How do warm clothes keep us warm? Shouldn’t heat be expelled outside nevertheless?
In: 1
Imagine a bucket with a massive hole in the bottom. It loses water super fast, right? Now imagine we made that hole smaller. You lose water, but not as fast. If we had a hose pumping water into the bucket, we could even make the water level *rise* if we made the hole small enough.
This is how clothes work. Your body is constantly producing heat. The idea of clothes is to limit how quickly that heat escapes the area around your body. If you can limit that rate to slower than your body produces heat, you can stay warm.
