1. Remove Products with Formaldehyde
Formaldehyde is a known carcinogen used in many household products as a binding agent. It’s commonly found in:
- Pressed-wood furniture (like particle board, plywood, or MDF)
- Synthetic carpets and fabrics
- Low-cost cabinetry or wall paneling
What to do instead:
- Look for solid wood furniture (FSC-certified is best).
- Avoid products containing methanal, methylaldehyde, or oxomethane.
- Choose items labeled GREENGUARD Gold-certified, EPA TSCA Title VI–compliant, or NAF/ULEF, which ensure low or no formaldehyde emissions.

2. Ditch Phthalates and PVC
Phthalates are plasticizers often added to vinyl (PVC) and synthetic fragrances. They’ve been linked to breast cancer, endocrine disruption, asthma, and more.
Common sources include:
- Vinyl flooring and shower curtains
- Plastic food containers (especially #3 PVC)
- Scented lotions, candles, and air fresheners
What to do instead:
- Use glass or stainless steel for food prep and storage.
- Choose fragrance-free or 100% essential oil–scented personal care and home products.
- Replace vinyl items with natural materials like cotton, linen, and wool.

3. Say No to Synthetic Fragrances
Artificial fragrance is one of the biggest sources of indoor air pollution. It can contain hundreds of hidden chemicals—like DEP, a phthalate linked to hormone disruption and used to make scents last longer
Avoid:
- Plug-in air fresheners
- Scented candles (unless the brand lists full ingredients and uses essential oils only)
- Room sprays, perfumes, and “fragrance blends” with vague terms like parfum or fragrance on the label
Choose instead:
- Products labeled “fragrance-free” or that state “scented with 100% essential oils”
- Candles made with safer waxes (ex: beeswax or coconut-soy wax, a cotton wick), and no added dyes or synthetic fragrance
- Look for labels like phthalate-free, paraben-free, or EWG Verified
- Improve air quality with a HEPA air purifier, cracked windows, or diffusing essential oils in moderation
These changes aren’t just for people with sensitivities—they’re better for everyone, especially in healing environments.

4. Avoid Aerosols and Sprays
Aerosol sprays release ultrafine particles and chemical propellants that linger in the air, irritate the lungs, and lower indoor air quality. They’re especially risky for those with asthma, allergies, or weakened immune or respiratory systems.
Avoid:
- Aerosol hairsprays and deodorants
- Disinfectant sprays with ingredients like quaternary ammonium compounds (quats)
- Insecticides and air-freshening sprays labeled with “fragrance,” “butane,” “propellant,” or “isobutane”
Choose instead:
- Pump or trigger-spray bottles with simple, non-aerosol delivery
- Cleaning solutions made with diluted white vinegar, hydrogen peroxide, or castile soap
- Essential oil misters for occasional natural scent
- Products labeled “aerosol-free,” “propellant-free,” and “fragrance-free” or scented with essential oils only
Even small changes—like switching to refillable glass bottles with safer ingredients can reduce daily exposure and support better air quality at home.

5. Say Goodbye to Styrofoam
Styrofoam (also called polystyrene) contains styrene, a chemical classified as a probable human carcinogen.
Styrene can leach into food and drink, especially when heated or used with hot or acidic items.
Avoid:
- Disposable foam cups and plates
- Foam takeout containers
- Microwaving or storing anything in Styrofoam
- Products labeled “PS” or marked with recycling code #6
Choose instead:
- Reusable containers made from ceramic, glass, stainless steel, or bamboo
- Paper-based takeout containers (uncoated), or bring your own food-safe containers when possible
- Always transfer hot food out of any foam or plastic packaging before eating or reheating
Look for packaging labeled BPA-free, PFAS-free, or certified food-safe for added peace of mind.
6. Use Natural and Low-VOC Finishes
Many paints, flooring adhesives, and finishes release VOCs (volatile organic compounds) that can pollute indoor air and trigger headaches, dizziness, respiratory issues, and even long-term health effects.
For anyone with a weakened immune system, including cancer patients, minimizing VOCs is essential for creating a safer, healing environment.
What to avoid:
- Conventional paints and primers that list VOC content over 50 g/L
- Adhesives and sealants that contain formaldehyde, toluene, or acetone
- Synthetic carpets and rugs with chemical-based backings or stain treatments
What to choose instead:
- Zero-VOC or low-VOC paints (look for third-party certifications like Green Seal, GREENGUARD Gold, or MPI Extreme Green)
- Solid hardwood flooring finished with plant-based oils or water-based sealants
- Rugs made of natural fibers like organic cotton, wool, or jute with no added flame retardants or stain resistance treatments
Reducing VOCs isn’t just about air quality, it supports your immune system, reduces chemical burden, and creates a space that truly feels clean and calming.

Bringing in the Healing Elements of Holistic Design
Aside from removing toxins, creating a healing space also is about adding in the elements that support your body, mind, and spirit. This is where the holistic side of design can make a real difference, especially for those navigating cancer.
Here’s how to create a space that feels safe, calming, and deeply restorative from every angle:
Natural Materials & Living Elements
Natural textures can calm the nervous system and lower stress levels—something your body deeply needs while healing.
Choose:
- Solid wood, organic cotton, linen, wool, clay, and stone
- Houseplants like aloe vera or peace lilies to improve air quality and lift mood
- Crystals such as malachite for symbolic support in detoxification and cellular repair
Shop: Malachite – Amazon
Sunlight & Circadian Lighting
Light influences everything from immune function to sleep and emotional balance.
What helps:
- Let in natural light—open curtains, clean windows, and position seating in sunny spots
- Use full-spectrum light bulbs in darker areas to mimic natural daylight
- Avoid bright overhead lighting at night—opt for warm, dimmable lamps instead
Shop: Full-Spectrum Light Therapy Lamp – Amazon
Shop: Himalayan Salt Night Light – Amazon
Supportive Sound & Music:
Sound has the power to ease anxiety, regulate heart rate, and support healing.
Try:
- Calming instrumental music, nature sounds, or 432 Hz frequency tracks
- Minimizing background noise
- Using a white, or pink noise machine to support deeper rest, especially in noisy environments
Shop: Bluetooth Sound Machine – Amazon
Air & Energy Flow:
Stale air and stagnant energy can weigh down both mood and the healing process.
Simple shifts that help:
- Use a HEPA air purifier to reduce dust, VOCs, and indoor pollutants
- Open windows daily—even briefly—for fresh airflow
- Clear clutter and keep pathways open to allow energy to move more freely (a key Feng Shui principle)
PFAS (“Forever Chemicals”) in Water-Resistant & Stain-Repellent Products
PFAS are chemicals found in many “stain-resistant” or “waterproof” products—and they don’t break down. They build up in the body and have been linked to kidney and testicular cancer, thyroid disease, and immune issues.
Where they hide:
- “Stain-resistant” sofas, carpets, and outdoor cushions
- Nonstick cookware (like Teflon)
- Water-repellent clothing and gear
What to choose instead:
- Products labeled PFAS-free
- Cast iron or stainless steel cookware
- Sofas and rugs made from natural, untreated fabrics—machine washable when possible
Shop: PFAS-free Cookware – Amazon
Shop: Organic Cotton Couch Cover – Amazon
EMFs (Electromagnetic Fields) & Radiation Exposure
While research is ongoing, high EMF exposure is a growing concern—especially for people with cancer or compromised immune systems.
High-EMF sources:
- Wi-Fi routers, cell phones, tablets
- Wireless baby monitors, microwave ovens, smart meters
Reduce exposure by:
- Keeping electronics away from sleeping and rest areas
- Turning off Wi-Fi at night or using a Wi-Fi timer switch
- Using Ethernet cables where possible and unplugging devices when not in use
- Trying EMF-shielding fabrics or paint if sensitivity is high
Shop: Wi-Fi Timer Plug
Shop: EMF Reducing Paint
Shop: Low-EMF Shielding Blanket
Mold & Moisture
Mold is more than a nuisance—it can weaken the immune system and trigger respiratory symptoms, which is especially risky for cancer patients.
How to prevent it:
- Use a dehumidifier in damp areas like bathrooms or basements
- Fix leaks quickly and ventilate well after showers
- Use mold-resistant paint in humid spaces like kitchens and laundry rooms
Shop: Bathroom Dehumidifier – Amazon
