Polyester fabrics are made from toxic precursors that are carcinogenic and poisonous, exposing both workers and the environment to health risks during manufacturing. As a plastic material, polyester contributes to the body's toxic load in ways we are just beginning to understand. It is often treated with additional flame retardants that increase this toxic load. Dust mites that live in beds and on stuffed toys feed on shed human skin and their waste affects indoor air quality, potentially triggering allergic reactions and health issues like asthma or even cancer over time due to these pollutants.
