凉开水是最佳饮料 对人体健康而言，最理想的饮料还数凉开水。经研究发现，开水自然冷却后，水中的氯气要比一般自然水降低50%，水的分子结构会发生某些变化，水的表面张力、密度、导电率等理化性能都有所改变，其生物活性比自然水要高出4-5倍，与生物活细胞里的水十分相似，因 Cold water is the best drink For human health, the best drink is also cool water. The study found that natural cooling water, the chlorine in water than the general natural water to reduce 50%, the molecular structure of water will change some of the water surface tension, density, conductivity and other physical and chemical properties have changed its biological 4-5 times more active than natural water, which is very similar to water in living cells
