Physiology of Emotion

The physiology of emotion involves how our brain and body respond to feelings. When we experience an emotion, the brain processes it and signals the nervous system, releasing chemicals like adrenaline or cortisol. These chemicals trigger physical responses—such as a racing heart, faster breathing, or sweating—preparing us to act (like fighting or fleeing). Different brain areas, like the amygdala, evaluate emotional significance and help coordinate these responses. Overall, emotions are a complex interplay between brain signals and bodily reactions that help us interpret and respond to our environment effectively.
