We all know that exercise is beneficial for both our physical and mental well-being. However, recent research suggests that even the way we sit could have significant implications for our cognitive health. A study led by researchers at The University of Queensland has found that “active sitting”—engaging in activities such as reading, playing cards, or doing crossword puzzles—is linked to better brain function.
The study, which examined over one million middle-aged and older adults from 30 countries, highlights the potential cognitive benefits of mentally engaging sedentary activities. According to Associate Professor Paul Gardiner from the university’s School of Public Health, these findings could inform new public health guidelines aimed at enhancing cognitive health among aging populations.
Redefining Sedentary Behavior
Traditionally, health advice has focused on reducing overall sitting time. However, Dr. Gardiner suggests a more nuanced approach: “Health advice could shift from simply saying ‘sit less’ to encouraging more mentally engaging activities while sitting.” This shift could help individuals make simple yet effective changes that support long-term brain health and potentially reduce the risk of dementia.
The research underscores the importance of distinguishing between different types of sedentary activities. “Total sitting time has been shown to be related to brain health,” Dr. Gardiner explained. “However, sitting is often treated as a single entity, without considering the specific type of activity.”
Active Sitting and Cognitive Benefits
Mentally active sedentary activities, such as reading, playing card games, and solving puzzles, were found to be associated with positive cognitive outcomes, particularly in preserving executive function, memory, and cognitive flexibility. “These findings show that small everyday choices—like reading instead of watching television—may help keep your brain healthier as you age,” Dr. Gardiner noted.
“Most people spend many hours sitting each day, so the type of sitting really matters.” — Dr. Paul Gardiner
Global Implications for an Aging Population
Cynthia Chen, the lead researcher, emphasized that the study does not advocate for increased sitting time but rather encourages mindful engagement during sedentary periods. “We know that staying physically active is still essential for overall health,” Ms. Chen stated. “But when we do spend time sitting, choosing activities that stimulate the mind may offer extra protection for our brain.”
The findings are particularly relevant as the global population ages. “Cognitive abilities often decline with aging, and sedentary time is highly prevalent among older adults,” Ms. Chen said. “Dementia is the seventh leading cause of death globally and one of the leading causes of disability and dependency among older people worldwide.”
“Activities requiring active thinking, problem-solving, and continuous learning could mitigate cognitive decline.” — Cynthia Chen
Future Directions and Public Health Policy
The research, conducted in collaboration with Western University in Canada, Lung Foundation Australia, and Griffith University, has been published in the Journal of Alzheimer’s Disease. It suggests that public health policies could be refined to promote mentally engaging activities during sitting as a strategy to improve cognitive health.
As the world grapples with the challenges of an aging population, these insights could play a crucial role in shaping interventions aimed at preserving cognitive function and reducing the burden of dementia. The study’s findings offer a promising avenue for individuals looking to make impactful lifestyle changes that support brain health.
Moving forward, researchers and policymakers alike will need to consider how these insights can be integrated into broader health strategies. Encouraging active sitting could become a key component of public health initiatives aimed at enhancing the quality of life for older adults worldwide.
