The World Health Organization (WHO) Commission on Social Connection has released its global report revealing that 1 in 6 people worldwide is affected by loneliness, with significant impacts on health and well-being. Loneliness is linked to an estimated 100 deaths every hour—more than 871 000 deaths annually. Strong social connections can lead to better health and longer life, the report says.

“In this Report, we pull back the curtain on loneliness and isolation as a defining challenge of our time. Our Commission lays out a road map for how we can build more connected lives and underscores the profound impact this can have on health, educational, and economic outcomes,” said Dr Vivek Murthy, Co-chair of the WHO Commission on Social Connection, and former Surgeon General of the United States of America.

WHO defines social connection as the ways people relate to and interact with others. Loneliness is described as the painful feeling that arises from a gap between desired and actual social connections, while social isolation refers to the objective lack of sufficient social connections.

“In this age when the possibilities to connect are endless, more and more people are finding themselves isolated and lonely," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "Apart from the toll it takes on individuals, families and communities, left unaddressed, loneliness and social isolation will continue to cost society billions in terms of health care, education, and employment. I welcome the Commission's report, which shines a light on the scale and impact of loneliness and isolation, and outlines key areas in which we can help people to reconnect in ways that matter most.”

Scale and causes of loneliness and social isolation

Loneliness affects people of all ages, especially youth and people living in low- and middle-income countries (LMIC). Between 17–21% of individuals aged 13–29-year-olds reported feeling lonely, with the highest rates among teenagers. About 24% of people in low-income countries reported feeling lonely — twice the rate in high-income countries (about 11%).

“Even in a digitally connected world, many young people feel alone. As technology reshapes our lives, we must ensure it strengthens—not weakens—human connection. Our report shows that social connection must be integrated into all policies—from digital access to health, education, and employment,” said Chido Mpemba, Co-chair of the WHO Commission on Social Connection and Advisor to the African Union Chairperson. 

While data on social isolation is more limited, it is estimated to affect up to 1 in 3 older adults and 1 in 4 adolescents. Some groups, such as people with disabilities, refugees or migrants, LGBTQ+ individuals, and indigenous groups and ethnic minorities, may face discrimination or additional barriers that make social connection harder.

Loneliness and social isolation have multiple causes. They include, for instance, poor health, low income and education, living alone, inadequate community infrastructure and public policies, and digital technologies. The report underscores the need for vigilance around the effects of excessive screen time or negative online interactions on the mental health and well-being of young people.  

Impacts on health, quality of life and economies

Social connection can protect health across the lifespan. It can reduce inflammation, lower the risk of serious health problems, foster mental health, and prevent early death. It can also strengthen the social fabric, contributing to making communities healthier, safer and more prosperous. 

In contrast, loneliness and social isolation increase the risk of stroke, heart disease, diabetes, cognitive decline, and premature death. It also affects mental health, with people who are lonely twice as likely to get depressed. Loneliness can also lead to anxiety, and thoughts of self-harm or suicide.

The impacts extend to learning and employment. Teenagers who felt lonely were 22% more likely to get lower grades or qualifications. Adults who are lonely may find it harder to find or maintain employment and may earn less over time.

At a community level, loneliness undermines social cohesion and costs billions in lost productivity and health care. Communities with strong social bonds tend to be safer, healthier and more resilient, including in response to disasters.

A path to healthier societies

The report of the WHO Commission on Social Connection outlines a roadmap for global action focusing on five key areas: policy, research, interventions, improved measurement (including developing a global Social Connection Index), and public engagement, to shift social norms and bolster a global movement for social connection.

Solutions to reduce loneliness and social isolation exist at multiple levels – national, community and individual – and range from raising awareness and changing national policies to strengthening social infrastructure (e.g., parks, libraries, cafés) and providing psychological interventions.

Most people know what it feels like to be lonely. And each person can make a difference through simple, everyday steps—like reaching out to a friend in need, putting away one’s phone to be fully present in conversation, greeting a neighbor, joining a local group, or volunteering. If the problem is more serious, finding out about available support and services for people who feel lonely is important.

The costs of social isolation and loneliness are high, but the benefits of social connection are far-reaching.

With the release of the Commission report, WHO calls on all Member States, communities and individuals to make social connection a public health priority.

Editor’s notes 

The report launch follows the first-ever resolution on social connection, adopted by the World Health Assembly (WHA) in May 2025, which urges Member States to develop and implement evidence-based policies, programmes and strategies to raise awareness and promote positive social connection for mental and physical health. At the WHA, WHO also announced a new campaign called “ Knot Alone” to promote social connection for better health. Tune in to WHO’s social media channels to follow the campaign.  

As part of its broader efforts, WHO has also launched the Social Connection Series to explore the lived experience of loneliness and social isolation. Learn more about the series here.

 

The WHO Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), a panel of 27 independent, international, multidisciplinary experts, today published its report on the origins of SARS-CoV-2, the virus responsible for the COVID-19 pandemic.

Tracking SDG 7: The Energy Progress Report 2025 finds that almost 92% of the world’s population now has basic access to electricity. Although this is an improvement since 2022, which saw the number of people without basic access decrease for the first time in a decade, over 666 million people remain without access, indicating that the current rate is insufficient to reach universal access by 2030. Clean cooking access is progressing but below the rates of progress seen in the 2010s, as efforts remain hobbled by setbacks during the Covid-19 pandemic, following energy price shocks, and debt crises.

Released today, the latest edition of the annual report that tracks progress towards Sustainable Development Goal (SDG) 7 highlights the role of distributed renewable energy (a combination of mini-grid and off-grid solar systems) to accelerate access, since the population remaining unconnected lives mostly in remote, lower-income, and fragile areas. Cost-effective and rapidly scalable, decentralised solutions are able to reach communities in such rural areas.

Decentralised solutions are also needed to increase access to clean cooking. With an estimated 1.5 billion people residing in rural areas still lacking access to clean cooking, the use of off-grid clean technologies, such as household biogas plants and mini-grids that facilitate electric cooking, can provide solutions that reduce health impacts caused by household air pollution. Over 670 million people remain without electricity access, and over 2 billion people remain dependent on polluting and hazardous fuels such as firewood and charcoal for their cooking needs.

Notable progress was made in different indicators. The international financial flows to developing countries in support of clean energy grew for the third year in a row to reach US$ 21.6 billion in 2023. Installed renewables capacity per capita continued to increase year-on-year to reach a new high of 341 watts per capita in developing countries, up from 155 watts in 2015.

Yet regional disparities persist, indicating that particular support is needed for developing regions. In sub-Saharan Africa – which lags behind across most indicators – renewables deployment has rapidly expanded but remains limited to 40 watts of installed capacity per capita on average which is only one-eighth of the average of other developing countries. Eighty-five percent of the global population without electricity access reside in the region, while four in five families are without access to clean cooking. And the number of people without clean cooking access in the region continues to grow at a rate of 14 million people yearly.

The report identified the lack of sufficient and affordable financing as a key reason for regional inequalities and slow progress. To build on the achievements to date and avoid any further regressions on access to electricity and clean cooking due to looming risks in global markets, the report calls for strengthened international cooperation of public and private sectors, to scale up financial support for developing countries, especially in sub-Saharan Africa. Urgent actions include reforms in multilateral and bilateral lending to expand the availability of public capital; more concessional finance mobilisation, grants, and risk mitigation instruments; improvement in risk tolerance among donors; as well as appropriate national energy planning and regulations.

Key findings across primary indicators

• Almost 92% of the world’s population now has access to electricity, leaving over 666 million people without electricity in 2023, with around 310 million people gaining access since 2015. Eighteen of the 20 countries with the largest electricity access deficits in 2023 were in sub-Saharan Africa. The greatest growth in access between 2020 and 2023 occurred in Central and Southern Asia, with both regions making significant strides towards universal electricity access, reducing their basic access gap from 414 million in 2010 to just 27 million in 2023.
   
• Little to no change was observed in access to clean fuels and technologies for cooking between 2022 and 2023. Although the number of the world’s population with access to clean cooking fuels and technologies increased from 64% in 2015 to 74% in 2023, around 2.1 billion people remain dependent on polluting fuels and technologies. If current trends continue, only 78% of the global population will have access to clean cooking by 2030.
   
• In 2022, the global share of renewable energy sources in total final energy consumption (TFEC) was 17.9% as TFEC continued to increase gradually, while installed renewable energy capacity reached 478 watts per capita in 2023, indicating almost 13% growth from 2022. But progress is not sufficient to meet international climate and sustainable development goals. In addition, global efforts must address significant disparities. Despite progress in expanding renewable capacity, least developed countries and sub-Saharan Africa had only 40 watts per capita in installed renewables capacity, compared to developed countries which had over 1100 watts installed.
   
• Global energy efficiency experienced sluggish progress in recent years. The global trend shows that primary energy intensity, defined as the ratio of total energy supply to gross domestic product, declined by 2.1% in 2022. Although it is an improvement of more than four times the weak 0.5% improvement rate of 2021, it is insufficient to meet the original SDG 7.3 target. Going forward, energy intensity needs to improve by 4% per year on average.
   
• International public financial flows to developing countries in support of clean energy increased by 27% from 2022, reaching US$ 21.6 billion in 2023. However, the report reveals that the developing world received fewer flows in 2023 than in 2016, when commitments peaked at US$ 28.4 billion. Despite gradual diversification, funding remained concentrated, with only two sub-Saharan African countries in the top five recipients. Debt-based instruments drove most of the increase in international public flows in 2023, accounting for 83% in 2023, while grants made up only 9.8% of flows.

The report will be presented to decision-makers at a special launch event on 16 July 2025 at the High-Level Political Forum on Sustainable Development in New York, which oversees progress on the SDGs.

Quotes

Fatih Birol, Executive Director, International Energy Agency

“Despite progress in some parts of the world, the expansion of electricity and clean cooking access remains disappointingly slow, especially in Africa. This is contributing to millions of premature deaths each year linked to smoke inhalation, and is holding back development and education opportunities. Greater investment in clean cooking and electricity supply is urgently required, including support to reduce the cost of capital for projects.”

Francesco La Camera, Director-General, International Renewable Energy Agency

“Renewables have seen record growth in recent years, reminding the world of its affordability, scalability, and its role in further reducing energy poverty. But we must accelerate progress at this crunch time. This means overcoming challenges, which include infrastructure gaps. The lack of progress, especially on infrastructure, is a reflection of limited access to financing. Although international financial flows to developing countries in support of clean energy grew to US$ 21.6 billion in 2023, only two regions in the world have seen real progress in the financial flows. To close the access and infrastructure gaps, we need strengthened international cooperation to scale up affordable financing and impact–driven capital for the least developed and developing countries.”

Stefan Schweinfest, Director, United Nations Statistics Division

“This year’s report shows that now is the time to come together to build on existing achievements and scale up our efforts. Despite advancements in increasing renewables-based electricity, which now makes up almost 30 percent of global electricity consumption, the use of renewables for other energy-related purposes remains stagnant. While energy intensity improved in 2022, overall progress remains weak, threatening economic growth and the energy efficiency goals agreed upon at COP28. The clock is ticking. The findings of this year’s report should serve as a rallying point, to rapidly mobilize efforts and investments, so that together, we ensure sustainable energy for all by 2030.”

Guangzhe Chen, Vice President for Infrastructure, World Bank

"As we approach the five-year mark to achieve the SDG7 targets, it is imperative to accelerate the deployment of electricity connections, especially in Sub-Saharan Africa, where 85% of the 666 million people lacking access reside. As part of the Mission 300 movement, 12 African nations have launched national energy compacts, in which they commit to substantial reforms to lower costs of generation and transmission, and scale up distributed renewable energy solutions. Initiatives such as this unite governments, the private sector, and development partners in a collaborative effort.

Dr Tedros Adhanom Ghebreyesus, WHO Director-General, World Health Organization

“The same pollutants that are poisoning our planet are also poisoning people, contributing to millions of deaths each year from cardiovascular and respiratory diseases, particularly among the most vulnerable, including women and children," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "We urgently need scaled-up action and investment in clean cooking solutions to protect the health of both people and planet—now and in the future.”
