Social isolation and loneliness have even been estimated to shorten a person’s life span by as many as 15 years. People who are socially isolated or lonely (SI/L) are more likely to be admitted to nursing homes and the emergency room. According to the Health Resources and Services Administration, people who are SI/L may get too little exercise and often don’t sleep well, which can increase the risk of stroke (by 32%), heart disease (by 29%), mental health disorders (by 26%) and premature mortality (by 26%), as well as other serious conditions.⁠
⁠
The University of California, San Francisco, found that being alone most of the time may contribute to a decline in the ability to perform everyday tasks. Fifty-nine percent were more likely to find daily tasks such as climbing stairs or walking more difficult.⁠

Social isolation and loneliness may also be bad for brain health and have been linked to poorer cognitive function and a higher risk for dementia (by 50%), including and especially Alzheimer’s disease. Unlike mental health disorders such as depression, social isolation, and loneliness often aren’t diagnosed. However, they still can promote negative cognitive and physical health effects—people who are lonely experience emotional pain.⁠
⁠
Losing a sense of connection and community can change the way an individual sees the world. Someone experiencing chronic loneliness can feel vulnerable and mistrustful of others. Emotional pain can activate the same stress responses in the body as physical pain. When this occurs over a long period, it can lead to chronic inflammation and reduced immunity. This raises the risk of chronic diseases.⁠
