(Un)Healthy Homes

In this powerful episode of The Building Science Podcast, host Christoph Erwin dives deep into the critical intersection of indoor environments and human health with Dr. Eva King, a leading indoor environmental consultant and founder of ARA EnviroScience LLC. The conversation centers on how modern homes—designed primarily for aesthetics and cost-efficiency—often become 'coal mines' for health-damaging pollutants, particularly for the growing number of individuals with heightened sensitivities. Dr. King shares her journey from academic research to founding her own consulting practice, emphasizing how the pandemic shifted her focus from commercial projects to residential clients, many of whom suffer from conditions like Chronic Inflammatory Response Syndrome (CIRS), Multiple Chemical Sensitivity (MCS), and Pediatric Acute Onset Neuropsychiatric Syndrome (PANS). She explains that these conditions, while complex and not yet fully understood by mainstream medicine, often stem from prolonged exposure to biotoxins in water-damaged buildings. A key theme is the 'canary in the coal mine' metaphor: highly sensitive individuals serve as early warning systems for systemic building failures, revealing hidden dangers that affect everyone. Dr. King stresses that buildings must be viewed as integrated systems—where moisture control, ventilation, and occupant behavior are interdependent—and warns against ineffective or harmful 'solutions' like ozone and hydroxyl generators. The episode concludes with a moving reflection on the importance of empathy, trust, and effective communication in helping families navigate the emotional and physical toll of unhealthy homes.
