The first reason is that when we are accidentally excited by the current, when the current circulates from the inside of our human body, the electrical balance between nerves and cells in our human body will be disrupted instantly due to the invasion of external current. Especially for this part of the nerve, the external invading current will make the conduction between the nerves abnormal. Therefore, the stimulation received by the skin can not be transmitted to our central nervous system normally, and at this time we will feel the symptoms of numbness appear on the skin surface.
The second reason is related to the structure of the human body, which can be regarded as a very large resistance. Moreover, the human body is conductive, so when we accidentally touch the power supply, when the current flows from our hands to our whole body, the resistance inside the human body will become larger. At this time, when the current passes through our body again, we will feel the symptoms of numbness. Another reason is that the nerves of the body are very sensitive to external interference, and the interference form of current will make the nerves more sensitive to him, so they will feel numb.
Of course, electricity is a very dangerous thing for people. We must never touch the power supply, let alone touch the power supply when there is water in our hands. Once it is hit by the power supply, it is very dangerous, which will make us feel uncomfortable, and it is very likely to lead to the loss of our lives.
