The unexpected benefits of volunteering: Happiness, health, and connection

We often think of volunteering as an act of service, something we do to help others, improve communities, or support a cause we care about. And it is all of those things. But what’s often overlooked is how much volunteering gives back to the volunteer. Beyond the warm feeling of doing something good, research and real-life stories increasingly show that volunteering offers a range of unexpected personal benefits—boosting happiness, improving health, and strengthening social bonds. In short, giving your time may be one of the best things you can do for yourself. 

It might sound like a cliché, but the phrase “helper’s high” is rooted in real science. Studies show that acts of kindness and service activate the brain’s reward system, releasing feel-good chemicals like dopamine and oxytocin.

A study published in Social Science and Medicine found that people who volunteer regularly report higher life satisfaction and greater happiness than those who don’t. In fact, some researchers say the mental health benefits of volunteering are comparable to those of regular exercise. Why? Because volunteering gives us a sense of purpose. When we help someone else—whether it’s cooking a meal for a shelter, mentoring a student, or walking a dog at a rescue centre—we’re reminded that our actions matter. That we matter.

For many, especially during tough times, volunteering becomes a way to reclaim optimism and focus on what’s good in the world. 
“After losing my job, I started volunteering with kids on weekends. I thought I was just filling time,” says Karabo, a 32-year-old graphic designer in Johannesburg. “But it actually lifted me out of a dark place. I felt useful again.” 

In an age where stress, anxiety, and isolation are on the rise, volunteering offers an antidote. It gets us out of our heads—and out of the house. It shifts our attention from personal worries to collective action. And it offers something that’s increasingly rare in modern life, human connection with no agenda.

People who volunteer regularly often report lower levels of depression and anxiety. Volunteering also builds resilience, helping people process grief, trauma, and major life changes. Importantly, it allows for emotional expression in a safe, meaningful context. Whether it’s comforting someone in crisis or helping an animal in need, volunteering taps into our empathy—and in turn, strengthens it. 

Believe it or not, volunteering may even add years to your life. Research from Harvard University and the University of Exeter found that people who volunteer have lower blood pressure, reduced risk of chronic illness, and better mobility in older age. Seniors who volunteer are less likely to experience cognitive decline or develop dementia.

It’s not just the physical activity involved—although that helps too—it’s also the social interaction and emotional benefits that promote overall well-being. Even for younger people, volunteering can lead to better sleep, lower stress, and healthier lifestyle habits. Why? Because it encourages routine, structure, and a sense of accountability—without the pressure of a job or deadline.

One of the most beautiful benefits of volunteering is the opportunity to connect—with people, animals, and causes. In a world that can feel increasingly disconnected and digital, volunteering offers real, in-person interactions based on shared values.

You meet people you might never otherwise cross paths with: retirees with wisdom to share, teenagers with bold ideas, community members with inspiring stories. These connections often grow into friendships, mentorships, and lasting community bonds.

“I joined a community gardening project just to help out,” says Lerato, a 47-year-old teacher.

“Now we’re like family. We check in on each other, celebrate birthdays, and share produce. It’s more than volunteering—it’s a whole support system.”

This sense of belonging and shared purpose is especially powerful for people who feel socially isolated—like recent graduates, new parents, or those adjusting to retirement. 

Volunteering is also a powerful tool for personal growth. It pushes you outside your comfort zone, introduces you to new skills, and often reignites forgotten passions.

Many people discover talents or interests they didn’t know they had: teaching, crafting, cooking, mentoring, event planning. Some even find new career paths or business ideas through volunteering.

Volunteering also builds confidence. When you successfully organise a donation drive, teach a child to read, or speak up in a group setting—you realise what you’re capable of. For young people, especially, volunteering can shape identity, values, and ambition. It teaches leadership, communication, and problem-solving in real-world settings. And it looks great on a CV—not just for the experience, but for the character it reflects.
