When you're exposed to high enough heat, something called dynorphin is released.

当围温度足够高时，大脑会分泌一种叫强啡物质。

That's not the result we're going for, but when dynorphin is released, more of the receptors that endorphins bind to are created and it sensitizes them to endorphin.

这显不是我们想要，当强啡产生之时，会生成更多内啡受，它们对内啡十分敏感。
