Let's talk about a topic that might make you rethink your workout wardrobe: the presence of PFAS in activewear, specifically leggings. PFAS, or 'forever chemicals', are a concern due to their potential health risks and environmental impact. These chemicals are notoriously persistent, taking an incredibly long time to break down, which means they accumulate in our environment and, worryingly, in our bodies.
The investigation into Lululemon, a popular activewear brand, by the Texas attorney general, has brought this issue to the forefront. The brand is under scrutiny for potentially misleading consumers about the safety and health impacts of its products, particularly regarding PFAS content. This raises important questions about transparency in the fashion industry and the potential health risks associated with our everyday choices.
So, how worried should we be about PFAS in our leggings? Well, it's a complex issue with no simple answer. While we don't fully understand how PFAS permeates the skin, especially in areas like the crotch where the skin is thinner, research suggests that wearing PFAS-containing leggings could contribute to overall exposure. Every time we wash these items, PFAS can shed and end up in our wastewater, potentially returning to our drinking water supply.
PFAS exposure has been linked to various health issues, including immune system problems, liver function impairment, and certain types of cancer. However, it's important to note that the amount of exposure from leggings is likely a small part of our overall PFAS intake. Our diet and drinking water are more significant sources of exposure.
Scientists are still researching the full extent of PFAS health effects, but in the meantime, there are steps we can take to reduce our exposure. Using water filters, choosing hard floor coverings over carpets, and making dietary changes like increasing fiber intake can all help. Additionally, donating blood can reduce PFAS levels in the body, although it's important to note that this transfers PFAS to the recipient.
Activewear brands use PFAS for their stain- and water-resistant properties, but these chemicals can also be unintentionally added during the manufacturing process. It's a challenging issue, as even brands advertising PFAS-free products may still have trace amounts due to the complexity of the supply chain.
So, how can we identify PFAS-free leggings? Unfortunately, most labels don't disclose PFAS content, so we need to look for specific certifications. The OEKO-TEX certification, for example, ensures a product is free from over 1,000 harmful chemicals, including intentionally added PFAS. The Global Organic Textile Standard (GOTS) certification is another indicator, as it prohibits the use of PFAS.
There are brands making strides in this area. Mate The Label, for instance, has a GOTS certification and explicitly labels its products as PFAS-free. LNDR holds an OEKO-TEX certification, and REI announced in 2023 that its clothing products would be PFAS-free. These brands offer alternatives for those concerned about PFAS exposure.
In conclusion, while the presence of PFAS in leggings is a valid concern, it's just one piece of a larger puzzle. Our everyday choices, from the water we drink to the floors we walk on, all contribute to our overall exposure. By staying informed, seeking out PFAS-free alternatives, and making conscious choices, we can work towards reducing our exposure to these 'forever chemicals'. It's a complex issue, but one that we can navigate with the right information and a bit of vigilance.
