Solutions are needed to reduce heat exposure in communities. Sunlight-reflecting cool roof coatings passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions globally - for example in informal settlements, slums, and low-socioeconomic households - are especially vulnerable to increased indoor heat exposure.\n\nHeat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are being experienced in communities least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use can promote physical, mental and social wellbeing in occupants.\n\nThe long-term research goal is to identify viable passive housing adaptation technologies with proven health and environmental benefits to reduce the burden of heat stress in communities affected by heat globally. To meet this goal, the investigators will conduct a cluster-randomized controlled trial to establish the effects of cool roof use on health, indoor environment and economic outcomes in five urban climate hotspots: Ouagadougou, Burkina Faso; Colima, Mexico; Ahmedabad, India; Niue; and Tavua, Fiji.",[158,159,160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175,176,177,178,179,180,181,182],"Resting Heart Rate","Blood Glucose Control","Depression","Heat-related Symptoms","Physician Diagnosed Heat-related Illnesses","Food Insecurity","Diet Quality","Health-related Quality of Life","Indoor Thermal Comfort","Coping Ability","Life Satisfaction","Healthcare Provider Utilization","Hospitalization","Systolic Blood Pressure","Diastolic Blood Pressure","Inner Ear Canal Temperature","Dehydration","Sleep Quality","Cognition","Productivity","Aggression","Indoor Air Temperature","Indoor Relative Humidity","Indoor Heat Index","Household Energy Expenditure",[184,185,186,187,188,160,189,190,191,9,192],"Hot Temperature","Humidity","Housing","Heart rate","Cardiovascular","Mental health","Blood glucose","Diabetes","Heat Stress","2026-02-25",{"date":195,"type":196},"2026-02-27","ACTUAL",{"date":198,"type":196},"2024-09-04",{"date":200,"type":152},"2027-09-30",{"name":105,"class":6},5]
