Britain faces a ‘major public health challenge’ caused by the impact of long-term loneliness on elderly people, two charities have warned. Entitled ‘Promising approaches to reducing loneliness and isolation in later life’, the report details the impact of chronic loneliness – feeling lonely all or most of the time – can have on the health of older people. The research uncovered that one in four (2.9million) Britons aged 65 and over feel they have no one to go to for help and support. As well as serious implications for mental health, it found that chronic loneliness can be as harmful as smoking, increasing the risk of dementia, high blood pressure and depression. The report claims that health service funders and commissioners are suffering from a 'knowledge gap' as they struggle to meet the growing challenge of chronic loneliness. Laura Alcock-Ferguson, director of the Campaign to End Loneliness, said the framework is being offered to those councils which wish to use it.
