Dr. Robert Whitfield explains how PFAS and phthalates in artificial turf and heated plastic bottles disrupt hormones, mimicking estrogen and blocking testosterone. Young athletes face particular risk during critical growth periods, with emerging research linking these chemicals to altered sex-hormone levels, cancer, and immune damage.

In my practice personally, I see the effects of the endocrine disruption of these chemicals every day. PFAS are notorious hormone disruptors. They mimic and interfere with your body's natural hormones. Recent studies have shown positive associations between high serum levels of certain PFAS and hormone-receptive cancers. They are linked to liver damage, kidney disease, and impaired immune function. And then we have phthalates. We've I mean, if you've ever listened to me speak about environmental toxicity, you've heard me talk about phthalates, which are the plasticizers used in things like water bottles. So the classic example is you leave a plastic water bottle, you let it overheat, the phthalate leaches out of the plastic water bottle into the water, and you drink the water and affects your phthalate level. And it's an anti-androgen. They disrupt the balance between estrogen and testosterone. In young developing athletes, obviously this is critical as it is, um, in many of us, but very, very important, especially when they're in their, uh, growth ages, um, and they're changing. Now we're seeing studies showing that exposure to these chemicals alters adolescent sex hormones.
