Is Polyester Bad? Why I’m Reconsidering it and Making Healthier Fabric Choices

Transitioning everyday essentials—clothing, linens, and more—to natural fibers.

A Wake-Up Call About Everyday Materials

My journey into learning about the impact of polyester started with an unexpected revelation: a toxin panel showed my body had 29,000% elevated levels of propylene oxide. Like most people, I never really considered how the synthetic materials around me—my clothing, bedding, and furniture—might be affecting my health. I assumed that since we’re surrounded by plastics and synthetic fabrics every day, they must be harmless, right? But that test result made me pause and re-evaluate… Is polyester bad?

At the time of my cancer diagnosis, my wardrobe was filled with polyester blends. I traveled often and had a fast-paced lifestyle, so I prioritized convenience—wrinkle-resistant, quick-drying clothes that required little upkeep. My home was no different—polyester-filled pillows, a memory foam mattress, and synthetic fabrics everywhere. It wasn’t that I was actively ignoring the issue; I just didn’t realize it mattered.

Shifting My Perspective

For years, I was deeply invested in natural living, carefully choosing organic foods and non-toxic personal care products. But somehow, I had completely overlooked textiles. Cancer changed that. It made me rethink not just what I was eating but what I was wearing and sleeping on every day.

That being said, I don’t beat myself up over the past, because I know I’m not alone. Polyester is everywhere—it’s affordable, durable, and convenient. The reality is, most people simply don’t know much about the materials they interact with daily. But once I started learning, I realized I had more power than I thought to make better choices when possible.

This isn’t about eliminating polyester entirely in one fell swoop (because let’s be honest, that would be difficult and expensive!). It’s about awareness and making thoughtful swaps where it makes sense. So, let’s explore what polyester actually is, why it’s worth paying attention to, and simple ways to reduce exposure without feeling overwhelmed.

What Exactly is Polyester?

Polyester is a synthetic fiber derived from petroleum. First developed in the 1940s, it became popular due to its durability, affordability, and resistance to wrinkles. Today, polyester is found in everything from clothing and bedding to carpets and furniture. But at its core, polyester is plastic—something we wouldn’t normally associate with comfort or breathability.

Beyond its synthetic nature, polyester also raises concerns about the chemicals often used in its production. Fast fashion brands like Shein have come under scrutiny for containing toxic substances in their clothing. Investigations revealed that some Shein products, including children’s items, contained hazardous chemicals such as phthalates and lead at levels far exceeding legal safety limits. In one case, authorities in Seoul found phthalate levels 428 times above the permitted limit. These discoveries have sparked concerns over the potential health risks of wearing such garments, prompting regulatory agencies to push for stricter safety standards in the fast fashion industry.

Like all synthetic materials, polyester has its pros and cons. While it’s convenient, cost-effective, and widely accessible, it also comes with health and environmental considerations. Understanding these factors has helped me strike a balance—finding ways to enjoy modern conveniences while making mindful choices that better support my health and well-being.

Making More Informed Choices About Polyester

1. Choosing Fabrics That Breathe

One of the first things I noticed after switching to more natural fibers was how much better my skin felt. Polyester doesn’t breathe the way cotton, linen, or wool do, and I immediately noticed how much more comfortable I was when I wore natural materials. I still own polyester-based activewear, but I make sure not to wear it for long periods after workouts. Small changes like this made a noticeable difference in how my body responded.

Easy swap: Try incorporating more breathable fabrics like cotton, linen, hemp, or wool in everyday wear, especially for items worn for long periods, like sleepwear and loungewear.

2. Thinking Beyond Clothing—Polyester in the Home

Polyester isn’t just in clothing—it’s in our bedding, furniture, and carpets. I hadn’t given much thought to this before, but when I started learning more, I realized that making mindful swaps in my home could have just as much impact as changing what I wear.

One of the biggest changes I made was replacing my polyester bedding with cotton and natural alternatives. This wasn’t an overnight change, but as I replaced worn-out items, I chose natural fibers instead. The result? Better sleep and a noticeably fresher feel to my bedding. It’s also not bad looking either!

Easy swap: If replacing everything at once isn’t realistic, start small—switching to organic cotton pillowcases or sheets is an easy first step.

3. Supporting a More Sustainable Approach

Another consideration for me was the environmental impact of polyester. Because it’s a plastic-based material, it doesn’t biodegrade like natural fibers. Additionally, washing polyester releases microplastics into the water supply, contributing to pollution. While avoiding polyester completely isn’t feasible, there are small steps we can take to be more conscious consumers.

Easy swap: Using a microfiber-catching laundry bag or installing a washing machine filter helps reduce the number of microplastics released when washing synthetic fabrics.

4. Finding a Balance That Works

One of the most important things I’ve learned on this journey is that it’s not about perfection—it’s about progress. I still own some polyester clothing. I still have a couch with synthetic upholstery. The difference is, now I make more informed choices when I have the opportunity.

Instead of stressing over what I can’t change, I focus on what I can. With each purchase, I ask myself:
"What’s the best option available to me right now?"

Sometimes that means choosing an organic cotton sweater instead of a polyester one. Other times, it means holding onto an existing polyester item instead of replacing it unnecessarily. There’s no one-size-fits-all solution, and that’s okay.

Conclusion: Small Changes, Big Impact

My experience with cancer pushed me to reevaluate many aspects of my life—including the materials I surround myself with. But this isn’t about fear—it’s about awareness. Making more thoughtful choices about fabrics has improved my comfort, my health, and my overall sense of well-being.

The best part? These changes don’t have to be overwhelming. Whether it’s swapping out one or two items, choosing more natural fibers when shopping, or simply being mindful of how polyester interacts with our bodies and homes, every small step makes a difference.

The goal isn’t to eliminate polyester completely (but if you can, props to you!) —it’s to make better choices when possible. And that’s something we can all feel good about.
