          The Vast Knowledge on Water Drinking
        
        
          Many diseases are caused by drinking impure water: 2 million people die from consuming impure water a year [WHO]. Purified water is
        
        
          colourless and without any abnormal smell. Contaminated water causes skin rash, nausea and headaches; may even induce cancers, heart
        
        
          diseases, nerve damages, etc. Tap water contamination is from the source, the treatment plant or water storage tanks; by carcinogens or
        
        
          mutagens - no effective filtration. Mineral water is from springs or wells, natural water, from springs or wells but with little processing. Drink
        
        
          water between meals but not in the evenings till next morning. Boil water for 3 min to dispel chlorine and other impurities. Excessive water
        
        
          overloads the heart; depletes sodium: dizziness or convulsion results. Avoid drinking re-boiled water (nitrosamines accumulate); overnight
        
        
          water in thermos flasks; water continuously boiling; water used for steaming food; water with prolonged standing in the air; water left standing
        
        
          for prolonged periods; water not thoroughly boiled. Drink more when having a flu or cystitis or having active exercises. It pays to observe all
        
        
          these simple rules!
