In recent weeks, as many listeners know, I've been exploring ways to challenge false arguments that MCS is a psychological disorder.

I hope you find this episode of The Chemical Sensitivity Podcast helps.

You'll hear me in conversation with Kevin Elliott, Ph.D. He is the Red Cedar Distinguished Professor of Philosophy of Science at Michigan State University in the U.S.

I was delighted to speak with Kevin, learn about his important research — and I am excited to share this episode with you. 

Kevin explains how scientific research practices — from hidden assumptions to “undone science” — have shaped decades of misunderstanding around Multiple Chemical Sensitivity (MCS). 

You'll hear Kevin explore: 

• How his mother's MCS inspired him to spend decades researching the illness
• Why certain kinds of evidence are ignored
• How harmful psychogenic theories persist
• And what needs to change in research frameworks to genuinely support people living with MCS. 

This conversation is forward-looking and grounded in the belief that better science is both possible and urgently needed to support people with MCS.

In the latest episode of The Chemical Sensitivity Podcast, we’re exploring medical invalidation. It's something virtually everyone with Multiple Chemical Sensitivity (MCS) has experienced and it can be devastating.

Researcher Allyson Bontempo, Ph.D. joins Aaron Goodman on the podcast to discuss her work on healthcare invalidation and discusses: 

·       What she calls an “epidemic” of medical invalidation for people with MCS and other illnesses. 

·       The consequences of dismissal by healthcare professionals — how it affects us on a personal and human level.

·       How people with MCS, as we know, support each other largely online.

·       And some strategies for ways we can advocate for ourselves.

The newest episode of The Chemical Sensitivity Podcast is available now! 
   
It's called “Synthetic Food Dyes & MCS.” 

Researcher and psychology professor Rebecca Bevins tells Aaron Goodman how she discovered her son’s extreme reactions to synthetic food dyes — petroleum-based additives linked to anxiety, aggression, and cognitive disruption. 

Their conversation reveals the impacts of everyday chemicals, something people with Multiple Chemical Sensitivity (MCS) are very familiar with. 

Plus, Aaron explores the momentum that could potentially follow the American Medical Association’s recent acknowledgment that fragrance sensitivity can, in some cases, be disabling.

The newest episode of The Chemical Sensitivity Podcast is available now! 
 
 It's called “Chemical Production, Regulation, & MCS."

I’m speaking with Miriam Diamond, Ph.D., an expert in chemical contaminants and a professor at the University of Toronto in Canada.

You'll hear Professor Diamond explore:

• How tens of thousands of toxic chemicals are produced, yet many people with MCS are still dismissed.
• There is insufficient research into the harms of chemicals.
• The industries that create most chemical waste.
•  If we can have hope that harmful chemicals that impact people with MCS and others will be regulated.
• And more!

In the latest episode of The Chemical Sensitivity Podcast, we uncover what people with the illness already know — there is no such thing as safe fragrance.

I speak with Professor Gertrud Morlock from Justus Liebig University Giessen in Germany. You'll hear her share:

• What her lab found when screening 42 perfumes.
• Why fragrance formulas are shielded as trade secrets, and how even small amounts can be toxic. 
• How ethanol in perfume enhances skin penetration and persistence.
• And what “unscented” / “fragrance free” labels really mean for people with MCS.

One more thing:

Wendy Kearley is someone many of us know. 

She has lived with debilitating Multiple Chemical Sensitivity 

(MCS) for decades.

Wendy has devoted her life to researching and sharing vital information about MCS.

Wendy recently lost access to her Facebook account.

She needs our help to get critical and non-toxic dental care.

Millions of people live with Multiple Chemical Sensitivity (MCS). 

We are often the best sources of knowledge about the condition.

In this special episode of The Chemical Sensitivity Podcast, I explore listeners’ important questions.

I turn to people with MCS for answers, as well as researchers who specialize in the condition.

We explore:

• How to survive in toxic housing
• Traveling safely with MCS
• Which countries recognize MCS as a disability
• Hospital accommodations
• Why fragrances are so pervasive
• Hormonal links to MCS
• Transparency in product labeling
• Medication sensitivity
• And more

This is an episode about real-life challenges — and the collective wisdom of our community.

For people with Multiple Chemical Sensitivity (MCS), this is often our reality: 

We're told the illness isn’t real — it's just in our heads — and the law refuses to protect us.

In this episode of The Chemical Sensitivity Podcast, Professor Doron Dorfman, a disability law scholar at Seton Hall University School of Law in Newark, New Jersey, in the U.S., explores how:

• People with Multiple Chemical Sensitivity (MCS) face discrimination because courts often dismiss fragrance-free policies as unreasonable.
• No-smoking rules and peanut-free zones could serve as examples for fragrance-free policies.
• Fragrance-free policies are truly not an administrative burden, as some argue.
• And more! 

I'd love your help. I’m running a short listener survey to understand how The Chemical Sensitivity Podcast can best serve people with MCS. 

It’s short, will help guide our next steps, and allow us to grow the podcast and create greater awareness about MCS.

Check out the latest episode of The Chemical Sensitivity Podcast! 

It's called “RVs, Formaldehyde, & Toxic Exposures.” 

I’m speaking with environmental anthropologist, Nicholas Shapiro, Ph.D., associate professor at the University of California in Los Angeles. 

You’ll hear Nicholas explore how after Hurricane Katrina in August 2005, tens of thousands of people were exposed to dangerous levels of formaldehyde in government-supplied RVs. Many developed chronic illnesses and symptoms that could fall under the umbrella of MCS.

The latest episode of The Chemical Sensitivity Podcast is available now! 
 
It's called “Fragrance & Indoor Air Quality.”

I’m speaking with Jeffrey Siegel, Ph.D., Professor of Civil Engineering at the University of Toronto. He is an expert in healthy and sustainable buildings, ventilation, and indoor air quality. A lot of people with MCS contact him, and he has compassion for folks with the illness. 

You’ll hear Professor Siegel explore: 

·       The impacts of indoor pollutants, including from personal care, consumer products, and fragrance.

·       Toxins and cognitive function.

·       The effectiveness of masking and air filtration.

·       The hazards of essential oil (finally, I found someone with deep insights about this!)

·       How we might improve indoor air quality.
