Polyester, the most widely produced synthetic fiber globally, is facing increased scrutiny regarding its potential health and environmental impacts. Social media trends show a growing movement of consumers opting for natural fibers and questioning the widespread use of polyester.
Concerns have emerged linking polyester to serious health issues such as cancer and fertility problems. Professor Mohamed Abdallah from the University of Birmingham is addressing these claims, breaking down the scientific evidence. Alongside this, Chelsea Coates from the What in the World team is providing guidance on making more informed clothing choices to mitigate potential risks.
The BBC Sounds podcast "What in the World" released an episode titled "Why polyester is in its flop era" on October 20, 2026, which explored these issues. The 10-minute episode, presented by Hannah Gelbart, featured insights from Professor Abdallah and producer Chelsea Coates, with contributions from producer Emily Horler and editor Verity Wilde. It also touched upon the environmental implications of polyester production and disposal.
Polyester's prevalence in everyday clothing, from shirts to more complex garments, means its impact is far-reaching. The synthetic material is derived from petroleum and its production is energy-intensive. While it offers durability and affordability, the potential long-term consequences for human health and the planet are increasingly becoming a focal point for both consumers and environmental advocates.
