What is Thermal feedback?

Thermal feedback is when something gets hotter or cooler because of its own temperature changes.

Imagine you're wearing a thick winter coat on a cold day. Your body warms up, and that warmth makes the coat feel cozy, but if you keep wearing it for too long, your body might get too warm inside the coat. That extra heat can make you sweat, and then your coat feels less cozy, maybe even uncomfortable. This is like thermal feedback: your body’s temperature affects how you feel, and that feeling changes how much heat your body keeps or loses.

Think of a thermometer. When the temperature goes up, the liquid inside expands and moves up the tube, showing a higher number. If there's no one to read it, the thermometer just keeps showing the same temperature until something changes again. That’s like how thermal feedback can stabilize or change things based on what happens next.

Or picture a campfire. The fire gets hotter, and that heat warms up the air around it, which makes more air rise, feeding the fire even more. It's like a loop: the fire heats the air, the air helps the fire grow, and the whole thing keeps getting warmer, thermal feedback in action!
