ChroniC loneliness is associated with an increased risk of physical health issues such as dementia, heart disease, and stroke, all of which can wear on the body and mind in ways similar to aging. Loneliness is also linked to an increased risk of depression and anxiety.
Elderly people are at a higher risk of feeling lonely, because they are more likely to live by themselves or have a chronic illness or disability that makes participating in some social activities more difficult. The complications associated with social isolation often exacerbate and intensify the health complications older adults already experience.
Research also suggests that those who are socially active and partake in social activities tend to live longer and have better cognitive function as they age.
