Pleasant.
None (of the sniffing students) perceived a difference between the two types of sweat, but the pre-exam sweat had a different effect on brain activity, lighting up areas that process social and emotional signals, as well as several areas thought to be involved in empathy...
A previous experiment found that sweat from skydivers activated anxiety circuits in sniffers' brains.
