CIRS: Symptoms, Causes & Nervous System Dysregulation

Chronic Inflammatory Response Syndrome (CIRS) describes a pattern in which the body develops a persistent inflammatory response following exposure to environmental biotoxins, most commonly associated with water-damaged buildings. These environments can release mold fragments, microbial byproducts, and other contaminants that may act as ongoing stressors to the immune and nervous systems. Individuals may experience symptoms such as fatigue, cognitive fog, headaches, dizziness, respiratory irritation, muscle or joint discomfort, and difficulty tolerating environmental exposures.

While these symptoms can be distressing, they do not necessarily indicate permanent damage. Rather, they often reflect regulatory systems that remain activated after significant environmental stress. Identifying and addressing environmental exposures is therefore an important step in restoring stability. With appropriate attention to environmental conditions, along with strategies that support nervous system regulation and physiologic recovery, many individuals see symptoms gradually improve as the body moves toward a more stable baseline.
