Drinking water boiled by an electric kettle for a long time is not only poisonous but also carcinogenic? 2 suggestions to listen to

Water, as the source of life, escorts the normal life activities of human beings. Ensuring that the human body has sufficient water intake every day can ensure the normal operation of various organs.

Studies have shown that drinking more hot water is very beneficial to human health, because after boiling, various harmful impurities such as bacteria and microorganisms in the water are removed. Remove. Because of this, many water boiling tools have entered people’s field of vision.

With the popularity of water dispensers, the way of boiling water has undergone a qualitative change from open fire heating to electric heating. In recent years, electric kettles have become popular again. water boiling tool.

However, some people say that long-term use of an electric kettle to boil water may cause cancer;

Some people also say that most electric kettles are made of high-manganese steel. Manganese has a strong toxic effect on the human nervous system. Poisoning;

Some people say that long-term drinking of water from an electric kettle can cause kidney stones.

So, is the above statement accurate? Will drinking water boiled by an electric kettle for a long time make people sick, poisoned, and carcinogenic?

First, drinking water boiled by an electric kettle for a long time will cause the body to be poisoned and cause cancer? 2 suggestions to listen to

People often smell the smell of disinfectant water in tap water, this is because the tap water has added chemicals such as chlorine, After a series of complex treatment procedures in the water plant, it flows into thousands of households through the tap water pipeline, so people often think that drinking such water will cause poisoning.

So why add chlorine to tap water?

This is because in order to completely kill the microorganisms in the tap water, the water plant adds an appropriate amount of chlorine to the tap water, and then sends the treated tap water to thousands of households. households, which explains why many people smell disinfectant water in tap water.

Of course, the chlorine added in tap water is completely within the acceptable range of the human body, which is more in line with the relevant regulations of the state on tap water, and will not have toxic effects on the human body. So people don’t need to worry too much. But it is not recommended that you drink tap water directly, which is not good for your health.

Nowadays, the electric kettle has replaced the water dispenser as the most commonly used water boiling tool. However, many people find that after using the electric kettle for a period of time, they will find a layer of white scale on the inside of the kettle.

This creates an illusion for many people that limescale can make water quality worse, and long-term drinking can increase the risk of kidney stones.

Studies show that the main components of scale are non-toxic magnesium carbonate and calcium carbonate. These two substances are precipitated from the water under the action of high temperature, and they are both insoluble in water, and over time, scales are formed on the wall of the pot. In general, hard water (water with a high content of calcium and magnesium ions) easily leads to the formation of scale.

Therefore, the scale formed in the electric kettle does not adversely affect human health.

So, are the metal components in electric kettles harmful to human health?

Currently electric kettles in the market are made of stainless steel or high manganese steel, and many people worry about the long-term use of electric heaters made of high manganese steel Kettles can lead to excessive levels of manganese in the body, which can lead to poisoning and even cancer.

However, studies have shown that using this type of kettle to boil water will hardly precipitate manganese, so there is no so-called poisoning and carcinogenic claims. , you can drink it with confidence.

In addition, manganese has certain benefits for the human body. It plays an important role in the metabolism, development and other life activities of the human body. Human health is very beneficial.

Although several rumors about electric kettles mentioned above have been proven to be rumors, be careful when choosing an electric kettle,Here are a few suggestions on buying an electric kettle.

Try to choose 304 or 306 stainless steel and other foods An electric kettle made of high-grade materials. This is because the electric kettle will be tested by GB9684 before it leaves the factory. After passing the test, the “GB9684” logo will be printed on the qualified electric kettle.

Regular cleaning of limescale is also essential. As mentioned above, although the scale does not have toxic effects on the human body, the large amount of calcium contained in the scale will cause health problems such as muscle weakness once the human body consumes too much.

This is because excessive intake of calcium by the human body will cause the blood calcium concentration in the human body to be too high, reduce the excitability of muscles and nerves, and affect the function of muscles , resulting in muscle weakness.

Second, beware of drinking water safety! Drinking the wrong water may increase the risk of colorectal cancer!

As mentioned above, the safety of drinking water is very important to human health. Latest research suggests that high levels of nitrates in drinking water may increase the risk of colorectal cancer.

This is a New Zealand-wide study of the relationship between nitrate levels in drinking water and cancer risk, based on existing According to the data, researchers estimate that at least 800,000 New Zealanders drink water with excessive nitrate levels.

In these populations, the risk of rectal cancer was increased by 16%, the risk of colon cancer was increased by 27%, and the risk of colorectal cancer was increased by 39% %. Therefore, this is also enough to show that drinking water with excessive nitrate content for a long time will cause great harm to human health and lead to a great increase in the incidence of certain diseases.

In order to accurately assess the possible harm to the human body caused by long-term drinking of water with excessive nitrate content, out of a rigorous point of view, the study The staff also conducted a comparative analysis of nitrate and other factors that may lead to colon and rectal cancer such as alcohol consumption, smoking, obesity, etc., and listed the attributable fraction (PAF) of the corresponding population .

It is not difficult to see from the above graph that although the PAF value of the nitrate group (3.3%) was lower than that of the obese and alcohol-drinking PAF, it still proved that drinking High levels of nitrates in water can increase the risk of colorectal cancer. It seems that excessive nitrate levels in drinking water can indeed increase the risk of cancer, so people must be vigilant.

Meanwhile, the wrong way to drink water can be bad for your health.

Drinking too much water can lead to water intoxication. Studies have shown that when the human body cannot metabolize excess water, excess water will remain in the body, reducing the osmotic pressure of the blood, and people will suffer from water intoxication. In severe cases, the nerve tissue will be damaged. damage.

This is even worse for people with liver and kidney disease. Therefore, drinking water must be in moderation. Studies have shown that light laborers can drink up to 1700mL per day; people with high uric acid levels and gout patients can drink up to 2L of water per day.

Don’t wait until you feel thirsty to drink water. Most people often wait until they feel thirsty to drink water, which is not the right way to drink water, but should drink a few sips of water every once in a while regardless of whether you feel thirsty or not.

Third, after the experiment, the two scientists said that they would no longer use this plastic bottle to drink water. ..

Nowadays, the dazzling array of beverages in plastic bottles has attracted people’s attention. Especially for people who like drinks, it is likely to pick a plastic bottle to reuse. Is the long-term use of this plastic bottle harmful to human health?

In a study published in February 2022, two chemists from Denmark detected hundreds of different chemicals in reusable plastic bottles, some of which are harmful to human health , but toxicity is unclear.

To determine which chemicals the plastic bottle would release into the water, researchers selected new bottles, used Bottles that have been washed, bottles that have been washed, and left to stand for 24 hours after containing drinking water. They then tested the bottles.

Test results Eye-popping: Over 400 plastic-related compounds were detected, including some never before seen.At the same time, they also found that most of these compounds are plasticizers, antioxidants, photoinitiators, etc. .Obviously, these substances are very harmful to human health.

After the study, the two chemists said they would no longer use the plastic drinking cups and replace them with glass or a high-quality stainless steel thermos.It seems that plastic drinking glasses do contain a lot of substances that are harmful to human health, so people should reduce the use of plastic drinking glasses as much as possible.

Extended reading: Is it safe to drink hot water from disposable paper cups?

Over the years , Disposable paper cups are widely favored by people as a common cup.You can use it to hold a cup of coffee on the way to work in the morning, and you can use it to pick up a cup of hot water when you are entertaining guests in the office. Because the disposable paper cup is small in size, easy to carry and cheap, it is deeply loved by everyone.

However, is the use of such cups harmful to human health? I’ll reveal it to you below.

In December 2020, a study from the Indian Institute of Technology found that disposable paper cups will degrade to a certain extent within 15 minutes of holding high-temperature liquids, releasing liquid microplastic particles, harmful ions and heavy metals are released.

The investigators conducted two trials. In the first group of tests, the water at 85-90°C was poured into the disposable paper cup and let stand for 15 minutes; in the second group of tests, the disposable paper cup was first soaked in water at 30-40°C, and then the The hydrophobic membrane was separated and the membrane was placed in hot water at 85-90°C for 15 minutes.

After testing the two sets of disposable paper cups, researchers detected fluoride, chloride, lead, chromium and other substances that are harmful to human health in the water. substance.

Obviously, long-term use of disposable paper cups to hold high-temperature liquids will be very harmful to human health. Therefore, people should minimize the use of disposable paper cups.
