More than 90% of the components in urine are water, but the contents of protein, amino acids, trace elements and urokinase are extremely low. Drinking urine is actually repeatedly drinking human excrement, which will only increase the burden on your liver, stomach and blood circulation, and urine also contains many bacteria and viruses. For example, just drink urine once or twice in the desert to quench your thirst. Drinking too much will make you thirsty, because urine contains inorganic salts.
