The first step in cleansing is reducing what comes in.
Every day, your body is exposed to thousands of synthetic chemicals — in the water you drink, the air you breathe, the products you put on your skin, the foods you eat from packages, the mattresses you sleep on. Most of these compounds did not exist a century ago. Many of them accumulate in your tissues. A growing body of research links them to nearly every chronic condition I treat in my clinic: hormone disruption, autoimmune disease, neurological symptoms, fertility problems, metabolic dysfunction, and cancers of every kind.
You cannot avoid all of this exposure. You live in the world. But you can reduce it substantially — often by 70 percent or more — by making targeted upgrades in a handful of categories. And reducing the load coming in is the single most powerful thing you can do to support your body's natural detoxification, before any cleanse protocol or supplement ever enters the picture.
This page is a practical guide to those upgrades. It is organized by category and tiered by level of investment — start where you can.
This page is updated periodically as my recommendations refine. Sign up at the bottom to be notified when new resources release.
The Chemistry dimension has three phases: BUILD what the body needs, SUPPORT what is struggling, and CLEANSE what has accumulated. Environmental work sits inside the CLEANSE phase — but it is the part you do first, because the body cannot meaningfully clear what it is still being flooded with.
Most cleanse protocols fail not because the protocol was wrong but because the patient went back into a chemically saturated environment afterward. Reduce the inputs first. Then the cleansing actually holds.
The single most-consumed substance in your body. The single highest-leverage upgrade you can make.
Even in regions with safe tap water by government standards, the water arriving at your faucet typically contains:
A high-quality countertop carbon-based filter — like a Berkey-style gravity filter, a Brita Elite, or a quality activated carbon pitcher. Reduces chlorine, some heavy metals, and improves taste. Not enough to address fluoride, PFAS, or pharmaceuticals — but a meaningful first step.
This is what I recommend for most patients. A multi-stage reverse osmosis system removes essentially everything — chlorine, fluoride, heavy metals, PFAS, pharmaceuticals, microplastics, the lot. The water comes out very clean. Most modern systems include a remineralization stage, which adds back the trace minerals stripped during the RO process. If yours does not, add a pinch of high-quality sea salt (Redmond, Celtic, Himalayan) or a few drops of trace mineral concentrate to your drinking water.
A whole-house system treats every faucet, showerhead, and water outlet. This matters because your skin absorbs chlorine and other compounds during showers — sometimes more than you ingest through drinking water. For patients with sensitive skin, chronic respiratory irritation, or significant detoxification work, whole-house filtration is often worth the investment. If a full whole-house system is not feasible, a quality showerhead filter ($30-80) is a reasonable middle ground.
A short-term option, not a long-term solution. The plastic leaches into the water (especially if bottles are warm or sit in sunlight), and the environmental cost of bottled water is significant. If you must use bottled water temporarily, choose glass over plastic and look for spring water from known sources.
The second most-consumed substance in your body. Most people overlook it entirely.
Indoor air is typically two to five times more polluted than outdoor air, according to EPA estimates. You spend most of your time indoors. The math is what it is.
Common indoor air contaminants include:
The cheapest improvement is removing what shouldn't be there. Eliminate plug-in air fresheners, scented candles, and synthetic-fragrance products. Switch to fragrance-free or essential-oil-based alternatives. Open windows when weather permits. Run the exhaust fan when cooking. Vacuum regularly with a HEPA-filter vacuum.
A quality HEPA air filter in the bedroom is the highest-impact single purchase, because you spend roughly a third of your life in that room and your body does most of its repair work during sleep. Look for True HEPA filtration plus activated carbon (for VOCs). Brands I have had good experience with include Austin Air, IQAir, AirDoctor, and Coway — but the category has many good options now.
For significant indoor air-quality issues or for patients with respiratory or autoimmune conditions, integrating high-quality filtration into the HVAC system (MERV 13 or higher filters at minimum) can make a substantial difference. For homes with known mold problems, professional remediation may be required first.
If your home has a history of water damage, persistent musty smells, or visible mold, mold is likely a significant exposure. Mold-related illness is increasingly recognized as a root cause of complex chronic conditions. For suspected mold issues, ERMI (Environmental Relative Moldiness Index) or HERTSMI-2 dust testing is a reasonable first step. Significant mold problems require professional remediation — this is not a DIY situation.
What you put on your skin gets into your body. The skin is not a barrier — it is a permeable organ.
Reading every label is unrealistic. Focus on the worst offenders:
The EWG Skin Deep database (ewg.org/skindeep) rates over 90,000 personal care products on a 1-10 hazard scale. Their Healthy Living app lets you scan barcodes in stores. This is the most efficient way to upgrade your products without learning the chemistry yourself.
Start with the products that touch the largest surface area or stay on the longest:
Many conventional cleaning products are some of the most toxic substances in the average home. They are also the easiest category to upgrade.
For 80 percent of household cleaning, you do not need specialized products at all. The traditional kitchen pharmacy works fine:
The EWG Healthy Living app rates cleaning products too. Look for products with clear, simple ingredient lists. Brands like Branch Basics, Seventh Generation, Method, and ECOS have generally clean options, though even within these brands product-by-product evaluation matters.
What touches your food becomes part of your food.
The primary concern with plastic food storage is endocrine-disrupting chemicals (BPA, BPS, phthalates) that leach from the plastic into the food — especially when heated, microwaved, or in contact with fats and acids.
This is one of the highest-impact upgrades in the kitchen. What you cook in becomes part of what you eat.
The science on chronic low-level electromagnetic field (EMF) exposure remains contested in the conventional medical literature, but a growing body of research suggests biological effects. My clinical experience has been that some patients respond meaningfully to reducing their exposure.
For patients who want to go further, grounding (also called earthing) — direct skin contact with the earth, or use of a grounding mat or sheet — is a low-cost, well-tolerated practice that many patients report benefits from. The research on grounding is still small but growing, and the downside is minimal.
You spend a third of your life in this room. The materials touching your skin and the air you breathe in this space matter disproportionately.
Most conventional mattresses are made from polyurethane foam and treated with flame retardants — both significant sources of off-gassing for years. Newer mattresses are often the worst.
If a new mattress is not in the budget, encasing your current mattress in a high-quality organic cotton mattress encasement can reduce exposure significantly.
Buckwheat hull, organic cotton, organic wool, and organic latex are all reasonable choices. Replace memory-foam pillows when budget allows.
You cannot do everything at once. You should not try. Here is the priority sequence I recommend for most patients:
This is not about purity. It is not about creating a sterile, anxiety-driven life. The goal is reducing the cumulative load on your body's elimination systems so they can do their work.
You will not be able to control everything in your environment. You will eat at restaurants. You will visit friends with conventional everything. You will travel and stay in hotels. None of this matters in any single instance. What matters is the steady baseline you create in your home — the place your body spends most of its time, and the place where it does most of its healing.
A 70 percent reduction in environmental load, sustained over years, is more valuable than 100 percent perfection for a month.
