On the 17th (local time), CNN in the United States reported the results of an analysis conducted by the California-based nonprofit organization Center for Environmental Health (CEH) on bisphenol A (BPA) contained in sportswear over six months starting from October last year. BPA was detected at levels up to 40 times the safety limit in products from eight brands including Nike, Adidas, Patagonia, Champion, and Athleta.

The BPA standard in California is 3 micrograms (㎍), but leggings, shorts, sports bras, and workout shirts sold by these brands contained BPA amounts exceeding California's standard.

BPA is a representative environmental hormone that stimulates the secretion of female hormones. It is particularly harmful to women, causing issues such as dysmenorrhea (menstrual pain), menorrhagia (excessive menstruation), and if excessively exposed during pregnancy, it can cause problems in the development of the fetus's reproductive system.

It is also known to be associated with cancer, cardiovascular diseases, obesity, and asthma. BPA is commonly detected in many everyday products such as receipts, water bottles, toys, and flooring materials.

In this investigation, BPA was detected only in 'polyester' clothing containing 'spandex'.

In previous tests, BPA was detected at 22 times the safety standard in sports bra products from brands such as Asics and The North Face.

CEH stated, “Since sports bras and workout clothes are usually worn for several hours and cause a lot of sweating, BPA can enter the bloodstream through the skin within seconds to minutes, potentially leading to higher BPA exposure than usual in daily life,” and advised, “Consumers should minimize BPA exposure time by changing clothes immediately after exercising.”
