How does loneliness affect health?

This evidence brief examines the extensive research on how loneliness negatively affects health, highlighting that social disconnection is linked to a variety of adverse health outcomes, including cardiovascular disease, cancer, diabetes, mental health disorders, and even premature death. The brief traces the historical context of loneliness research, noting that while awareness of its effects has existed for over a century, significant scientific exploration began in the 1970s. Recent studies have demonstrated that the health risks associated with loneliness are comparable to well-known risk factors such as obesity, smoking, and high blood pressure.

The brief explores four primary mechanisms by which loneliness impacts health: co-occurring characteristics and conditions, differential access to care, unhealthy behaviors, and dysregulation of stress responses. It discusses how loneliness often coexists with other factors like disabilities or low income, which can contribute to poor health. Additionally, lonely individuals may face barriers to healthcare access and engage in unhealthy behaviors such as poor diet, substance abuse, and physical inactivity. The dysregulation of stress responses due to chronic loneliness can lead to widespread physiological harm. Analyses from the Canadian Social Connection Survey support these findings, emphasizing the need for policies and programs to address loneliness and its health consequences.
