A New Chapter · Begins September 8
The Practical Nontoxic Living™ Podcast
Conversations with Sophia Ruan Gushée about the science, choices, and stories that shape a healthier, happier future.
The first 135 episodes explored what enters our homes. The next chapter widens the lens outwards and deepens the lens inward.
For twenty years I’ve helped people clear the toxicants out of their homes. But the deeper detox, I’ve come to realize, is the one we do on the inside—the inherited beliefs, assumptions, outside messaging, and self-talk that limit our life experience.
This season I’m stretching that thread. I’ll continue sitting with pioneering scientists, physicians, authors, and entrepreneurs, but I’ll explore toxicity and healing even more creatively and introspectively.
The more I learn, the more I see how much there is to learn. Come figure it out with me.

One Practice, A Sharper Lens
We first learned to question what enters our homes. Now we’re learning to question what lives in our minds.
One question
shapes every episode.
Does this conversation help you see something differently—and trust yourself more?
Every conversation is a chance to see more clearly—to question what we’ve been handed, weigh it thoughtfully, and choose what belongs in our homes, our minds, and our lives.
It’s the same practice that started Ruan Living—now explored more broadly.
In This Chapter
The threads we’re following.
From the exposures in your home to the stories in your head—and the science that helps us think clearly about both.
The Body
How our biology responds to the world around us—and what science reveals about the connection.
The Home
More than four walls. Home is an ecosystem of body, home, and planet. We'll explore the invisible ways each shapes the others, and practical ways to take care of both.
The Self
How we feel about and see ourselves—and why. The assumptions and self-talk we absorbed without consciously choosing, and the slow work of deciding what to keep.
The conversations ahead.
Scientists. Physicians. Entrepreneurs. Artists. Thinkers.
Each brings a different lens to the questions we're learning to navigate together. Here's a first look at the conversations ahead.
What does the science say about cell phone radiation and brain cancer?
David O. Carpenter, MD
Founding Director, Institute for Health and the Environment
How do we make thoughtful decisions with conflicting evidence and expert opinions?
What does the evidence suggest about fertility and environmental exposures?
Carmen Messerlian, PhD
Harvard Environmental Reproductive Epidemiologist
What does a precautionary approach look like in everyday life?
Why is ADHD so often overlooked in bright, high-achieving girls?
Ellen B. Littman, PhD
Clinical Psychologist & Co-author of Understanding Girls with ADHD
How does ADHD present differently in girls and women? What strengths often accompany it? And how can understanding it lead to greater self-awareness, healthier habits, and compassion?

How do you build a meaningful life without a roadmap?
Cyrus Massoumi
Founder of Zocdoc and Dr. B
Raised by a physician and far from Silicon Valley, Cyrus followed an unlikely path from solving his own earache to founding Zocdoc, a company valued at $1.8 billion that transformed how millions of people find healthcare. A conversation about intuition, resilience, and the courage to pursue a path no one else can see.

What happens when you refuse to allow your circumstances to limit your future?
Hannes Schmid
Legendary Rock and Fashion Photographer & Founder of Smiling Gecko
Born into extreme poverty in a remote mountain community, Hannes went on to photograph Queen, The Rolling Stones, AC/DC, Bob Marley, and more than 250 musical artists before leaving it all behind to found Smiling Gecko. A conversation about adventure, reinvention, and the extraordinary possibilities that emerge when you refuse to let your beginnings define your future.
What does it feel like when the next healthier decision becomes easier than the last?

A new chapter.
The same mission.
For more than a decade, this podcast explored what our homes, our products, and our everyday choices bring into our bodies—the toxic exposures we live with, and what the science does and doesn’t yet show. Those 135 episodes remain an essential part of Practical Nontoxic Living—where thousands of listeners first explored PFAS, plastics, pesticides, EMFs, indoor air quality, fertility, and practical ways to reduce toxic exposures.
Those conversations continue.
But the questions are getting bigger. And deeper.
This next chapter expands that work while asking: what else shapes our health, fulfillment, choices, and the futures we create? We'll continue questioning what enters our homes—and what enters and resides in our minds. Not because the earlier work is finished, but because it pointed here.
Chapter One
Understanding the world around us.
135 episodes on toxic exposures, health, wellbeing, and Practical Nontoxic Living.
Chapter Two
Understanding ourselves.
Building on everything we’ve learned about the world around us, we begin asking bigger questions—about how we question, unlearn, trust, and choose how we live—to optimize factors that support our healthspan and longevity.
One practice runs through both: discernment.
The foundation.

From the Podcast
Trusted experts, in their own words.
“Even very low doses of some of these chemicals can have profound effects, especially in the developing fetus.”
“We know we can make a real difference in our exposure through the diet.”
“So to the extent that the environment can also stress you, it can contribute to making you sick. And to the extent that we can control our environment, we can design the environment to optimize health, to reduce stress, to actually enhance the positive.”
“The human body is a wonderful thing. We have lots of ways to repair damage.”
