  • Hopefully this never happens to you,

  • but, let's say you found yourself

  • in an extreme situation.

  • You're out of food and water,

  • and the only liquid nearby is, well

  • (zipper zips)

  • your own.

  • (liquid splashing)

  • You've heard of astronauts drinking urine in space,

  • but they have high tech filtration systems,

  • and you don't.

  • Your best option is to drink it straight

  • like Aron Ralston did when he was trapped

  • in a canyon for 127 hours before escape and rescue.

  • If Ralston did it and survived, so should you, right?

  • Depending on the environment,

  • an adult can survive up to one week without water,

  • and three weeks without food.

  • But that window quickly narrows

  • when you're dehydrated, sick, or both.

  • For that reason, the Army has a field manual

  • which has a do not drink list for such an occasion.

  • The list includes, fish juices,

  • blood, alcohol, sea water, and, yes, urine.

  • In fact, when you break it down,

  • urine isn't that much different from sea water.

  • It's usually around 95% water with a mix

  • of byproducts including sodium, chloride, and urea.

  • Sea water by comparison is 96.5% water,

  • and 3.5% sodium and chloride.

  • So drinking urine is basically like drinking sea water.

  • It's going to dehydrate you,

  • which is the opposite of what you want.

  • To make matters worse,

  • if you keep drinking it, the severe dehydration

  • can trigger abnormally low blood pressure.

  • Low blood pressure means less blood flow to vital organs

  • like your heart, lungs, and kidneys,

  • which can be damaged or fail as a result.

  • Not good.

  • Adding to your trouble is that urea.

  • In a word, urea is waste.

  • It's not supposed to be in your body.

  • That's why your kidneys filter it

  • out of your blood and into your urine,

  • which ordinarily then leaves your system.

  • But if you drink the urine instead,

  • your kidneys have to work harder

  • to filter out that extra urea,

  • which could lead to kidney failure.

  • Again, not good.

  • Suffice it to say, drinking urine

  • may be your kidneys' worst nightmare.

  • And to top it off, there's the bacteria.

  • Contrary to popular belief, urine is not sterile.

  • According to one study,

  • it contains at least 85 different bacterial species.

  • Some of the most common are ones like staphylococcus,

  • which is known to cause food poisoning,

  • and actinomyces which is commonly found in gum infections.

  • So unless you want sore gums, nausea,

  • and failing organs while you search for rescue,

  • best avoid that urine cocktail all together.

  • What's the weirdest survival tip that you know?

  • Let us know in the comments, and thanks for watching.

Hopefully this never happens to you,
