28. Are Your Workout Clothes Affecting Your Fertility?

In this episode, Sam details a viral video urging people to stop wearing stretchy workout leggings. Between that and HealthTok, there's been a lot of noise lately about the dangers of synthetic materials in our clothes—polyester, nylon, spandex, elastane, and the like. Allegedly, they're endocrine disruptors, and may even contain carcinogens and other harmful chemicals. But is it a concern that actually moves the needle, or just a buzzy conversation designed to sell detoxes and create engagement on social media? As usual, Sam gets to the bottom of it. Listen to this episode if you're in the loop on HealthTok and always worried about a new endocrine disruptor, if you own lots of cute workout sets that are suspiciously stretchy and sweat-wicking, or if you're pursuing lifestyle changes in an effort to conceive.
