NCT06579950 · RECRUITING
Assessing the Effects of Cool Roofs on Indoor Environments and Health
This trial is testing whether painting rooftops with reflective cool-roof coatings lowers indoor temperatures enough to improve the health of people living in hot, low-income housing. Researchers are measuring dozens of outcomes — heart rate, blood pressure, sleep, cognition, mood, and more — across five countries. This is a Phase NA pragmatic trial, meaning it is a real-world intervention study, not a drug trial. Details on U.S. enrollment are not available.
You may qualify if
- Permanent household resident.
You're excluded if
- Roof damage, inaccessible or instability of roof adversely affecting cool roof coating application.
- Participant unable to provide written/verbal informed consent.
