Summary
This study looks at how common chemicals in personal care products, processed foods, and synthetic materials affect skin, gut, and airway health. One hundred twenty healthy adults will stay in a controlled hospital room for two 7-day periods—one with filtered air and pure products, and one with everyday exposures. Researchers will measure changes in skin, gut, and lung function to understand links to allergic and inflammatory conditions.
