Is it harmful to drink tap water for a long time?

Whether in cities or rural areas, the water we drink at home is tap water that has been disinfected. However, in some areas, people still drink groundwater directly. Is it harmful to drink tap water for a long time? If tap water is not treated, it will contain many harmful substances. It is understood that there are more than 700 kinds of these harmful substances. Even if it is boiled, various bacteria will remain, which will still be harmful to the body after entering the human body.

Four major hazards of tap water

First: Let's look at a set of data: According to tests by the World Health Organization, there are as many as 25 carcinogens in tap water, and an additional 12 stone-forming substances. Severely polluted tap water contains more than 700 harmful substances. 90% of stone diseases such as urinary stones and gallstones are caused by drinking unhealthy tap water. Among every ten cancer patients, 5 are related to unhealthy drinking water. From the above data we can see how harmful tap water is.

Second: Most friends think that boiled water is non-toxic. Boiling water can kill more than 80% of bacteria in water. But have we ever thought about it? After boiling, bacterial residues and dead bodies will still remain in the water and will also enter the human body when drinking. And these bacterial residues will become the source of fever in the human body.

Third: The initiator of cancer. Boiling tap water kills 80% of bacteria, but there are pros and cons. After water is boiled, all the oxygen in the water is lost. The oxygen needed for human metabolism comes from cells. Water accounts for 70% of cells. Long-term drinking of oxygen-deficient water will cause cell hypoxia. The oxygen-deficient cells will become deformed and may become cancerous over time.

Fourth: Some residents have realized the harm of tap water to the human body and started to dig groundwater. Groundwater is originally the healthiest water resource. However, due to the infiltration of large amounts of industrial wastewater, heavy metal water, etc. into the ground, the groundwater has become deeply polluted, especially the calcium and magnesium content exceeds the standard. Drinking this groundwater will increase the incidence of coronary heart disease, cardiovascular and cerebrovascular diseases, stones and other diseases.

2What harm does residual chlorine in tap water cause to the human body?

The hazards of residual chlorine in tap water to human body are as follows:

1. Chlorine is very harmful to the human body: it can irritate the eyes, nose, throat and upper respiratory tract, etc. It causes acute pulmonary edema and can paralyze the nerves in the respiratory area when the concentration is high. Long-term inhalation of low concentrations of chlorine can cause chronic poisoning. When chlorine is added to water, it can cause your skin to bleach, peel and cause allergies. Chlorine produces carcinogens such as chloroform when heated

What effect does water containing residual chlorine have on washing vegetables, fruits, grains, etc.: Chlorine will destroy the vitamins, minerals and other nutrients in vegetables, fruits and grains, and seriously affect the body's absorption of nutrients.

What are the dangers of bathing in water containing residual chlorine for a long time: When bathing in water containing residual chlorine, 40% of the total chlorine in the bathroom is inhaled through the respiratory tract, and 30% is absorbed by the skin, which is 6 to 8 times the chlorine that normally enters the human body through drinking. In mild cases, itching occurs, and in severe cases, the risk of cancer increases by 30%.

2. Boiling tap water is more harmful: after boiling tap water, the organic decomposition in the water will produce carcinogens such as chloroform. The chloroform content will increase 3 to 4 times that of tap water. If the residual chlorine cannot be removed, the carcinogens in the coffee, tea and soup we drink every day will increase 3 to 4 times after heating.

3. What diseases may be caused by long-term drinking of water containing residual chlorine: heart disease, coronary atherosclerosis, anemia, bladder cancer, liver cancer, colorectal cancer, hypertension and allergic symptoms.

4. The harm of residual chlorine to children: When bathing children with tap water, chlorine will cause their hair to become dry, broken and split, and will also cause their skin to bleach, peel off and cause allergies. When chlorine interacts with organic matter such as sweat, it can easily cause nitrogen trichloride in the surrounding air, which can easily damage the eyes and throat. When chlorine is inhaled into the lungs through the respiratory tract, it will damage respiratory cells and easily lead to asthma and emphysema.

5. What effects does residual chlorine have on pregnant women: If pregnant women drink tap water containing residual chlorine for a long time, it will affect the growth of the fetus's heart and lungs. It may also cause arrhythmia and lung dysfunction in newborns.

6. The harm of residual chlorine to the elderly: it can cause atherosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, hypertension, etc.
