What Your Sportswear Could Be Doing to Your Body

When you slip into your favorite leggings or sports shirt, you likely don’t think about the potential harm hidden in the fabric. However recent studies suggest that the synthetic materials commonly used in sportswear could be more dangerous than you realize. 

From cancer-causing chemicals to endocrine disruptors, here are some of the hidden dangers lurking in your workout gear:

PFAS: The Hidden Hazard in Sportswear

Your favorite leggings or sweat-wicking shirt might be doing more than keeping you comfortable; they could also deliver harmful chemicals into your body. Synthetic fabrics like Spandex, polyester, and nylon are made from petrochemicals. They are often treated with additives such as PFAS (per and polyfluoroalkyl substances).

A University of Birmingham study found that sweat can leach chemicals from synthetic fabrics, allowing them to be absorbed through the skin. 

PFAS are commonly used in water-resistant and sweat-wicking treatments. According to TorHoerman Law, these “forever chemicals” have gained notoriety due to their persistence in the environment and the human body. Their long-lasting nature has made headlines, especially as contamination has been discovered in drinking water across the U.S. and other countries. 

Much of this pollution comes from AFFF firefighting foam and improper cleanup of foam residues, causing widespread exposure.

PFAS-related lawsuits are rapidly increasing, as affected individuals and communities push to hold manufacturers accountable. The latest PFAS lawsuit update reports over $1 billion in settlements from Tyco Fire Products and BASF Corporation to address public water contamination. These developments signal a growing momentum in the legal battles surrounding PFAS exposure.

While PFAS were initially linked to firefighting foam, they are now found in everyday items, including sportswear. Recent studies found PFAS in 82% of tested outdoor apparel, such as fleece, waterproof jackets, walking boots, and rucksacks. 

As the public becomes more aware of PFAS in wearables and their link to severe health risks like cancer, pressure on manufacturers is mounting. With every new revelation, the wave of litigation grows stronger, setting a precedent for accountability and stricter regulations.

Bisphenols: The BPA of Sportswear

An increasing number of sportswear brands, including Athleta, Nike, and Champion, have been found to contain high levels of Bisphenol A (BPA). BPA is a harmful chemical linked to health issues such as asthma, cardiovascular disease, obesity, and cancer.

The Center for Environmental Health (CEH) tested various athletic wear, including leggings, sports bras, and shirts. They found some products exposed wearers to up to 40 times the safe BPA limit, according to California’s Proposition 65 standards.

Despite industry claims that BPA is safe at low levels, experts warn about its risks. This includes concerns from Tufts University, stating that both ingestion and skin absorption of BPA can lead to significant health issues.

According to CNN, CEH has filed legal notices and lawsuits against several brands, urging them to remove BPA from their products. The group recommends limiting exposure by changing out of athletic wear immediately after use.

Formaldehyde: The Cancer-Causing Preservative

Formaldehyde, a chemical commonly used in the finishing process of sportswear, serves to make fabrics wrinkle-resistant and enhance their durability. While it is effective in these roles, formaldehyde is also a known carcinogen, posing serious health risks when absorbed through the skin or inhaled. 

Prolonged exposure to this chemical has been linked to respiratory problems, skin irritation, and an increased risk of developing cancers. Formaldehyde is often found in high concentrations in outdoor gear and workout clothing. It can be absorbed during physical activity, making it a hidden and persistent threat to health.

As consumers become more aware of these dangers, the push for safer, chemical-free alternatives in sportswear is growing.

Protecting Your Health Without Breaking a Sweat

The idea that some sports accessories could be harming your health might feel overwhelming, but small, mindful changes can make a significant difference. Start by:

• Reading Labels: Look for certifications like OEKO-TEX, GOTS, or BPA-free to ensure safer materials.
• Gradual Replacements: Replace synthetic items with natural or non-toxic alternatives over time.
• Proper Maintenance: Regularly wash and clean your accessories to remove sweat and chemical residues.
• Advocating for Change: Support brands that prioritize transparency and sustainability in their products.

FAQs

What chemicals are commonly found in sportswear?

Sportswear often contains harmful chemicals like BPA (Bisphenol A), formaldehyde, PFAS (per- and polyfluoroalkyl substances), phthalates, and bisphenols. These chemicals are used for various purposes such as making fabrics durable, wrinkle-resistant, and water-resistant, but they pose significant health risks.

Can I avoid harmful chemicals in my sportswear?

To reduce exposure, consider choosing brands that offer products made from organic or safer materials. Be cautious of synthetic fabrics like polyester, spandex, and nylon, which are more likely to contain harmful chemicals. Also, washing your activewear frequently can help reduce chemical buildup, though it doesn’t eliminate all risks.

Are there any legal actions being taken against sportswear brands for these chemicals?

The Center for Environmental Health (CEH) has filed legal notices and lawsuits against several sportswear brands. These actions are for selling products that contain harmful chemicals such as BPA and PFAS. These efforts aim to push manufacturers to reformulate their products for safer consumer use.

Overall, by being mindful of what we use during our workouts, we can protect our health. This ensures that our efforts to stay fit extend beyond the gym and into every aspect of our lives.

After all, true fitness isn’t just about how we treat our bodies; it’s also about what we put on and around them.
