You've seen Bear Grylls do it. You heard Patches O'Houlihan proclaim his affinity for it (if you watched "Dodgeball", anyway). Chances are, you figured it was a last resort for survival if you were ever out of water and needed a drink.
"Can I drink my own urine?" Sure you can. But the question is wrong, more importantly "should" you drink your own urine when you have been without it for a period of days? No. Never. Ever.
Who's this douchebag to be telling me not to drink my own pee to survive? Bear Grylls does it and he don't get hurt! Bear Grylls also dives headfirst into ice cold water, tries to rob honey bees in the desert -- getting his eyes swelled shut, and eats caterpillars that might well be poisonous; causing him to have to squirt over the side of a waterfall. Admittedly, it'd surely surprise the people below, probably be fun at parties, but it's not good if you have to try to live through an ordeal. So who am I?
I'm Shawn. I've been practicing Wilderness Survival and Living Skills for better than 20 years, I've taught privately and at a local Community College here in KY. I hunt, I fish, I hike, I camp (car camping, tent camping, and bare essentials camping) I'm not famous. I'm not rich. I'm not really even very attractive. But, I spend a lot of time researching and practicing woodsbumming techniques, and survival methods. And, before I started college, I spent a huge chunk of my time eating stuff that would make the neighbors (and family members) gag. I've never been to Africa. I've never been to Alaska. I've never been to the desert. Why? I don't want Malaria. I can't afford the trip to Alaska. And the desert is just too frigging hot.
Now, let's talk about that pee.
Why shouldn't you drink your pee in a low or no water situation (doesn't even have to be the desert. During Hurricane Katrina people didn't have potable water.)? Think about it: If your body wanted it in the first place, it'd keep it. Urine is one of the ways your body flushes toxins. Your wee-wee is your body's toilet.
The more water you go without, the more concentrated your pee becomes. Which means the waste products are more concentrated. Why would you want to feed your body something it clearly didn't want to begin with? Let alone in a stronger formula?
One of the main components of urine is salt. Salty food and drinks leech salt from your body, water is required to dilute the salts.
No doubt you've seen Les Stroud make a solar still and pee in it. Then drink the water produced by that process. Which is perfectly fine. If you like waiting 24 hrs for a miniscule amount of water. In an arid climate or a desert climate, the human body can require up to a gallon of a water an hour, depending on the level of physical activity. A few drops aren't going to help you. If anything, they'll only make you more thirsty than you were.
Your safest bet, if you are ever caught in a low or no water situtation is to move only during the coolest part of the day. Rest as much as possible. And stay cool/shaded.
