Why Our Clothing Shapes More Than Our Style

Last week, we explored the invisible chemicals shaping our health, particularly endocrine disruptors woven into modern life through plastics and packaging, as well as many other everyday items. But there is another layer of environmental exposure that sits even closer to the body: clothing.

Few materials interact with our bodies as consistently as the fabrics we wear. They touch our skin throughout the day, absorb moisture and heat, and move with us through work, rest, exercise, and sleep. And yet the lifecycle of clothing — how fibers are grown, processed, dyed, worn, and eventually discarded — is something most of us were never taught to think about.

Once you begin to look at it, though, clothing reveals a much larger story. The garments we wear are the result of agricultural systems, industrial chemistry, global supply chains, and environmental ecosystems. And because fabrics remain in constant contact with the body, they also become part of the environment our biology interacts with every day.

Clothing as an Environmental Input

Modern textiles are the product of a surprisingly complex manufacturing process. Fibers are grown or synthesized, spun into yarn, dyed for color, softened for comfort, and often treated with additional chemical finishes that make fabrics wrinkle-resistant, water-repellent, antimicrobial, or stain-resistant.

Each of these steps can introduce compounds that remain within the finished garment.

Conventional cotton may carry residues from pesticides used during cultivation. Some garments are treated with formaldehyde-based resins to prevent wrinkling. Athletic fabrics are sometimes coated with antimicrobial treatments designed to reduce odor. Water-resistant finishes may rely on compounds such as PFAS, sometimes called “forever chemicals” because of their persistence in the environment.

None of this means clothing is inherently unsafe. The human body encounters countless environmental inputs every day and is equipped with detoxification systems that help process them. But textiles represent another layer in the broader conversation we began last week: cumulative exposure.

When fabrics remain in close contact with the skin for long periods, they become part of the environment our bodies respond to.

Skin Is a Living Interface

For many years, skin was described primarily as a protective barrier separating the body from the outside world. Today, we understand that it functions more like a dynamic interface between the body and its environment.

Skin regulates temperature, hosts a complex microbiome, and can absorb certain compounds under the right conditions. This is why topical medications work, why nicotine and hormone patches deliver drugs through the skin, and why cosmetic ingredients can enter systemic circulation.

Clothing interacts with that same surface.

Consider the environments where fabrics meet skin most intensely: long workouts, warm weather, humid climates, sleep, or extended travel. Heat, moisture, and friction all increase interaction between textiles and skin. Fabrics trap heat, absorb sweat, and remain in contact with the body for hours at a time.

This doesn’t mean every garment poses a health concern. It simply reinforces an important idea: the materials we wear regularly are part of our everyday environmental exposure.

The Rise of Synthetic Fibers

For most of human history, clothing was made from natural materials like cotton, linen, wool, and silk. These fibers were biodegradable, breathable, and closely connected to agricultural systems.

The twentieth century introduced a major shift. Synthetic fibers such as polyester, nylon, acrylic, and spandex allowed clothing to be produced quickly, cheaply, and on a massive scale. Today, polyester alone accounts for more than half of all textile fibers produced worldwide.

Synthetic fabrics are derived from petrochemicals and behave differently from natural fibers. They tend to trap heat, retain odor, and shed microscopic fibers when worn and washed. These fibers, known as microplastics, have now been detected in oceans, soil, drinking water, and even human tissue.

Researchers are still working to understand the full implications of microplastic exposure, but their presence highlights an important reality: materials rarely remain confined to their original use. They move through ecosystems.

Clothing is part of that movement.

Where Fabric Begins: The Soil

While synthetic fabrics originate from fossil fuels, natural fibers begin in soil. Cotton, linen, hemp, and wool all emerge from agricultural systems that shape the health of land, water, and ecosystems.

For much of the past century, many agricultural systems have relied heavily on chemical inputs designed to maximize yield. Conventional cotton, for example, is one of the most pesticide-intensive crops in global agriculture. These chemicals affect soil biology, water systems, and surrounding communities.

In response, a growing number of farms are turning toward regenerative agriculture, an approach that focuses on rebuilding soil health, increasing biodiversity, improving water retention, and restoring ecological balance.

Regenerative farming practices such as crop rotation, composting, reduced chemical inputs, and soil-covering plants help replenish soil nutrients rather than deplete them. Over time, healthy soil becomes more resilient, capable of storing carbon and supporting richer ecosystems.

When fibers are grown within these systems, clothing becomes connected to something restorative rather than extractive. The fabric doesn’t just come from the earth; it helps the earth heal.

Circularity and the Future of Fashion

Another part of the clothing lifecycle that often goes unnoticed is what happens to garments after they leave our closets.

Over the past two decades, the rise of fast fashion has dramatically accelerated production cycles. Clothing is designed to be inexpensive, trend-driven, and quickly replaced. Globally, millions of tons of textiles are discarded every year, many of them ending up in landfills where synthetic fabrics can persist for decades or longer.

Circular fashion attempts to rethink this system. Instead of designing garments for short-term use, circular models prioritize durability, repairability, recyclability, and biodegradable materials.

Natural fibers play an important role here because they can eventually return to biological systems. Synthetic fabrics, by contrast, remain within industrial cycles that are far more difficult to close.

When consumers choose higher-quality garments, care for them well, and wear them repeatedly, they participate in this broader shift toward circularity.

Clothing as a Daily Input

When we zoom out, clothing becomes part of the same framework we’ve been exploring throughout this newsletter: the environments we live within shape our biology.

The air we breathe.
The water we drink.
The food we eat.
And the fabrics we wear.

These are not isolated choices. They are layers of input that our bodies interpret continuously.

For many people, the most practical place to begin is with garments that stay closest to the skin: underwear, sleepwear, activewear, and everyday basics. These pieces interact with the body for the longest periods of time and therefore represent the most meaningful opportunities for change.

Gradual upgrades toward natural fibers like organic cotton, linen, or wool can quietly reduce both environmental impact and personal exposure over time.

A Broader Perspective

Understanding the lifecycle of clothing invites us to see garments differently. They are not just aesthetic choices or seasonal trends. They are the result of agricultural systems, chemical processes, manufacturing economies, and environmental ecosystems.

And once they reach us, they become part of the environments we inhabit every day.

When we begin to look at clothing through this lens, our decisions become more intentional. We gravitate toward fabrics that breathe, materials that age well, and garments designed to last longer than a season.

The goal is not perfection.

It is participation in a system that is gradually becoming more thoughtful and, increasingly, more regenerative.
