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.
House is located in an informal settlement in an urban area in Bangladesh
The house has a corrugated iron roof and corrugated iron walls
The household plans to remain in the house from Feb-Nov
There is an inhabited structure about the house
The landlord does not allow the proposed intervention
Lives in an eligible household
Has access to air conditioning in their home or place of work
Single group
Cooling intervention
Other interventionInfrastructure and/or equipment that cools the house in the hot season
Heart rate
resting heart rate (beats per minute, bpm), where lower heart rate is better
Heart rate variability
resting heart rate (beats per minute, bpm) variability, where higher variability is better
Sleep quality
Self-reported sleep quality and number of minutes in rapid eye movement (REM), as recorded by a fitness watch, where more time in REM is better
Irritability
Self-reported irritability, as measured by the Brief Irritability Test (BITe), where a lower score is better
Environmental Symptoms
Environmental symptoms, as measured by the abbreviated environmental symptoms questionnaire, where a lower score is better
