Assessing the Effects of Cool Roofs on Indoor Environments and Health in Colima, Mexico
This trial is testing whether painting rooftops with a sunlight-reflecting cool roof coating lowers indoor temperatures enough to improve health in homes in Colima, Mexico. Researchers are measuring a wide range of outcomes including heart rate, blood pressure, sleep, mood, cognition, and heat-related illness. This is a Phase NA randomized controlled trial — meaning it is a real-world intervention study, not a drug trial, and it is evaluating practical effects rather than drug safety or efficacy.
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.
