Preliminary research suggests…
A systematic review links housing conditions (heating, ventilation, refurbishment) to improved respiratory outcomes, quality of life and mental health. Evidence is observational and confounded by socioeconomic factors, so personal-scale conclusions are cautious (Grade C).

Common misconceptions
- Indoor environment is cosmetic, it is linked to real health outcomes
- One perfect factor is enough, light, air and temperature interact
What we won't claim
- Optimizing your home cures illness
- Indoor tweaks replace medical care
When to seek a professional
- Unsafe indoor conditions (mold, damp, inadequate heating, CO risk) → qualified housing/environmental-health professional
