Wellness, Actually with Emily Oster & Perry Wilson, MD

This week, Emily, a woman, and Perry, a man, wade into the complicated world of hormone replacement therapy, the first of a two-part series on exogenous hormones and the sexes who love them. What do hormones do for women, and what happens when they recede? And why was HRT so closely -- and erroneously -- linked to breast cancer? Plus: a new type of diabetes, a normie CDC nominee, and the reclassification of psychedelics. Submit a question for our weekly mailbag at wellnessactually.fm.

This week, Emily and Perry discuss continuous glucose monitors -- a gamechanger for diabetics and just kind of an overabundance of information for everyone else. What does glucose do to the body and what's the value of tracking it, along with everything we eat? Should we be using this data to regulate our intake? And what are the risks of knowing so much? Plus: rising and falling birthrates, Jay Bhattacharya's politicized Covid vaccine report, and welcoming folate into our corn tortillas. Registration link for Emily's interview with Jay Bhattacharya.

This week, Emily and Perry explore the vast array of protein vehicles that's taken over our influencer culture and supermarket aisles. How much protein are we told we need, and what's the over/under on how much we really need? What does protein do for our bodies anyway? And given the protein bars and protein water and protein Pop Tarts available (protein is having a moment, you guys), is it possible to have too much? Plus: GLP-1s all over the news cycle, the rising use of gas station kratom, and, ladies and gentlemen, the American Contact Dermatitis Society presents our 2026 Allergen of the Year.

This week, Emily and Perry tackle creatine, a beloved amino acid derivative with surprisingly robust health properties. What is it actually doing to our muscles, and our brain? Pop a gummy, or stir in some powder, and find out. Plus: Casey Means might be out for Surgeon General, stem cells don't help heart attacks, and just how much sugar intake affects your kids.

This week, Emily and Perry go toe-to-toe with the scammier side of the wellness industry: regenerative medicine clinics that claim to inject you with stem cells. Are they the fountain of youth? (No.) Are they even injecting you with stem cells? (Not really.) Are they preying on sick people? (Most definitely yes.) From knee cartilage to sickle cell disease, we've got the miraculous, the bad, and the truly ugly of stem cell therapy. Plus: the generational woes of lead poisoning, debunking stress as a cause of cancer, and doulas for all! Submit a question for our weekly mailbag at wellnessactually.fm.

This week, Emily and Perry dive into the here, there, and everywhere of microplastics. We know they're in the air we breathe and the water we drink, but how bad are they for us, really? How do our bodies respond to them, and how long do they even stay inside us? And can they be avoided? Plus: Leucovorin approved to treat autism, whether ChatGPT is a trustworthy triage nurse, and curious reports of painful sex in college students.

This week, Emily and Perry shine a light on red light therapy: its origins, its heroic use of the mighty mitochondria, and the supposed countless benefits (better mood, wound healing, facial rejuvenation, hair regrowth? You betcha!) of sitting in front of a hot red light that may or may not even be able to penetrate your skin. Plus: the disturbing return of polio, whether multivitamins have an effect on epigenetic aging, and if the pitch clock, while modestly good for Emily's enjoyment of baseball, is ruining pitchers' shoulders.

This week, Emily and Perry discuss GLP-1s, those blockbuster weight-loss drugs that have taken the world by storm -- and not just what you already know about them. From the origins in Gila monster venom to the surprisingly long history of their use, they explore their effectiveness, side effects, lingering questions about long-term usage, and the weird knock-on effects in both the brain (libido?) and our society (protein water?). These drugs are here to stay, so let's understand them from every angle. Plus: RFK vs. Dr. Mike, a concerning Surgeon General pick, and unsurprising data around football head injuries.

This week, Emily and Perry plunge, as it were, into the temperature extremes: cold plunges and saunas. Is there any actual value to shocking your body with ice water or sweating out an ocean? Or are we just gluttons for punishment? Plus: soaring measles rates, Jay Bhattacharya's double federal appointment, and pandemics lurking under the ice.

This week, Emily and Perry tackle peptides, the purported panacea for all health ailments. Can an injection of these tiny bits of protein actually boost your metabolism, plump up your skin, heal your injuries, and overall prolong your life? And what could possibly go wrong when you inject a peptide stack of dubious origin anyway? Plus: mRNA flu vaccines, hormone replacement therapy, and the optimal time to hoard condoms at the Olympic Village (wink wink). Submit a question for our weekly mailbag at wellnessactually.fm.

In our inaugural episode, Emily and Perry talk all things sperm: if it's on the decline, how to juice its quality, the perils of tight underwear, and what a high sperm count says about your manliness (spoiler: absolutely nothing). Plus, vitamin K shots at birth, the keto diet to treat schizophrenia, and, in honor of the Olympics, whether penis pumping helps your air time.

GLP-1s. Colostrum. Microplastics. Red light therapy. Vaccines. There’s a staggering amount of health and wellness news and information, and it’s bombarding us everywhere we look. Who’s got time to parse it out, to verify it, and then to actually do the work of improving our health? And what if those wellness influencers actually knew how to read a medical study? That’s why we’re here. We are Emily Oster, best-selling author and data expert, and Perry Wilson, a medical doctor. And our goal is to separate fact from fiction, causality from correlation, so that you can stay informed without being overwhelmed. Every episode, we cover the health news of the week, take listener questions, and do a deep dive into a buzzy and misunderstood wellness topic so that you can actually make the best decisions for your own health. So join us for a weekly dose of sanity. It might actually be just what the doctor, and the economist, ordered: health advice for real life. See omnystudio.com/listener for privacy information.

For many people, when we start thinking about a family, we assume it'll just happen nine months from the moment we start trying. But that isn't the way it happens for all of us. And fertility can often be a journey that's more winding and more complicated and more confusing than we expected it to be. That's why ParentData has launched a new content vertical, Trying to Conceive (TTC), covering everything from ovulation windows to donor eggs to infertility treatments, along with a newsletter all about infertility treatment in particular, which aims to answer all of your questions with data. It's our mission to provide real evidence-based information so you can make the best decisions for your family. Today on ParentData, we're airing the audio from an event Emily did with three of the people who have contributed most to our new initiative: Dr. Breonna Slocum, a reproductive endocrinologist and fertility specialist, Marea Goodman, a licensed midwife and author, and Dr. Pooja Lakshmin, a perinatal psychiatrist. This roundtable of experts discuss about where to start with fertility, answer audience questions in real time, and consider what they all wish that they knew before starting the journey of trying to conceive.

When you look at the data, it is true that after people have kids, marital satisfaction declines. Having a baby drastically changes everything in your partnership that was familiar, that was predictable, that you got used to. And some of those are the reasons you got into the relationship in the first place. That’s the reality of having kids. And as much as we love them, it can be an incredible shock to the system. There were date nights, there were lazy Sunday mornings in bed, and now there are feedings and diaper changes, feeling touched-out, packing school lunches the night before or at 5:45 in the morning. To paraphrase Ethan Hawke’s character from Before Sunset: We used to be in love. Now we’re roommates who run a day care together. Today on ParentData, we're joined by Dr. Yael Schonbrun, a clinical psychologist, an author, and a researcher who focuses on the science and data behind healthier, happier relationships. And she’s here to help you baby-proof your relationship. Take heart: for many — probably most — couples, this issue is not hopeless.

Shots are never a fun experience. Even if you are enthusiastic about vaccines, holding your kids as they get them is not usually a high point of parenting. And right now, the conversation about vaccines is increasingly fraught - and not just because our kids are sometimes afraid of needles. Because we're living in a moment where vaccines, long one of the most trusted and studied preventative medical treatments in existence, are suddenly being viewed with skepticism. Debunked theories about the relationship between vaccines and autism, for example, are taking center stage on Instagram and Facebook, but also in congressional hearings. Part of the problem is a lack of understanding. People don't know quite how vaccines work or why there are more now than in the past or how we can know that they are safe. Today on ParentData, we welcome Dr. Adam Davis. Adam is a pediatrician in the Bay Area, and he has a lot to say about vaccines from the perspective of someone who gives them. In the conversation, we talk about our theories on why the COVID vaccine sped up a slow-growing movement around vaccine skepticism, about the role that vaccines play in public health, about what it’s like for doctors to deal with vaccine skeptics in their own practice and what people can and can't be talked into or out of, and, because it’s a parenting podcast, some hacks for getting your kids through vaccines without too much drama.

In the last month, we've aired podcast conversations with Dr. Nathan Fox and Dr. Bapu Jena, and though the content is different, there’s an underlying thread that connects them both: what it means to deal with risk, and uncertainty. And not lose your mind. Economists deal with this constantly, and so do parents, but not in the same way. Economists learn not to panic in ways that parents, understandably, have a really hard time with. We’re trained to read the studies, and spot their holes, or their aims and impacts. Yes, we live in a world with trace amounts of lead in Cheerios, and sometimes it can feel scary to leave the house. But things that are low risk are low risk, no matter how scary they feel. Today on ParentData, Emily reads her recent article on risk and uncertainty aloud, and encourages us all to think about risk like economists, so that we can internalize it as sane parents.

For many of us, our first exposure to our pelvic floors is through the Kegel exercises we learned about in Cosmo, promising us great sex. The reality of our pelvic floors comes roaring back in pregnancy, when they are are more taxed than they've ever been. The pelvic floor turns out to have a hand in many things, including peeing, pooping, sex, pregnancy, labor, birth, postpartum, and menopause. And like with all muscles, the more we take care of them, they better they can take care of us. Today on ParentData, we welcome the Vagina Whisperer herself, Dr. Sara Reardon. Sara's new book, Floored: A Woman’s Guide to Pelvic Floor Health at Every Age and Stage, which will be released in June, explores the seasons of life with a pelvic floor, from puberty to menopause. In this conversation, we talk about the optimal ways to pee and poop. We discuss what actually happens when you go to pelvic floor therapy. We discuss Kegels and why they are often good but also not a panacea. More than anything, Sara takes something that we all experience privately, and encourages us to shine a light on it, take the stigma away, and tighten up with confidence.

Today on ParentData, we're welcoming back Dr. Nathan Fox, Emily's co-author for The Unexpected- a book about when things go wrong, or at least get complicated, in a pregnancy. Nate is an OB-GYN and a maternal-fetal medicine specialist, and he is one of our favorite returning podcast guests, not just because he’s a great talker but also because it’s really nice to have a doctor who can both provide medical answers to questions that come up around pregnancy, and help you have the best possible experiences with your own doctor. We’re discuss some big issues that arise during pregnancy and the many prenatal doctor’s visits; about the distinction between self-management and calling your doctor (when do you know if something is normal-bad or bad-bad?), and we’ll talk about just how subjective that line actually is. We also talk about risks and tradeoffs and about the kinds of postpartum issues that are worth addressing while still pregnant (we're looking at you, depression and anxiety). The Unexpected, and this conversation, are meant to help people be much better prepared for what they may face in their pregnancies and to help better navigate conversations with doctors — both the expected conversations and the unexpected ones.
