How Volunteering Helps With Depression and Anxiety: What the Research Shows

The mental health benefits of volunteering are well-documented — but they don't apply equally to all types of helping or all types of people. Here is what actually works, for whom, and why.

I spent about four months in a period of fairly serious depression some years back. I won't go into the details because they're mine, but I will say this: the thing that shifted it, more than anything I tried, was an accidental volunteering commitment I had made two months before it hit and felt too guilty to cancel. Two hours a week at a community garden, mostly weeding and occasionally helping an elderly man named Einar with his tomato plants.

I'm not saying volunteering cured my depression. I'm saying it gave me somewhere to put my body and a reason to leave the house when nothing else was doing that. And there is research behind why that mattered.

What the Studies Actually Show

A 2020 systematic review published in BMC Public Health analyzed 56 studies on volunteering and mental health outcomes. The headline finding: regular volunteering was associated with significantly lower rates of depression, higher self-reported wellbeing, and reduced social anxiety — particularly for people over 65, but with meaningful effects across age groups.

The mechanisms proposed: structured activity (giving shape to otherwise formless time), social contact (reducing isolation), a sense of purpose (something the self-focused mental state of depression explicitly disrupts), and what researchers call "self-transcendence" — the temporary relief of focusing on something outside your own problems.

Not All Volunteering Is Equal

Here's where it gets specific. The mental health benefit of volunteering appears to be significantly mediated by two factors: whether the helping feels freely chosen (obligatory helping produces no benefit and sometimes worsens outcomes) and whether there's genuine human contact involved.

Remote, task-based volunteering — data entry, spreadsheet work — shows much smaller mental health effects than roles involving direct contact with people or animals. This isn't surprising from a neurological standpoint: in-person social interaction activates complex reward and bonding circuitry in ways that screen-based tasks don't. For mental health specifically, getting yourself into a room with other people — even if the conversation is mostly about tomatoes — appears to be a significant part of the mechanism.

Volunteering as Complement, Not Replacement

This needs to be said clearly: volunteering is not treatment for clinical depression or anxiety disorder. The research on it positions it as a complement to treatment — something that can meaningfully improve outcomes when combined with professional care, not something that replaces it.

That said, for mild to moderate depression and social anxiety, the evidence is strong enough that several UK health systems have begun formally incorporating "social prescribing" — including volunteering — as part of mental health care pathways. The NHS's social prescribing program has referred over 900,000 people to community activities since 2019.

How to Start When You Don't Feel Like It

The hardest part is that depression specifically impairs the motivation to do the things that would help. This is the cruel circularity of it. A few things that help: choosing a commitment made to a specific person (harder to cancel than to an organization), keeping the time commitment genuinely small (two hours, not a day), and choosing something with a reliable sensory component — being outdoors, working with your hands, being around animals — which tends to interrupt rumination more effectively than abstract tasks.

FAQ

Is there evidence that volunteering specifically helps with anxiety? Less robust than for depression, but yes — a 2019 study in Anxiety, Stress and Coping found that regular volunteering was associated with significantly lower social anxiety scores, primarily through the mechanism of structured, low-stakes social exposure.

What if I'm too unwell to volunteer? Then don't. Forcing yourself into high-demand situations when you're at your worst can backfire. The research applies to mild to moderate difficulties, not acute mental health crises. Start with very low-commitment options when you're stable enough, not when you're at the bottom.
