不可或缺的水水是和人类最亲密的物质之一,人体的70%由水构成,一切新陈代谢都是在有水的环境下进行。水是由氢、氧2种元素组成的无机物,水分子之间由氢键连接。它的存在减缓了水变热和变冷的速度。因此在有水的环境中,温度相当稳定。这一特性也让人的体温在外界气温变化时可以保持恒定。水中有近10种微量元素是人体所必需的。然而,全世界80%的疾病也是由饮水污染造成;有12亿人口因饮水被污染而患上多种疾病。水对于健康的重要性不言而喻。
Indispensable water is one of the closest human beings, and 70% of the human body is made up of water, and all metabolism is done in a watery environment. Water is composed of hydrogen, oxygen, two kinds of elements of inorganic substances, water molecules connected by hydrogen bonds. Its presence slows down the rate at which water heats and chills. So in a watery environment, the temperature is quite stable. This feature also makes the body temperature in the external temperature changes can be constant. Nearly 10 kinds of trace elements in the water are necessary for the human body. However, 80% of the world’s diseases are also caused by drinking water pollution; 1.2 billion people suffer from various diseases caused by drinking water pollution. The importance of water for health is self-evident.
