Why Do We Get ‘Blisters’ from Hot Surfaces?

We get blisters from hot surfaces because our skin gets burned and starts to bubble up like a hot soup in a pot.

When you touch something really hot, like a stove or a grill, the heat goes into your skin, just like water goes into a pot. If it's hot enough and you stay on it for too long, the heat cooks the skin underneath, kind of like how heat makes soup bubble up.

What Makes Blisters Pop?

Your skin has layers, like an onion. The bottom layer gets cooked by the heat, while the top stays a bit cooler. This creates a bubble, like when you put a lid on a pot and steam pushes it up. That bubble is your blister!

Sometimes blisters pop because they get too full of liquid, just like a balloon that bursts if it's stretched too far.

Why Do They Hurt?

Blisters hurt because the skin underneath is raw and sensitive, like a sore tooth. When you touch something hot, it’s like getting a tiny burny hug from the heat!
