Exploring loneliness: conceptualisation and impact in older adults

Loneliness is a pervasive and distressing emotional experience that profoundly impacts the lives of older adults. This article explores the conceptualisation of loneliness, emphasising its subjective nature and the perceived discrepancy between desired and actual social relationships. Drawing from psychological theories, loneliness is understood as an emotional response to perceived social isolation, encompassing feelings of emptiness, sadness and longing for companionship. In older adults, loneliness is exacerbated by life transitions, such as retirement and bereavement, as well as physical health limitations. The impact of loneliness on older adults' health and wellbeing is significant, with associations documented between chronic loneliness and poor mental health outcomes, including depression, anxiety and cognitive decline. Moreover, loneliness is linked to adverse physical health outcomes, such as cardiovascular disease and mortality, as well as functional decline and decreased quality of life. Recognising the multifaceted impacts of loneliness in older adults underscores the importance of developing interventions and support systems that address both the quantity and quality of social connections, promoting healthy ageing and meaningful engagement in later life.
