The Health Risks of Synthetic Materials in Workout and Wellness Practices

Tharie Designhouse | 2024

A recent research (2024) by the University of Birmingham highlights significant health concerns associated with using synthetic materials, particularly in activities like workouts and wellness practices. These risks go beyond environmental harm, directly impacting the human body through prolonged exposure to materials commonly found in synthetic workout gear and wellness products.

Synthetic Fibers and Skin Absorption

This pivotal study by the University of Birmingham found that synthetic materials, including microplastics and "forever chemicals" like perfluoroalkyl substances (PFAS), can be absorbed through the skin. These substances, present in many synthetic textiles, are linked to hormonal imbalances, immune system disruptions, and long-term toxicity. The study used advanced 3D skin models to demonstrate that toxic chemicals embedded in synthetic fibers can penetrate human skin, underscoring the importance of avoiding direct contact with such materials during physical activity when skin is more vulnerable due to sweating and increased absorption.

Health Impacts of Microplastics

Microplastics, tiny particles shed by synthetic fibers during wear, pose another significant threat. These particles can enter the body through dermal absorption or inhalation when textiles release fibers into the air. Once in the body, microplastics can cause inflammation, oxidative stress, and even disrupt cellular functions, as reported in multiple studies. For people engaged in physical activities like yoga or intense exercise, exposure risk increases due to prolonged skin contact and elevated body temperatures

Sweat and Synthetic Clothing: A Risky Combination

Synthetic workout gear, often praised for its durability and moisture-wicking properties, can exacerbate these health risks. When synthetic fibers like polyester and nylon come into contact with sweat, they may release more chemicals, including dyes and processing agents. These substances can irritate the skin and have been associated with allergic reactions and conditions like dermatitis.

Additionally, trapped moisture in synthetic materials creates an ideal environment for bacteria and fungi, leading to unpleasant odors and potential skin infections. Cotton or organic bamboo alternatives offer better breathability and lower chemical exposure, making them safer options.

Hormonal Disruption and Chronic Exposure

PFAS, a group of chemicals often used in waterproof and stain-resistant coatings on synthetic gear, are particularly concerning. Known as "forever chemicals," PFAS are persistent in the environment and the human body. Chronic exposure to these substances has been linked to reproductive health issues, thyroid dysfunction, and even certain cancers. The Birmingham study emphasizes the need to limit contact with these materials, particularly during activities that involve prolonged wear.
