The Latest Science on Microplastics — And What They’re Doing to Your Body | Dr. Shanna Swan - The Dr. Hyman Show

We’re surrounded by plastics and environmental chemicals every day, but only recently have scientists begun to understand how deeply they may be affecting human health. On this episode of The Dr. Hyman Show, I sit down with Dr. Shanna Swan to explore what the latest science reveals about plastics, fertility, hormone health, and the everyday habits that may be shaping our biology more than we realize. Watch the full conversation on YouTube, or listen wherever you get your podcasts. We Examine: • Why scientists are increasingly concerned about declining sperm counts, fertility, and hormone health • What microplastics, phthalates, BPA, and PFAS actually do inside your body • Why heating food in plastic can dramatically increase exposure to endocrine-disrupting chemicals • The practical changes that may help you reduce exposure and support long-term health This conversation isn’t about fear, rather it’s about understanding how everyday exposures shape our health and where small, practical changes can make a meaningful difference. If this episode has left you thinking differently about everyday exposure and you want to learn more, here are a few great places to start: • Watch The Plastic Detox • Explore Dr. Swan’s work through the Action Science Initiative • Visit UnplasticYourLife.com for practical ways to reduce exposure at home View Show Notes From This Episode
