What are internal sensors?

Internal sensors are like special helpers inside your body that tell you what’s going on without you even noticing.

Imagine you're eating a big bowl of soup. You don’t need to look at it, you can tell if it's hot or cold because of the sensors in your tongue, which send messages to your brain saying, “This is warm!” or “This is burning!”

Your body has many internal sensors that work like little helpers. For example:

• The heart has sensors that tell it how fast to beat.
• Your stomach has sensors that let you know when you're full.
• Even your bones have sensors that help you know if you're growing or getting taller.

These sensors are like tiny reporters, they send messages to the brain, telling it what’s happening inside. And just like how you can feel a soft pillow under your head, your body feels these changes thanks to its internal sensors, working hard all day long!
