In ordinary households, most of the drinking water sources are high-quality and cheap tap water, and some people may drink raw water directly. Now with the improvement of material life, people have also pursued the safety of water.
In the past few days, people have begun to suspect that water boiled from tap water, such as overnight water and thousand boiling water, is related to it. But the facts have proved that under a large number of studies, it has not been found that, no matter how many times the tap water is boiled, it is safe to eat as long as it is boiled.
Someone asked again, if people drink water from an electric kettle every day, is there any harm to the human body? Tell everyone with experiments.
For ordinary tap water, which contains residual chlorine, this substance can inhibit bacteria, but because of its unstable nature, it has an obvious pungent smell. Outside sunlight, or after people are heated, it is easy to produce other chlorine-containing compounds that affect health.
Through experiments, we found that in the detection of our daily drinking water, the residual chlorine content of tap water is less than 2 mg per liter of water, so we can drink with confidence. But for safety reasons, if people feel pungent after smelling it with their nose while drinking water, there may be chlorine, so it is best not to drink it.
From this we can know that tap water is safe in most cases. As mentioned above, in addition to tap water, there is also an electric kettle for heating water. Will it cause problems?
The common electric kettles on the market are all made of stainless steel and are fixed in accordance with national standards. Through daily cleaning, they will not produce substances harmful to health. However, because some people did not pay attention when buying, they chose low-priced electric kettles. Electric kettles like
are prone to food safety problems. Therefore, there are rumors that non-compliant electric kettles contain manganese. After high-temperature heating, manganese is precipitated, and people are prone to manganese poisoning, dizziness, fatigue, and memory loss. Nausea and vomiting, poor emotional state, etc., should be suspected of heavy metal poisoning and go to the hospital for treatment in time.
Although people are prone to poisoning after a large amount of manganese is ingested, there is no need to worry too much. According to the characteristics of the digestive system, the absorption of manganese is as high as 5%, and manganese poisoning is unlikely to occur.
Therefore, if you usually like to drink tap water boiled, you should pay attention to two aspects. One aspect is to buy an electric kettle with a safety mark from a regular manufacturer. On the other hand, when drinking water, pay attention to its temperature, do not exceed the temperature that the esophagus can withstand, and drink water above 65 degrees Celsius.
pointed out in the International Cancer Agency of the World Health Organization that beverages and food with a temperature above 65 degrees Celsius can damage the esophageal mucosa and easily induce esophageal cancer.
