Dry Cleaning Chemical Found to Harm Brain Cells and Raise Parkinson's Risk

A study of more than 1.3 million Americans found that people living in areas with high trichloroethylene (TCE) levels had a 10% greater risk of Parkinson's disease than those in cleaner regions TCE, a solvent once used in dry cleaning and degreasing, persists in air, soil, and groundwater for decades, exposing people through contaminated water and indoor air — even far from industrial sites Laboratory research revealed that TCE damages dopamine-producing neurons, disrupts mitochondrial energy production, and causes toxic protein buildup like that seen in Parkinson's patients The studies show that chronic, low-level exposure to environmental toxins silently erodes brain health over time, especially in older adults with weakened cellular repair systems Reducing exposure through clean water, good ventilation, and low-toxin household choices — while supporting your cells through restorative sleep, regular movement, and whole, unprocessed foods — helps protect mitochondrial energy production and strengthen long-term neurological resilience
