Good for the mind
Commenting on the study, Sir Richard Thompson, MD, past president, Royal College of Physicians, London, who has written about the health benefits of gardening, said this new study provides “more evidence that both gardening and art therapy are good for the mind” with mostly equal benefits for the two interventions.

“A much larger study would be needed to strengthen their case, but it fits in with much of the literature,” said Dr. Thompson.
However, he acknowledged the difficulty of carrying out scientifically robust studies in the field of alternative medicine, which “tends to be frowned upon” by some scientists.
Dr. Thompson identified some drawbacks of the study. In trying to measure so many parameters, the authors “may have had to resort to complex statistical analyses,” which may have led to some outcome changes being statistically positive by chance.
He noted that the study was small and that the gardening arm was “artificial” in that it was carried out in a greenhouse. “Maybe being outside would have been more beneficial; it would be interesting to test that hypothesis.”
As well, he pointed out initial differences between the two groups, including income and initial blood pressure, but he doubts these were significant.
He agreed that changes in cardiovascular parameters wouldn’t be expected in healthy young women, “as there’s little room for improvement.
“I wonder whether more improvement might have been seen in participants who were already suffering from anxiety, depression, etc.”
The study was supported by the Horticulture Research Institute, the Gene and Barbara Batson Endowed Nursery Fund, Florida Nursery Growers and Landscape Association, the Institute of Food and Agricultural Sciences, Wilmot Botanical Gardens, the Center for Arts in Medicine, Health Shands Arts in Medicine, and the department of environmental horticulture at the University of Florida. The authors disclosed no relevant financial relationships.
