This free five-part mini course explains the story of CIRS in the simplest possible way — without medical jargon, confusing abbreviations, or technical lab language.
Learn why the body can become stuck in emergency mode, why symptoms may appear throughout the entire body, how an indoor environment can become part of the story, and why many people spend years searching for answers.
Free access. No medical background required.
You have symptoms in several parts of the body, but no one has connected them.
You experience brain fog, fatigue, poor sleep, pain, sensitivity, or unusual changes in how your body feels.
You feel worse in a particular home, workplace, classroom, hotel, or other building.
You sometimes feel better after being away from a certain environment.
You have been told that common tests look normal even though you still feel unwell.
You have seen several professionals, but each one seems to focus on only one part of the problem.
You are trying to understand whether the environment could be connected to how you feel.
These experiences can occur for many reasons. This course is educational and does not diagnose CIRS or determine whether a building is causing symptoms.
Your body is designed to protect you.
When it believes danger is present, it changes how it uses energy, how clearly you think, how deeply you sleep, and how strongly you respond to the world around you.
Normally, that emergency response turns off when the danger passes.
CIRS can be understood as a condition in which the body has trouble returning to normal and continues acting as though the emergency is still happening.
The course uses the body-as-a-city metaphor to make that story clear.
A simple visual journey through the story of CIRS.
Understand why the brain, sleep, energy, digestion, immune response, mood, and other body systems are connected.
Learn why the body creates an alarm response and why symptoms may actually begin as an attempt to protect you.
Learn the simplest foundational explanation of what CIRS is and why the body may remain stuck in emergency mode.
Understand how water-damaged buildings and other environmental exposures may become part of the body's alarm response.
Learn why patients are often sent in many different directions while no one connects the medical and environmental pieces.
The learning assistant will help you connect each lesson to your own reason for enrolling. It may ask what symptoms or patterns brought you here, whether your experience seems connected to a certain building, and whether you have struggled to find one explanation for many different symptoms.
The learning assistant is educational only. It does not diagnose, interpret personal medical results, recommend treatment, or evaluate a building.
