That sunny window trick? Try it right now.
Dr. Lisa Erdle from 5 Gyres broke down what's actually happening when you wear synthetic fabrics, especially the ones you sweat in. Those colorful specks of dust floating in the light aren't just dust. They're microfibers shedding from your clothes, and some end up in your lungs and even your nasal passageways.
Then there's what's on the fabric itself. Textiles carry 5,000 to 6,000 different chemicals for dyes, flame resistance, waterproofing. When you sweat and your pores open up, some of those chemicals can move from the fabric into your skin.
This is part of our conversation with Dr. Erdle for Plants Over Plastics Collective, more in our Stories.
Ever noticed those fibers floating in a sunny window?
