<human>:  How does electricity affect our bodies?
<bot>: Electricity can have both positive and negative effects on our bodies. It can be used therapeutically to reduce inflammation, improve healing, and promote muscle relaxation. But it can also cause burns, shocks, and other physical harm if used improperly or in excess. Generally, the greatest danger from electricity is from electric shocks if an individual touches a live wire or comes into contact with a strong electrical current. Some people are also affected by electromagnetic fields produced by electrical equipment or power transmission lines, which can cause headaches, fatigue, and skin rashes.
