The Surgeon General has declared loneliness a public health epidemic. For veterans, it isn’t new — it’s been the quiet crisis hiding behind every other one.
There’s a specific kind of alone that veterans know. Not just being by yourself in a room — but feeling like no one around you would understand what you’ve been through, what you’ve seen, or who you were before the uniform came off. That loneliness can exist in a crowded room. It can exist in a marriage. It can exist at a family dinner on Thanksgiving, surrounded by people who love you.
It is one of the most common experiences among post-9/11 veterans. And it is one of the most dangerous.
In 2023, U.S. Surgeon General Dr. Vivek Murthy declared loneliness a national public health epidemic — comparing its health effects to smoking 15 cigarettes a day. Veterans were already living inside that statistic. Research consistently shows that veterans experience loneliness and social isolation at rates significantly higher than the general population, and that isolation is one of the strongest predictors of veteran suicide risk.
We don’t talk about it enough. So let’s talk about it.
Why Veterans Are So Vulnerable to Isolation
Military life is, in many ways, the opposite of loneliness. You are never truly alone. You sleep in the same barracks, run the same miles, eat in the same chow hall. Your unit is your family — bound not by blood but by shared hardship, shared purpose, and shared identity. The military doesn’t just give you a job. It gives you a tribe.
When that ends, the loss is total. One day you have a hundred brothers and sisters. The next day, you have a DD-214 and a civilian wardrobe.
Civilian friendships don’t form the same way. They don’t carry the same depth or the same speed. In the military, you build bonds under pressure — shared danger, shared sacrifice, shared exhaustion. In civilian life, you build them over coffee and small talk, slowly, across months and years. For veterans already carrying invisible wounds, that pace can feel impossibly slow. And so many stop trying.
There’s also the gap of shared experience. Most civilians haven’t deployed. Most haven’t lost a teammate. Most don’t understand what it means to spend years in a place where every decision could get someone killed — or what it feels like to come home and not know what to do with that weight. Veterans often describe feeling like they’re speaking a language no one else understands. Over time, many simply go quiet.
What Isolation Does to the Body and Mind
Loneliness is not just an emotional experience. It is a biological one. Research has shown that chronic social isolation increases inflammation, disrupts sleep, weakens immune function, and raises the risk of heart disease, depression, and dementia. For veterans already managing PTSD, TBI, or chronic pain, isolation compounds every one of those conditions.
The connection to mental health is especially stark. Isolation removes the natural checks that social connection provides — the friend who notices something is off, the community that gives you a reason to show up tomorrow, the people who witness your life. Without that, dark thoughts have nowhere to go but inward.
This is not a weakness. It is a predictable outcome of a system that trains people for total belonging and then releases them into a world that wasn’t built to receive them.
The Signs to Watch For
Veteran isolation often doesn’t look like what people expect. It isn’t always the veteran who never leaves the house. Sometimes it’s the one who is constantly busy — filling every hour with work or training or projects — because stillness feels unbearable without connection to fill it. Watch for veterans who:
- Have pulled away from people they used to be close to
- Describe feeling like no one really knows them
- Have lost interest in activities or communities they used to enjoy
- Say things like “nobody would understand” or “I don’t want to be a burden”
- Have no one they feel comfortable calling in a crisis
If you recognize yourself in that list, you are not broken. You are describing something that millions of veterans feel, and that is both real and fixable.
Connection Is Not a Luxury — It’s Medicine
The research on what actually helps is clear: connection. Not therapy (though therapy helps). Not medication (though medication helps). The thing that most consistently protects against isolation’s worst effects is the presence of other people who know you, show up for you, and share something real with you.
For veterans, that often means other veterans. There is something irreplaceable about being in a room with people who don’t need everything explained. Who understand the dark humor. Who get it when you go quiet. Peer connection — veteran to veteran — is one of the most powerful protective factors we know of.
That’s why programs built around shared activity matter so much. A training program, a hiking group, a fitness community — they’re not just good for the body. They rebuild what separation from service destroyed: a reason to show up, people who notice when you don’t, and the quiet, steady experience of belonging to something again.
What You Can Do — Today
If you’re a veteran feeling isolated: Reach out to one person this week. Not to explain everything — just to make contact. A text. A call. Showing up somewhere you’ve been avoiding. The hardest part is always the first step, and it almost always feels better than you expect it to.
If you know a veteran who has gone quiet: Reach out. Not with resources or advice — just with presence. “I’ve been thinking about you. How are you really doing?” That question, asked sincerely, opens more doors than almost anything else.
If you’re a community member, employer, or neighbor: Know that the veteran near you may be struggling with something they haven’t told anyone. Creating a genuinely welcoming environment — one where they feel seen and valued outside of their military identity — matters more than you know.
At Boots to Health Foundation, we build community on purpose. Every program we run, every veteran we serve, is part of our answer to isolation — a community that shows up, that shares the work, and that reminds every veteran who walks through our door that they don’t have to figure this out alone.
If you or a veteran you know is struggling with isolation, reach out to us. We are here — and we will show up.
