What are bioelectrical signals?

Bioelectrical signals are tiny electric messages that help your body talk to itself.

Imagine you're playing a game of telephone with your friends, except instead of whispering in ears, your body uses tiny electrical messages to send instructions all over the place. These messages let your brain tell your hands to move, or your heart to beat, or even let your skin feel warm when you touch something cozy.

Think of your nerves like wires and your cells like batteries. When your body needs to send a message, maybe to make you laugh or run away from a scary monster, the battery (the cell) sends electricity through the wire (the nerve), and the message gets delivered just like that!

Sometimes, these messages are really fast, like when you blink an eye in response to something bright. Other times, they're slower, like when your body is healing a scraped knee.

It's like having a whole bunch of little helpers inside you sending messages all day long, without even needing to whisper!
