What can occur when voltage pushes electrons through the human body?

When voltage pushes electrons through the human body, it can lead to serious consequences, including injury or even death. This phenomenon occurs because electrical currents can interfere with the body's normal electrical signals, particularly those that control the heart. For instance, a current can disrupt the rhythm of the heart, potentially causing arrhythmias or stopping the heart altogether. The severity of the effects depends on several factors, such as the voltage level, the path the current takes through the body, and the duration of exposure.

Unlike any suggestion that electrical currents might have positive effects on the heart or blood circulation, the reality is that electrical shock poses a significant risk and can result in severe physical harm. Understanding these risks is crucial for electrical safety and highlights the importance of using caution around electrical sources.
