Hard water can clog your kettle, but there is
strong evidence that it helps protect your
a heart. Certain impurities in water can be very useful for
health of your body and immunity.
What is called hard water?
Hard water is simply water that contains a large
amount of minerals. These minerals are mainly
magnesium carbonate, calcium and manganese. However, stiffness may be
caused by several other dissolved metals; these forms
are bivalent or multivalent cations,
including aluminum, barium, strontium, iron, zinc and manganese. Usually
monovalent ions, such as sodium and potassium, do not cause
hardness But divalent cations tend to combine with
anions in water and the formation of stable salts. Anion type,
found in these salts, distinguishes two types: carbonate and
Carbonate stiffness due to metals in combination with
alkalinity. Alkalinity is the ability of water to neutralize acids,
attributed to compounds such as carbonate, bicarbonate,
hydroxide, and sometimes borate, silicate and phosphate. On the contrary
non-carbonate hardness is formed when metals combine with
Carbonate stiffness is called temporary because it can
remove by boiling. Non-carbonate hardness cannot be removed.
by boiling, so it is also known as constant
The clearest evidence of hard water in the faucet
is that soap and shampoo are badly washed out, baths,
washbasins and shiny parts plumbing have a raid, linen after
the washing is dirty, and deposits accumulate in the kettle.
Minerals that are most commonly found in water represent
are carbonates of calcium, magnesium and manganese. These minerals
appear in the water in a natural way since water
seeps through calcium or magnesium-containing minerals.
The most common sources are limestone (which
introduces calcium into water) and dolomite (which introduces magnesium). Usually
they are beneficial to the human body. Groundwater is often
have greater hardness than surface water.
The classic measure for measuring the concentration of calcium cations and
magnesium in water is mol / m3, in practice commonly used
degrees of hardness and milligram equivalents per liter (mEq / l). WITH
01/01/14 a standard has been introduced in Russia according to which rigidity is expressed
in degrees of hardness (° W), 1 ° W = 1/2 mmol / l = 1 mEq / l.

The benefits of hard water
Calcium is essential for your health. One of the most important
the properties of this mineral is the strengthening of bones; its quantity
contained in the body, determines the strength of the skeleton.
Calcium and vitamin D are recommended if you or members of your
Families, including children, want healthy, strong bones.
Since calcium is one of the main ions in hard water,
its use helps to add to the body the necessary amount
An adult without calcium in his body experiences
great difficulties, especially when performing complex work requiring
extra effort. This is because he has weak bones.
(hypocalcemia). The latter leads to serious consequences, including
Hard water makes a significant contribution to the overall supply
Also, studies conducted by WHO have proven that calcium
tends to reduce the risk of colorectal cancer. Though
too much calcium can lead to prostate cancer,
the level of calcium in hard water is much less, therefore its

for some diseases. Magnesium regulates about 350 cellular
enzymes in the body. These enzymes control important functions,
such as regulation of blood pressure, stabilization of the heart
rhythms and muscle contraction. Magnesium intake reduces arterial
hypertension (high blood pressure), the risk of developing diabetes and
improves heart health.
WITHогласно исследованиям ВОЗ в 2009 году: «Низкий уровень магния
has been associated with hypertension, coronary heart disease, sugar
diabetes and metabolic syndrome. “
In one meta-analysis, researchers concluded that the additive
magnesium per 100 mg was associated with an 8% reduction in the risk of developing
stroke, especially ischemic strokes.
In general, future research in this area will be able to give us
better understand the importance of magnesium for protect our hearts.

In addition, hard water leads to less corrosion of pipes;
