Polyester has become a staple in modern wardrobes, valued for its affordability and versatility. However, the hidden costs of wearing this synthetic fabric extend far beyond its low price. Understanding the impact of polyester and other synthetic fabrics on health and the environment is crucial for making informed clothing choices.

Polyester is everywhere. It’s affordable and easy to produce, which is why it’s used in so much of our clothing. But here’s the catch: polyester is essentially plastic. It’s made from toxic chemicals that don’t just disappear when the fabric is woven into clothes. These chemicals can linger, and when worn, polyester can absorb oils and dead skin cells, leading to skin irritation, dryness, and discomfort. Despite its widespread use in sportswear and everyday clothing, polyester’s lack of breathability often makes it less suitable for prolonged wear.

However, it’s not just polyester that raises red flags. Fabrics like acrylic, nylon, and viscose/rayon also have their own set of problems. The production of these materials involves harmful chemicals that can leech into the skin and cause skin irritation or other health problems. Over time, the constant exposure to these chemicals can add up, leading to potential long-term health risks. What’s more, these synthetic fabrics have a huge environmental impact. They’re not biodegradable, meaning they contribute to pollution and waste long after we’ve stopped wearing them.

Switching to natural fibers such as organic cotton, hemp, linen, wool, and silk offers a healthier and more sustainable alternative. These materials are not only gentler on the skin but also have a significantly lower environmental impact. Organic cotton and hemp, in particular, are known for their durability, comfort, and minimal ecological footprint.

Natural fibers are also praised for their unique properties, including breathability and the ability to regulate body temperature. Some studies even suggest that linen, may have beneficial vibrational and cellular regeneration properties that can positively influence health and mood. This means that clothing isn’t just something to wear, but its something that can influence how you feel. Wearing organic cotton or hemp underwear can support better hormone health and overall well-being.

Investing in high-quality, organic fabrics for everyday items like sheets and clothing can lead to long-term cost savings and improved well-being. By opting for natural fibers and avoiding toxic synthetic fabrics, it is possible to protect both the body and the planet, making clothing choices that are healthier and more sustainable.

If you’re thinking about making the switch, I highly recommend doing some research and starting with the basics—like swapping out your polyester sheets for organic cotton or trying out hemp or linen clothing. Trust me, your skin will thank you, and you’ll feel better knowing you’re making healthier choices for yourself and the planet.

Q&A

• What are the concerns regarding dyes and chemicals used in clothing (even if natural)?

  Toxic chemicals in dyes and fabric treatments may be harmful if absorbed by the body. Azo-free labeling is a good sign, as it indicates that the dyes used do not contain azo compounds, which can release harmful amines. However, this doesn’t necessarily mean the garment is free from all toxins. For broader assurances of sustainability and safety, looking for certifications like GOTS is a wise move, as they cover a range of criteria, including chemical use, environmental impact, and social responsibility. Another option is to opt for clothing manufactured in highly developed countries or regions with strict chemical regulations, like the EU.

• Is bamboo fabric a good option for sustainable clothing?

  While bamboo is often marketed as an eco-friendly option, not all bamboo fabrics are created equally, and some may involve harmful processing methods. It's important to research the production process of bamboo fabrics before considering them sustainable. Bamboo rayon (mentioned in this episode), undergoes a chemically-intensive process to turn bamboo pulp into fiber. Bamboo lyocell, on the other hand, is produced using a closed-loop process similar to Tencel, making it a more eco-friendly option.

• What are plant based polyamides, and are they safe?

  These fabrics are indeed interesting because they are often marketed as biodegradable alternatives to traditional synthetics. While they are derived from renewable resources (like Bamboo), there are still some concerns about the chemical processes involved, particularly the use of solvents and the potential for residual toxicity. It’s a developing area, so I would recommend doing thorough research on the specific brand or product.

• What are alternative materials to synthetic fabrics like spandex?

  Spandex, a polyurethane-based material, can be problematic for those concerned about fabric toxicity. Sorona, a corn-based fiber, as a safer alternative. Additionally, looking for elastic fully encased in natural fabric can reduce direct skin contact with synthetic materials.

• What can be done to avoid toxic materials in second-hand clothing?

  Second-hand shopping is a good option for sustainability, but it's essential to be cautious about the brands and materials of the items purchased. Avoid ultra-cheap brands like Shein, which have been reported to contain harmful substances.

• Are there safe, natural dyes available for clothing?

  Yes, natural dyes made from plants and mushrooms are available, but they are usually produced by artisans and can be expensive. Another option is to buy undyed organic clothing and dye it yourself, which can be a fun and rewarding way to ensure the safety of the dyes used.

• What steps can consumers take to hold clothing manufacturers accountable?

  Informed consumers can play a crucial role by demanding transparency and safer practices from clothing manufacturers. By supporting brands that prioritize non-toxic materials and holding others accountable, consumers can influence the industry towards better standards. You vote with your purchases and attention!
