In our last post, we introduced the neurodivergent nervous system as a “canary in the coal mine”—a sensitive system that gives us an early warning about the stressors of modern life. Now, let’s explore one of its most powerful lessons: a simple map for understanding your own mental state and staying regulated.

This map is called the “Window of Tolerance.” It’s a powerful model for understanding the optimal zone of nervous system arousal where we function at our best.

Think of it like this:

• Inside the Window (The Eunoia Zone): This is the optimal state where “beautiful thinking” happens. You are calm, present, connected, and able to learn, think rationally, and handle life’s challenges with clarity.
• Hyperarousal (The Red Zone): When you’re pushed above the window, your nervous system goes into “fight or flight.” This feels like anxiety, chaos, anger, or being overwhelmed.
• Hypoarousal (The Grey Zone): When you’re pushed below the window, your system can go into “freeze” or “shutdown.” This feels like numbness, disconnection, emptiness, or brain fog.

While everyone has a Window of Tolerance, a more sensitive, neurodivergent nervous system can provide a clearer, more amplified signal when it moves outside this optimal zone. The lesson for everyone is to cultivate this same sensitivity and self-awareness. Instead of waiting for a full-blown panic attack or complete burnout to realize we’re dysregulated, we can learn to spot the subtle, early cues that we are drifting outside our window. The neurodivergent experience teaches us the critical importance of this nuanced self-monitoring.

To apply this lesson, don’t wait until you’re 100% overwhelmed. This week, practice the “2% Audit.” Try to notice the very first 2% shift in your state. What does the beginning of anxiety feel like in your body—a slight tightness in your chest? A change in your breathing? What does the beginning of a shutdown feel like—the first impulse to endlessly scroll your phone to numb out? Noticing the first signal gives you the power to respond before you react.

Building the self-awareness and discipline to manage your internal state is a daily practice. Our 30-day workbook, Forge Your Freedom, is designed to help you build the powerful routines that allow you to stay within your Window of Tolerance more often.
