About

This study aims to understand whether simple, low-cost interventions, such as improved home cooling, practical advice, and minor home modifications, can help protect people's health and quality of life during periods of extreme heat in rural, low-income villages of Matiari, Pakistan.

Key Questions the Study Seeks to Answer:

1. Can these interventions reduce heat-related health problems such as dizziness, headaches, and heatstroke and quality of life?
2. Can they lower indoor temperatures and improve sleep quality, comfort, and daily functioning?

To answer these questions, researchers will compare communities where families receive heat-related support and information with similar communities that do not, to assess any differences in health and well-being.

What Participants Can Expect:

• Answer questions about their health, living conditions, and how they cope with heat
• Have small temperature sensors placed inside their homes
• Some participants may wear a lightweight wristband that tracks sleep and heart rate
• In selected households, cooling improvements will be made, such as adding shade, applying reflective roof paint, or enhancing airflow

Purpose:

This study seeks to identify affordable and effective strategies to help families stay safe during extreme heat, and to use these insights to support other vulnerable communities facing similar challenges.

Heat Adaptation Bundle

Experimental group

Description:

The Resilience and Heat Adaptation Bundle (ReHAB) consists of three components; community education and awareness, personal lifestyle and cooling behavior modification, and participatory local structural and environmental heat mitigation solutions. The behavioral and educational interventions will be delivered through community mobilization whereas structural interventions will encompass modifications in the existing structures to lower the indoor ambient temperature and reduce heat effects.

Treatment:

Other: Participatory local structural and environmental heat mitigation solutions

Behavioral: Community education and awareness, and personal lifestyle and cooling behavior modification

Control

No Intervention group

Description:

The control arm will not receive any intervention.
