4. Get more exercise
Physical activity has been shown to protect against cognitive decline. In data combined from more than 33,000 people, those who were highly physically active had a 38% lower risk of cognitive decline compared with those who were inactive.
Precisely how much exercise is enough to maintain cognition is still under debate. But a recent review of studies looking at the effects of taking exercise for a minimum of four weeks suggested that sessions should last at least 45 minutes and be of moderate to high intensity. This means huffing and puffing and finding it difficult to maintain a conversation.
Australians generally don’t meet the target of 150 minutes of physical activity per week.
