Electricity has become a necessity of our daily life. Modern people can't stand a day without electricity. Now we have many things that need to be supported by electricity, such as office computers, rice cookers and so on. People feel the benefits of electricity as soon as they mention it. At the same time, they are very afraid of the danger it brings to human beings.
When it comes to electricity, we think of the terrible appearance of electric shock. Many people die of electric shock every year. When the current passes through the human body, the degree of injury to the human body is closely related to the magnitude of the current. When the current passes through the human body, the human body will have a series of feelings such as numbness and pain. In serious cases, it will cause the body to shake and spasm, and then the heart will stop beating until death. The greater the current, the more intense the response to the human body, the more obvious the physiological response and the stronger the feeling. The injury degree of electric current to human body is closely related to human condition when it passes through human body. Each person has different physique and sensitivity to electric current, which leads to different people's response and danger degree will not be completely the same when they are shocked by the same electric current.
Generally speaking, women are more sensitive to current than men, children are less likely to get rid of current, and the risk of electric shock is much higher than that of adults. People with heart disease suffer much more from electric shock than healthy people.
You may not know that electric current also has a good effect on the human body. A certain amount of electric current can expand the capillaries in the body and speed up the blood circulation. It can not only reduce the pressure of the heart, but also enhance the cardiovascular function. In some medical and health care materials, it can be learned that it is beneficial for human body to pass a small amount of electric current, which can be disinfected and sterilized to a certain extent. For example, massage centers with electrotherapy now use this principle to serve customers. This kind of method can't be tried by yourself. Don't take risks without the help of experts. Electric current has advantages and disadvantages for our human body. We should not generalize. We should start from multiple angles for one thing. In life, we still need to avoid electric shock. After all, its harm is more than good. We are all non professionals, unable to control the amount of electric current that is good for human body.
