Neurotransmitters are the brain's chemical messengers that play a crucial role in regulating our mood and emotions, influencing everything from happiness to anxiety. In art therapy, engaging in creative activities can significantly boost levels of neurotransmitters like serotonin and dopamine, leading to improved emotional well-being. When clients express themselves through art, they not only find a powerful outlet for their feelings but also activate areas of the brain associated with pleasure and reward, creating a positive feedback loop that fosters healing and personal growth.
