Why People Who Do This Daily Activity Have Lower Dementia Risk

Engaging in daily physical activity, even for just a few minutes, can significantly lower the risk of developing dementia. Recent studies have shown that older adults who incorporate moderate to vigorous exercise into their daily routine experience a substantial reduction in dementia risk. This is particularly encouraging for those who may feel they cannot engage in extensive exercise due to frailty or health issues.

### The Power of Short Exercise Sessions

Research conducted by the Johns Hopkins Bloomberg School of Public Health found that as little as five minutes of light exercise per day can make a difference. The study analyzed data from nearly 90,000 adults in the UK who wore activity trackers, revealing that those who engaged in at least 35 minutes of moderate to vigorous physical activity per week had a 41% lower risk of developing dementia compared to those who were sedentary[1][3].

Moreover, the benefits increase with more exercise. Participants who exercised between 35 to 70 minutes per week saw a 60% reduction in dementia risk, while those who exercised for 70 to 140 minutes per week had a 63% lower risk, and those exercising over 140 minutes per week had a 69% lower risk[1][3].

### How Exercise Helps

Exercise is believed to help reduce dementia risk by improving blood flow to the brain, enhancing the disposal of metabolic waste, and decreasing inflammation[1]. These mechanisms contribute to healthier brain function and may also be linked to other lifestyle choices that support cognitive health, such as better sleep, diet, and social engagement[1].

### Other Daily Habits That Support Brain Health

In addition to exercise, other daily habits can contribute to lowering dementia risk. Staying hydrated by drinking plenty of water is essential for maintaining overall health, including brain function[2]. Eating a balanced diet, particularly one that is protein-dense, can help support cognitive health and prevent age-related muscle loss[2]. Engaging in mentally stimulating activities, such as reading, and maintaining social connections are also important for cognitive well-being[2].

### Conclusion

While no single activity guarantees complete prevention of dementia, incorporating physical exercise and other healthy habits into daily life can significantly reduce the risk. Even small amounts of exercise, combined with a balanced lifestyle, can make a substantial difference in maintaining brain health as we age.
