BPA and in Activewear and Its Link to Breast Cancer
In today's world of high-performance activewear, we expect our workout gear to be breathable, stretchy, and durable. But what many don't realize is that some of these features come with a hidden cost—exposure to harmful chemicals like BPA (Bisphenol A). Increasing evidence suggests that chemicals in clothing, including some activewear, may contribute to long-term health risks, including breast cancer.
The Chemical Problem in Activewear
What is BPA? BPA is a synthetic chemical commonly found in plastics and resins. It’s often used in the manufacturing of polyester, a common fabric in activewear, and can be present in water-resistant or sweat-proof coatings. BPA is a known endocrine disruptor, meaning it mimics or interferes with the body’s hormones, particularly estrogen. Elevated estrogen levels can increase the risk of breast cancer.
Why is it in activewear? Activewear is designed to perform under demanding conditions, which often requires the use of synthetic fabrics and chemical treatments for moisture-wicking, stretch, and durability. Unfortunately, these chemical treatments often include harmful substances like BPA, phthalates, and PFAS (per- and polyfluoroalkyl substances), all of which have been linked to health issues, including hormone disruption and cancer risks.
The Breast Cancer Connection Research suggests that chronic exposure to hormone-disrupting chemicals like BPA can increase the likelihood of developing breast cancer. Because activewear is typically worn close to the skin for extended periods—especially during sweaty workouts—there is a higher potential for the body to absorb these chemicals through the skin. Over time, even low-level exposure can accumulate, contributing to health risks.
How to Choose Safer, Nontoxic Activewear
Thankfully, there are steps you can take to reduce your exposure to harmful chemicals in activewear. Here are practical tips for making healthier, more informed choices:
- Look for Natural Fibers Opt for activewear made from plant-based fabrics like organic cotton, Tencel, and hemp. These materials are naturally breathable, moisture-wicking, and free of harmful chemicals. They also decompose naturally, making them more environmentally friendly.
- Avoid Clothing Labeled as “Stain-Resistant” or “Water-Repellent” These types of coatings often contain PFAS or other chemical treatments that can persist in the environment and may pose health risks. Instead, choose untreated fabrics that allow for natural breathability and sweat-wicking properties.
- Check for Certifications When shopping for activewear, look for certifications like OEKO-TEX Standard 100, GOTS (Global Organic Textile Standard), and bluesign®. These labels indicate that the fabric has been tested for harmful substances and is produced in environmentally and socially responsible ways.
- Go BPA-Free Some brands (like Reprise!) are BPA-free. Be sure to research the materials listed on the label, and check the brand’s transparency regarding chemical usage.
- Wash New Clothes Before Wearing Washing new activewear before its first wear can help reduce your exposure to residual chemicals used during the manufacturing process. Cold water and gentle detergent are often best to preserve the integrity of the fabric.
- Support Brands That Prioritize Sustainability and Health Brands that are committed to sustainability often pay close attention to the chemicals used in their fabrics. These companies tend to be more transparent about their production processes and are likely to use safer, nontoxic materials.
Conclusion: Protect Your Health and the Planet
As more research links chemicals like BPA to breast cancer, it's becoming increasingly important to be mindful of the materials we wear, especially during exercise when our skin is more likely to absorb these chemicals. Choosing safer, nontoxic activewear not only protects your health but also supports environmentally sustainable practices.
By opting for natural fibers, certified fabrics, and sustainable brands, you can enjoy the benefits of high-performance activewear without exposing yourself to unnecessary risks. Always prioritize your health by being selective about what you put on your body—and the planet will thank you too.
