Abstract
In his 1930 essay Civilization and Its Discontents, Sigmund Freud expressed a certain sympathy for those who retreated into what he called “voluntary solitude.” 1 And yet, solitude is not always voluntary. Loneliness—a very different state—remains one of the most underrecognized and underdiscussed public health issues of our time. Despite its deeply human character, loneliness is still a taboo topic, cloaked in silence and shame.
More than half of all people have experienced loneliness at some point in their lives. This is not merely a passing emotion but a profound and often painful sense of disconnection. In modern parlance, loneliness is generally defined as the perceived gap between the social relationships we desire and those we actually have. It is the subjective experience of being alone, even when surrounded by others.
A large-scale survey conducted by a German health insurance recently found that 58% of respondents reported feeling lonely “often,” “sometimes,” or “occasionally”—with 4% feeling lonely frequently. 2 Most had never spoken to anyone about their loneliness, fearing they might burden others with their feelings. These numbers echo findings from many other parts of the world. In the United Kingdom, for example, a 2024 government report estimated that approximately 3.1 million people (7% of the population) often or always feel lonely. 3 Only 1 in 5 never felt lonely. In Japan, the issue has become so prominent that a “Minister for Loneliness” was appointed in 2021.
Contrary to popular belief, loneliness is not just an affliction of old age. In fact, younger people report higher levels of loneliness. In the German study, 68% of respondents aged 18 to 39 said they frequently, sometimes, or occasionally felt lonely, compared to just over 50% among older age groups. And younger individuals do not just experience loneliness more often—they are also more distressed by it. More than one-third of younger respondents who had experienced loneliness described it as a significant or very significant burden.
This generational paradox—being more socially connected via technology yet more isolated emotionally—deserves close attention. Perhaps most concerning are the broader implications for democratic societies. In many countries, young adults are increasingly disengaged from political and civic life: lonely young people express lower levels of interest in politics and society and lower beliefs in their own capacity to effect change—or that their concerns will be heard at all. 4 Recent research suggests that lonely individuals, particularly younger ones, may be more susceptible to authoritarian ideologies and conspiracy narratives. 4 This vulnerability—shaped not only by emotional isolation but also by a perceived lack of belonging—can contribute to political radicalization and social fragmentation. The psychological need for connection and meaning is powerful; if unmet, it can be co-opted by populist or extremist movements.
But what, then, can be done?
The path out of loneliness is rarely simple, but there are known strategies that help. Maintaining regular contact with family and friends—even a phone call or text message—can reduce the emotional burden of loneliness. Engaging in community activities, whether through clubs, courses, or volunteer work, provides opportunities to foster new relationships. Simple practices like taking walks, pursuing hobbies, or engaging in sports can enhance well-being and facilitate informal social encounters. These interventions are low-cost but potentially high-impact.
Governments are beginning to take the issue seriously. In 2023, the U.S. Surgeon General released a landmark advisory declaring loneliness and isolation an “epidemic” and proposing a national strategy for social connection. 5 In May this year, Germany’s Federal Ministry for Family Affairs launched a nationwide initiative, “Weeks of action against Loneliness.” This effort builds on earlier strategies developed under previous administrations and aligns with similar policies in other countries. The aim is not only to raise awareness but also to support targeted research—especially on loneliness among children and adolescents—and to develop evidence-based interventions. The World Health Organization has also begun to prioritize social isolation and loneliness as key determinants of health, linking them to increased risks for cardiovascular disease, depression, dementia, and even premature death. 6
In the context of integrative and complementary medicine, the topic of loneliness deserves particular attention. Our field, which places strong emphasis on whole-person care, is uniquely positioned to address the social and emotional dimensions of health. Practitioners of integrative care often cultivate therapeutic relationships that go beyond clinical transactions. These relationships can act as anchors for individuals adrift in a sea of disconnection.
Moreover, integrative health models frequently include group-based interventions—such as yoga classes, support circles, or meditation workshops—that create spaces for human connection. In these settings, healing does not happen in isolation but in community. Recognizing and strengthening these dimensions can be a powerful complement to biomedical and public health responses.
Ultimately, addressing loneliness requires a cultural shift. It means creating a world where asking for connection is not seen as weakness but as wisdom. Where social bonds are nurtured with the same urgency as economic growth or technological advancement. Where health includes not only the absence of disease but also the presence of meaningful relationships.
To quote a famous Zulu proverb: “A person is a person through other persons.” If we are to build a healthier and more humane future, we must begin by honoring that truth—not only in policy and research, but in how we live, work, and care.
