Prolonged loneliness is increasingly being recognized as a serious threat to public health, with chronic feelings of isolation potentially triggering long-term stress responses that affect both physical and mental well-being.
Clinical Psychologist Cansu Kaya of Medicana Camlica Hospital spoke to Anadolu Agency about the risks associated with prolonged loneliness, noting that its effects can be comparable to major health risk factors such as smoking, obesity, and physical inactivity.
Recent data shows that the number of individuals living alone in Türkiye has surpassed 5.5 million, representing an approximate 66% increase over the past decade.
Rising individualism, economic pressures, later marriage age, and the fast-paced dynamics of metropolitan life have made living alone both a visible social phenomenon and a growing public health concern.
Kaya noted that living alone does not necessarily equate to feeling lonely, stating that “individuals may experience loneliness even in crowded environments.”
Prolonged loneliness activates a continuous stress mechanism in the body, increasing the risk of cardiovascular diseases, weakening the immune system, and elevating stroke risk. It may also contribute to sleep disturbances, metabolic imbalances, and heightened inflammation levels.
Beyond physical health, prolonged loneliness has been linked to depression, anxiety, diminished self-esteem, cognitive decline, and a higher dementia risk.
Individuals experiencing loneliness are also more likely to adopt sedentary lifestyles, unhealthy dietary habits, and addictive behaviors.
Kaya recommended measures such as strengthening community and neighborhood networks, reducing social isolation among the elderly, encouraging in-person social interactions for young people, and improving access to psychological support services.
