Who could benefit from this research

Could help

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.

Less likely to help

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.

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.

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 gone: 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.
