How Your Clothes Might Be Affecting Your Health
If you’ve ever watched the 2006 film The Devil Wears Prada, you might recall a moment when a character working at a prestigious fashion magazine makes a curt remark to the new employee, suggesting she must have “plenty more poly-blend where that came from.” But why exactly is polyester considered undesirable, and could it actually have an impact on your health?
Polyester is a synthetic (man-made) material created by melting down plastic derived from petroleum. While it is a common and affordable fabric, recent studies suggest that it may have unintended consequences for both human health and the environment.
Uncovering the Risks of Polyester
A major concern with polyester and other synthetic fabrics is that they shed microplastics—tiny plastic particles—every time they are worn and washed. In fact, it’s estimated that around half a million tons of plastic microfibers enter the ocean annually from washing plastic-based textiles such as polyester, nylon, and acrylic (A New Textiles Economy Report, 2017). These microplastics do not break down easily, and researchers are still studying their long-term effects on human, animal, and environmental health.
What Are Microplastics, and Why Are They Harmful?
Microplastics are minuscule fragments of plastic, typically smaller than 5mm (about twice the size of an infectious virus), that pollute the air, water, and soil. Over time, they accumulate in the human body, where they have been detected in organs such as the liver, kidneys, placenta, and testes. Researchers at the University of New Mexico Health Sciences have even found microplastics in the human brain at much higher concentrations than in other organs. Worryingly, their presence in the body appears to be increasing, with levels rising by 50% over the past eight years.
Polyester and Your Skin
One of polyester’s most well-known features is its moisture-wicking ability, which makes it a popular choice for workout clothes. However, since the fabric is not breathable, sweat becomes trapped between the material and your skin. This creates a damp environment where bacteria thrive, leading to body odor. Additionally, odors can become embedded in polyester and persist even after washing. Some people may also develop an allergy or sensitivity to polyester, which can cause rashes, irritation, or itchiness.
Researchers are examining a possible link between polyester and cancer cells, but they need more time and information to study. As of now, there are conflicting reports about whether or not polyester is carcinogenic.
Since polyester is derived from plastic and does not break down naturally, studies have also found that certain synthetic textiles contain per- and PFAS (polyfluoroalkyl substances), labelled “Forever Plastics” because they will be on Earth forever. These chemicals have been linked to health concerns such as hormonal disruption, weakened immune function, and an increased risk of certain cancers. Some studies suggest that PFAS can enter the bloodstream through prolonged skin contact with synthetic fabrics.
Women’s Health and Synthetic Fabrics
For women, non-breathable fabrics like polyester may cause discomfort or health issues in sensitive areas. Many gynecologists and primary care physicians recommend wearing 100% cotton underwear to help maintain a balanced vaginal pH. A disrupted pH level can lead to unpleasant diagnoses such as bacterial vaginosis, yeast infections, urinary tract infections, and general irritation. Even if you wear cotton underwear, covering it with polyester-based leggings or pants can reduce breathability and increase the risk of discomfort.
The Benefits of Natural Fibers
Natural fibers come from renewable sources such as plants and animals, making them biodegradable and more breathable than synthetic fabrics. These materials do not shed harmful microplastics and are typically more comfortable against the skin. Choosing natural fibers can reduce your exposure to synthetic chemicals.

Synthetic Fibers to Be Cautious Of:
While synthetic materials serve specific purposes, they are non-breathable and not biodegradable. Some common synthetic fabrics include:
- Acrylic
- Nylon
- Spandex
- Rayon
Making an Informed Choice
The skin is the body’s largest organ, so try to treat it with respect and keep it healthy. The next time you shop for clothing, take a moment to read the inner tag and find the source of your fabric. Choosing natural fibers may not only be a healthier choice for your body but also a more sustainable option for the planet. Plus, they tend to be much more comfortable!
