On being around people who are AFRAID or STRESSED V.S. People who are HAPPY, CALM, or NEUTRAL. According to my Biology textbook: ..Research suggests that people may also be able to detect chemical indicators of fear or stress. For example, in 2009 Lilianne Mujica-Parodi and her colleagues performed an experiment in which they collected sweat samples from 144 people. Half the people were sampled during a first-time skydive with a 1-minute freefall, the other half (the controls) were sampled during a bout of exercise. Test subjects then smelled one of the two types of samples while undergoing brain imaging. A brain region called the amygdala, which is associated with strong emotions such as fear and rage, was active in subjects who smelled the stress sweat from the skydivers, but not in the subjects who smelled the exercise sweat. A chemical present in the sweat of emotionally stressed people apparently triggered a similar emotion, or at least a similar brain response, in people exposed to the chemical.
