Forever Chemicals in Everyday Living

“Forever chemicals,” known scientifically as PFAS (per- and polyfluoroalkyl substances), are increasingly recognised as a hidden health concern in modern homes. These chemicals are called “forever” because they do not break down easily in the environment or the human body, meaning exposure can accumulate over time.

According to the National Health and Medical Research Council, PFAS are widely used in products such as non-stick cookware, stain-resistant fabrics, carpets and water-repellent clothing. They are also found in drinking water, personal care products and even some sleepwear.

In the home, for example, that convenient non-stick surface or spill-proof fabric may come at a cost, with research linking PFAS exposure to hormone disruption, altered immune and thyroid function, liver disease, lipid and insulin dysregulation, kidney disease, adverse reproductive and developmental outcomes and cancer.

Australian authorities recommend a precautionary approach and minimising exposure where possible. In the kitchen, consider replacing non-stick cookware with safer alternatives such as cast iron, stainless steel, or high-quality ceramic.

Drinking water is another important consideration, and using a high-quality water filtration system, such as reverse osmosis filters, is recommended.

For sleepwear and clothing, choose organic cotton, linen, or bamboo fabrics that are breathable and free from chemical treatments. Avoid items labelled “stain-resistant” or “wrinkle-free”, as these often rely on PFAS-based coatings.

Soft furnishings, like carpets, curtains, and lounges are best made from natural fibres such as wool, cotton, or hemp, without added stain protection. Reducing plastic use—particularly in food storage—can also help, with glass and stainless-steel offering safer alternatives.

Finally, take a closer look at personal care products. Choose simple, low-tox options with minimal ingredients, and avoid products marketed as long-lasting, waterproof, or stain-resistant, as these may also contain PFAS.

Creating a healthier home does not require perfection—just informed choices. By gradually replacing high-risk items, you can meaningfully reduce your exposure and support a safer indoor environment for your family.
