Microwave ovens are cooking tools that many families have, because they are heated quickly and conveniently, and they are loved by people. However, the heating principle of the microwave oven is different from that of the conventional traditional cooking tools. If you do not pay attention to the use, it is easy to cause some problems, and even threaten the health of the body. Microwave ovens may be of particular concern in addition to their use, such as the so-called microwave oven radiation problem.
Let us first talk about the principle of microwave ovens. The reason why microwave ovens can heat food is to make high-frequency vibration of water molecules in food through "microwave", and high-frequency vibration will generate heat, which can be used for food. Heat up.
Knowing the principle of microwave heating, we should pay special attention when using microwave oven to heat some special foods. For example, you can't heat a whole egg in a microwave oven. This is because microwaves can cause "bumping" of the liquid inside the egg. Once the inside of the egg is overheated and the pressure is high, it will explode when the pressure is released. In addition, the cleaner the container, the cleaner the water, the more prone to a violent boiling phenomenon, so do not use a microwave to boil water or boil milk and soup. If you must use a microwave oven to heat these liquid foods, be sure to control the time.
Let me talk about the microwave microwave oven will not cause harm to the human body. Many people say that microwave ovens have a lot of radiation. This is because people don't understand "radiation." The radiation we have heard in life is often from the "nuclear radiation" in news or accidents, which is not the same as the radiation of microwave ovens we are talking about today. In fact, radiation is everywhere around us. Sunlight is a higher-energy electromagnetic wave than microwave. Are you afraid of the sun? You are not afraid of the sun, why should you be afraid of microwave ovens?
The safety of microwaves is the same as that of sunlight. Whether it is harmful to people depends mainly on the strength of energy. The mild sunlight will make people feel comfortable, while the hot sun will hurt people. The same is true for microwaves. Since it can heat food, it can naturally heat the human body. The question is, how much energy does the microwave reach the human body?
For daily use, there is a maximum of 1 milliwatt of energy from a 5cm microwave oven. Therefore, as long as your microwave oven is not broken and it is a qualified product, it will not cause any harm to people.
