Healthy Habits to Lower Dementia Risk
As Singapore’s population ages rapidly, looking after mental health and maintaining cognitive function has never been more important. According to the Ministry of health, by 2030, the number of people living with dementia in Singapore could rise to around 152,000 as the population becomes super-aged.
But there is encouraging news, research shows that lifestyle habits and community support can make a real difference in maintaining mental wellbeing and lowering dementia risk.
Stay Physically Active Every Week
Regular physical activity does not just keep the body healthy, it is one of the most powerful ways to support brain health too.
Aim for at least 150 minutes of moderate exercise weekly, such as brisk walking, tai chi, or swimming.
Group activities like dance classes or Active Ageing Centre sessions can boost mood and social engagement, which are linked to better cognitive outcomes.
Even housework and daily chores have been shown to benefit memory and attention in seniors.
Exercise increases blood flow to the brain, lowers inflammation, and supports new neural connections, all of which are important for both mental health and cognitive resilience.
Keep Your Brain Engaged
Use it or lose it certainly applies to the brain. Active engagement helps maintain neural connections and builds what researchers call a cognitive reserve.
Seniors can try activities such as:
- Puzzles and memory games
- Reading, writing, or learning new skills
- Digital classes and simple mobile games
- Language learning and music classes
Community programmes across Singapore often include these activities at Active Ageing Centres, with cognitive games specially designed to improve memory and thinking skills.
Eat a Brain Healthy Diet
Nutrition plays a big role in mood regulation and long term brain health. Key tips include:
Choose more vegetables, fruits, whole grains, and fish.
Include leafy greens and antioxidant rich foods that support cognition.
Stay well hydrated throughout the day.
One eating pattern often recommended for brain health is the MIND diet. The MIND diet stands for Mediterranean DASH Intervention for Neurodegenerative Delay. It combines elements of the Mediterranean diet and the DASH diet, both of which are linked to better heart and brain health.
The MIND diet encourages eating more leafy green vegetables, other vegetables, fruits, whole grains, nuts, beans, and fish. It also recommends limiting foods high in saturated fat, sugar, and salt, such as fried foods and processed snacks.
Protect Heart Health to Protect the Brain
The brain relies on healthy blood vessels. Conditions such as high blood pressure, high cholesterol, diabetes, and obesity are linked to a higher risk of dementia if left unmanaged.
Support both heart and brain by:
- Attending regular health screenings
- Following medical advice for chronic conditions
- Maintaining a healthy weight
- Staying physically active and eating well
Many dementia prevention strategies overlap with cardiovascular care
Stay Socially Connected
Loneliness and social isolation are major risk factors for depression and cognitive decline among older adults.
Participating in social activities or simply talking regularly with friends and family stimulates the brain and supports emotional wellbeing.
Group activities at community centres, interest groups, and family gatherings all help reduce feelings of isolation.
Regular social interaction has been linked to better memory and mental resilience.
Strong social connections also make daily life more meaningful, which contributes positively to mental health.
Prioritise Quality Sleep
Sleep is essential for brain health. It is when the brain clears waste, consolidates memories, and repairs itself.
Seniors should aim for seven to nine hours of sleep each night.
Maintaining a regular sleep schedule and limiting caffeine intake in the evening can help.
Simple bedtime routines such as light stretching, reading, or calming music may improve sleep quality.
Good sleep supports mood, memory, and overall cognitive function.
Manage Chronic Health Conditions
Healthy habits that support heart health also protect brain health.
Managing blood pressure, cholesterol, and diabetes can lower the risk of cognitive decline.
Avoiding smoking and limiting alcohol intake further supports long term brain health.
Good physical health improves blood flow to the brain and reduces inflammation, both of which are important for maintaining cognitive function in later years.
