Interesting, the more you exercise (Even up to 7 days a week), the more it counts for the brain. 2-3 times a week vs daily. (of coz for those after timing, gotta be mindful of recovery / 1 rest day esp for older folks and not mindful about various recovery factors etc).
Needs to be aerobic....probably something to do with the mitochondria (zone 0 slower walks dont count, for eg, pls raise the pace up to Z1 or Z2).
edit - but of coz this is just one facuet to better brain health..... got others also la.
Video Summary: The Exercise Neuroscientist: NEW RESEARCH – The Shocking Link Between Exercise And Dementia!
Neuroscientist Dr. Wendy Suzuki (NYU) shares powerful, research-backed insights into how exercise, diet, social connection, and self-care can dramatically improve brain health—protecting memory, mood, and reducing dementia risk.

Key Points (Bulleted)
Exercise transforms the brain
Aerobic activity boosts neuroplasticity, increases growth factors like BDNF, and builds new neurons in critical regions (hippocampus and prefrontal cortex) .
Dementia risk slashed
Regular physical activity can reduce dementia risk by ~50% and delay its onset by over a year for middle-aged adults .
Hippocampus & Prefrontal Cortex – the key duo
Hippocampus: essential for forming and retaining long-term memories.
Prefrontal cortex: responsible for attention, focus, decision-making, and personality.
Both regions thrive with exercise and meditation .
**Brain = “big, fat, fluffy”**
Using Dr. Suzuki’s metaphor: a well-maintained brain is larger, healthier, and richer in connections—paralleling enhanced life satisfaction.
Lifestyle toolkit for brain health
1. Exercise (focus on aerobic workouts—30–45 min, 2–3× weekly minimum).
2. Meditation (boosts prefrontal cortex).
3. Mediterranean-style diet (high in unprocessed, colorful foods).
4. Social connection (buffers against brain shrinkage and dementia risk) .
Self-care rituals matter
Dr. Suzuki’s morning routine: silent “tea meditation,” exercise, hot–cold contrast showers, promoting mood, focus, and alertness .
Antagonists to brain health
Sleep deprivation, sedentary lifestyles, processed food, alcohol, smoking, excessive screen time, and chronic stress all degrade brain function—and increase dementia risk .
Emotions, love, and memory
Experiences charged with emotion, novelty, or love activate reward circuits in the brain, strengthening memory encoding and social bonds. Isolation, conversely, shrinks those neural pathways .
Anxiety on the rise
Everyday anxiety (driven by global issues and social media) impairs cognition. Exercise, deep breathing, and meditation help reset the stress response .

Supporting Highlights (via Glasp)
From Glasp’s summary:
"Regular exercise, particularly aerobic activities, promotes brain plasticity and the growth of new brain cells."
"The Mediterranean diet ... is beneficial for brain health."
"Maintaining strong social connections can help protect against brain deterioration."
"Everyday anxiety ... can have negative effects on brain function."

Practical Takeaways
1. Commit to regular aerobic exercise – even 10 minutes helps; aim for 30–45 minutes, 3–5× per week.
2. Adopt a Mediterranean-style diet – include fruits, vegetables, healthy fats, and unprocessed whole foods.
3. Cultivate social interactions – prioritize in-person connection to support mental and neurocognitive health.
4. Start a mindfulness practice – 10 minutes of meditation or deep breathing can significantly improve focus and stress resilience.
5. Protect sleep and reduce screen time – both are essential for waste clearance and memory consolidation.

Conclusion
Dr. Wendy Suzuki’s research offers one of the most compelling neuroscience frameworks: sustained aerobic exercise, healthy eating, social bonds, mindfulness, sleep, and limiting toxins each contribute to a "big, fat, fluffy" brain—more resilient, joyful, and resistant to aging and dementia.
