Micro Plastics Everywhere

Microplastics are one of the most talked-about environmental crises right now. What most people don't realize is that a huge source of them is sitting right in their closet — and they're not just ending up in the ocean. They're ending up in your body.

Synthetic clothes shed plastic constantly

Fabrics like polyester, nylon, and acrylic are plastic in fiber form. Every time you wear, wash, or dry them, they shed microscopic plastic particles. These fibers are invisible to the naked eye but they go everywhere — into your skin, into the air, and into the water supply.

From your laundry to your lungs

During washing, microplastic fibers pour into wastewater by the hundreds of thousands per load. Water treatment plants can't fully catch them. They flow into rivers and oceans, get eaten by marine life, and work their way up the food chain back to us. Meanwhile, fibers shed while wearing clothes become airborne and are breathed in directly.

What they're doing to your hormones and fertility

This is the part the fashion industry really doesn't want to talk about. Microplastics don't just accumulate — they carry hormone-disrupting chemicals with them, including phthalates and BPA, which leach off the plastic particles once inside the body.

A 2023 study published in Toxicological Sciences found that microplastic exposure significantly disrupted endocrine function and decreased sperm quality in animal subjects. A review published in the American Journal of Men's Health warned that microplastics may be a meaningful contributor to male infertility, citing their presence in every human semen sample tested in recent Chinese research. For women, microplastics have now been found in ovarian follicular fluid, raising questions about their impact on egg quality and ovulation.

Phthalates specifically have been strongly linked to decreased testosterone, irregular menstrual cycles, ovulatory problems, and higher rates of reproductive issues in both men and women. These aren't fringe findings — they're consistent across dozens of independent studies.

Should you be worried?

The honest answer is that large-scale human trials are still catching up. But the evidence is consistent enough that it's worth taking seriously, especially if hormonal health, fertility, or pregnancy is on your radar. Reducing your synthetic fabric exposure is one of the most practical steps you can take to lower your daily chemical load.

The easiest thing you can do

Choose natural fiber clothing. Cotton, linen, hemp, and wool don't shed microplastics. They break down naturally at the end of their life instead of persisting in the environment for centuries. It's one of the most direct ways an individual can meaningfully reduce their plastic exposure.

What about stretch fabrics?

A common concern when switching to natural fibers is losing that comfortable stretch. At NATRL, we use up to 5% spandex in select pieces, just enough for ease of movement and a great fit, while keeping the fabric overwhelmingly natural. It's a meaningful difference from a garment that's 50, 80, or 100% synthetic.
