18 questions that reveal how well your home is actually supporting your health. Developed from the WELL Building Standard and years of wellness-centred residential practice.
The average American spends over 90% of their time indoors. The quality of that environment — the air you breathe, the light you wake up to, the materials surrounding you, the noise you absorb — directly shapes your energy, sleep, mood, and long-term health.

The air inside most homes is 2 to 5 times more polluted than outdoor air. Poor ventilation, off-gassing materials, and uncontrolled moisture are the primary culprits — and most homeowners are unaware of the problem.
Does your home have a mechanical ventilation system — such as an ERV or HRV — or a dedicated fresh air strategy?
Without fresh air exchange, CO₂ levels rise overnight. This impairs cognitive function and sleep quality.
Are the finishes, flooring, paints, and adhesives in your home low-VOC or zero-VOC certified?
Volatile Organic Compounds off-gas from conventional materials for years, contributing to headaches, respiratory issues, and long-term health risks.
What rating are your HVAC filters, and how consistently are they replaced?
Standard fiberglass filters capture less than 20% of fine particulate matter. MERV-13 and above captures over 85%.
Is there any visible mold, persistent musty odour, or known moisture intrusion in your home?
Mold releases mycotoxins that cause respiratory illness, fatigue, and cognitive fog — conditions often misdiagnosed for years.
What your home is made of matters. Natural, minimally processed materials support a healthier indoor environment than synthetic alternatives manufactured for cost or convenience.
How would you describe the primary materials in your home — floors, walls, cabinetry, and furniture?
Plastics, foams, and vinyl composites often contain plasticizers and flame retardants that off-gas continuously and accumulate in household dust.
Are your upholstered furniture, mattresses, and insulation free from polyurethane foam as a primary fill?
Polyurethane foam is a significant source of flame retardant chemicals linked to hormonal disruption and neurological effects, particularly in children.
What are the kitchen and bathroom surfaces in your home made from?
Laminate and resin-based surfaces degrade over time and contribute to indoor air quality decline through off-gassing adhesives and coatings.
Light is the primary signal that regulates your sleep-wake cycle. Most homes deliver the wrong kind of light at the wrong time of day, disrupting sleep without homeowners realising the cause.
How much natural daylight do your main living areas and bedroom receive during the day?
Natural daylight suppresses melatonin production during the day, which in turn improves night-time sleep quality and depth.
How would you describe your evening lighting at home after 8pm?
Blue-spectrum light in the evening delays melatonin onset by 1 to 3 hours, suppressing sleep quality even when you feel tired.
Can your bedroom be made fully dark at night — no light from outside or hallways?
Even low levels of ambient light during sleep disrupt REM cycles and increase risk of metabolic disruption.
Temperature inconsistency is not just uncomfortable — it is a sign of an inefficient building envelope that wastes energy, promotes moisture, and compromises your health.
How consistently comfortable is the temperature throughout your home, room to room?
Temperature inconsistency indicates air sealing deficiencies and thermal bridging that drive energy costs and moisture risk.
Does your home maintain indoor humidity between 40 and 60% year-round?
Below 30%: skin and respiratory irritation, virus transmission increases. Above 65%: mold risk escalates rapidly.
Can your bedroom maintain a nighttime temperature between 65 and 68°F?
Core body temperature must drop 2 to 3 degrees F to initiate sleep. A cool bedroom supports this process naturally.
Chronic noise exposure, even at levels below conscious awareness, elevates cortisol, disrupts sleep, and degrades cognitive performance over time.
How isolated is your bedroom from traffic, HVAC noise, and household sound at night?
The WHO recommends nighttime outdoor noise below 40dB. Most urban and suburban bedrooms routinely exceed this threshold.
Can you work or rest at home without frequent noise interruptions from other rooms or outside?
Sound privacy enables deep work and recovery. Both are impaired in acoustically open floor plans without thoughtful architectural design.
How a space is organised, its proportions, its connection to nature, and its support for daily movement all have measurable effects on mood, stress, and long-term health.
Do the areas where you spend the most time have views to the outdoors — trees, sky, or greenery?
Research on biophilic design shows that even brief visual access to nature lowers cortisol and blood pressure measurably.
Does your home's layout naturally encourage movement throughout the day?
Passive architecture can either encourage or suppress movement. The layout itself is a measurable health determinant.
After a long day, does your home feel genuinely calm and restorative?
This is the ultimate test: your home should actively restore you, not passively receive you. Design, proportion, light, and materials all contribute.
