Synthetic clothes—like polyester and nylon—are often assumed harmless. Yet mounting evidence shows they may pose hidden health risks, from skin irritation to hormonal disruption.
When I was young, my dad had lease cars for work. Every few years—maybe three, maybe five—he could choose a new one and customize it. He always involved us, which was exciting. But when the new car arrived, I couldn’t bear the smell. No matter the season (I’m from the Netherlands), we had to drive with the windows open—or I’d feel sick.
My dad also had one perfume I couldn’t stand—especially in the car. Again, windows open. It made me nauseous. Now I know: these were reactions to chemicals.
Little did I know that, as I grew up, we’d be surrounded by even more hidden toxins. I’ve just turned 40, with two children of my own. And just like we all are, they’re growing up around plastics, synthetic materials, and endocrine-disrupting chemicals—many of them hiding in our clothes.Yes—our clothes are poisoning us. And while that’s a terrifying thought, there are things we can do about it.
My Health Wake-Up Call
In 2009, in my final year of art school—my seventh year studying fashion—I was 24 and decided to stop taking birth control. But after months, my period didn’t return.
There was a myth going around that this was normal—that your body just needed time to adjust after years of hormones. But that’s just it—a myth. Your body should be able to resume its natural cycle once you stop introducing artificial hormones.
After several tests and scans, I was diagnosed with PCOS (Polycystic Ovary Syndrome). But before birth control, my cycle was regular. I also didn’t have other common symptoms like excess hair growth or weight gain.
What I did have? Years of unexplained hair loss. Doctors ran tests, found nothing. “Some women just have this,” they told me.
I refused to accept that.
At 25, I began a personal health journey—acupuncture, Ayurveda, clean products. If traditional medicine wouldn’t help me, I’d help myself.
I was on a tight budget but prioritized essentials. First, I switched to clean skincare—because what goes on your skin, your largest organ, matters. Then laundry detergent. I’ve always been sensitive to synthetic scents, so I also replaced my perfume. I couldn’t always afford organic vegetables, but I invested in good staples like rice, pasta, potatoes.
Years later, still in Beijing and just before moving to Singapore, I got a full medical screening under Dutch health insurance.
And guess what?
No more PCOS.
Of course, a lot had changed in 10 years—but it confirmed something I had always suspected: your health is not fixed. You have influence over it. And going natural is part of that.
The Hidden Dangers of Toxic Clothes
I’ve always struggled with synthetic fabrics. Even yoga wear makes me feel like I can’t breathe. It’s not an allergic reaction—more like discomfort I can’t explain.
And I’m not alone.
Remember the lawsuit a few years ago, when American Airlines introduced new uniforms? Flight attendants developed rashes, respiratory problems, brain fog, and even long-term illness. Some cases were fatal. The uniforms were marketed as “high-performance”: wrinkle-free, water-repellent, anti-odor.
But all those finishes come at a cost: PFAS (also known as “forever chemicals”), phthalates, formaldehyde, azo dyes—just to name a few.
The thing with toxic exposure is that it builds up. One day you’re fine. The next, you can’t tolerate the shirt you wore last week, or even the perfume on the person next to you.
My car story? Probably a chemical sensitivity I’ve had all along. I still avoid taxis when I can—the artificial air-fresheners make me nauseous for hours.
Synthetic clothing affects people differently. But if you have symptoms with no clear medical explanation, consider your wardrobe:
- Rashes or skin irritation
- Sneezing, congestion, or itchiness
- Nausea, fatigue, or brain fog
- Headaches after wearing certain fabrics
Women are often more affected—maybe because we wear more synthetic materials, often unknowingly. That breezy dress you love? It may be full of invisible toxins.
Feeling Overwhelmed? You’re Not Alone.
This might sound like a lot. Maybe you’re picturing a life off the grid, weaving clothes from banana leaves and drinking from coconuts. I’ve been there.
After reading To Dye For by Alden Wicker, I spiraled. I thought of my toddlers drinking from plastic bottles—BPA-free or not—in Singapore’s endless heat.
I felt hopeless.
But here’s the thing: we can’t eliminate all toxins, but we can reduce our exposure. Every small, mindful step matters.
What You Can Do
I get it—chemicals are everywhere. They’re in our clothes, our paint, our furniture. They’re cheap and convenient. But that doesn’t mean we have to invite them into our bodies.
Unlike skincare or food, clothing doesn’t come with an ingredient list. And that’s a problem—because fashion is one of the most chemically treated industries in the world.
Here’s where to start:
- Phase out synthetic fabrics.
Polyester, nylon, acrylic, Lycra—all plastic-based. Even the stretch in jeans. You don’t need to go cold turkey, but try to reduce. - Remake what you love.
Tailors can copy your favorite top in organic cotton, linen, hemp, or silk. Especially doable in Asia. - Avoid high-performance finishes.
Stain-resistant, wrinkle-free, moisture-wicking—all marketing terms for chemical coatings. Learn to remove stains naturally instead. - Wash before you wear.
New clothing often contains residual chemicals from dyeing and finishing. Always give it a rinse—even if it’s “natural.”
Rethink dry cleaning.
Most garments labeled “dry clean only” can be hand-washed or cold washed. Conventional dry cleaning uses perchloroethylene, a known carcinogen (anything that increases the risk of cancer).
The Bottom Line
We now know that microplastics are in our bloodstream, our lungs, even our babies. I once read we ingest a credit card’s worth of plastic each week. Whether that’s true or not, the direction is clear.
But knowledge is power.
If today you choose one small change—switching laundry detergent, reading tags more carefully, or wearing more natural fibers—you’re already doing something.
Your body will thank you.

FAQs
What does “synthetic clothing” mean?
Synthetic clothing is made from man-made fibers like polyester, nylon, spandex, and acrylic. These are derived from petroleum and often treated with chemical finishes to improve performance or appearance.
Are synthetic fabrics harmful to skin or health?
Yes. They can contain endocrine disruptors like phthalates and PFAS, which have been linked to hormonal imbalance, fertility issues, and more. Some dyes and finishes can also cause skin irritation or allergic reactions.
Which fabrics are safest to wear?
Look for organic cotton, linen, hemp, silk, and untreated wool. Natural fibers allow your skin to breathe and are usually free from harmful chemicals—especially when GOTS or OEKO-TEX certified.
Is polyester toxic to wear?
Polyester is a plastic. It’s non-breathable and often treated with toxic finishes. It may not immediately irritate everyone, but long-term exposure—especially when sweating—can release volatile organic compounds (VOCs) and contribute to health issues.
Are all synthetic fabrics bad for you?
Short answer: Yes. All synthetic fabrics are made from plastic — oil-derived and man-made. That includes polyester, nylon, acrylic, and elastane (spandex). Even though you might hear arguments that some synthetics are “better” than others, the reality is: none of them are natural, and none are great for your health.
Yes, vintage synthetics often feel better — they might drape differently or be more breathable — but they’re still plastic. Whether it’s 1970s polyester or 2025 recycled nylon, it doesn’t change the core issue. Wearing plastic against your skin all day affects your body and the environment.
Which synthetics are the least bad?
Let’s be honest: we need performance fabrics sometimes. You probably don’t want to swim in a cotton bikini or run a marathon in linen. There are moments where synthetics make functional sense. But they’re still not ideal for all-day wear.
So if you do wear synthetics — keep them for short bursts. Not for lounging, sleeping, or daily wear if you can avoid it. Let your body breathe.
