From yoga leggings to sports bras to muscle tanks, women’s activewear is a $120 billion industry. Along with this growth comes a demand for high performing fabrics, and some of these fabrics are damaging the environment as well as our health. By choosing activewear made from organic fabric, you can protect our planet and avoid unnecessary exposure to  endocrine-disrupting PFAS chemicals that are found in some fitness fabrics.

How Is Women’s Activewear Damaging The Environment?

Activewear fabrics like polyester, nylon, acrylic and lycra don’t break down in landfills for hundreds of years or more. When they do break down, they can leach tiny plastic particles, called microplastics, that migrate all over the world, mixing in with dust and sand and traveling though ocean water. Microplastics can be found in marine animals, table salt and our drinking water, among other things.

If your activewear fabric isn’t organic, chances are it’s been sprayed with pesticides. Seven of the 15 pesticides commonly used on cotton in the United States are listed as “probable” or “known” human carcinogens by the Environmental Protection Agency.

Farming with organic practices keeps our waterways free from harmful herbicides and pesticides & encourages pollinators to visit crops, and keep the bees, butterflies and birds safe from harmful chemicals. Organic farming also reduces water use and non-renewable energy use compared to conventional farming.

PFAS Chemicals In Women’s Activewear

Just like in the outdoor clothing industry, the women’s activewear industry covets fabric that wicks sweat, is quick drying, and is water and stain resistant. These high-performing fabrics may contain chemicals like PFAS that can be damaging to your health.

Environmental Health News and Mamavation teamed up for a study on detectable levels of organic fluorine in women’s activewear leggings and sports bras. The presence of organic fluorine is an indicator that the fabric contains or is coated with PFAS chemicals. They found that 25% of the activewear tested had detectable levels of fluorine, an indication of PFAS, and 65% of sports bras came back with indications of PFAS.

Can We Be Exposed To PFAS Chemicals Through Dermal Exposure?

Unfortunately, studies in this area are lacking, so we don’t know the long-term effects of dermal exposure to PFAS. One study looked at fluorinated elements in car seats and found that PFAS can migrate from the fabric to sweat, suggesting a dermal route of PFAS exposure (1).

Another study used a murine animal model to measure dermal PFBA exposure and effects on the liver, and the findings indicate a dermal pathway to exposure (2).

If you’re a nursing mama, I recommend using a PFAS-free sports bra in order to reduce your baby’s exposure to PFAS chemicals.

Health Risks Associated With PFAS Exposure

After a community in Parkersburg, West Virginia was exposed to PFAS chemicals in their drinking water, here are some of the documented health risks associated with exposure to PFAS: testicular cancer, thyroid disease, high cholesterol, ulcerative colitis and other health problems. Further research has associated PFAS with more health risks, including increased risk of asthma, immune system disfunction, decreased vaccine response in children, changes in liver enzymes, increased risk of high blood pressure and pre-eclampsia in pregnant women, small decreases in infant birth weight and weight gain in adults (3).

The good news is that not all of the activewear tested in the study was positive for the presence of PFAS chemicals. Although it is possible for organic fabric to contain PFAS chemicals, the Environmental Health News and Mamavation study found that “sports bras made from synthetic fabrics like polyester or rayon were more likely to be found with detectable organic fluorine.”

I’m sharing 4 women’s activewear brands that are sustainably made with organic fabric to lower your impact on our environment while you’re working out. The Pact brand of women’s activewear had zero fluorine detected from the Environmental Health News and Mamavation study (in the leggings and sports bra), and the other brands were not included in the study.
