The World Health Organization reports that about one in five older adults experience depression, anxiety, and dementia-related mood changes. While therapy can help, volunteerism can be a surprising antidote to seniors’ mental health concerns.

Volunteering offers a renewed sense of purpose and helps combat social isolation, which can reduce depression and anxiety. According to Voices for National Service, older adults who volunteer have a reduced risk of mortality, greater optimism, and feel less depressed and lonely. People who were once working full time and are now retired may find they have hours to spare. Those hours can be directed toward volunteer efforts, which can boost seniors’ mental health in myriad ways.
 

  • Lowers depression and anxiety: The National Institutes of Health reports that volunteering can help reduce the risk of depressive symptoms and actively combat feelings of hopelessness. 
  • Decreases social isolation: Points of Light says regular time spent with peers and those being helped can mitigate loneliness, make stress more tolerable, and increase feelings of belonging. 
  • Restores a sense of purpose: Many retired seniors lose the structure of their working lives. Volunteering enables them to follow a schedule, achieve goals, and play a valuable role in the community again. 
  • Mental stimulation: Volunteering may lead to new skills and interaction with others, helping keep the mind sharp.  
  • Physical activity: Older adults may lead sedentary lifestyles if they have nothing to keep them busy. Volunteering helps a person engage in physical activity. A 2025 study published in the journal Social Science & Medicine found that volunteering is associated with lower levels of hypertension and chronic inflammation. Staying active can lower blood pressure and the risk of heart disease and eight types of cancer. 

Volunteering is a way older adults can stay healthy both physically and mentally.
