Loneliness has become a critical concern for public health, as the 2023 US Surgeon General recently announced it as an epidemic in its own right. As regional representatives, we commend the declaration for emphasizing the gravity of the crisis. In fact, research indicates that loneliness is as deadly as smoking 15 cigarettes a day. The negative effect of social isolation, both physical and mental, is severe. In response, countries including Japan and the United Kingdom have designated a “Minister of Loneliness” to address this burgeoning epidemic. On an international level, programs are being introduced to fight social isolation and encourage community engagement.
As a rebuttal to this epidemic, the 2023 Surgeon General’s Advisory detailed six pillars that can help build strong social connections. These pillars include enhancing social infrastructure in local communities, enacting pro-connection policies, engaging the health sector, reforming digital environments, advancing research, and fostering a culture of connection. Perhaps the most striking finding came from a massive meta-analysis coauthored by Julianne Holt-Lunstad. Providing psychosocial support in clinical care increases the chances of survival by 20%. The World Health Organization (WHO) has responded by creating a Commission on Social Connection. This commission looks to develop a global agenda to address the epidemic of social disconnection.
Understanding the Loneliness Epidemic
With the Surgeon General’s declaration of loneliness as an epidemic, the focus is on the broad reach it has across society. Health impacts of loneliness have been found to be as serious as smoking 15 cigarettes a day. A large body of research indicates that it has great potential to damage brain and body health. Quoting Julianne Holt-Lunstad, PhD, when she said, “Loneliness is only one aspect of not having enough connection,” stressed the concept that social isolation comes in many different forms.
In early 2024, Japan passed the Act on Promotion of Policy for Loneliness and Isolation. This law was a big policy breakthrough on these important social determinants of health. The United Kingdom even named a “Minister of Loneliness” to lead the charge against social isolation. The United Kingdom has gone even further, appointing its own “Minister of Loneliness.” This decision in itself is significant, as it acknowledges the global recognition of the problem.
Paul Appelbaum, MD, cited the rising rates of loneliness in adolescents as yet another reason to worry. He noted that there’s a wealth of data backing up the change in socialization that people are seeking. This is one of the major shifts impacting not just adults, but adolescents in our society today. This change in social dynamics only adds to the climate as younger generations are increasingly challenged to build enduring relationships.
Strategies for Fostering Social Connection
The six pillars detailed by the Surgeon General offer an encouraging and robust foundation for tackling loneliness. Improving social infrastructure on the local level is an important step towards establishing communities where people can interact in a more genuine way. Pro-connection policies are necessary, not just to support these kinds of initiatives but to help them endure long-term.
The next crucial step is to engage the health sector. Through incorporating psychosocial support into the clinic, healthcare professionals can have a profound impact on patient outcomes and survivability. Paul Appelbaum emphasized the importance of respecting individual agency in these interventions, stating, “People get to run their own lives. Clinicians can certainly suggest changes in a gentle way that address problems.”
That’s why reforming digital environments is so important now, when technology more than ever affects how we interact socially. Advancing quality research into loneliness and its effects will help us craft evidence-based interventions. Ellen E. Lee, MD, pointed out that “neurology-based loneliness research is still in its infancy,” indicating room for growth in understanding brain mechanisms involved in social connection.
Community-Based Approaches and Global Initiatives
Community-based projects such as Sweden’s SällBo initiative are examples of creative approaches to fighting loneliness. SällBo intentionally mixes these residents of different cultures and localities, and different generations. By animating their streets with fun, popular shared experiences, they build social capital and community ties. These projects underscore the impact local efforts can have on worldwide problems.
The WHO’s new Commission on Social Connection intends to create a global agenda for action. Their work is all about making the case for intervention, rallying support to scale up solutions that have already proven successful, and measuring progress to ensure success. Julianne Holt-Lunstad expressed cautious optimism about these efforts: “We still have a long way to go. We have made some headway in terms of a national measurement.”
Social prescribing is another method that’s being experimented with, though research on its effectiveness is still in progress. This model relies on healthcare providers prescribing social engagement opportunities to enhance patient quality of life. Though promising, more studies are required to assess the overall effect.
