Yoga pants and microplastics
A recent scientific study has found that some people have up to a crayon’s worth of plastic in their brains. How is it getting there? A 2023 research revealed that human sweat can extract poisonous chemical substances from microplastics, doubtlessly making them accessible for absorption via the pores and skin. This discovery raises severe considerations concerning the artificial supplies we put on day-after-day like yoga pants and artificial underwear.
Researchers on the University of Birmingham examined widespread plastic microfibers in a lab utilizing artificial sweat. Their findings, revealed in Environmental Science and Technology, confirmed that brominated flame retardants—chemical substances generally used to boost plastic efficiency—leached out of the microplastics upon contact with sweat. These chemical substances, previously linked to neurotoxicity, reproductive harm, and cancer in animal studies, might now pose direct dangers to human well being.
Polyethylene microplastics have been discovered to launch the best ranges of those poisonous components. Alarmingly, our pores and skin is in fixed contact with microplastics—not solely from clothes but additionally from mud, plastic aligners for our teeth, cosmetics, and even the air we breathe.

Dr. Mohamed Abdallah, a lead researcher on the research, emphasised that human sweat accommodates oily parts that speed up the leaching course of, making these chemical substances extra available for pores and skin absorption. With microplastics already widespread in our surroundings, the clothes we select issues greater than ever.
“Because poisonous flame-retardant chemical substances are hydrophobic, it wasn’t clear if they might leach out of the microplastic to human sweat. However, human sweat is a posh combination that accommodates oily parts referred to as sebum, which facilitated the leaching of poisonous chemical substances from microplastics, rendering them accessible for absorption via the pores and skin.
“With this new proof, coverage makers want to noticeably think about the dangers of microplastics and human contact with them frequently. We will likely be persevering with to analysis how these chemical substances that may be leached via contact with sweat could also be absorbed by human pores and skin each day.”
Fast Fashion’s Hidden Risk
Sweaters by Babaa use actual, pure wool for a sweater than received’t shed microplastics to the atmosphere or your physique. We personal this sweater and put on it on a regular basis.
Synthetic clothes, usually comprised of polyester, nylon, and acrylic, sheds microplastics with each wash and put on. Now, proof means that these plastic fibers could possibly be releasing dangerous chemical substances immediately onto our pores and skin—particularly after we sweat.
The research additionally discovered that antiperspirants and basis elevated the bioaccessibility of sure poisonous chemical substances, making it even simpler for them to enter the physique. Smaller microplastic particles (0.45mm) doubled the speed at which these chemical substances leached out in comparison with bigger particles (4mm), suggesting that extended publicity to plastic-based materials might worsen the dangers.

Natural fibers like natural cotton for clothes and bedding, hemp, and wood-based materials equivalent to Tencel and modal provide a safer, breathable different to artificial supplies. These materials don’t shed microplastics, don’t include poisonous flame retardants, and permit your pores and skin to breathe with out the danger of chemical publicity.
As proof grows concerning the risks of microplastic publicity, it’s time to rethink the materials we put on day by day. Choosing pure fibers isn’t simply an eco-friendly resolution—it’s a selection for higher well being.
