A recent report from a WHO Commission emphasizes the importance of strong social ties for maintaining good health, warning that loneliness and social isolation are significant global health threats.

It is estimated that loneliness contributes to 871,000 additional deaths each year across 100 countries, with risks akin to smoking 15 cigarettes daily.

Social isolation increases the likelihood of heart disease, stroke, dementia, anxiety, and depression.

The Commission urges immediate, multi-sectoral efforts, such as enhancing community infrastructure, formulating supportive policies  and incorporating social connection into healthcare systems.

The report from the WHO Commission on Social Connection presents a worldwide action plan that concentrates on five main areas: policy, research, interventions, improved measurement (including the creation of a global Social Connection Index) and public engagement. 

The aim is to transform social norms and strengthen a global movement for social connection.

Additionally, WHO introduced the “Knot Alone” campaign and passed its first World Health Assembly resolution on social connection in June 2025, urging nations to prioritize this issue. 

Tackling social isolation is crucial for enhancing population health and reducing premature mortality worldwide.
