Emotion involves both physiological and cognitive processes. Physiological changes in the face, brain and body accompany emotions. The brain, particularly structures like the amygdala and prefrontal cortex, play a key role in emotional experiences. Cultural influences also shape how emotions are experienced and expressed. Theories like the James-Lange theory and cognitive labeling theory view emotions as arising from the interpretation of physiological arousal. Effectively managing emotions and the stress they can cause is important for health and well-being.
