饮用纯净水不宜连续长期饮用。原因如下： Drinking pure water is not suitable for continuous long-term consumption. Here's why: 1、生命是在含有一定矿物质的水环境中起源、进化和生存的，人类在400万年进化过程中，喝的是水“溶液”而不是水“溶剂”(纯H2O)，不含矿物质的水对于生命是不利的。 1, life is in a certain minerals content of the water environment in the origin, evolution and survival of human beings in the process of evolution in 4 million, was drinking water "solution" rather than "solvent" (pure H2O), does not contain mineral water is bad for life. 2、纯净水由于“至纯”(去除了有益人体健康的微量元素和矿物质)而失去了积极生理功能的活性，变成了功能退化的“死水”。长期饮用容易引起四肢无力、精神不振等亚健康问题，尤其对胎儿的发育和儿童的成长不利。美国一位研究水的资深博士用大量翔实的资料指出：饮用水最理想的溶解性总固体含量是300mg/l，总硬度是170mg/l左右，同时其pH应为偏碱性，这种水对防治心脑血管疾病是颇有裨益的。很多发达国家都把饮水硬度定为不能低于60mg/l。 2, pure water because of the "pure" (in addition to the trace elements and minerals that are good for the health of human body) lost the positive function of activity, turned into a functional degradation "dead". Long-term drinking can easily cause the problems of sub-health, such as weakness of the limbs and mental retardancy, especially for the development of the fetus and the development of children. The water for a research senior doctor with a large number of informative data points out: drinking water is the most ideal soluble total solid content is 300 mg/l, total hardness is 170 mg/l, the pH value shall be the alkaline at the same time, the water is useful for the prevention and treatment of disease of heart head blood-vessel. In many developed countries, drinking water is not less than 60mg/l. 3、纯净水是弱酸性水(pH为5～7)，长期饮用能破坏人体正常的酸碱平衡关系，导致人体酸性化。美国医学家、诺贝尔奖获得者雷翁认为：酸性体质是百病之源。 Pure water is weak acid water (pH 5 ~ 7), long-term consumption can destroy the normal acid and alkali balance relation of the human body, cause human body acidity. According to American medical scientist and Nobel laureate reon, acid is the source of disease.
