Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does the implementation of cool roofs reduce indoor temperatures and related heat stress in rural households?
* Does heat literacy education improve community awareness and behaviors related to coping with extreme heat?
Researchers will compare four groups: one receiving both cool roofs and heat literacy interventions, one receiving only the cool roof intervention, one receiving only heat literacy education, and a control group receiving neither intervention. Participants will be asked to:
* Have their roofs painted with UV-resistant white paint (for cool roof intervention groups).
* Participate in educational sessions and training on heat-related health risks and coping strategies (for heat literacy intervention groups).
* Complete baseline and follow-up surveys at 3, 6, and 12 months.
* Wear a Garmin Vivosmart 5 sensor for two weeks during each data collection period to monitor heart rate, physical activity, and sleep patterns.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants will be randomly selected from the SEACO health database, encompassing five operational sub-districts. Eligible participants include adults aged 18 years and above, living in single-story houses with suitable roofing materials. They will be randomly assigned to one of four groups: one receiving both interventions, one receiving only the cool roof intervention, one receiving only heat literacy education, and a control group receiving neither intervention. This 2 x 2 factorial design will allow researchers to compare the effects of each intervention individually and in combination.
Data collection will occur at baseline and three follow ups, intended to do 3 months, 6 months, and 12 months. SEACO data collectors will visit participants' homes to install SwitchBot heat and humidity measurement devices, conduct surveys, and take physical measurements. Participants will also wear Garmin Vivosmart 5 sensors for two weeks during each data collection period to monitor their heart rate, physical activity, and sleep patterns. We will also conduct the basic measurements such as height, weight, blood pressure, blood glucose and HbA1c. The surveys will gather information on socioeconomic and demographic characteristics, self-reported illnesses, heat exposure, heat adaptation behaviors, heat literacy, cooling strategies, self- reported sleep quality, mental health and quality of life.
The study aims to determine whether cool roofs and heat literacy education can effectively reduce indoor temperatures, improve heat adaptation behaviors, and ultimately mitigate the health risks associated with extreme heat. By analyzing data from both interventions and their combined effect, the research seeks to develop a theoretically informed, evidence-based, and culturally sensitive community-based heat adaptation program for rural Malaysia. This program could serve as a model for other climate-vulnerable regions, providing valuable insights into sustainable and practical approaches to addressing the health impacts of climate change.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A (Cool Roof and Heat Literacy Interventions)
Cool roof intervention: Roofs will be painted with UV-resistant paint to reduce thermal absorption.
Heat literacy intervention: Participants will receive education and training on heat-related health risks and coping strategies.
Heat Literacy Intervention
The behavioral intervention aims to improve heat literacy among participants through an 8-12 week education and training program. It includes three main modules: enhancing community awareness of hot weather, recognizing and responding to heat-related illnesses, and teaching personal cooling strategies. Participants will use SwitchBot meters to monitor indoor temperature and humidity, access real-time weather information, and learn about heat wave warnings. They will receive educational materials, including infographics, videos, and one-to-one training from field staff. The content of intervention and delivery methods will be refined through co-design workshops with stakeholders and community members to ensure they are practical and culturally appropriate. The goal is to equip participants with the knowledge and skills to protect themselves from extreme heat, resulting in better heat adaptation behaviors and improved health outcomes.
Structural (Cool Roof) Intervention
The structural intervention in this study involves implementing cool roofs to reduce indoor temperature and mitigate the effects of extreme heat in rural Malaysian communities. Selected households will have their roofs painted with UV-resistant paint, which reflects direct sunlight and reduces thermal absorption. This intervention aims to decrease the amount of solar energy absorbed by the roof, thereby lowering indoor temperature and reducing the physiological heat strain on residents. By maintaining cooler indoor environment, the cool roof intervention seeks to alleviate the health risks associated with prolonged exposure to high temperature.
Group B (Cool Roof Intervention Only)
Cool Roof intervention: Roofs will be painted with UV-resistant white paint to reduce thermal absorption
