Loneliness is a silent epidemic affecting millions worldwide, with profound implications for mental and physical health. The World Health Organization (WHO) recently highlighted that 1 in 6 people globally experiences loneliness, leading to significant health risks and economic costs.
The Global Loneliness Crisis: A Wake-Up Call
The WHO Commission on Social Connection’s 2025 global report, released in June 2025 reveals that loneliness affects 17–21% of individuals aged 13–29, with teenagers reporting the highest rates. In low-income countries, 24% of people feel lonely, compared to 11% in high-income countries.
According to the report by Next Move Strategy Consulting, the global Mental Health Technology Market size is projected to grow, hitting USD 30.97 billion by 2030, with a CAGR of 19% between 2025 and 2030.
Loneliness is not just a feeling—it’s a public health issue, contributing to an estimated 871,000 deaths annually, or 100 deaths per hour.
Social isolation, defined as an objective lack of sufficient social connections, affects up to 1 in 3 older adults and 1 in 4 adolescents. Groups like refugees, LGBTQ+ individuals, and people with disabilities face additional barriers due to discrimination, exacerbating their isolation.
Key Data Points:
- 17–21% of youth (13–29 years) report loneliness.
- 24% of people in low-income countries feel lonely, versus 11% in high-income countries.
Loneliness and social isolation are widespread, affecting diverse populations and driving the need for innovative mental health solutions.

Why Social Connection Matters for Health?
Social connection—the ways people interact and relate to others—has a profound impact on health. Strong social bonds can reduce inflammation, lower risks of chronic diseases like heart disease and diabetes, and even prevent early death. Conversely, loneliness increases the risk of stroke, cognitive decline, and mental health issues, with lonely individuals being twice as likely to experience depression.
Beyond health, social connection influences education and employment. Teenagers who feel lonely are 22% more likely to achieve lower grades, while adults face challenges in maintaining employment or earning potential.
Health Impacts of Social Connection:
- Reduces inflammation and chronic disease risk.
- Lowers likelihood of depression, anxiety, and suicidal thoughts.
- Enhances community resilience and safety.
Social connection is a protective factor for mental and physical health, making it a critical focus for mental health technology innovations.
Mental Health Technology: Bridging the Connection Gap
The rise of loneliness presents challenges that various sectors are addressing. Digital technologies can contribute to loneliness and the report stresses the need for vigilance around excessive screen time and negative online interactions that can worsen mental health, particularly among young people.
The WHO’s primary recommendations focus on strengthening social infrastructure (such as parks, libraries, and cafés), implementing evidence-based policies, and providing direct psychological interventions. The report calls for solutions at multiple levels—national, community, and individual—ranging from raising awareness and changing national policies to providing community-based support.
While the mental health technology sector sees opportunities to address the 1 in 6 people affected by loneliness, any technological approaches must be carefully designed to promote genuine human connection rather than replacing it. This market perspective drives innovation in telehealth and digital wellness platforms, though these represent industry responses rather than WHO’s primary recommended interventions.
How Technology Can Combat Loneliness?
The report outlines evidence-based solutions that exist at multiple levels to reduce loneliness and social isolation:
National Level:
- Policy development and implementation to promote social connection
- Raising public awareness about loneliness as a public health issue
- Developing national strategies for social connection
Community Level:
- Strengthening social infrastructure (parks, libraries, cafés, community centers)
- Creating inclusive spaces that welcome diverse populations
- Supporting community programs and local organizations
Individual Level:
- Psychological interventions for those experiencing severe loneliness
- Simple everyday actions like reaching out to friends, joining local groups, or volunteering
- Accessing available support services when needed
Technology Considerations: Some digital platforms may offer support (such as access to mental health services), caution is needed as excessive screen time and negative online interactions can worsen mental health. Any technology-based approaches should complement, not replace, real-world social connections and must be designed to promote genuine human connection.
The Economic and Social Stakes
Loneliness doesn’t just affect individuals—it has broader societal and economic consequences. Communities with strong social bonds are safer, healthier, and more resilient, while loneliness undermines social cohesion and costs billions in healthcare and lost productivity. For example, lonely adults face employment challenges, reducing earning potential and economic output.
While the mental health technology market is exploring solutions, the report emphasizes that addressing loneliness through evidence-based interventions—including policy changes, social infrastructure improvements, and community programs—can improve health outcomes and reduce the economic burden on healthcare systems and employers.
Economic Impacts:
- Loneliness costs billions in healthcare and productivity losses.
- Socially connected communities are more resilient to disasters.
The economic and social benefits of addressing loneliness through technology are significant, driving investment in mental health solutions.
Next Steps: Actionable Takeaways for Individuals and Organizations
Here are practical steps to take:
- Leverage Technology Wisely: Use apps or platforms that promote meaningful connections, such as virtual support groups or telehealth services, to combat loneliness.
- Engage in Community Activities: Join local groups, volunteer, or participate in community events to build real-world connections.
- Advocate for Policy Changes: Support policies that enhance social infrastructure, like funding for parks or libraries, to foster community engagement.
- Monitor Screen Time: Limit excessive digital use to avoid negative mental health impacts, and prioritize face-to-face interactions when possible.
Final Thought
Social connection is a public health priority. By integrating technology with intentional community-building, we can reduce loneliness, improve health outcomes, and drive growth in the mental health technology market. Let’s take these insights and turn them into action for a more connected, healthier world.
