What is touch?

Touch is how we know when something is near or far by using our skin, just like feeling a hug from a friend.

How touch works

When you press your hand against a wall, tiny helpers inside your skin called sensors notice the pressure and send messages to your brain. It's like having little detectives on your skin that shout, "Hey! Something is touching me!" Your brain hears them and knows it’s time to stop or move.

What touch feels like

Imagine you're holding a soft pillow and then switch to a rough towel, that's touch helping you tell the difference. If you're playing with blocks, your fingers can feel if they’re smooth or bumpy, just like how you know when it’s time for snack because your hand feels full.

Touch is like having a map on your skin that tells you what's going on around you, and it helps you play, learn, and even know when to let go of something you're holding. Touch is how we know when something is near or far by using our skin, just like feeling a hug from a friend.
