Areas of the brain can be reshaped and reorganized through activities that include touch and movement—the foundation of creative expression. Just as trauma is experienced—through nonverbal sensation—it can be released. Research found that the simple act of art-making, regardless of skill level, reduces cortisol (or stress levels) in the brain. By making art, children learn about themselves and widen their perspective, creating empathy and deeper engagement.
