Gardening may help prevent dementia, according to recent research. A 2025 study found that people who were more physically active, including through activities like gardening, had lower levels of proteins in their blood linked to Alzheimer’s disease[9]. They also performed better on memory and thinking tests.
Gardening offers many benefits that could help keep the brain healthy as we age. It provides light exercise, which is good for overall health[3]. Tasks like digging, watering, and weeding can improve strength, coordination, and endurance. This physical activity may help lower the risk of conditions like heart disease and diabetes that are associated with higher dementia risk.
Being outside in nature while gardening can reduce stress and anxiety[7]. The peaceful environment promotes relaxation. Gardening engages multiple senses and can be very calming. It may help decrease feelings of loneliness and isolation, especially for older adults.
Gardening also provides mental stimulation. Planning a garden, learning about different plants, and problem-solving garden issues all exercise the brain[1]. This cognitive engagement could help maintain thinking skills. Some research suggests horticultural therapy may even improve cognitive function in people with dementia after just a few months.
For seniors, gardening can provide a sense of purpose and accomplishment[3]. Nurturing plants and watching them grow can be very rewarding. Gardening allows older adults to stay productive and feel they are contributing. This may boost mood and self-esteem.
While more research is still needed, incorporating gardening into your routine appears to be a fun, low-cost way to potentially reduce dementia risk. Even small gardening projects like growing herbs in pots can provide benefits. As with any new physical activity, it’s wise to check with your doctor first, especially if you have any health conditions. But for many people, gardening could be an enjoyable hobby that’s good for both body and mind.
