We know that drinking more boiled water is good for human body, which can not only promote the timely discharge of metabolic wastes in human body, but also replenish water for human body, prevent premature aging of skin and moisturize skin. It is best to drink seven or eight glasses of water a day, which is helpful to all aspects of the body. However, the quality of boiled water should also be guaranteed. Like ordinary tap water, there are many impurities. After boiling, these impurities will adhere to the inner surface of the kettle, which will form thick scale after a long time. Many people think it is normal to have scale in the kettle, so there is no need to make a fuss, so they don't take it seriously at all, but continue to boil water in a kettle full of scale, which is not recommended.
In fact, the scale in the kettle needs to be removed in time, because it is harmful to human body. The main component of scale is calcium ion. Boiling the kettle for a long time will accumulate a lot of scale on the inner wall of the kettle. After the scale accumulates more, it will be brought into the water when it is boiled, so it will be drunk by people. If the scale is not cleaned for a long time, the human body will drink more and more boiling water with scale, which will cause harm to the human body. The most typical one is lithiasis, and there have been many lithiasis in recent years. It's not a big problem, but it's painful. Secondly, the concentration of calcium ions ingested by human body is too high, which will lead to muscle weakness.
In fact, removing the scale from the kettle is very simple. For example, you can add baking soda to water, then wait for the water to boil and soak for a while, and the scale will dissolve. Then pour out the water with scale and wash the kettle, or you can add tea leaves to soak it. Either way, the scale must be removed.
