When it comes to keeping your brain healthy as you age, you probably think about exercising regularly, eating nutritious foods, getting enough sleep and keeping your mind active. But what if one of the best things you could do for your brain had nothing to do with your own health routine?
New research suggests that helping other people may be another way to maintain cognitive health as you get older. Whether you're volunteering in your community, lending a hand to a neighbor or helping a friend through a difficult time, those acts of kindness could benefit your brain, too.
What Science Says About Helping Others and Brain Health
A 2025 study published in Social Science & Medicine examined the relationship between helping others and cognitive function using data from more than 31,000 American adults collected over two decades.
Researchers found that people who volunteered or provided informal assistance to friends, family and neighbors outside their households experienced slower age-related cognitive decline than those who didn't engage in these activities. Both forms of helping were associated with higher cognitive function and slower decline, while continued participation was linked to benefits that accumulated over time.
One particularly interesting finding? You don't have to dedicate countless hours to volunteering to potentially benefit. Researchers identified approximately two to four hours per week as a level of participation consistently associated with the most favorable cognitive outcomes.
And this isn't the only research pointing in that direction. A 2024 systematic review published in Geriatric Nursing examined 17 studies on volunteering and cognitive performance in older adults. Sixteen of those studies found a positive association between volunteering and aspects of cognitive health, including memory and verbal fluency.
Although these findings are encouraging, researchers caution that more studies are needed to determine whether helping others directly slows cognitive decline.
How Might Helping Others Support Brain Health?
Helping someone else might seem like a simple act of kindness, but it often involves several activities associated with maintaining cognitive function.
- Social Connection: Meaningful interactions with other people help keep your brain engaged. Conversations, shared experiences and relationships encourage communication, memory and emotional awareness. Regular social interaction is also associated with better cognitive health as we age.
- Mental Stimulation: Helping others frequently involves problem-solving, planning and learning. Whether you're organizing a community event, mentoring someone or figuring out how to assist a neighbor, you're giving your brain opportunities to stay mentally active.
- A Sense of Purpose: Having meaningful responsibilities and feeling that your contributions matter can promote emotional well-being. Volunteering often provides structure, personal satisfaction and a reason to stay engaged with the world around you.
- Physical Activity: Some forms of helping naturally get you moving. Participating in a community cleanup, delivering meals or assisting with outdoor projects can add movement to your day. Regular physical activity is another important part of maintaining brain health.
Researchers believe these experiences may help explain the connection between helping others and cognitive health, although the specific mechanisms are still being studied.
Small Acts of Kindness Can Make a Difference
The good news? You don't need to join a nonprofit organization or rearrange your schedule to make helping others part of your routine. Even small, thoughtful gestures can provide opportunities for meaningful connection and mental engagement.
Here are a few ways to get started:
- Find ways to give back through fitness. Participate in a charity walk, help organize a community wellness event or invite a friend who needs encouragement to exercise with you.
- Share your skills. Mentor a young person, teach someone a new activity or help a friend develop healthier habits through meal preparation or fitness.
- Look for everyday opportunities. Check in on an older neighbor, help someone with errands, volunteer at a local food pantry or offer assistance to someone recovering from an illness.
The key is finding activities you genuinely enjoy and can maintain consistently. While two to four hours a week was associated with favorable outcomes in the 2025 study, there's no need to treat volunteering like another item on your fitness tracker. Start with what fits your schedule and build from there.
Healthy Aging Is About More Than Physical Fitness
Taking care of your body and boosting your brain power aren't separate goals. A balanced approach to healthy aging includes regular exercise, nutritious eating, quality sleep, mental stimulation and meaningful relationships.
Research increasingly suggests that staying socially engaged and contributing to the lives of others may be another valuable piece of that picture.
At Nutrishop, we believe wellness goes beyond what happens in the gym or what you put on your plate. Building healthy habits also means making time for activities that enrich your life and strengthen your connections with others.
So, the next time you have an opportunity to lend someone a hand, consider saying yes. You might be doing something good for your own health in the process.
