Tag: Repeatedly boiled water

According to a 2020 study in The Journal of Water and Health, frequently boiling clean, sanitary tap water poses no significant health risk. This dispels the common concern that repeatedly boiled water is bad for you due to concentrated contaminants, though it can affect taste and may not be recommended for infants.

While a single boil effectively disinfects water by killing pathogens, repeated boiling causes a portion of the water to evaporate, which can concentrate dissolved minerals and alter its chemical composition. Discover the science behind why you can't use repeatedly boiled water for optimal health and taste.
