✓Well SupportedUsing glass, stainless steel, or ceramic for food and beverage storage can reduce microplastic exposure.

✓Well SupportedExposure to white and blue light in modern environments can delay sleep onset by reducing melatonin production.

✓Well SupportedUsing a reverse osmosis filter on tap water reduces total dissolved solids to approximately 13 ppm.

◐Partially SupportedHVAC systems should be the primary defense for indoor air quality, with air filters serving as an add-on.

✓Well SupportedEnsuring the bedroom is completely dark is important for good sleep.

✕Not SupportedNonstick pans, including ceramic and Teflon, should be avoided due to potential PFAS and Teflon aerosolization.

◐Partially SupportedTinted window films that block 99% of UVA and UVB rays can be used to protect skin from sun damage.

◐Partially SupportedImplementing health systems and habits can put one's life on autopilot, avoiding repetitive decision-making and anxiety about toxins.

✓Well SupportedWearing an eye mask at night is a potentially helpful measure to achieve darkness for sleep when ambient light is unavoidable.

◐Partially SupportedDuring high UV index periods, protection such as an umbrella, sunscreen, or hat should be used to minimize skin damage.

✕Not SupportedScented cleaning supplies and air fresheners release volatile organic compounds (VOCs) that can react to form formaldehyde, a known carcinogen.

◐Partially SupportedKeeping a Wi-Fi router outside the bedroom and turning off Wi-Fi, mobile, and Bluetooth on a phone while sleeping minimizes EMF exposure.

◐Partially SupportedThree in five fire-related deaths in homes are caused by malfunctioning or absent smoke alarms.

◐Partially SupportedMERV 13 filters capture more toxins than MERV 8 filters, which capture about 30% of PM 2.5.

◐Partially SupportedBryan Johnson is replacing his gas stove with an induction stove for health reasons.

◐Partially SupportedA portable HEPA air purifier is a quick win for improving bedroom air quality and promoting deep sleep.

◐Partially SupportedIndoor air quality can be measured using sensors for PM2.5, PM1, PM10, VOCs, CO2, and AQI.

◐Partially SupportedWater can be a significant source of contaminants in the home, including heavy metals, PFAS, and microplastics.

◐Partially SupportedHard floors are preferred over carpets because carpets harbor 10 times more dust, allergens, and microbes.

✕Not SupportedBryan Johnson does not trust the 'organic' food label due to his testing experiences.

◐Partially SupportedNon-tinted glass allows 37% of UVA to pass through, indicating substantial UVA exposure even indoors.

✕Not SupportedGas burners spike nitrogen dioxide and fine particles, linked to approximately 13% of childhood asthma cases in the US.

◐Partially SupportedReverse osmosis water filtration systems typically cost between a few hundred to over a thousand dollars and require filter maintenance every few months.

◐Partially SupportedLab testing of ingredients can reveal more than what is listed on the label.

◐Partially SupportedPink noise is preferable to white noise as it is less high-pitched and mimics natural sounds.

◐Partially SupportedUsing commercial-grade HEPA air filters in the bedroom can ensure clean air quality during sleep.

◐Partially Supported10 lux of light can halve melatonin production and fragment sleep.

◐Partially SupportedAchieving a pristine home environment for health is a step-by-step journey that takes time and patience.

◐Partially SupportedUsing a noise machine, particularly pink noise, can improve sleep steadiness and reduce awakenings.

◐Partially SupportedUsing a vacuum with a HEPA filter twice a week can mitigate dust, allergens, microbes, and 99.97% of microplastic particles, preventing chronic irritation and respiratory issues.

◐Partially SupportedUsing an HVAC filter with a MERV rating higher than the system can handle can cause problems.

◐Partially SupportedAir purifiers and HVAC filters can improve indoor air quality.
