然而,最近微博上有一个报道说,美国一个30岁女子喝小便11年,并将其涂在脸上,称“尿液疗法”对皮肤有奇效,可降血糖和胆固醇。
无独有偶。前几年,有一位女士也发现自己公公每天早上起来首先要做的事情却是喝掉自己的晨尿,而原因就是为了养生。其实,人类喝尿并不是什么新鲜事儿,自古就有这样的事情发生,中国古代一直有喝童子尿的记载和传说;不光中国人信,西方人也这么干,早在公元前50年,欧洲伊比利亚半岛的凯尔特人将其当做漱口水来美白牙齿;圣经旧约箴言中还有“你要喝自己池中的水,饮自己井里的活水”的说法。而喝尿的理由呢,有些人是为了让人变美,有些人是为了养生,甚至还有部分人为追求性快感而喝尿。比如中国人说喝童子尿可以壮阳。不过,尿液里面有什么特殊成分吗?喝尿真的可以使人变美或者养生吗?参考资料:
