Simple Lifestyle Change Like Walking May Lower Risk of Dementia and Heart Disease

 

Making a few lifestyle changes can serve as simple and effective strategies to reduce the risk of chronic diseases such as dementia and heart disease—especially among older adults. One of the most accessible options is walking, which, according to a report by Times of India, offers significant protection against these conditions as we age.



The Importance of Walking Speed in Reducing Dementia Risk

An evaluation based on the Lifetime Total Physical Activity Questionnaire revealed that both the intensity and duration of walking play a crucial role in cognitive health outcomes. Participants were classified according to their walking pace, intensity (low, moderate, or vigorous), and the age at which they began walking regularly (midlife vs. later life).


According to research from India’s National Library of Medicine (NLM), physical activity is a low-cost and effective preventive measure against dementia. Recent studies indicate that even one form of activity—walking—can have a positive impact on brain health. Walking requires no special training, costs nothing, and can be done nearly anywhere, making it a practical choice for people of all ages.


It’s important to note that a slow walking pace is considered a major risk factor for Alzheimer’s symptoms or their progression. This suggests an inverse relationship between walking and cognitive decline: the more regularly one walks, the lower the risk—and vice versa. Long-term studies support this idea. For example, older women who walked at a brisk pace had a significantly lower chance of cognitive decline over 6–8 years. Similarly, older men who maintained a regular walking routine showed a reduced risk of developing dementia.


Key findings showed that individuals who walked regularly—especially those walking more than 360 minutes per week at moderate to vigorous intensity—had a lower risk of Alzheimer’s-related cognitive decline compared to those who walked less frequently or with lower intensity. The timing of when walking was introduced also mattered: those who started walking during midlife (ages 40–64) experienced stronger cognitive protection than those who began later in life.


How Walking Helps Prevent Heart Disease

Multiple studies have shown that walking regularly, even just 20 to 60 minutes a day several times a week, can significantly reduce the major risk factors associated with heart disease.


A review of 14 walking-based interventional studies—published by the National Library of Medical Sciences between 2009 and 2010—found that participants who followed a walking routine for 12 months showed ongoing improvements in cardiovascular fitness, a key factor in heart disease prevention. Participants reported increased endurance, easier breathing during activity, and better overall exercise performance.


Moderate-intensity walking—the kind that increases your breathing, makes you sweat slightly, or causes a mild flush—was found to be most effective in boosting heart strength and blood flow. In some cases, walking also helped reduce blood pressure, particularly among individuals with mild hypertension or those at higher risk due to aging or other conditions.
