What water is healthy water? How to drink water is safe.

The physiological function of water is the difference between "stagnant water" and "living water". Clean water and safe water mainly emphasize the "thirst quenching" function and the "safety" of water, while going up a storey still higher, a healthy water emphasizes the "health" and physiological function of water on the basis of the "thirst quenching" function and "safety" of water. The author believes that healthy water, as a complete scientific concept, should meet the following seven standards:

1. Does not contain toxic, harmful or odorous substances;

2. The hardness of water (calculated by caco3) is moderate (50-200mg/L);

3. The mineral content required by human body is moderate (including calcium content ≥ 8 mg/L);

4. The 4.ph value is neutral and slightly alkaline;

5. The contents of dissolved oxygen and carbon dioxide in water are moderate (dissolved oxygen in water ≥6mg/l, carbon dioxide10-30 mg/L);

6. Small water cluster (one of the indicators of water activity);

7. Physiological functions of water (permeability, solubility, metabolism, etc. ) strong.

The above seven points can also be simply summarized as the following three points:

First, there is no polluted water-non-toxic, harmless and tasteless;

Second, there is no degraded water-living water;

Third, water to meet human physiological needs. It contains some beneficial minerals, neutral water, etc. )

To meet the first point, only "clean" drinking water, to meet the first and third points, and "safe" drinking water. Only by doing three things can you achieve health by drinking water.
