11. Fear Can Be Contagious
Did you know that fear can spread from one person to another, much like a cold or flu? In 2008, scientists experimented by comparing the sweat of people trying skydiving for the first time to those running on a treadmill. Volunteers were asked to smell both types of sweat. Interestingly, the treadmill sweat didn’t cause any major reaction in their brains.
However, the skydivers’ sweat triggered brain areas associated with fear. This is because first-time skydivers experience intense fear, and their sweat carries those emotional signals. A 2012 study confirmed this phenomenon, showing that fear can be “transferred” through scent.
