Background: Cognitive functioning and performance are important aspects of health and wellbeing in older adults. Previous studies in labs and through population-level epidemiology have identified a link between ambient temperature and cognitive performance and functioning in older adults. This study is among the initial attempts to employ smart sensors and smartphone surveys for prolonged, at-home monitoring of environmental conditions and cognitive abilities in older adults. Methods: In this longitudinal observational study, we continuously measured the ambient temperature in the homes of a group of older individuals in Boston, MA (n=47) for 18 months, while the completed daily surveys of attention. Results: Our findings indicate a U-shaped relationship between the temperature in the home at the time of evaluation and the likelihood of experiencing difficulty keeping attention. The likelihood was lowest in temperatures ranging from 20 – 24 ˚C and increased by twofold when deviating by 4 ˚C from this range in either direction. Discussions: Anticipated changes in climate are expected to alter global weather patterns, leading to more frequent and severe extreme weather events. At the same time, many older adults, due to poverty or diminished physical or cognitive capabilities, cannot maintain an ideal temperature in their homes. This research sheds light on an additional way climate change could affect the health and wellness of older adults, underscoring the urgency for public health interventions, housing policy reforms, and healthcare strategies to enhance their resilience.
