Can simple home cooling save lives in Bangladesh's heat?
NCT ID NCT06979258
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether installing cooling equipment in low-income homes in Bangladesh can reduce heat stress and improve health. About 1,500 participants will have sensors placed inside and outside their homes and wear monitors to track heart rate, sleep, and other health measures. The goal is to see if these interventions lower indoor heat and help people feel better.
