What is social isolation?

Social isolation and loneliness are distinct but related: isolation is the objective lack of social contact, while loneliness is the subjective feeling of being alone. Both are dangerous for seniors. The National Academies of Sciences found that social isolation increases the risk of dementia by 50%, heart disease by 29%, and stroke by 32%. Over 1 in 4 adults aged 65+ are considered socially isolated. Contributing factors include living alone, loss of a spouse, reduced mobility, hearing loss, and driving cessation. Even brief daily social interactions — like a phone call — can significantly reduce the health risks associated with isolation.
