Just 5 Minutes Of This Activity Can Reduce Dementia Risk by 41 Percent, Reveals Study

Dementia is a growing public health concern, especially since there is no known cure. Scientists are constantly researching lifestyle and dietary habits that can help reduce the risk of developing this brain disorder. A new study published in the Journal of Post-Acute and Long-Term Care Medicine has revealed a surprising finding—just five minutes of daily exercise can lower dementia risk by 41 per cent.

Researchers studied 90,000 adults, tracking their physical activity using wrist accelerometers. The study found that even a small amount of exercise could make a huge difference. Participants who engaged in just 35 minutes of moderate exercise per week—which equals about 5 minutes per day—experienced a significant reduction in dementia risk.

This finding challenges the long-standing belief that at least 150 minutes of exercise per week is needed for brain health. Lead author Amal Wanigatunga emphasized the importance of even small amounts of movement, stating, "Our findings suggest that increasing physical activity, even as little as five minutes per day, can reduce dementia risk in older adults. Some exercise is always better than none."

How Much Exercise Lowers Dementia Risk?

The study followed participants over several years and found a strong link between exercise duration and dementia prevention:

- 5 minutes daily (35 min/week) - 41 per cent lower dementia risk

- 36–70 minutes per week - 60 per cent lower risk

- 71–140 minutes per week - 63 per cent lower risk

- More than 140 minutes per week - 69 per cent lower risk

The research shows that even a small commitment to physical activity can have life-changing benefits, particularly for ageing adults.

What Is Dementia?

Dementia is a progressive brain disorder that causes memory loss, confusion, and difficulty with daily activities. It results from damage to brain cells and is often associated with harmful protein buildup in the brain. The most common type is Alzheimer’s disease, but other forms exist.

Since dementia worsens over time and has no cure, scientists focus on ways to slow its progression and improve brain health. Exercise has emerged as a powerful preventive tool.

Tips to Keep Your Brain Sharp

While exercise is an effective way to reduce dementia risk, adopting a healthy lifestyle can further improve brain health. Here are some expert-recommended tips:

1. Stay Active – Engage in walking, yoga, or light strength training for at least a few minutes daily.

2. Eat Brain-Boosting Foods – Include berries, nuts, leafy greens, and fish rich in Omega-3s.

3. Keep Your Mind Engaged – Read, solve puzzles, or learn a new skill.

4. Get Enough Sleep – Aim for 7-9 hours of quality sleep per night.

5. Manage Stress – Practice meditation, deep breathing, or relaxation techniques to reduce mental strain.

6. Stay Socially Connected – Engage in conversations and spend time with loved ones to stimulate brain function.

This study shows that small lifestyle changes can have a big impact. While dementia remains a major health challenge, a few minutes of daily exercise could help protect the brain and improve overall well-being. Scientists hope that further research will confirm these findings and encourage more people to prioritize their brain health.
