Exhaustion

Older adults are generally among the most vulnerable to heat and cold. While temperature-related health impacts are projected to increase with global warming, the influence of population ageing on these trends remains unclear. Our findings indicate that population ageing constitutes a crucial driver for future heat- and cold-related deaths, with increasing mortality burden for both heat and cold due to the ageing population.

Climate change can directly impact temperature-related excess deaths and might subsequently change the seasonal variation in mortality. In this study, we aimed to provide a systematic and comprehensive assessment of potential future changes in the seasonal variation, or seasonality, of mortality across different climate zones.

As the climate warms, increasing heat-related health risks are expected, and can be exacerbated by the urban heat island (UHI) effect. UHIs can also offer protection against cold weather, but a clear quantification of their impacts on human health across diverse cities and seasons is still being explored. Here we provide a 500 m resolution assessment of mortality risks associated with UHIs for 85 European cities in 2015-2017. The findings urge strategies aimed at designing healthier cities to consider the seasonality of UHI impacts and to account for social costs, their controlling factors, and intra-urban variability.

BACKGROUND AND AIM: In this study, we aim to gauge the impact of temperature fluctuations on productivity loss in Norway by examining the relationship between past temperature and sick leave. METHOD: We conducted our analysis using a panel dataset in the year 2018 for individual-location-specific daily temperatures and sick leave records from a national registry in Norway based on the Cohort of Norway (CONOR). RESULTS: Our findings suggest that temperature fluctuations had significant impacts on health and productivity, and these effects varied depending on the season and personal characteristics.

There is limited evidence of temporal changes in the association between air temperature and the risk of cause-specific cardiovascular [CVD] and respiratory [RD] mortality. We analysed a total of 3,159,292 non-accidental, 1,063,198 CVD and 183,027 RD deaths. We found evidence of rising population susceptibility to both heat- and cold-related CVD and RD mortality risk from 1993 to 2016. Climate change mitigation and targeted adaptation strategies might help to reduce the number of temperature-related deaths in the future.

Existing studies on the association between temperatures and cardiovascular deaths have been limited in geographic zones and have generally considered associations with total cardiovascular deaths rather than cause-specific cardiovascular deaths. Across a large, multinational sample, exposure to extreme hot and cold temperatures was associated with a greater risk of mortality from multiple common cardiovascular conditions. The intersections between extreme temperatures and cardiovascular health need to be thoroughly characterized in the present day—and especially under a changing climate.
