Water hardness, in simple terms, refers to the concentration of mineral salts such as calcium and magnesium in water. These minerals mainly come from the natural interaction between groundwater and rocks. Depending on their content, water quality is divided into soft water and hard water. So, what are the hazards of high water hardness? When the water hardness exceeds the appropriate range, especially when it is too high, it will have a series of negative effects on our lives, health and the environment. Erun Environmental Protection Water Quality Testing Instrument and Equipment Manufacturer, the total water hardness, alkalinity, COD, metals, chloride ions, ammonia nitrogen, phosphate and other parameters can be tested.

1、Health hazards: Cardiovascular and nervous system diseases: A survey by the World Health Organization shows that 80% of human diseases are related to water. Among them, long-term drinking of high-hardness water is pointed out to be likely to cause cardiovascular, nervous, urinary and hematopoietic system diseases. This is because excessive calcium, magnesium and other minerals accumulate in the body, interfering with normal physiological functions.
Digestive system problems: Hard water may irritate the gastrointestinal tract, leading to symptoms such as indigestion, abdominal pain, and diarrhea. Especially for people who already have gastrointestinal dysfunction, hard water will aggravate their discomfort.
Urinary system stones: If the rich calcium in hard water cannot be effectively absorbed by the human body, it is easy to deposit in the urinary system, increasing the risk of stones and causing difficulty and pain in urination.
Skin and hair problems: When bathing, hard water can make your skin feel dry and tight, accelerating skin aging. It can also damage your hair, causing it to become dry and brittle.
Tooth damage: Long-term drinking of hard water can easily cause mineral deposits to form on the surface of teeth, leading to tooth discoloration and corrosion, affecting oral health.
2、Inconvenience in daily life
Cooking and eating: Hard water tastes bad after boiling, and scale will form at the bottom of the pot, affecting the flavor of tea, soup, etc，and also reducing the quality of meals.
Cleaning problems: Hard water not only consumes more detergent when washing clothes, but also makes clothes hard and discolored, and leaves a residual detergent smell. Similarly, water stains and spots on tableware and sanitary ware are difficult to remove, increasing the workload of cleaning.
Household equipment wear and tear: Minerals in hard water can accumulate as scale inside household appliances such as water heaters and washing machines, reducing equipment efficiency and shortening their service life, while increasing energy consumption and safety risks.
3、environmental impact
Agriculture and ecosystems: Using hard water for irrigation can increase soil salinity, destroy soil structure, affect crop growth, and thus endanger the balance of the entire ecosystem.
Water resource cycle: Excessive mineral content in water will limit the water’s self-purification ability, affect the living environment of aquatic organisms, and thus interfere with the natural water circulation system.
In summary, the harm of high water hardness is not only related to personal health, but also affects family economy and ecological environment. Therefore, raising awareness of water hardness and taking appropriate measures to soften water are important links in ensuring the quality of life.
