Loneliness and how it is slowly turning into a public health concern

Date:

Peaceloise,.a well-known content creator has described herself as 35, unmarried, childless and living alone before going ahead to show how she spends her time to avoid loneliness.The activities range from cooking, learning new skills and even a new language.

But that’s not what most Kenyans are doing on an increasingly lonely planet.

On a recent Friday evening, another Nairobi content creator Kelly Brigit posted an image on Instagram that lingered far beyond the scroll.

The photo showed a restaurant table laid for two, a glass of water half empty, cutlery arranged neatly, and one striking detail.The chair opposite her was vacant. In her caption, she admitted that even in a city full of noise and movement, she sometimes feels invisible.

The confession resonated widely, not because it was dramatic but because it was familiar. More and more young people across Kenya and the world are quietly grappling with the same hollow feeling, a loneliness that persists even amid digital connection and physical crowds.

Experts now warn that what looks like a private ache is becoming a global public-health crisis.

The World Health Organization, WHO, estimates that roughly one in six people worldwide experience loneliness, with the numbers even higher among adolescents and young adults.

In countries across Africa, the rates appear greater still, as rapid urbanisation, economic pressure and shifting social structures unravel traditional forms of community. What once felt like a Western problem has become an African one too. Kenya, with its growing cities and increasingly digital youth culture, sits squarely inside this trend. The silent emptiness in Kelly’s photo mirrors quiet scenes in many people’s lives — the solo diner waiting for company that never arrives, the young worker scrolling through chats while eating alone, the student in a crowded matatu who feels utterly disconnected. These moments may seem small, but they reflect a profound mismatch between the human need for connection and the fragmented realities of modern life.Singlehood is one of the forces complicating today’s loneliness.

Across Nairobi, Mombasa and other urban centres, more people are living alone, staying single longer or delaying long-term partnerships. Being single does not automatically lead to loneliness — many people value independence — but sociologists note that it can strip away a consistent source of companionship, conversation and everyday emotional support. Combined with the pressures of long working hours, economic precarity and constant digital distraction, singlehood can heighten vulnerability to social disconnection. The result is an environment in which individuals may have hundreds of online interactions yet feel starved of genuine presence.

Scientists and psychologists warn that loneliness should no longer be dismissed as a passing emotional state. Research links chronic loneliness to a higher risk of cardiovascular disease, stroke, diabetes, cognitive decline and early mortality.

The WHO estimates that hundreds of thousands of deaths each year are associated with loneliness and social isolation — a health risk comparable to smoking or obesity.

For young people, the effects are especially alarming. Loneliness is closely associated with rising anxiety, depression, poor sleep and reduced school or work performance. Over time, it can erode confidence, deepen self-doubt and make it more difficult to form lasting relationships. These consequences show why loneliness has shifted from a private sorrow to a societal concern.

Africa’s rapidly changing social landscape plays a significant role in this crisis. Extended families, neighbourhood bonds and communal living once buffered individuals from emotional isolation. But economic pressures push many young people into cities where they live in small apartments, work long hours and rely on digital communication for social contact. The traditional networks that once guaranteed companionship — aunties dropping by, neighbours checking in, cousins growing up together — have thinned.

In Kenya, this change is particularly visible among urban youth balancing ambition with isolation. Even those with many friends online often struggle to find consistent, emotionally present companionship offline.

Psychologists and public-health experts argue that loneliness must be treated as a collective issue, not a personal failure. They call for investment in social infrastructure: youth centres, shared community spaces, sports clubs, safe public parks and group activities that make interaction natural and frequent.

Schools can incorporate social-connection skills into their programmes; workplaces can create environments that foster interaction rather than competition. Cities can be designed with people in mind: benches, green spaces, walkable streets, community halls and affordable cafés that invite lingering rather than rushing home alone.

For individuals, the path forward does not always require grand gestures. It can mean inviting a friend to share a meal instead of eating alone, joining a local book club or volunteer group, reconnecting with neighbours, or simply choosing to spend time offline in the company of others. Even small acts of presence like a conversation, a shared walk, a moment of listening could easily counteract the quiet pull of isolation.

Yet the larger responsibility lies with societies and governments. If loneliness is as harmful as health experts warn, then strengthening social connection is not just an emotional good but a public-health necessity. Kenya’s communities have a long history of collective spirit; reviving that ethos in modern cities may be one of the most powerful tools against loneliness.

This is why the photograph posted by Kelly matters. That empty chair is more than a missed dinner companion: It is a mirror of a global condition that many feel but few articulate; It is a reminder that connection is not a luxury but a lifeline. And it is a quiet call for societies to rebuild the networks, spaces and habits that help people feel seen, valued and held.

If we pay attention to these small, silent signals, the empty seats, the quiet captions, the lonely evenings, we might rediscover the everyday acts of togetherness that keep loneliness from hardening into despair.
