking urine and identifies nausea, vomiting, and diarrhea as possible effects. It also explains that urine is not sterile, even in healthy people.
In a survival situation, vomiting or diarrhea can mean additional fluid loss. Feeling sick can also make it harder to carry out the tasks needed to get home.
This does not mean one accidental swallow is automatically a medical catastrophe. Poison Control notes that small accidental exposures may not cause illness. That is different from deliberately relying on urine for hydration.
Survival Educators Advise Against It, Too
It is not only my opinion on this matter. Besides the various expert opinions listed here other survival authors agree as well. Land Safety and Survival, written by Alaska Marine Safety Education Association staff and published by University of Alaska Sea Grant, gives a direct instruction in its survival water guidance: “Do not drink urine.” You will find that statement on printed page 160 (PDF page 166).
That advice supports the medical guidance above. When you build your emergency water plan, focus on suitable water sources and treatment methods you understand.
What Should You Do When Water Runs Low?
Your next decision should improve your situation. Use the following approach to slow down and work through your options.
-
Use STOPA. Sit down to reset when it is safe. Think about your on-body gear. Observe your surroundings. Plan and verbalize your next steps. Actively stay alive by remembering your reasons to live.
-
Reduce unnecessary exertion. Seek shade or appropriate shelter and reconsider tasks that make you sweat without improving your situation. Account for the weather, terrain, and immediate hazards.
-
Assess water options deliberately. Check your map, known water sources, remaining supplies, and your ability to reach water safely. Avoid wandering farther into unfamiliar terrain based on a guess.
-
Treat suitable source water correctly. Follow your treatment equipment’s instructions and understand its limits.
-
Seek help early. If you are stranded or cannot reach safe water, use available communications or an emergency signaling device. Make yourself easier to locate.
For water that needs treatment for germs, CDC guidance recommends bringing clear water to a rolling boil for one minute, or three minutes above 6,500 feet. Let it cool before drinking. Boiling or disinfecting does not make water contaminated with fuel or toxic chemicals safe.
Those instructions apply to treating suitable water sources. They are not a recommendation to boil urine and drink it.
Prepare Your Water Plan Before the Trip
Carry water appropriate to the trip, weather, exertion, and people in your group. Identify refill opportunities before leaving, and bring a treatment method you have practiced using.
Think about what happens if a spring is dry, a bottle leaks, or your outing lasts longer than expected. A backup plan is much easier to build at home than when you are thirsty and tired.
The lesson is straightforward: leave urine out of your survival water plan. Put your effort into preparation, sound decisions, suitable water treatment, and getting help when you need it.
