Healthy Housing: Connecting Research, Policy, and Communities

This week, we sit down with Amanda Reddy, Executive Director at the National Centre for Healthy Housing, to explore a question that fundamentally challenges how we think about housing quality and public health: What if the single biggest barrier to transforming housing quality isn't our lack of scientific knowledge or technology—but our complete failure to recognise that the places where we spend 70 percent of our lives, our homes, are either actively supporting or systematically undermining our health, and that fixing housing for the most vulnerable fixes it for everyone?

Key Topics Discussed:

Lead Is Not a Solved Problem: Half a million children in the United States are still exposed to lead levels that threaten their ability to learn and thrive every year. Lead affects neurodevelopment, lowers IQ, impairs executive function and increases the risk of conduct disorders. But it also affects adults. A World Bank study estimated that lead exposure causes five and a half million deaths globally each year, more than AIDS, malaria and road traffic deaths combined. The amount of lead required to poison a child is invisible. Imagine a sugar packet of lead contaminated dust spread evenly over an American football field. That is still enough to be hazardous. You cannot clean your way out of this problem. You have to eliminate the source.

The Three Pillar Strategy: The National Centre for Healthy Housing operates through research, policy advocacy and community capacity building. They identify what works through rigorous evidence, advance those solutions through federal, state and local policy changes, and then support communities to implement those solutions on the ground. But they do not arrive with predetermined answers. Communities own the bus. They decide where they are going, how fast and what route to take. The Centre brings expertise, tools and evidence to help navigate barriers, but the solutions are shaped by the people who live the experience every day.

Climate, Housing and Health Collide: Extreme heat now affects 70 percent of Americans. Housing is central to how communities weather climate events, whether heat, cold, hurricanes or wildfires. But much of the existing housing stock was not built for the climate we are experiencing today, let alone the climate we will face in 2050. Seventy percent of the homes that will exist in 2050 are already built. Energy efficiency retrofits that sealed homes to save energy are now trapping heat. Communities are ca
