Yes, some clothing can contain endocrine-disrupting chemicals (EDCs) that may interfere with the bodyās hormonal system. These chemicals can be present due to manufacturing processes, treatments, or materials used in textiles. Hereās a concise overview:
- Common EDCs in Clothing:
- Phthalates: Used in plastic-based textiles or prints (e.g., PVC coatings), these can disrupt hormone function, particularly affecting reproductive health.
- Per- and Polyfluoroalkyl Substances (PFAS): Found in water-repellent or stain-resistant clothing, PFAS are linked to thyroid and reproductive hormone disruption.
- Bisphenols (e.g., BPA): Sometimes present in polyester or plastic components, these can mimic estrogen.
- Azo Dyes and Heavy Metals: Certain synthetic dyes and finishes may contain compounds like aniline or heavy metals (e.g., cadmium, lead), which can act as EDCs.
- Formaldehyde: Used in wrinkle-resistant or flame-retardant treatments, it may disrupt hormonal balance at high exposure levels.
- How Exposure Happens:
- Skin contact: EDCs can be absorbed through the skin, especially in tight or frequently worn clothing.
- Washing: Chemicals may leach into water, affecting the environment or remaining on clothes.
- Inhalation: Dust or volatile compounds from treated fabrics can be inhaled.
- Evidence and Concerns:
- Studies (e.g., Greenpeaceās 2014 āDirty Laundryā report) have detected EDCs like PFAS and phthalates in clothing from major brands, particularly in fast fashion.
- Animal and lab studies suggest EDCs can affect thyroid, reproductive, and metabolic systems, though human health impacts from clothing-specific exposure are less studied and depend on exposure levels.
- Reducing Exposure:
- Choose natural, organic fibers (e.g., organic cotton, hemp) certified by standards like GOTS (Global Organic Textile Standard).
- Wash new clothes before wearing to reduce chemical residues.
- Avoid clothing with āperformanceā claims (e.g., waterproof, stain-resistant) unless certified PFAS-free.
- Opt for brands transparent about chemical use or those avoiding known EDCs.
