What is heartbeat?

A heartbeat is like a drum that keeps your body moving and working.

Imagine you have a toy robot friend who needs to walk around all day. Every time it takes a step, it uses a little ping sound from inside, that’s like a heartbeat! Your heart does something similar: it sends blood all over your body so you can run, play, think, and grow.

Your heart is a strong muscle in your chest. It beats because it has special parts called chambers, which push blood out to your body and bring fresh blood back in.

Every time your heart beats, you feel a thump, like when you press on a balloon and let the air out, then squeeze it again.

If your heartbeat was too slow or too fast, your robot friend might trip or get tired quickly. The same happens to you! That’s why keeping your heartbeat steady is important, it helps you stay strong and happy all day long.
