7. Any URL or additional information regarding plan/policy for sharing IPD? 
   Additional Information - Data that can be shared unconditionally underpinning the published research articles will be made available to other researchers at the time of publication, and data will be linked via the article DOI. Data that cannot be unconditionally shared upon publication owing to confidentiality or data protection requirements will be identified as such and a contact email will be provided in relevant publications for data access enquiries by other researchers. Individual names of study participants and identifying factors will be removed prior to data sharing. It is expected that the demographic data of people at the study sites (family size and composition, basic socioeconomic indicators) may contain personally identifiable information and location data. All such data will be removed prior to sto

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.
