Human Body
When people experience fear, they release chemicals like adrenaline that alter the composition of their sweat. Studies have found that others can detect these changes and subconsciously perceive them as signals of fear. This sense isn't explicit like smelling roses; it's more subtle, affecting mood and anxiety levels of those nearby. Disgust and happiness can also be detected through similar olfactory cues.
