Can a person drink their own urine to survive. I was watching a documentary that said a man did this for a while until his urine turned toxic. How long does that take?
Yes, absolutely. I do it frequently while hiking. Try to find a source that is clear and running if possible. If you have to use still water, boil it for at least a minute or 2 before drinking it. You can also filter out any bigger particles with a bandanna or other type of filter medium.Thank you for explaining that. It makes a whole lot more sense to me to get water out of a river or creek and boil it to remove impurities. That can be done, can't it?
Absorption of water is by passive diffusion. Water travels across a permeable membrane from an area of high concentration to an area of low concentration, moving toward equilibrium.However, I have heard that you can give yourself an enema with seawater (salt water) and survive.
