水软化剂和你的健康
水软化剂是否造成健康风险？

对于井水，一种估计盐基水软化的钠的量的方法是将井水的平均水平为278mg / L（尽管变异可以是宽的，但从46〜1,219 mg / L.据估计，17％的家庭含水良好水分超过400mg / l）。作为一般规则，水越硬，钠水平越高。

在内科档案中出版的研究人员表示，软化水中钠的量可以变化。实际上，这种可变性取决于水硬度（Yarows等，1997年1月，“水钠浓度来自软化剂”）。

According to a researcher writing in the Journal of the American Dietetic Association ("Sodium content of potable water: dietary significance," by G.C. Korch, January 1986), Americans are taking in more sodium than required for physiologic functions and that "the contribution of drinking water as a source of sodium may be overlooked" (emphasis added by the author of this Freedrinkingwater.com article). Scientists estimate that water account for approximately 10% of a person's daily sodium intake, and hence people should know the sodium content of their water supply. For people who are on sodium-restricted diets, they must avoid drinking softened water using traditional salt-based softening technology or just tap water (approximately 42% of the United States water supplies have excess sodium). For people on the sodium-restricted diet, they should drink purified, filtered water. For hypertensive patients, bottled water may not even be safe from sodium—it is well known that about 25 percent of all bottled water come straight from the tap but they are sold as pristine "spring water"!

我们建议人们用反渗透（RO）水净化系统在家中瓶装自己的过滤，纯净的水，使他们确切地知道他们穿着瓶子的水。对于高血压的人或简单地携带钠摄入量，饮用过滤，纯净的水是最好的。

在软化水中使用钾代替钠

虽然水软化工业声称添加了水软化期间的钠是如此微不足道，但它不会产生健康问题，医生和一些消费者团体建议人们使用切换到基于钾的水软化。但这仍然很难进入现实，因为使用氯化钾（KCl）代替氯化钠盐（NaCl），但虽然可以花费三到四倍。
