Swimming : How to avoid the dementia ?

 

It is strange that Australians do not know swimming can reduce the dementia problem. 

Here is the info from You Tube.

AI said it this way:

While swimming cannot completely "prevent" dementia, it is one of the most effective physical activities for reducing your risk of cognitive decline and delaying the onset of symptoms. [1, 2, 3]

Research indicates that swimming can lower dementia risk by up to 28% . The combination of cardiovascular conditioning and unique aquatic benefits provides a substantial boost to brain health: [1, 2]

• Improved Blood Flow: Vigorous swimming, such as swimming laps for 20 minutes multiple times a week, increases blood flow to the brain, which enhances short-term memory and reduces oxidative damage. [1, 2]
• Brain Volume Protection: According to research from the American Academy of Neurology, regular activities like swimming can actually prevent age-related brain shrinkage, preserving overall cognitive function . [1]
• Reduced Biomarkers: Studies have shown that consistent vigorous exercise helps reduce blood-based proteins strongly associated with the onset of dementia . [1]
• Cold Water Benefits: Early research from the University of Cambridge suggests that cold water swimming may stimulate "cold-shock" proteins (like RBM3) that have been shown to protect the brain from neurodegenerative diseases. [1, 2]
• Mental Well-being: Swimming is a low-impact, resistance-friendly exercise that supports joint mobility and provides a calming sensory experience. It helps lower stress, soothe anxiety, and promote better sleep—all of which are critical for preserving cognitive health. [1, 2, 3]

For more evidence on how physical activity supports brain health, check out the Alzheimer's Society or the comprehensive studies detailed by PubMed Central. [1]

Dementia is now Australia's biggest killer. Insight examines how patients, carers and the government's support systems are equipping themselves to manage this public health crisis. This Insight episode is Dealing With Dementia.
