Reply to comment by epsilona01 in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

Anecdotally it does feel like the sweating that happens when one is suddenly scared/anxious seems different, like it suddenly starts seeping out of you without any of the physical work it 'normally' requires to produce.
