First of all, we should all know that there have been many reports that if the kettle body is made of non-304 food-grade materials, long-term use will cause certain harm to the human body, which also makes more and more people have a series of concerns about the use of the kettle. However, some water bottles are food grade 304 stainless steel, while others are replaced with high manganese steel. Although manganese is an indispensable trace element for human body, hot water bottles made of this material will precipitate heavy metals for a long time, because manganese is easy to precipitate at high temperature for a long time, and these accumulated heavy metals are harmful to human body and damage people's memory.
Boil water with an electric kettle. The water boiled in the electric kettle is drinkable, but it should be noted that the electric kettle is made of different materials and the price is different. Some electric kettles cost several hundred yuan, while others only cost tens of yuan. Potential health hazards can be seen from the price. Drinking water from cheap electric kettles for a long time will definitely have more or less influence on people. Ordinary and cheap electric kettle is made of high manganese steel, which belongs to wear-resistant steel. Usually used in heavy industry, the appearance is obvious. Long-term exposure to non-food grade high manganese steel, if the heavy metal manganese contained in it dissolves and precipitates, will cause great harm to the human body, directly damage the human nervous system and lead to mental depression, which is a common symptom of heavy metal poisoning.
Therefore, to sum up, the hot water kettle can't be used for a long time, which will affect our health more or less.
