How many studies support Volunteering?
Formal volunteering has a substantial observational literature linking it to lower mortality, though the size of the effect shrinks sharply once confounders are addressed. That's backed by 6 published studies in Vitaebase's database, including 2 meta-analyses, the most recent from 2025 -- a modest but real research base.
