New research indicates that different types of sedentary behavior have varied health impacts. Activities such as watching television were associated with lower memory and cognitive skills, while "active sitting," including playing cards or reading, correlated with improved brain health.
Associate Professor Paul Gardiner from The University of Queensland’s School of Public Health stated that the nature of sitting is significant, given the extensive time people spend sedentary. Gardiner suggested that health advice could evolve from simply reducing sitting to encouraging more mentally engaging activities during sedentary periods. This approach aims to facilitate realistic changes that support long-term brain health and may mitigate dementia risk.
The study analyzed the effects of passive and active sedentary activities on cognitive function in over one million middle-aged and older adults across 30 countries. Findings revealed that mentally active sedentary behaviors, such as reading, engaging in card games and puzzles, using computers, and driving, may contribute to preserving executive function, memory, and cognitive flexibility.
Cynthia Chen, the lead researcher, clarified that the findings do not advocate for increased sitting, regardless of its active or passive nature. Chen emphasized the ongoing importance of physical activity for overall health, adding that choosing mentally stimulating activities during sedentary periods might offer additional protection for brain health.
The research has been published in the Journal of Alzheimer’s Disease. Collaborating institutions included Western University in London, Canada; Lung Foundation Australia; and Griffith University.
