简要总结
Increasing heat exposure from climate change is causing and exacerbating heat-related illnesses in millions worldwide – particularly in low resource settings. Ambient air temperatures in India have broken record highs in 2024. Heat exposure can instigate and worsen numerous health conditions. Adaptation is essential for protecting people from increasing heat exposure. The built environment, especially homes, are ideal for deploying interventions to reduce heat exposure and accelerate adaptation efforts. However, evidence is currently lacking in India – generated through empirical studies – guiding the uptake of interventions to reduce indoor heat stress in vulnerable communities.
Sunlight-reflecting cool roof coatings passively reduce indoor temperatures and lower energy use, offering protection to home occupants from extreme heat. Continuous monitoring of health and wellbeing using smartwatches can provide insight into important parameters such as heart rate, sleep and physical activity – which are all affected by heat. Using smartwatches, the investigators will also continuously measure health and wellbeing outcomes during the day and night. The investigators will investigate the effects of cool-roof use on heart rate, sleep and physical activity in Ahmedabad, India.
This trial will quantify whether cool roofs are an effective passive home cooling intervention with beneficial health effects for vulnerable populations in Ahmedabad. Findings will inform local policy responses on scaling cool roof implementation to protect people from increasing heat exposure driven by climate change.
