The Home Reset
Your Home Is the New Cigarette Smoke The 7 Indoor Exposure Sources You Ignore (But Shouldn’t)
Data Drop: The Invisible Exposures Inside Your Home
We spend ~90% of our time indoors — yet most of the risk conversation focuses outside.[1] That’s a problem, because our bodies are constantly interacting with hidden chemical and particulate exposures at home:
1. Microplastics in indoor air
Emerging research estimates humans may inhale up to ~68,000 microplastic particles per day indoors, with carpets, textiles, and synthetic materials contributing heavily.[1][2]
2. PFAS (“forever chemicals”) in dust & air
Indoor media like dust, textiles, and treated surfaces carry PFAS. These compounds do not break down, accumulate in the body, and may contribute to immune, hormonal, and metabolic disruption.[3]
3. Flame retardants in pillows & foam
Older upholstered furniture contains flame retardants that migrate into dust and air and can enter the body by inhalation or contact.
4. Volatile Organic Compounds (VOCs)
VOCs from paints, sealants, cleaning products, and synthetic materials can be 2–5x higher indoors than outdoors.*[4]
5. Synthetic fragrances & cleaners
Fragrance chemicals are complex mixtures that linger; many are linked to respiratory irritation and endocrine disruption.
6. Off-gassed materials
Pressed wood, adhesives, and finishes continue releasing VOCs well after installation or purchase.
7. Secondary pollution from electronics & devices
Certain air purifiers and electronics generate ozone or particulates that react with indoor chemicals.
These sources may not produce smoke, but their biological impact — chronic inflammation, oxidative stress, and subtle metabolic shifts — accumulates with every breath.
Longevity Hack: Start With Air + Dust, Not Diet
Before expensive tech or extreme resets, focus on what your body touches and breathes most:
Ventilate first. Even a few minutes of cross-ventilation dilutes accumulated indoor pollutants.
HEPA vacuum + wet dust. Dry dusting redistributes particles — wet methods trap them.
Bedroom priority. Most time spent here + low ventilation = highest exposure hours.
Swap problem products over time. Replace fragranced cleaners and high-VOCs items organically as they wear out.
Natural materials where possible. Wool rugs, natural wood, cotton instead of synthetics reduce long-term shedding.
Small, consistent environmental shifts influence your biology more than any single supplement stack over the long haul.

RightDose Take
Longevity isn’t just biochemical — it’s ecological. Your home is your longest-lasting environment. Treat it with the same precision you treat sleep, stress, and nutrition.
Next week, we shift from what’s in your air and dust to what fuels your body—your metabolism, energy, and hormone balance, backed by data.
Subscribers get early access to our upcoming beta, where we translate this data into clear product and home choices.
