据说是英国人脱发的头号诱因
苏格兰的水特别软,他们不脱发,但脱牙。Which do you hate more?
这里烧个水,锅里都是白色的 沉淀。 家里的TAP上一看都是痕迹,
这样吃下去的水,结实应很厉害吧。
所以想要软化一下。
我家软水系统和净水系统是分开的。喝的水只是滤过了,没软化。软化过的水含高钠,不健康。
英国的话看此图:
如果是伦敦的话,整个伦敦都在硬水区里,
自西北向东南越来越硬,但是硬水对身体有坏处的传言没有确凿科学证据,其实硬水对身体有好处倒是有少量证据:
“The World Health Organization says that “there does not appear to be any convincing evidence that water hardness causes adverse health effects in humans”.[1] In fact, the United States National Research Council has found that hard water actually serves as a dietary supplement for calcium and magnesium.[9]”

这图够清晰的。看来软化和饮用还是要区别开来。
