Hard Water and Heart Attacks

Can you lower your risk of heart disease by drinking hard water? Perhaps, say Finnish researchers. In a study involving the death records of roughly 19,000 Finnish men, they noticed a considerably lower incidence of heart disease in the western and southern regions of the country where water hardness was highest. Researchers concede there is not an ironclad association between the two factors, heart disease and water hardness. Even so, the study revealed that for every unit increase in the hardness of local water, the risk of having a heart attack fell by 1 percent.
