Understanding Your Nervous System

A Sensory Pyramid Workbook - an OT-informed introduction to the body-based foundations of regulation.

When someone struggles with focus, overwhelm, or emotional responses, the conversation usually starts at the top - with thoughts, behaviour, and coping strategies.

But regulation doesn't begin at the top. It begins in the body.

This workbook introduces a bottom-up approach to understanding the nervous system - exploring how sensory and body-based experiences shape the way we pay attention, respond to the world, and regulate our emotions in everyday life.

Created by Rachel and Caitlin, Occupational Therapists and founders of Sensory Sanctuary Co., this resource offers a grounded, accessible starting point for anyone curious about why their nervous system works the way it does.

What this workbook covers:

• An introduction to the sensory pyramid of learning, adapted from Williams and Shellenberger and grounded in Ayres' sensory integration theory
• The role of sensory systems in supporting regulation
• How body-based experiences may influence attention, behaviour, and emotional responses in daily life
• A guided self-reflection worksheet to help you begin connecting this to your own experience
• General strategies that may support regulation in everyday environments
• Prompts to support awareness and practical application

This resource may be helpful for:

• Individuals wanting to better understand their own nervous system
• Adults experiencing overwhelm, difficulty focusing, or sensory sensitivities
• Parents or caregivers seeking general, accessible information
• Professionals looking for a supportive educational tool to use alongside their practice

This is a starting point, not a solution. But sometimes understanding where to begin is exactly what's needed.
