Hard Water vs. Soft Water & Cardiovascular Disease

I love water! In fact, I prefer it to any other beverage. When I don’t drink water I’ll usually have an ice tea but my preference is almost always water. It quenchs my thirst, makes me feel great and cleanses my body, not to mention it’s the beverage of choice if you’re trying to lose weight.

However, what I can’t stand is that in the area that I live, the water is hard. What that means to us is that our faucets and shower heads get a build up of calcium on them that we then have to remove by soaking in vinegar. It looks ugly until removed.

I had taught a culinary class at a womens home several months ago and she had mentioned to me that they kept having to replace their ice machine, dishwasher and washing machine because it wasn’t running properly until they found out it was due to the hard water in our area and put in a soft water filtering system. So yesterday when I had an appliance technician out to fix our ice machine I mentioned what she had told me. His reply was, “yes it will function better however, with health hazards.

After he left I got online to read about the health benefits and hazards of hard and soft water. What I found out surprised me so much that I thought I would share my findings with you.

Hardness in water refers to the amount of calcium and magnesium, or calcium carbonate in the water. The more calcium carbonate, the harder the water; the less, the softer the water.

Numerous studies have been conducted over the years linking the relation between mortality from cardiovascular disease and treated water supplies. It’s been found that the calcium and magnesium in hard water reduces the risks of heart attacks and strokes.

One study I read compared the health records of 11,400 Wisconsin male farmers who drank well water from their own farms. The farmers who drank soft water suffered from heart disease, whereas, the farmers who drank hard water were, for the most part, free of the problem.

Overall in every study I read, the findings were that the harder the water the less heart disease deaths.

Hard water contains TDS (total dissolved solids) minerals. TDS is a measurement of all the minerals in drinking water. TDS not only includes calcium and magnesium (the hardness factors), but also zinc, copper chromium, selenium and so on. People who drank water higher in TDS had lower death rates from heart disease, cancer and chronic diseases than people who drank water with low amounts of TDS.

Several studies have also been published on sodium in drinking water and its effect on blood pressure. Most often, water softening techniques add sodium to the water replacing significant amounts of calcium and magnesium. There are procedures however, that do not add sodium but still reduce the hardness of the water.

Softened water is unhealthy to drink – not because of the sodium, necessarily, but because of the lack or lower amounts of calcium and magnesium in the water. If you are currently using a water softener, have a separate cold water line installed for your drinking water, and on this line install a proper filter unit.

If you have high blood pressure, softening your water can indeed raise your blood pressure even more due to the higher sodium levels. So you may want to discuss this with your doctor to find out how it may affect you.

Although soft water feels silky on your skin and hair, when bathing it’s seems almost impossible to rinse the soap off. Leaving your hair feeling oily and unclean even right after you’ve washed it. Hair washed with soft water will have little to no volume and fall flat on your head.

Basically, the only drawback I’ve found to having hard water is those unwanted calcium deposits left on my faucets and hardware over time, which can be easily removed even though it’s an inconvenience.

After reading numerous pieces of literature on this subject I’ve come to the conclusion that I’ll leave my hard water as is. It may not be as good for my appliances (although adding specific rinses will help alleviate the problem) but it’s much better for my health.

I was unaware of these findings. Were you familiar with this? If so, what experience have you had with hard vs. soft water and what changes if any have you made in your home?

  1. Interesting. I didn’t know about this but perhaps this was the reason the doctor advised my father to cut down on his water intake (we have soft water)for his high blood pressure.Surprising enough, after a month, his blood pressure improved immensely.The doctor did advise that he stay out of salty food when he cut back on water.

  2. They say that if you have soft water you can drink bottled water and that would provide you with the loss of minerals in your soft water as well as the added sodium.

    You might have your dad ask his doctor about that. Possibly drinking bottled water would be an alternative. I’m not a doctor but I would think that water is great for the body so long as it’s not loaded with sodium but not knowing your dads situation or being a doctor I couldn’t say for sure.

    Had I not had the service technician over to my home I doubt I would have ever discovered these facts.

    Thanks for your post Alisa. Have a great day!

  3. A water softener is a good investment but it is definitely important to note that drinking soft water is not the best for you! Thanks for the post!

  5. Simple solution which is what we did.
    Water softener installed in our house does not soften water to the kitchen taps, which we use for drinking, while all other pipes have softened water. Our calcium content is 400 ppm, which is unusually high but considered normal in Belgium. For comparison Thames Water in Surrey UK water is 236 ppm.

    Before my skin and hair looked dull and my hair lost shine and resembled straw. After the softened had been installed my hair regained shine and looks fine.

    There are pros and cons for hard & soft water. Wash with soft and drink with hard.

  6. Good sharing, I would recommend Visa Cardio-nautical Drink for those who are suffering from heart disease.

  7. I spent 35 years as a water treatment plant operator. My own feeling, based on many scientific studies, is that soft water definately is associated with a higher risk of cardiovascular disease. For that reason we did not soften our municipal water. I would advise customers to install a home softener only on the hot water side. You would still get a mixture in places like the showers and such but the cold water, drinking water and hose bibs, would still be hard.

  8. You would use a high quality reverse osmosis drinking solution. The soft water would be a great addition….you dont drink soft water. Article means little.
