Do you drink urine in critical situations outdoors?

We often receive the following question: Is drinking filtered urine in extreme conditions to supplement body fluids? The confusion surrounding this issue is understandable because there are always admirable drinking legends on the rivers and lakes.

Is it safe to drink urine directly?

It is said that drinking your own urine in the wild without water can save you from dehydration. In fact, it is wrong to do so. Because urine can not only not add body fluids, but also play the opposite role - to accelerate the body dehydration. So, it's really No Zuo No Die to drink urine.

It is important to remember that pee is the physiological mechanism by which the body excretes excess water and soluble waste. Most of the urine is water, the other is mainly dissolved salts, minerals and trace toxins discharged from the liver. The higher the degree of dehydration, the higher the concentration of these contaminants in the discharged urine. If you are in a state of survival, the body is basically extremely dehydrated and the concentration of pollutants will only be higher.

It's been a trick to take a risk. Drinking urine to get these contaminants into your system can cause toxins to accumulate. In the same way, drinking sea water is also dangerous - the more you drink, the more dehydration becomes serious - too much salt will take away moisture from the cells because of the osmosis effect.

Even so, drinking urine may not cause you to get sick. A healthy body full of fluids drank two or more cups of his own "cocktail" (the urine hasn't turned gold yet) will not be harmed. 95% of the urine is water, it is impossible to achieve complete sterility, but it does not contain harmful bacteria that can make you sick immediately. These harmful bacteria often appear in the wild water sources and are generally contaminated by feces.

Can an outside user filter drink urine?

Continuing with the egg, the answer is still not - the small spark of the collision of thoughts is again extinguished. Dissolving salts, ions, molecules, such as urea in the urine, these are too small to be filtered out of the user's filter or even the water purifier. Other water treatment methods, such as ultraviolet radiation and chemical treatment, can only kill bacteria and cannot deal with these molecular-level pollutants in the water.

The only way to safely drink urine (when you are in a state of survival and urine is your only source of water) is to separate these contaminants or to reduce their levels to negligible levels. There are two methods: First, reverse dialysis, using high pressure to allow water to penetrate the membrane that only allows water to pass through, and second, distillation, which essentially causes water molecules to evaporate and then condenses into another container. Although these two methods can separate drinking water, it is more difficult to remove the taste and smell of urine from water.

Finally, we really do not recommend drinking urine, especially in critical situations. Drinking urine, such a fearless action, can neither add body fluids nor show you the flashy “Bethes” spirit.
