PFAS Chemicals in Period Underwear: The Basics
What Are PFAS?
PFAS are a group of synthetic chemicals that might be used in period underwear to make them more absorbent or stain-resistant. The problem? These chemicals have been linked to various health issues, including fertility challenges. If becoming a parent is part of your plans for the future, this information is particularly relevant.
PFAS, or per and polyfluoroalkyl substances, are a group of man-made chemicals linked to various health problems, including cancer, thyroid disease, and infertility. These chemicals are found in everyday products, including some period underwear.
Manufacturers may unknowingly include PFAS through the raw materials they source from suppliers, highlighting the need for greater transparency and regulations. A 2020 class action lawsuit against Thinx, a popular period underwear brand, alleged the intentional addition of PFAS in their products. This raised awareness of potential health risks associated with PFAS in menstrual products.
Properties Of PFAS
They have been used in a wide range of products for their water- and stain-resistant properties. From non-stick cookware to waterproof clothing, PFAS have been utilized for their unique ability to repel liquids.
In the context of period underwear, PFAS may be appealing to manufacturers because of these same properties. Stain resistance and absorbency are key features for such products, and PFAS can enhance these characteristics. However, what might seem like a practical choice from a design perspective has raised serious health concerns. The ongoing efforts by the Environmental Protection Agency to regulate and limit the presence of PFAS in consumer goods highlight the importance of addressing these concerns.
Protecting Your Health and the Environment
Choosing PFAS-free period underwear is a more sustainable approach that protects your health and the environment. PFAS can contaminate drinking water and food packaging. Studies have linked repeated exposure to these chemicals to various health problems, including increased cholesterol levels, weakened immune systems, and even birth defects. The presence of total fluorine can sometimes identify the presence of PFAS detected through testing, although more sophisticated methods are needed for definitive confirmation.
While not all menstrual products contain PFAS, research from Peaslee’s lab has found it in some incontinence pads along with period underwear. This highlights the importance of choosing PFAS-free options whenever possible. A study suggests that exposure to PFAS during pregnancy may be linked to an increased risk of low birth weight in babies.
However, more research is needed to confirm this link. It’s important to note that PFAS are found in many other everyday products, such as nonstick cookware and certain cleaning supplies. Choosing PFAS-free alternatives whenever possible can help reduce your overall exposure to these chemicals.
New Research on PFAS in Period Underwear
Recent studies have shed more light on the prevalence of PFAS in menstrual products. Testing by independent labs commissioned by organizations like Environmental Health News found that nearly half of all products tested, including pads, tampons, and Thinx products, contained PFAS.
This raises concerns about public health, especially since the 2020 lawsuit against the Thinx brand alleged the company’s PFAS-containing menstrual underwear misled customers about the safety of their products. These chemicals, also known as per-and-polyfluoroalkyl substances (PFAS), are a group of man-made chemical compounds linked to various health problems, including weakened immune systems and certain cancers.
While more research is needed to fully understand the specific health outcomes associated with exposure to PFAS in menstrual products, this new information highlights the importance of choosing PFAS-free menstrual underwear whenever possible. It’s essential to consider the potential risks, especially for pregnant people who may be more susceptible to certain health effects of PFAS exposure.
Is Period Underwear Toxic? Not All of Them Contain Harmful Chemicals
Before panic sets in, it’s essential to understand that not all menstrual products, including period underwear, contain these chemicals. The question itself is indeed concerning but requires a nuanced answer.
Many brands are committed to avoiding PFAS and other toxic substances, focusing on natural and organic materials. These companies understand that knowing about PFAS in period underwear is a priority for consumers, and they actively work to provide safe alternatives.
Organic fluorine is often used as an indicator for the presence of PFAS in testing, as it is easier to detect, and a positive result suggests PFAS contamination. The use of PFAS is not universal across all period underwear. Many manufacturers recognize the importance of avoiding these chemicals, particularly when it comes to women’s reproductive health.
There are, in fact, a plethora of options available for those who want to steer clear of potential toxins in their period underwear. This means you don’t have to abandon the convenience and comfort of these products altogether.
If fertility is a concern, carefully researching the brands and their materials can put your mind at ease. Look for brands that explicitly state their commitment to PFAS-free production and those that use organic fabrics and responsible manufacturing processes.
Labels such as “organic,” “natural,” or “toxin-free” can indicate safer choices, though it’s always wise to dig deeper and confirm the company’s practices.
Increased Risk of Infertility
Studies have shown that PFAS can interfere with a woman’s body in several ways, affecting hormone levels and menstrual cycles. These disruptions can harm human health, leading to difficulties in conceiving and might even influence the health of a future child. PFAS chemicals have been linked to longer menstrual cycles, a decrease in the number of viable eggs, and changes in hormone levels that can diminish fertility.
The way PFAS impacts fertility is complex and multi-faceted. First, they can disrupt the endocrine system, affecting hormones like estrogen and progesterone, essential in regulating ovulation and pregnancy. By altering these hormones, PFAS can affect the regularity of menstrual cycles, leading to unpredictable periods that may make it more challenging to conceive.
Additionally, PFAS exposure has been linked to high blood pressure, which can further complicate pregnancy.
Effect Of PFAS On Ovaries
Second, PFAS may directly affect the ovaries and reduce the quality of a woman’s eggs. Research has shown that exposure to these chemicals can decrease the number of eggs retrieved in fertility treatments, suggesting a concerning impact on ovarian reserve. This can lead to a higher risk of miscarriages and other complications in conception. Moreover, PFAS exposure increases the risk of certain health issues, including high blood pressure in pregnant individuals and potential impacts on fetal health and development.
Furthermore, there’s evidence to suggest that PFAS exposure during pregnancy might result in lower birth weight and may even have long-term effects on a child’s immune system and development.
In addition to the direct risks to reproductive health, the anxiety and stress associated with fertility struggles can further exacerbate the situation, creating a challenging cycle that affects both mental and physical well-being.
For those considering pregnancy, understanding the potential risks associated with PFAS in period underwear and other products becomes essential. The growing body of research continues to uncover the multifaceted ways these chemicals might affect reproductive health, leading to greater awareness and desire for products that are free from these harmful substances.
