Hard water is simply water that contains a lot of minerals in it. These minerals are mostly magnesium carbonate, calcium, and manganese. The biggest and most obvious evidence of hard water is where soap and shampoo do not lather well, bathtubs and washing basins have a ring, laundry is dingy, and the coffee maker has some deposits of scale.

The minerals that are most commonly found in the water are calcium, manganese and magnesium carbonate. These minerals are naturally occurring, and they are usually helpful to the body.

Grains per gallon (GPG) and parts per million of mineral (PPM) are the units that are used to measure the hardness of water. 17.1 PPM is the equivalent of 1 GPG. This means that the level of hardness in water is variant, depending on the number of minerals that are dissolved in the water.

Water that measures more than 1 GPG is usually said to be hard, but in reality, if it is less than 3.5 GPG, it is relatively soft. Other levels that are used to state the hardness of water includes typically hard, moderately hard or very hard. Very hard water is usually said to be water that measures above 10.5 GP.

What are some of the benefits associated with the intake of hard water?

Calcium Intake

Intake of calcium is essential to your health. One of the greatest importance of this mineral is bone strengthening; the calcium content in the body determines the strength of the bones.

Calcium and vitamin D is usually recommended if you or any member of your family, including children, wants to have healthy and strong bones. Since calcium is one of the main ions in hard water, hard drinking water helps to add the necessary amount of the minerals in the body.

Adults lacking calcium in their body have a lot of difficulties especially in doing challenging works. This is because they have weak bones (Hypocalcemia). This leads to severe outcomes including bone breakage or even having problems in doing hard tasks that require additional effort.

Hard water will contribute a big deal of the calcium content in the body.

The research was done by WHO revealed that calcium also tends to reduce the risks of developing cancer of the rectum. Though very high amounts may lead to prostate cancer, the calcium levels in hard water are much less, hence, suitable to prevent diseases rather than cause them.

Another benefit of the calcium supplements in hard water is that they help prevent cardiovascular diseases.  Research is however still being done to determine the amounts that are suitable to prevent cardiovascular diseases.


Nutritionists also recommend an amount of magnesium intake as a preventive measure for some diseases.

The intake of magnesium is known to reduce hypertension (high blood pressure). Thus a lowering its risk.

The presence of magnesium in the body reduces the risk of diabetes and increases the heart health condition.

Schroeder’s point of view.

The first major study on drinking water was in 1960 by Schroeder (Scholar). Though Schroeder focused only on the cardiovascular diseases, he concluded that hard water is ‘healthy’.


  1. Both Calcium and magnesium are essential as a dietary need in the human body. Also, hard water has a less likely to corrode pipes if it is not excessively hard.
  2. Soft water also has a likely high chance to dissolve other metals like lead which are potentially toxic to the human health.
  3. Hard water contains less sodium that may be a risk to those who have a restricted dietary intake.

Some Disadvantages of Hard Water in Daily Usage

Hard water does not have defective effects on the health of the body. It, therefore, questions out the claims that there is a harm to the human health in using hard water.

Though it may be safe and beneficial to the human body, hard water can be a little bit disturbing when it comes to typical daily chores at home like washing, cooking, and nothing. Some of the problems associated with hard water at home include;

Some of the issues related to hard water at home include;

  • It can cause the blockage the pipes where the hard water passes.
  • Detergent and soaps required for washing will have to be more than usual. It means more to spend on cleaning soap and detergents.
  • Appliances that are in direct contact with hard water has a reduced lifespan, for instance, the scum formed on the regular boiling of water.
  • Cleaning becomes more difficult since the formation of lather takes a longer time.

Bottom Line

In conclusion, hard water is very helpful to the human body. Its positive impacts cannot be disregarded, and they completely outweigh the problems associated with hard water.

Drinking soft water denies you the valuable minerals that you can quickly gain from drinking hard water. These minerals will help boost your general health and prevent you from some illnesses.

For those who find hard water irritating when it comes to home chores, you can have soft water available at your home for purposes such as washing cutlery and preparing coffee.

You can then have hard water available for drinking purposes. This will help you benefit from the positive side of the hard water, while also avoiding the negative.
