Heat Stress Exposure Among Low-Income Residents in Bangladesh and Evaluation of Indoor Interventions

The goal of this clinical trial is to learn if infrastructure and equipment installed to cool homes reduce adverse health outcomes. The main questions it aims to answer are: What is the impact of the intervention on indoor heat stress? What is the impact of the intervention on personal exposure to heat stress? What is the impact of the intervention on health outcomes, including heart rate, and heart rate variability, and sleep quality? Participants will have cooling infrastructure and/or equipment installed in their home; have heat stress sensors installed inside and outside their home and wear personal heat stress monitors; allow some biological functions such as heat rate, heat rate variability, and sleep quality.
