British scientists: Gardening improves mental function in old age

Gardening has a positive effect on cognitive functions in old age, according to a recent study by scientists from the University of Edinburgh, reports Kazinform.

The study, which involved hundreds of elderly participants, found that those who gardened had better cognitive abilities compared to those who did not. This correlation held true even after considering socio-economic status, education, childhood cognitive abilities, health, and overall physical activity.

Researchers conducted the study as part of a long-term project tracking participants throughout their lives. The participants took an intelligence test at age 11 and repeated it at age 79. They also provided lifestyle data and underwent frequent cognitive assessments up to age 90.

Out of 467 participants, about 31% never gardened, while 43% gardened regularly. Those who gardened showed more significant cognitive improvement over their lifetimes. Between the ages of 79 and 90, cognitive abilities generally declined, but gardeners maintained an advantage in memory, problem-solving, and verbal fluency.
