your body's panic AC, dripping proof that staying cool is hard work

means The salty liquid your skin releases to cool you down when you're hot, working hard, or nervous.

from From Old English 'swat,' meaning sweat or perspiration, with deep Germanic roots — a cousin of Dutch 'zweet' and German 'Schweiß.' Trace it back further and it likely springs from the same ancient Proto-Indo-European source as Latin 'sudor' (sweat — the root behind 'sudorific') and Sanskrit 'sveda.' Humans have been dripping, and naming the drip, for a very long time.
