The Mental Health and Loneliness Epidemic
Around the world and in the United States, loneliness and mental illness are reaching record levels. This page shares the latest evidence-based research — and what we can do together.

The Global Picture
The World Health Organization says about 1 in 8 people around the world live with a mental disorder. That is nearly 1 billion people. Depression is the leading cause of disability worldwide.
In 2023, the World Health Organization took an unusual step. It launched a new Commission on Social Connection to fight loneliness as a global health threat. The WHO said loneliness is no longer just a personal feeling — it is a public health problem that affects whole countries.
What this means: Mental illness and loneliness are not just personal problems. They are global health issues that need global answers — and local action.
The United States
In 2023, the U.S. Surgeon General, Dr. Vivek Murthy, released a public health advisory. He called loneliness an epidemic. He said the health impact of loneliness is similar to smoking 15 cigarettes a day.
About 1 in 2 U.S. adults report feeling lonely. About 1 in 5 U.S. adults live with a mental illness each year. Suicide rates have risen over the past two decades, and depression among young people has climbed sharply.
Young Adults (18–25)
Are among the loneliest groups — even though they are the most connected online.
Older Adults (65+)
About 1 in 3 older adults feel lonely often, which raises their risk of illness and early death.
What this means: Loneliness is not a sign of weakness. It is a health risk — as serious as smoking or not exercising.
What the Research Shows About Health
Loneliness and weak social connection are linked to serious health problems. A major review of 90 studies found that loneliness is tied to a 26% higher risk of dying early.

Early Death
26% higher risk
The Surgeon General said the health impact of loneliness is comparable to smoking up to 15 cigarettes a day, and is even greater than the risk from obesity or not exercising.
What this means: Connection is not a luxury. It is medicine. Strong relationships protect your body and your mind.
What Helps
The research is clear: social connection, a clear sense of purpose, and regular meaningful conversations protect mental and physical health. People who feel connected have lower rates of depression and anxiety. They live longer. They recover faster from illness.
Strong Social Connection
People with strong relationships live longer and have better health. Even one close friend can make a big difference.
A Clear Sense of Purpose
Research links purpose to lower depression, stronger hearts, and faster recovery. Purpose gives people a reason to keep going.
Regular Meaningful Conversations
Talking with people who let you be yourself — even once a week — lowers stress and builds belonging.
What this means: Purpose and community are two of the most powerful — and most underused — tools we have to fight this epidemic.
The AI Gap — Why a Screen Is Not Enough
The RAND Corporation published a nationally representative survey in JAMA Pediatrics finding that 19.2% of U.S. adolescents and young adults (ages 12–21) reported using AI chatbots for mental health advice in 2025. Among those users, 42.8% turned to chatbots at least monthly, and 91.7% rated the advice as somewhat or very helpful.
Yet most young people kept it secret: 63.3% did not disclose chatbot use to anyone. Use was more common among females, older youth (18–21), and those who had already spoken with a clinician. RAND underscored the need for parents and clinicians to proactively discuss chatbot use — promoting safety, appropriate expectations, and links to evidence-based care.
What this means: Young people are reaching out for mental health support — but too many are reaching out to a screen instead of a person. AI can share information. It cannot form a real relationship. It cannot look you in the eye, sit with you in silence, or truly care. That gap is dangerous.
The Human Layer Voice Up Adds
Voice Up is committed to adding the human layer to this epidemic. The human layer is what can truly make the difference — a real conversation with a real person, forming a real relationship in a safe community. No chatbot can replace the feeling of being heard, understood, and valued by another human being.
Our programs pair every participant with mentors, peers, and purpose-driven cohorts. We create the safe spaces where real conversations happen — the kind that research shows actually heals. Technology can open a door. A person walks through it with you.
How Voice Up Helps
Voice Up connects people to purpose. We build safe spaces for real conversations. We help people name what matters to them, find their community, and take action.
Our five principles — Collaboration, Humility, Precision, Patience, and Empathy — are the habits that keep connection strong. Every program we offer is built to fight this epidemic.
The Purpose Fellowship
Where purpose becomes action — in community.
Health Benefits of Purpose
The evidence that purpose protects health.
Be Stress Free Zone
Evidence-based tools to manage stress.
The Power of Quiet Conversations
The public report on loneliness and purpose.
What You Can Do Today
You do not have to fix everything. You just have to start. Here are three simple steps backed by research:
Reach out to one person today. A text, a call, or a walk together.
Join a community — a group, a class, a fellowship, or a team.
Find your purpose. Ask yourself: what matters to me, and who do I want to help?
The evidence is clear: small acts of connection add up. Be the blessing.
