Dopamine does not “eliminate” a specific emotion. It is a neurotransmitter mainly involved in motivation, reward prediction, learning, and goal-directed behavior. Emotions emerge from multiple systems—dopamine, serotonin, norepinephrine, GABA, glutamate, and stress hormones—working together. However, chronic overstimulation of dopamine pathways can contribute to emotional flattening, impatience, and reduced enjoyment of low-intensity activities in some people. This is better explained by reward tolerance and disrupted attention–reward balance rather than a single chemical “removing” an emotion. A better framework is systems thinking: sleep, stress load, screen exposure, nutrition, and mental health factors all shape emotional experience.
