For older adults aiming to maintain brain health, how they spend their downtime can make a significant difference, according to a new study by the University of South Australia.
Researchers assessed the activity patterns of nearly 400 individuals over age 60 and uncovered the powerful role of mentally stimulating and social behaviors in promoting cognitive function.
The Role of Activity Context in Brain Health
Not all sedentary behaviors are equal when it comes to supporting memory and thinking skills. While passive activities like watching TV or playing video games may seem relaxing, they don’t offer the same cognitive benefits as engaging in more stimulating pursuits.
“Mentally stimulating behaviors, such as reading, listening to music, praying, crafting, and playing a musical instrument — as well as social behaviors like chatting with others — are beneficial for memory and thinking abilities,” the study revealed.
Dr. Maddison Mellow, a researcher involved in the study, highlighted the importance of activity context. “The context of an activity alters how it relates to cognitive function, with different activities providing varying levels of cognitive stimulation and social engagement,” she explained.
Prioritizing Movement and Mental Engagement
While physical activity remains a proven way to reduce dementia risk, the study suggests that even small changes in sedentary behavior can be impactful. “Even small, 5-minute time swaps can help,” Dr. Mellow noted. Replacing passive activities with stimulating ones can enhance cognitive health without requiring dramatic lifestyle changes.
Globally, dementia affects over 55 million people, with 10 million new cases diagnosed each year, according to the World Health Organization. The findings of this study offer valuable insights into preventing cognitive decline, especially as individuals approach their later years.
Predictors of Cognitive Decline
In a related study by the RAND Corporation, researchers identified several predictors that could lead to dementia by age 80. Among these were “never exercising” and “low engagement in hobbies,” emphasizing the critical role of staying physically active and mentally engaged.
Co-author Peter Hudomiet noted the broader benefits of maintaining an active lifestyle. “Maintaining good physical and mental health is beneficial not just to staying in shape, but also to staying sharp and delaying cognitive decline,” he explained.
Top tips for those looking to protect their brain health:
- Engage in stimulating activities: Reading, crafting, or learning to play an instrument can keep the mind sharp.
- Prioritize social connections: Regular conversations and social interactions offer both cognitive and emotional benefits.
- Incorporate physical movement: Enjoyable activities that raise the heart rate are crucial for overall brain health.
- Swap passive behaviors: Replace TV time with a hobby or a quick conversation to boost cognitive stimulation.
By making intentional choices in daily activities, older adults can reduce their risk of dementia while enjoying a more enriching and connected lifestyle.
