Effect of Climate Change on Health in Older Persons

Abstract

On a global scale, the population aged 65 and over is the fastest growing age group. By the year 2050, one in six people will be aged over 65 years, compared to only one in eleven during 2019. The adverse effects of climate change have a broad range of negative impacts on human health and psychosocial status. For the vulnerable ageing population, often limited by their physical, cognitive, psychosocial conditions and economic resources, the effects of climate change can be exceptionally challenging. Compounded by pre-existing medical conditions, immunosenescence, and the presence of various geriatric syndromes, the older persons find themselves at risk of disease exacerbation when exposed to climate-related stressors compared to younger adults. This review is aimed at exploring various aspects of climate change and its impact on older persons’ health.
