The "Zones of Regulation" is a framework and curriculum designed to help individuals, especially children and young adults, understand and manage their emotions and states of alertness. It uses a color-coded system with four zones (Blue, Green, Yellow, and Red) to categorize different emotional and physiological states. The Zones of Regulation also offers digital products, including apps and a digital curriculum, to supplement the original book. These resources provide interactive tools and activities to help individuals learn and practice self-regulation strategies.
