How should we think about everyday exposure to radiofrequency radiation from cell phones, Wi-Fi, 5G, and other wireless technologies?

In this conversation, I speak with Dr. Devra Davis, epidemiologist and founder of Environmental Health Trust, about her interpretation of the research on wireless radiation, where she believes current safety standards fall short, and practical ways to reduce unnecessary exposure.

We also discuss why questions about children, pregnancy, reproductive health, and long-term exposure remain important areas of research—and where scientific and regulatory opinions continue to differ.

In this episode:

• How exposure from cell phones, Wi-Fi, and newer wireless technologies differs across devices and uses

• Research Dr. Davis considers important when evaluating possible health effects

• Why children and other potentially vulnerable populations receive particular attention in the literature

• Questions around reproductive health, brain health, and long-term exposure

• Practical habits that can reduce radiofrequency exposure without giving up the technologies you depend on

• Nine precautionary steps Dr. Davis recommends

The science around everyday wireless exposure remains debated, and thoughtful experts do not always interpret the evidence the same way. My approach is to understand those disagreements clearly—and then decide which low-cost, low-disruption precautions feel wise.

If you want to reduce everyday exposures at home but aren't sure where to begin, start with the places and products you interact with most often.

In this episode of Practical Nontoxic Living™, I walk through five practical areas that can make a useful starting point:

• Cleaning products

• Cookware

• EMFs and technology habits

• PFAS, or "forever chemicals"

• Everyday choices in the kitchen

For each, I share one simple place to begin—so you don't need to research everything or overhaul your entire home at once.

The goal of Practical Nontoxic Living™ isn't to create a perfectly "nontoxic" home. It's to recognize recurring sources of exposure, understand which changes may be worth prioritizing, and make those changes practical enough to last.

A note on the resource mentioned in this episode: When I recorded this, these five guides were available as my Ultimate Home Detox™ Starter Pack. That resource has since evolved into the free Ultimate Home Detox Kickstart email series, which introduces the foundations of the Practical Nontoxic Living™ framework and helps you begin applying them throughout your home.

Microplastics and nanoplastics have become part of our everyday environment—and researchers are increasingly finding them inside the human body as well.

What we don't yet fully understand is what those exposures mean for our health over a lifetime.

In this episode of Practical Nontoxic Living™, I look at common ways plastics enter our daily routines and share three simple, budget-conscious changes that can reduce unnecessary exposure at home.

In this episode:

• Where microplastics and nanoplastics can come from in everyday life

• What researchers are investigating about their potential effects on human health

• Why reproductive and hormonal effects are receiving scientific attention

• Three practical ways to reduce exposure without trying to eliminate plastic from your life

• How to prioritize the plastic uses that may be easiest and most worthwhile to change

The science around microplastics is evolving quickly. We know exposure is widespread; we're still learning what different particles, doses, and routes of exposure mean for human health.

For me, that uncertainty doesn't require panic—or waiting for every question to be answered. It means looking for simple, low-cost ways to reduce exposures where doing so is practical.

After recording my conversation with Dr. Carmen Messerlian, an environmental and reproductive epidemiologist at the Harvard T.H. Chan School of Public Health, we kept talking—and our conversation turned to sunscreen.

What surprised me was not a new rule about whether sunscreen is "good" or "bad," but how thoughtfully she approaches sun exposure in her own life.

In this short episode of Practical Nontoxic Living™, I share that behind-the-scenes conversation and what it made me reconsider about sunscreen, the UV index, and the many ways we can protect our skin from excessive ultraviolet exposure.

In this episode:

• Why Dr. Messerlian doesn't automatically reach for sunscreen every time she goes outside

• How she uses the UV index to help guide her own decisions

• The role of timing, shade, clothing, hats, and sunscreen in reducing UV exposure

• Why a scientist's personal choices aren't the same thing as a universal health recommendation

• How our conversation changed the way I think about balancing sun protection with concerns about everyday product exposures

We also talk about food, including lycopene-rich tomatoes and other nutrients researchers have studied in relation to skin health. Nutrition may support the skin's normal defenses, but it doesn't replace established sun-protection strategies when UV exposure is high.

For me, this conversation was another reminder that Practical Nontoxic Living™ isn't about replacing one rigid rule with another. It's about understanding the evidence, the tradeoffs, and the context—and then asking: What's wisest here?

What can we influence about eye health beyond prescriptions, glasses, and procedures?

In this conversation, I speak with optometrist and author Dr. Marc Grossman about his integrative approach to vision care—one that considers nutrition, visual habits, stress, the brain-body connection, and complementary practices alongside conventional eye care.

Dr. Grossman draws from optometry, vision therapy, Traditional Chinese Medicine, and decades of clinical experience. Some of the approaches we discuss have stronger scientific support than others, so I think of this episode as an exploration of a broader question: What might support eye health—and where does the evidence become less certain?

In this episode:

• How the eyes and brain work together in vision

• The role nutrition and everyday habits can play in supporting eye health

• How screen use, visual strain, stress, and light exposure may affect how our eyes feel and function

• What vision therapy and eye exercises can—and cannot—be expected to do

• Dr. Grossman's perspective on acupuncture, yoga, and Traditional Chinese Medicine

• Why integrative care should complement, rather than replace, appropriate medical eye care

Your vision is connected to the rest of your biology, but not every eye condition can be changed through lifestyle or complementary therapies. I found this conversation most useful as an invitation to look more closely at the factors we can influence while staying clear about the limits of what we know.

When my daughter asked for a bean bag chair, I did what I often do: paused before clicking "buy."

Bean bags can contain synthetic fabrics, foam fillings, stain-resistant treatments, and other materials I prefer to look at more closely—especially in something that will live in a bedroom or family space and get used often.

In this Raindrop episode of Practical Nontoxic Living™, I walk through how I approached the decision using the same framework I apply to furniture, bedding, rugs, and other textiles throughout the home.

In this episode:

• What I look for when evaluating the fabric and filling in upholstered products

• Why material composition can matter more than marketing words like "natural" or "nontoxic"

• Alternatives such as hemp, kapok, and buckwheat—and the tradeoffs among them

• How my Household Repeat Offenders™ framework helps simplify product research

• How I navigate it when someone in my family loves an option that wouldn't be my first choice

The goal wasn't to find a perfectly "nontoxic" bean bag. It was to understand the materials, decide what mattered most in this particular purchase, and make the wisest choice for our real life.

That small decision is also a good example of what Practical Nontoxic Living™ looks like in practice.

Before Practical Nontoxic Living™ became a framework, it began as a question I couldn't stop asking: What in our everyday environment might be affecting our health—and what can we realistically do about it?

In this foundational episode, I share the story behind A to Z of D-Toxing: The Ultimate Guide to Reducing Our Toxic Exposures—the book I spent eight years researching and writing after becoming a mother and beginning to look more closely at the chemicals, materials, and technologies surrounding my family.

I also talk about how that research changed the way I think about the home: not as something we can make perfectly "nontoxic," but as an environment we interact with every day—and therefore one where informed choices can add up over time.

In this episode:

• What first prompted me to investigate everyday environmental exposures

• Why I spent eight years researching and writing A to Z of D-Toxing

• How chemicals, heavy metals, materials, and technologies became part of my broader understanding of health

• Why the home deserves a place alongside other familiar influences such as diet, exercise, sleep, and stress

• How to begin reducing exposures without trying to change everything at once

• The ideas that eventually became the foundation of Practical Nontoxic Living™

This episode captures an earlier chapter of my work, but the question underneath it is still the one I'm asking today: What is shaping us—and what can we wisely shape in return?

Could something as ordinary as the water you choose make a meaningful difference in your microplastic exposure?

One widely cited analysis estimated that people who get all of their recommended drinking water from bottled water could ingest substantially more microplastic particles from water each year than people who drink tap water.

In this short Raindrop episode of Practical Nontoxic Living™, I look at that finding and why it reinforced my preference for filtered tap water when the local water supply and an appropriate filtration system make that a practical choice.

In this episode:

• What researchers estimated about microplastics in bottled versus tap water

• Why the numbers are estimates—not a precise prediction of anyone's individual exposure

• Why bottled water can be an important source of microplastic exposure

• Why I generally prefer appropriately filtered tap water when practical

• How one repeated everyday choice can reduce an exposure without making life more complicated

Microplastic science is evolving quickly, and estimates vary considerably depending on how particles are measured and what sources are included. But this is a good example of how Practical Nontoxic Living™ works for me: identify a recurring exposure, understand what the evidence can—and can't—tell us, and make the simpler choice when there's little downside.

What happens to measurable chemical exposures when you change the products and habits you interact with every day?

DailyMail Deputy Health Editor Alexa Lardieri wanted to find out.

Before beginning Ruan Living's 40-Day Home Detox, Alexa used Million Marker urine testing to measure several chemicals commonly encountered through consumer products and everyday environments. Her initial results found bisphenol levels 88% higher than the U.S. average.

Then she spent 40 days systematically examining what she bought, used, ate from, cooked with, cleaned with, and brought into her home.

When she tested again, her bisphenols were undetectable.

In this follow-up to Episodes 86–89, Alexa and I look closely at her before-and-after results—not as proof that every change was caused by the program, but as a fascinating real-life example of how quickly some measured exposures can change.

In this episode:

• What Alexa's before-and-after urine testing showed

• How her measured bisphenol exposure went from 88% above the U.S. average to undetectable

• Which products and habits she changed during the 40 days

• What happened to her measurements of benzene-related and other chemical exposures

• Why some phthalate measurements increased again—and what might have contributed

• How travel, personal care products, furnishings, and other everyday circumstances can change exposure from one day to the next

• What biomonitoring can tell us—and what a single urine test cannot

One of the most useful lessons from Alexa's results is that exposure isn't necessarily fixed. For chemicals that leave the body relatively quickly, what we encounter repeatedly can influence what shows up in biomonitoring.

But this is one person's experience, not a controlled experiment. We can't know exactly which individual change produced which result—or assume everyone would see the same pattern.

What Alexa's experience does show is something I find encouraging: some of the exposures we encounter every day are measurable, dynamic, and potentially modifiable.

What should you look for when choosing fabrics for clothing, bedding, towels, rugs, curtains, or upholstered furniture?

In this short Raindrop episode of Practical Nontoxic Living™, I distill the deeper textile discussion from Episode 105 into three practical shopping principles for choosing lower-exposure fabrics and materials.

We look at both fiber choice and certifications, because what a textile is made from is only part of the story. Dyes, finishes, treatments, and manufacturing processes can matter too.

In this episode:

• Why I often prioritize simpler natural fibers such as cotton, linen, and hemp

• What GOTS-certified organic cotton can tell you—and what it doesn't

• How certifications such as OEKO-TEX® MADE IN GREEN can help you evaluate finished textiles

• Why "natural," "organic," and "nontoxic" aren't interchangeable terms

• How to make more informed choices without researching every textile like a chemist

You don't need to replace every fabric in your home. I think it's more useful to pay attention when you're already buying something new—especially items that spend a lot of time against your skin or occupy a large surface area in your home.

This is Practical Nontoxic Living™ in practice: understand the patterns, know which signals are useful, and make the wiser choice when it's practical.
