Emotional contagion is the phenomenon where one person's emotions can influence the feelings of others around them. This can happen through nonverbal cues, such as facial expressions, tone of voice, and body language. For example, if someone is smiling and laughing, it can make others feel happier and more relaxed. This process occurs naturally in social interactions and can happen in various settings, including workplaces, friend groups, and families. Emotional contagion plays a significant role in group dynamics, as shared emotions can strengthen bonds and create a sense of community among individuals.
