One in six people globally is affected by loneliness, with serious health consequences including an increased risk of stroke, heart disease, diabetes, cognitive decline, and premature death, the World Health Organisation (WHO) Commission on Social Connection has warned in a report released today.

The report estimates that loneliness contributes to over 871,000 deaths annually — equivalent to more than 100 deaths every hour. In contrast, strong social ties have been associated with better health outcomes and increased life expectancy, underlining the critical role of social connection in human health.

Dr. Vivek Murthy, Co-chair of the WHO Commission and former Surgeon General of the United States, described loneliness and isolation as a “defining challenge of our time.” He emphasised the urgent need for structural reforms and a global response to mitigate its impact across sectors, from health to education and employment, according to a statement by the WHO.

While loneliness affects individuals across all age groups, adolescents and young adults have emerged as particularly vulnerable. The report notes that 17-21% of individuals aged 13-29 report experiencing loneliness, with the highest rates observed among teenagers, as per the report.
