Are Your Workout Clothes Hiding Hormone-Disrupting Microplastics?
In our modern world, plastic is ubiquitous. From the food we eat to the clothes we wear, its presence is undeniable. While much attention is given to the chemicals in our food and beauty products, there’s an often-overlooked area where these toxins lurk: our clothing, particularly our workout wear. Many of us assume that our activewear, designed to support our fitness goals, is benign. However, it might be harboring hidden dangers. Let’s explore the potential risks of toxins in workout gear, how they might affect our health, and what steps we can take to mitigate these risks.
The Problem with Synthetic Fabrics:
Synthetic fabrics, such as polyester, nylon, and spandex, dominate the athletic wear market due to their stretchiness, moisture-wicking abilities, and durability. However, these materials are derived from petroleum, which means they often contain a cocktail of hazardous chemicals. When we sweat during exercise, our pores open, potentially increasing our exposure to these toxins.
The fashion industry uses approximately 8,000 synthetic chemicals, many of which are known endocrine disruptors. These substances can interfere with our body’s hormonal systems, leading to various health issues. Here’s a closer look at some of the most concerning chemicals found in workout clothes:
- BPA (Bisphenol A): Commonly used in plastics, BPA can also be found in some activewear. Studies have shown that BPA can leach into the body through skin contact, potentially leading to reproductive issues, cancer, and metabolic disorders.
- Flame Retardants: These chemicals are added to clothing to prevent flammability but are linked to numerous health problems. They can accumulate in the body over time, potentially affecting IQ levels in children and altering thyroid hormones during pregnancy.
- PFAS (Per- and Polyfluoroalkyl Substances): Known as “forever chemicals,” PFAS are used to make fabrics resistant to stains and water. They are persistent in the environment and have been associated with a range of health issues, including cancer and liver damage.
- Azo Dyes: These synthetic dyes are used to color fabrics but can pose health risks due to their carcinogenic properties. While banned in the EU, they are still used in many other countries.
- Formaldehyde: Used to make fabrics wrinkle-resistant, formaldehyde can cause skin irritation, respiratory problems, and, at high levels, is linked to cancer.
- Heavy Metals: Some textile manufacturers use heavy metals like lead in dyeing processes. Lead exposure can damage various organs and is particularly harmful to young children and women of childbearing age.
- Phthalates: These chemicals make plastics more flexible and are found in some synthetic activewear. They are associated with a range of health issues, including endocrine disruption and increased risk of obesity and diabetes.
What You Can Do to Reduce Exposure:
Given the potential risks, there are several steps you can take to minimize your exposure to harmful chemicals from your workout clothes:
- Opt for Natural Fibers: Choose activewear made from natural materials like organic cotton, bamboo, or merino wool. These fabrics are less likely to contain harmful chemicals and are often better for your skin.
- Check for Certifications: Look for certifications such as OEKO-TEX, which ensure that textiles are free from harmful substances.
- Invest in Quality: High-quality, durable workout gear is less likely to shed microplastics or contain toxic chemicals. Avoid fast fashion brands that may prioritize cost over safety.
- Proper Care: To reduce the release of microplastics, wash synthetic clothes less frequently, use cold water, and consider using a Guppyfriend bag or washing machine filter to capture fibers.
- Avoid Extended Wear: Remove your workout gear as soon as possible after exercising and shower to minimize the time toxins are in contact with your skin.
The Role of Sustainable Brands
Brands like Tripulse are addressing these concerns by creating activewear that is both high-performance and free from harmful toxins. Their new sports bra, for example, is made from wood-based fibers and is designed to be free from hazardous chemicals. By supporting brands that prioritize sustainability and safety, you contribute to a healthier future for both yourself and the planet.
Conclusion
Our activewear, designed to support our fitness endeavors, may be unwittingly exposing us to a range of harmful substances. By being aware of these hidden toxins and making informed choices, we can protect our health and drive demand for safer, more sustainable options in the fashion industry. Embrace natural fibers, choose certified brands, and practice mindful garment care to keep both your body and the environment healthier.
