Polyester is everywhere – from the clothes we wear to the sheets we sleep on. But have you ever wondered if this popular fabric is bad for your health? In recent years, concerns about polyester’s impact on skin and the environment have been growing. In this post, we’ll explore the risks associated with polyester and why it’s important to make informed choices for both your health and the planet.
Polyester is a synthetic fabric made from petroleum-based products. It's created through a chemical reaction between two key ingredients: ethylene glycol and terephthalic acid. This reaction forms a polymer known as polyethylene terephthalate (PET), which is commonly used in textiles. PET fibers are what give polyester its strength and flexibility, making it suitable for a wide range of applications.
Here’s a simple breakdown of the process:
Petroleum-based raw materials: Ethylene glycol + Terephthalic acid
Polymerization: These chemicals react to form PET
Fiber formation: The PET is spun into fibers used for fabric production
The resulting polyester fabric is durable, resistant to wrinkles, and moisture-wicking. It's used in everything from clothing to home textiles like pillowcases, bed sheets, and even high-quality silk hairbands.
Polyester is incredibly popular for a few key reasons. Let's take a look at some of its main benefits:
Durability: Polyester is resistant to wear and tear, making it long-lasting.
Wrinkle resistance: It holds its shape well, even after washing.
Moisture-wicking: Polyester pulls moisture away from the skin, making it a popular choice for activewear and loungewear.
Affordability: It's a low-cost material, which is why it's often used in fast fashion.
These benefits make polyester the go-to fabric in many industries, including fashion, home textiles, and even technical applications. It’s especially used in items like pajamas and exfoliating gloves, where comfort and practicality are key.
Polyester’s affordability and versatility make it a dominant fabric in the textile industry, particularly for businesses looking for cost-effective solutions in mass production.
Low production cost: Easy to produce in large quantities.
Versatile: Suitable for a variety of textile products.
Quick drying: Makes it ideal for items that need to dry fast after washing.
Polyester continues to thrive in the textile industry, thanks to its cost-effectiveness and ability to withstand the demands of modern consumers.
Polyester is known for trapping heat and moisture against the skin, which can lead to irritation. This lack of breathability often causes rashes, eczema, or even acne in people with sensitive skin. The fabric doesn't allow your skin to "breathe" as natural fibers like cotton do. For example, if you're wearing a polyester scarf or sleepwear made of polyester, the fabric may cause your skin to become clammy or overheated, leading to discomfort or skin flare-ups.
The moisture-retaining properties of polyester prevent your skin from staying dry, and this can be a breeding ground for bacteria, further irritating sensitive skin. People with conditions like eczema or psoriasis may find that polyester worsens their symptoms.
Studies have shown that synthetic fibers like polyester can cause allergic reactions. Some people develop allergic contact dermatitis when they wear polyester clothing or use bedding made from the fabric. This condition causes itching, redness, and swelling, and it often appears as a rash or irritation where the fabric touches the skin.
Long-term exposure to polyester, especially in combination with the chemical finishes used in the production process, could lead to persistent skin problems. For example, polyester-based products like silk pillowcases or exfoliating gloves may trigger allergic reactions in individuals with sensitive skin, causing the skin to break out or become irritated over time.
Common symptoms: Redness, itching, hives, swelling.
Long-term effects: Skin conditions like eczema may worsen with continued exposure to polyester.
Polyester is not just made from petroleum-based chemicals; it can also contain harmful substances like formaldehyde, antimony, and PFAS. These chemicals are used in the manufacturing process to make the fabric more durable, wrinkle-resistant, and water-repellent. However, they can leach onto the skin, especially in hot or humid conditions, when the fabric is worn for extended periods.
Formaldehyde, for instance, is used to help keep polyester fabrics wrinkle-free, but it’s also a known irritant and carcinogen. Similarly, antimony is used to create polyester fibers and can be absorbed by the skin, potentially leading to lung and heart issues over time. PFAS chemicals, commonly used to make polyester water-resistant, have been linked to hormone disruption and other health concerns.
Key chemicals to watch out for: Formaldehyde, PFAS, and antimony.
Potential health concerns: Hormone disruption, skin irritation, and respiratory problems.
Polyester may not just irritate your skin; it could also affect your hormones. Chemicals like phthalates and PFAS, often found in polyester, are known endocrine disruptors. These chemicals can interfere with the body’s hormone systems, potentially leading to issues like hormone imbalances and reproductive health problems.
PFAS chemicals, used in water-repellent and stain-resistant polyester fabrics, are linked to a variety of health concerns, including developmental delays and hormone disruption. These chemicals don't just stay in the fabric — they can transfer to your skin, especially if you wear polyester clothes or sleep on polyester bedding like pillowcases or sleepwear for extended periods.
Key endocrine disruptors: Phthalates, PFAS.
Potential health issues: Hormonal imbalances, developmental delays.
Polyester’s impact on fertility, especially male fertility, has raised concerns. Studies suggest that polyester fabrics may reduce sperm count and motility in men. The electrostatic properties of polyester can cause an increase in testicular temperature, potentially interfering with sperm production.
For women, the chemicals in polyester, particularly those used to make the fabric water-resistant or stain-resistant, may affect hormone regulation and fertility. Prolonged exposure to polyester, especially in tight-fitting clothing like polyester underwear, could disrupt the body’s natural hormone balance, potentially making it harder to conceive.
Male fertility issues: Reduced sperm count and motility.
Female fertility concerns: Hormonal disruption from chemicals in polyester.
Polyester’s impact on reproductive health is still being studied, but evidence shows it may interfere with the body’s hormone systems, potentially affecting fertility in both men and women.
Wearing polyester over time can have cumulative effects on your health. Although polyester itself is durable and long-lasting, its prolonged exposure can lead to various health issues. As you wear polyester fabrics, you may gradually accumulate chemicals in your body, especially from regular contact with polyester-based products like exfoliating gloves or silk eye masks.
The long-term risks could include:
Skin damage: Continuous wear of polyester fabrics can contribute to chronic skin conditions, including irritation, eczema, or rashes.
Respiratory issues: Polyester fibers, especially when they break down or are heated, can release chemicals into the air, potentially leading to respiratory problems.
Immune system disruption: Ongoing exposure to certain chemicals used in polyester production can affect the immune system, potentially making the body more susceptible to illnesses.
Even though you might not feel the effects right away, the buildup of chemicals over time can contribute to these long-term health risks.
Some of the chemicals used in polyester production have raised concerns about potential cancer risks. For example, antimony and formaldehyde are often found in polyester fabrics. While polyester itself is not classified as a carcinogen, certain chemicals used in its production have been linked to cancer risks.
Antimony: Often used in the polyester manufacturing process, antimony has been identified as a potential carcinogen. Long-term exposure, especially in poorly ventilated spaces, could increase health risks.
Formaldehyde: This chemical is used to make polyester wrinkle-resistant but is also a known irritant and carcinogen. It can leach out of polyester fabrics, leading to skin irritation and respiratory issues over time.
Although the International Agency for Research on Cancer (IARC) has not classified polyester itself as carcinogenic, the chemicals used during its production process may pose a risk when exposed to the body for long periods.
Potential risks: Long-term exposure to antimony and formaldehyde.
Health concerns: Skin irritation, respiratory problems, cancer.
Even if you don’t notice immediate symptoms, the repeated exposure to these chemicals could potentially have long-term effects.
Polyester’s production process is highly energy-intensive, requiring large amounts of energy and water. This contributes to pollution, depletes natural resources, and increases the environmental footprint. Moreover, polyester is not biodegradable, so it stays in landfills for hundreds of years.
Environmental Issues Caused by Polyester:
High energy use: Producing polyester fabric requires significant energy, which leads to higher carbon emissions.
Water pollution: The manufacturing process releases pollutants into nearby water sources.
Landfill accumulation: Since polyester is non-biodegradable, it remains in landfills for a long time, adding to waste management problems.

| Water contamination | Harmful chemicals released into water bodies |
| Non-biodegradability | Long-term landfill accumulation |
Each time you wash a polyester garment, tiny plastic fibers (microplastics) are released into the water. These fibers pass through sewage treatment plants and flow into rivers and oceans, where they pose a serious threat to marine life. Microplastics are small enough to be ingested by marine animals, eventually making their way up the food chain and potentially affecting human health.
Impact of Microplastics:
On aquatic ecosystems: Marine creatures mistake microplastics for food, leading to injury, starvation, or even death.
On human health: Microplastics can enter the human food chain through seafood, causing potential health risks.
Microplastic Pollution Breakdown:
Polyester fabrics release up to 700,000 microfibers per wash cycle.
These microfibers contribute to the 85% of plastic debris found on ocean shores globally.
Recycled polyester has gained attention as a more sustainable option, as it reduces the need for virgin plastic and keeps waste out of landfills. However, it still shares some of the environmental concerns of its non-recycled counterpart. Recycled polyester still contributes to microplastic pollution when washed, and many of the harmful chemicals used in the original polyester fabric remain.
Pros of Recycled Polyester:
Reduces waste: Keeps plastic bottles and other polyester waste out of landfills.
Lessens the need for new plastic: Helps reduce the environmental burden of producing virgin polyester.
Lower carbon footprint: Typically requires less energy to produce than virgin polyester.
Cons of Recycled Polyester:
Microplastic shedding: Recycled polyester still sheds microplastics during washing.
