New research published in the American Journal of Preventive Medicine suggests that the type of sitting may significantly affect dementia risk more than the overall amount of time spent sitting. The study shows that mentally active sedentary activities can lower the risk of dementia.
Unlike passive behaviors like watching television, mentally engaging activities such as reading or office work can keep the brain active while sitting, thus reducing dementia risk. This insight emphasizes that how we engage our brains during sedentary time is crucial for brain health.
A study led by Swedish researchers from Karolinska Institute analyzed data from over 20,000 adults aged 35 to 64, tracked from 1997 to 2016. Participants provided details about their sitting habits and other lifestyle factors, which were analyzed against dementia diagnoses found in Swedish health records.
The researchers found that mentally active sedentary behavior correlated with a notable reduction in dementia risk. According to Dr. Mats Hallgren, the study highlights crucial differences between passive and mentally engaging sedentary habits affecting cognitive function.
“While all sitting involves minimal energy expenditure, it may be differentiated by the level of brain activity,” said Hallgren. “How we use our brains while sitting appears to be a critical determinant of future cognitive functioning.”
While maintaining physical activity remains essential as we age, this study underscores the need to stay mentally active, especially when sitting. According to the research, not all sedentary behaviors are equal in terms of brain health; some lead to increased risk, while others may protect against dementia.
The findings could guide public health recommendations and preventive strategies for reducing dementia risk globally. Additionally, it’s important to note the prediction by the CDC that nearly 14 million American adults may develop Alzheimer’s disease by 2060.
Furthermore, research from the Alzheimer’s Association suggests a connection between biological age and dementia risk, alongside findings linking unprocessed meat consumption with reduced dementia risk in people carrying certain genes.
