Uncle Jiu recently browsed the circle of friends
and saw such a notice:

The comment area of the notice was very lively
Everyone said something to me
started a crusade against " tap water ":
"No wonder when the tap water is boiled recently, it is full of white floating objects, which is definitely harmful to health."
"Yes, when I turn on the faucet, the water flow remains white for a minute, and it smells like disinfectant, so I dare not use it."
"Tsk tsk, the high incidence of kidney disease in our country must be related to the tap water"
"This chlorine sounds like a chemical substance, and it may cause cancer"
...


Tap water is the main source of daily water
But many people have doubts about the practice of adding chlorine
So
Why should chlorine be added to good tap water?
In fact, this is done
for public health
It takes a long time for tap water to reach residents' homes from the source
and more than ten kilometers of pipelines
During this process
the water source may be contaminated if it is not After any treatment
the end water may contain impurities, harmful microorganisms etc.
affecting water safety
In response to this situation
the current common solution around the world is adding chlorine
chlorine immersed in water
will be converted into hypochlorous acid
kills bacteria and pathogenic microorganisms in the water

but the microorganisms and organic matter in the water
will only consume part of the chlorine
The remaining chlorine is called "residual chlorine"
Residual chlorine is not just normal
It is also necessary
A certain amount of residual chlorine must be ensured in drinking water
has the function of continuous disinfection
can help inhibit bacteria in water pipes

You don’t have to worry too much about this problem
First of all,
the "Hygienic Standards for Drinking Water" implemented in our country
clearly stipulates for water plants:
The minimum chlorine content of factory water is 0.3 mg/L
terminal water has the lowest chlorine content
.05 mg/L
Regulatory authorities will also conduct regular sampling monitoring
to protect the safety of residents’ drinking water
other
The toxicity of chlorine to the human body is closely related to the dose.
The World Health Organization proposes
Residual chlorine in water No visible toxic level is 15mg/kg per day
That is to say
Even if you consume dozens of liters of tap water a day
it will not reach the amount of chlorine poisoning

In addition
by Depending on the distance between the user and the water plant
The content of residual chlorine in the pipe network also varies
The chlorine smell of tap water in some people's homes may indeed be heavier
If you don't like it If you like the taste of chlorine or have a grudge
you can easily remove chlorine by simply heating the tap water (boiling for 1-2 minutes)
There is no need to let it sit for a while before drinking


Medical survey data show
The number of patients with chronic kidney disease in China
has ranked first in the world
The total number is close to 120 million
The incidence of chronic kidney disease in adults is 10.8%
The increase in the incidence of kidney disease
has also accelerated the development of uremia
The situation is not optimistic
The high incidence of chronic kidney disease
is related to complex factors such as obesity, high blood pressure , hyperlipidemia, diabetes ,
high uric acid, misuse of drugs, smoking and other complex factors
It is closely related
but many people are pointing the finger at water quality
It is reported online
that after boiling the tap water in some areas
there will be some white fluff
Or scale has precipitated in the kettle
It means poor water quality
If you drink it for a long time
it will lead to kidney stones

In this regard
Guangzhou Center for Disease Control and Prevention
has conducted relevant testing on tap water and mineral water
most It was finally discovered that after boiling water, white floating flocculation or scale will be formed. These substances are mixtures of calcium carbonate, magnesium hydroxide, etc.
. The regional geology and water quality are special
There may also be manganese, silicon and other minerals
Currently there is no medical evidence proving that
scale is related to kidney stones
On the contrary
A European disease survey showed
There is no significant difference in the incidence of urinary system stones between the UK with hard water and the Netherlands with soft water
Therefore, if wants to find out the "murderer" that damages the kidneys , we must start elsewhere The kidneys are an important sewage system of the human body Protecting kidney health cannot be ignored. But sometimes some inadvertent behaviors can cause damage to the kidneys How many of the following six habits do you have? Long-term high-salt diet will increase the burden on the kidneys In mild cases, it may cause electrolyte imbalance In severe cases, it may cause kidney damage The main organ of the human body to metabolize drugs is the kidney On the one hand Long-term medication will put pressure on the kidneys causes damage On the other hand some nephrotoxic drugs themselves should be used with caution For example: Aristolochia type of traditional Chinese medicine, chemotherapy drugs, some analgesics If used indiscriminately, it may cause serious consequences Long-term lack of rest and staying up late may lead to liver and kidney dysfunction more susceptible to nephritis diseases Clinical data also shows long-term overwork leads to 70% of nephritis cases Insufficient hydration. will lead to decreased urination Toxins and waste accumulation in the body for a long time may cause kidney stones, hydronephrosis and other kidney diseases high blood pressure, hyperlipidemia, high uric acid, diabetes and other chronic diseases Diseases may cause kidney damage If the patient takes it lightly and does not adhere to monitoring indicators for a long time, it may cause reduced kidney function and kidney damage How to protect kidney health? Uncle Jiu is here to give you advice The high incidence of kidney disease is indeed a problem worth vigilance But people should believe in medicine and use the correct way to solve it rather than being swayed by rumors Water "chlorine disinfection" has a history of more than 100 years. "Chlorine disinfection" is still the most mainstream disinfection method at present. The residual chlorine level in tap water in my country is also in line with the national drinking water hygiene standards. You don't need to worry too much.

How to protect kidney health?
Uncle Jiu is here to give you advice

The high incidence of kidney disease
is indeed a problem worth vigilance
But people should believe in medicine
and use the correct way to solve it
rather than being swayed by rumors
Water "chlorine disinfection" has a history of more than 100 years.
"Chlorine disinfection" is still the most mainstream disinfection method at present.
The residual chlorine level in tap water in my country is also in line with the national drinking water hygiene standards.
You don't need to worry too much.
You can boil it for drinking with confidence.
