Health advice often focuses on what people eat, how much they move and whether they get enough sleep. A 2025 report from the World Health Organization adds another part of the picture: whether people feel connected to one another, and whether they have support when they need it.
The report, prepared by the WHO Commission on Social Connection, describes connection as a public health issue—not simply a matter of personality or private preference. Its central message is that relationships can support well-being, while loneliness and social isolation are associated with significant health risks. Just as importantly, the conditions that make connection possible are shaped by communities and public services, not only by individual effort.
Loneliness and isolation are related, but not identical
Social isolation generally refers to having few social contacts or limited interaction. Loneliness is the distressing feeling that one’s relationships do not provide the connection a person wants. Someone can live alone and feel content, or be surrounded by people and still feel lonely. The distinction matters: counting contacts cannot fully measure whether a person feels understood, included or supported.
The WHO report estimates that about one in six people worldwide experience loneliness. It also says loneliness is associated with an estimated 871,000 deaths each year—roughly 100 an hour. These figures describe associations, not a claim that loneliness alone causes each death. Health is influenced by many intersecting factors, and research on social connection cannot make every link a simple cause-and-effect story.
Still, the pattern is important. The WHO identifies links between loneliness and conditions including depression, anxiety, cardiovascular disease and stroke. Social connection, in turn, can offer emotional and practical support and help people cope with stress. The U.S. Surgeon General’s 2023 advisory likewise reviews evidence connecting social connection with health and well-being, while emphasizing that the effects extend beyond feeling happy or having an active social calendar.
Why relationships may matter to health
Connection can influence everyday health in several ways. A trusted person may notice when someone is struggling, help them seek care, or make it easier to follow a treatment plan. Shared activities can create routine and give people reasons to leave home. Feeling supported may also affect how people manage stress. These are plausible pathways, but they do not mean that a friendship is a substitute for medical care or that every health outcome can be explained by someone’s social life.
Researchers have studied the relationship between social ties and mortality for decades. A widely cited 2010 meta-analysis by Julianne Holt-Lunstad and colleagues combined results from 148 studies and found that stronger social relationships were associated with a greater likelihood of survival. The authors noted that social relationships are a significant predictor in population research; the finding does not guarantee an outcome for any one person. The WHO commission’s contribution is to put this broad evidence into a global policy discussion.
That discussion also asks who has a fair chance to connect. Disability, discrimination, poverty, migration, bereavement, language barriers and inaccessible public spaces can all make participation harder. So can a lack of affordable transport or places to gather. Telling a lonely person simply to “reach out” may overlook the obstacles that make reaching out difficult.
Making connection easier, not prescribing a social life
The WHO report calls for action at multiple levels. Governments and local organizations can consider whether public spaces, transport, community programs and digital access help people take part in everyday life. Schools and workplaces can foster a sense of inclusion. Health and social-care providers can pay attention to isolation as part of a broader understanding of a person’s circumstances.
None of this requires treating a particular lifestyle as the ideal. People differ in how much social contact they want, and meaningful connection can take many forms: a regular conversation with a neighbor, a faith or cultural community, time with family, a hobby group, or a supportive relationship with a health or care worker. The goal is not to prescribe a certain number of friends. It is to make it easier for people to find the kinds of relationships and participation that work for them.
For an individual who wants more connection, modest steps may be more manageable than a sweeping plan: reply to someone who has reached out, make a recurring appointment for a shared activity, or ask a trusted person for company during an ordinary task. Community centers, libraries and local organizations may offer low-pressure ways to participate. These are possibilities, not guaranteed treatments, and a person should not be blamed if circumstances make connection difficult.
Persistent loneliness can be painful, and it may occur alongside depression, anxiety or other health concerns. A clinician or mental health professional can help assess what is going on and discuss appropriate support. Seeking help is not an admission of personal failure.
The WHO commission’s broader point is that connection should not be left entirely to chance. Relationships are personal, but the opportunities to form and maintain them are partly public. If communities are designed so people can meet, participate and get support, connection becomes more than a private virtue: it becomes one part of a healthier environment.
