Drinking more hot water has always been a common phrase that Chinese hangs on the lips. Water can promote metabolism, beauty and beauty, but also a must for the human body. In winter, a mouthful of hot water is used to warm the stomach and the body.
Among them, the electric kettle boils water quickly and is easy to use, so it has become a must-have appliance for many families, and the electric kettle is indispensable for people who are accustomed to drinking tea and coffee.
However, I recently heard that drinking water boiled from electric kettles for a long time is harmful to our health! So, is this true?
What are the dangers of boiling water in electric kettles?
1. Heavy metals
The main material of the electric kettle is stainless steel, but there are many kinds of stainless steel materials, if the use of manganese elements is much higher than the 201, 202 stainless steel materials of 304 stainless steel, then when boiling water, manganese and other heavy metal elements may be precipitated on the inner wall, although usually we may also ingest manganese elements in our diet, but long-term drinking of manganese exceeding the standard of water, it must be harmful to the body, such as dizziness and weakness.
2. Scale
Secondly, long-term use of electric kettle to boil water, the use of long time will appear scale, although the composition of scale is calcium magnesium ions, a small amount of scale will not affect the health of the human body, but also if it exceeds the standard, it will also have a certain impact on human health.
Secondly, the thermal conductivity of scale is not good, and when used, it may affect the boiling speed of the kettle, increase the power consumption, and affect the service life.
It can be seen that improper use is a certain threat to health, so we should pay attention to these 3 aspects when using electric kettles to boil water.
1. Select a qualified product
(1) Look at the logo: Before purchasing, pay attention to check whether the pot of the electric kettle has a 304 stainless steel logo, 304 stainless steel belongs to the food grade stainless steel, harmless to the human body, and then you can also check whether it has the "GB9684" logo, which is also a qualified electric kettle.
(2) Choose a big brand: if you use an unqualified fake electric kettle,
In addition to the possible adverse health, there may also be hidden dangers in the safety of electricity, so it is best to choose large brand products to ensure quality.
2. Do not bring to a boil repeatedly
In the winter, the boiling hot water will soon become cold, so many people will choose to boil the water again in order to avoid waste.
However, repeated burning meetings becomes "thousand boiling water", which is easy to produce nitrites that are harmful to our health, so it is recommended to drink as much as you want to burn, or put the boiled water into the thermos pot to keep warm.
3. Clean regularly
Clean the scale regularly, but pay attention to wiping with a soft rag, do not hard objects, avoid destroying the protective layer, so that harmful substances dissolve.
Summary: Drinking water is a trivial matter in our lives, but if you don't pay attention, it may pose a threat to the body, so we must pay attention to the safety of drinking water.
