Current is not good for human body, but not good. Current can be divided into direct current and alternating current. Alternating current can be divided into power frequency electricity and high frequency electricity. These currents are harmful to human body, but the degree of harm is different. The ability of human body to withstand direct current and high frequency electricity is stronger than that of power frequency electricity. Therefore, power frequency electricity is the most harmful to human body.

When the human body directly contacts the power supply or high-voltage electricity conducts current through air or other conductive media, it will cause tissue damage and dysfunction, and in severe cases, heartbeat and respiratory arrest will occur.

Harm of electric current: When electric current passes through important internal organs of human body, the consequences will be very serious. For example, through the head, it will destroy the brain nerve and cause death. Through the spinal cord, it will destroy the central nervous system and paralyze people. Passing through the lungs can make it difficult to breathe. Passing through the heart will cause the heart to vibrate or stop beating and die. Among these injuries, the heart injury is the most serious.

According to accident statistics, the most dangerous route through human body is from hand to foot, followed by hand to foot, and the least dangerous route is from foot to foot, which may lead to secondary accidents.
