Reducing harmful indoor heat in low-income homes in Dhaka

Understanding heat stress and adverse health outcomes in vulnerable populations in Bangladesh: Can we move the needle by designing low-cost, feasible and culturally acceptable interventions?

NIH-funded research University of California Berkeley · NIH-11321199

This project tests low-cost, culturally acceptable cooling changes in homes to lower heat stress and heart strain for adults living in informal settlements in Dhaka, Bangladesh.

What this research studies

If you live in an informal neighborhood in Dhaka without air conditioning, researchers will measure how hot your home gets and how your body responds using simple wearable sensors. They will try low-cost home changes aimed at keeping your living space cooler and see whether those changes lower heart rate and heat exposure. The team will also ask residents if the changes are easy to use and acceptable in daily life. If the changes work, they will consider whether they could be scaled up to help more vulnerable households.

Who could benefit from this research

Good fit: Adults (21+) living in informal settlements of Dhaka, especially those in homes with corrugated iron roofs or without access to air conditioning, are the ideal candidates.

Not a fit: People who already have reliable air conditioning, live outside Dhaka informal settlements, are younger than 21, or are not willing to have simple home modifications are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the interventions could lower indoor heat exposure and reduce heat-related strain on the heart and other heat-linked health problems for low-income adults.

How similar studies have performed: Some prior small studies show that building-level cooling and shading can lower indoor temperatures, but testing low-cost, culturally tailored home changes and measuring heart-rate effects in Dhaka's informal settlements is relatively new.
