But if you kept recycling urine by urinating and drinking it multiple times, wouldn’t those minerals eventually build up until the urine was no longer safe? Over several days, your urine would become saturated with minerals. And drinking it would really tax the kidneys, whose job it is to flush unwanted minerals and toxins from the body. Drink urine long enough and you may go into kidney failure. On a related note, you may have heard that in some cultures, urine is used as medicine. There’s no hard evidence that urine has any curative powers, which doesn’t mean it has none. But urologists tend to believe that whatever healthful powers drinking urine has would be negated by toxic buildup in the kidneys.
但是,如果你一只排尿和并喝尿很多次,這些礦物最不會積累嗎?那直到尿液不再安全?過一些天,你的尿液會變成飽和的礦物質。這時再喝會加重腎臟的負擔,而腎臟的功能是排掉身體不需要的礦物質和毒素。如果長時間喝尿,你可能會腎功能衰竭。在一些相關的記錄,你可能已經聽說,在一些文化中尿可以當做藥物。沒有確鑿的證據證明尿有任何療效的功能能,但這并不意味著它沒有治病的功能。但是,泌尿科醫生往往認為健康的人無論喝什么樣的尿都會在腎臟中積聚毒性。
