The Big Picture

Published March 2026   |    Updated March 2026


If you’ve found a product poses a real risk of harm to your health, you might choose to use it anyway.

On the other hand, even if a product is perfectly safe, you might not purchase it.

What these have in common is zooming out to see the bigger picture that the framework sits within: the bigger picture, which includes everything else that contributes to your health, your life in general, other people, and the environment.

Four Exceptions to the Framework

1. The Bigger Picture of Your Health

Your health is not a single variable. It's the result of an enormous number of interacting factors — genetics, movement, nutrition, sleep, relationships, stress, existing medical conditions, medical care, and yes, environmental exposures including what's in your home.

If you ever find yourself agonizing over a material decision, or feeling like your home has to be perfectly non-toxic before you can relax, I want you to picture something like a pie chart. Environmental exposures — including everything indoors — are one slice. A genuinely important slice, and one worth addressing. But not the only slice, and not always the biggest one.

Some people focus almost entirely on movement and nutrition and mostly ignore what's in their home. Some people take their medication every day and prioritize avoiding outdoor air pollution. Some people focus on strong relationships and good sleep. All of these are legitimate paths toward health. The goal isn't to optimize every slice simultaneously — it's to do the best you can with whichever combination makes sense for your life.

2. Life Enjoyment

I think about this the way I think about food. My ideal diet includes lots of vegetables, whole foods, and home cooking. It also includes takeout Thai food in a plastic container once in a while — and not stressing about it. Both are part of an actually livable version of eating well.

The same goes for non-toxic living. Apply the Precautionary Principle where it costs you nothing: swap the air freshener, choose a GOTS-certified cover, ask your dry cleaner whether they use wet cleaning. But hold onto the things that bring you genuine joy, even if they're not perfect.

I will never give up my heated polyester blanket in the winter. It brings me joy. It is worth it. That calculation is mine to make, and yours is yours to make.

You don't have to be perfect. You don't even have to be consistent. You can avoid PFAS-coated cookware and still own a vinyl shower curtain you haven't gotten around to replacing. You can have a beautifully non-toxic bedroom and barely think about your living room. You can make progress without making it a project.

3. Before You: The Workers Making It

Here is where it starts getting a little more tricky: every product has a life before it reaches you. The chemicals used to process textiles, treat wood, apply coatings, or manufacture foam are often present in much higher concentrations in the factory they’re made in than they ever will be in your home. Workers in these facilities are exposed at levels that dwarf what you'll encounter as an end user. This is why Prop 65 warnings sometimes say more about factory conditions than about your living room, and why certifications like GOTS matter beyond what's in the final product: they set standards for the entire production process, including what workers are exposed to.

What's healthy for you as the end user isn't always the healthiest option for the people making it. It’s worth keeping in mind, even if the answer isn’t always clear or consistent, and doesn't change your immediate purchasing decision.

4. After You: Other People and The Environment

The trickiest caveat of all: the chemicals in a product you discard don't disappear. They enter landfills, wastewater treatment, soil, and water systems, and eventually some cycle back into the food and water supply. PFAS in particular are notorious for this: they've been found in drinking water far from any known point source, carried there through the water cycle.

This is part of why avoiding certain chemical classes matters at a societal level even when individual exposures seem small, and why buying only what you need matters. This is a major criticism of the wellness world, and I understand why.

An example: an OEKO-TEX certified polyester blanket poses relatively low risk to your health, and its accessibility compared to organic alternatives is important. But polyester is petroleum-derived, and the extraction and refinement involved carries costs for the planet and the communities near those facilities, as well as the landfill that will contain it in the future, because polyester is a plastic that doesn’t break down easily. This is not an argument against buying OEKO TEX certified polyester. It's an acknowledgment that buying healthier products for your home isn't a complete answer to a much larger question. That conversation is global, political, and ethical, and well beyond what a few paragraphs here can resolve. But, I think it’s important for all of us to consider, and it’s important to me that you know I’m aware of this complexity.
