ELECTRICITY IN THE HUMAN BODY

The human body is electrical, and the body generates its own electricity through chemical signals in the cells. The body's electrical signals control and enable everything we do, including synapses, signals and heart-beats. For example, action potentials within neurons help cells communicate with each other. Movement of these ions across the cell membrane generates an electrical pulse known as an action potential. Our nervous system uses these action potentials to send signals around our body. Without electrical impulses in our bodies we couldn't read this page, stand up straight, react to pain or even have a heartbeat. The average human body produces about 100 watts of power at rest, which is enough to power a light bulb.
