How To Protect & Enhance Your Brain Health: The Simple Daily Habits That Can Transform Your Mental Performance with Louisa Nicola #522

Feb 12, 2025 2h 10m 32 insights
Do you think that it’s inevitable that the function of your brain will decline as you get older? Or, do you believe that there are simple things you can do each day to preserve, protect and enhance it?   Today’s guest is neurophysiologist and brain health researcher, Louisa Nicola. Louisa is founder of Neuro Athletics, where she works with high-performing individuals to optimise their cognitive function. Nine years ago, Louisa was training to go to the Olympics to represent Australia in the triathlon when she was hit by a car and suffered seemingly insurmountable injuries.    Desperate to accelerate her recovery, she integrated brain training into her approach to physical health and made a near-miraculous recovery. Since then, she has helped many elite performers perform better, think faster and live longer by leveraging neuroscience, exercise physiology, sleep science and nutrition.   In this conversation, we discuss: How our brain works as an intricate network - with 87 billion neurons making approximately 5000 connections each The latest research about Alzheimer's disease, including why it affects more women than men. Why a combination of regular aerobic exercise, high-intensity training, and resistance sessions can help protect brain function The importance of consistent, quality sleep to support your brain's natural cleaning processes And, how supplements like creatine monohydrate and omega-3 fatty acids can support brain health, alongside the right nutrition.   One of the key themes in this conversation is that our daily habits compound over time to either protect or compromise the health of our brains - and, throughout, Louisa shares a variety of practical strategies we can all adopt  - suitable for every age and fitness level.   Louisa’s message is both urgent and hopeful: while our modern lifestyles may be contributing to rising rates of cognitive decline, we have more control over our brain health than we might think.   Support the podcast and enjoy Ad-Free episodes.

Actionable Insights

1. Cultivate Agency & Take Actions

Choose to be in charge of your health by taking small, five-minute actions daily for your well-being, as your outlook and perspective are crucial for improving brain health outcomes.

2. Address Root Causes, Not Symptoms

Focus on lifestyle changes to address the underlying reasons for brain decline, as current Alzheimer’s drugs primarily treat symptoms and don’t prevent recurrence of issues like amyloid buildup.

3. Start Brain Health Interventions Early

Chronic diseases like Alzheimer’s develop over decades, so proactive lifestyle changes in your 20s, 30s, and 40s are crucial for building resilience and protecting future brain health.

4. Understand Compounding Effect of Habits

Recognize that daily habits, whether positive or negative, have a cumulative, compounding effect over time on your longevity, mindset, and brain health, making consistent effort crucial.

5. Exercise for Brain Health

Prioritize exercise as the most impactful intervention for overall health and longevity, recognizing it as medicine that transforms your muscles into “pharmacies” benefiting your brain, rather than solely for physical appearance.

6. Prioritize Strength Training

Engage in strength training as a fundamental part of exercise to increase muscle mass (which declines after age 40) and release myokines, muscle-based proteins that preserve brain synapses, aid neuron survival, and reduce inflammation.

7. Perform Challenging Compound Strength Training

Aim for 2-3 sessions per week of compound movements like squats, bench presses, and lunges, lifting heavy enough that you struggle or shake by the sixth repetition to maximize muscle gain and myokine release.

8. Engage in Moderate Aerobic Exercise Weekly

Commit to at least 3 hours per week of moderate aerobic exercise, such as brisk walking, jogging, cycling, or swimming, at a conversational pace (65-75% of max heart rate), ideally in 45-minute sessions.

9. Incorporate Weekly High-Intensity Exercise

Dedicate 20 minutes per week to high-intensity training (Zone 4/5), such as sprinting or walking up steep hills, to boost blood flow to the brain, increase natural killer cells, and inhibit 13 types of cancer.

10. Grow Brain Connections with Aerobic Exercise

Regular moderate aerobic activity releases Brain-Derived Neurotrophic Factor (BDNF), a growth factor that increases neural connections and the density of the hippocampus, the brain region vital for memory.

11. Combine Physical & Cognitive Tasks

Enhance brain function by performing physical exercises like bodyweight squats while simultaneously engaging in mental challenges, such as counting backwards by seven from 100, to stimulate neural connections and grow gray matter.

12. Integrate Neurocognitive Training

Improve thinking speed, reaction time, and vision by engaging in activities that combine physical movement with cognitive demands, such as throwing a tennis ball against a wall or playing badminton.

13. Improve Vision with Eye Patch Drills

Strengthen neural pathways and improve vision by using an eye patch to temporarily black out one eye while performing simple drills like throwing a ball against a wall, forcing the brain to work harder.

14. Enhance Language Processing with Drills

Stimulate and improve language production in your dominant brain lobe by practicing saying different words that begin with specific letters (e.g., F, S, A).

15. Prioritize Deep Sleep for Toxin Clearance

Ensure sufficient deep sleep (Stage 3/4) to activate the glymphatic system, which uses cerebrospinal fluid to wash out debris, environmental toxins, and amyloid beta proteins that accumulate in the brain.

16. Aim for 7.5+ Hours of Regular Sleep

Sleep at least 7.5 hours per night, adjusting for demanding days, and prioritize regularity by maintaining consistent bedtimes and wake times 80% of the time to support overall health and gene expression.

17. Avoid Chronic Sleep Deprivation

Prevent negative gene expression changes, such as upregulation of tumor-producing genes and downregulation of immunity genes, by avoiding chronic sleep deprivation (e.g., sleeping only six hours a night).

18. Journal Thoughts & Set Evening Standards

To quiet a racing mind before sleep, write down worries in a journal and establish consistent evening routines, such as going offline and dimming lights by a set time, to help your brain settle.

19. Manage Chronic Stress & Inflammation

Actively manage chronic stress to prevent inflammation, a root cause of neural network damage and synapse death; ensure adequate recovery from daily stressors to prevent amyloid buildup.

20. Monitor Inflammation with hs-CRP Test

Get your inflammation levels tested using a high-sensitive C-reactive protein (hs-CRP) blood test, aiming for a result below zero to monitor and manage chronic inflammation.

21. Take 5-12g Creatine Monohydrate Daily

Supplement with 5-12 grams of creatine monohydrate daily to enhance cellular energy (ATP regeneration) and provide neuroprotective benefits for the brain, with higher doses recommended for increased brain health.

22. Supplement with Omega-3 Fatty Acids

Take Omega-3s (EPA, DHA) as they are crucial anti-inflammatory agents that improve cell membrane fluidity and constitute 20% of the brain’s lipid component, vital for brain health and potentially ameliorating amyloid plaques.

23. Test Your Omega-3 Levels

Use a reliable Omega-3 Index test, such as OmegaQuant by Dr. Bill Harris, to measure omega-3s in red blood cells, which can guide supplementation and highlight dangerously low levels common in the population.

24. Consider Genetic Testing (APOE4)

Get tested for genetic risk factors like APOE4 to understand your predisposition to Alzheimer’s, as this knowledge can serve as a powerful motivator for adopting proactive lifestyle changes.

25. Prioritize Rest and Recovery

Ensure sufficient rest and recovery to allow your brain to clear amyloid beta proteins, which are produced in response to stress and inflammation and can build up without adequate downtime.

26. Reverse Heart Aging with Exercise

Engage in three to four hours per week of maximal aerobic training (Zone 3/4) to potentially reverse the age-related decline of your heart by 20 years, as shown in a study of 50-year-olds.

27. Improve VO2 Max for Life Extension

Increase your VO2 max, as every milliliter improvement is associated with a 45-day life extension, and moving from average to above-average fitness can add five years to your life.

28. Start Exercise Gently to Build Motivation

If currently inactive, begin with short, easy movements like a 10-minute walk or a gentle hill walk, as pushing too hard initially can demotivate you by reducing dopamine release.

29. Prevent Exercise Injuries

Take precautions to prevent exercise injuries, as they incur significant costs beyond direct pain, including fear of future activity, reduced movement during recovery, and prolonged delays in returning to baseline fitness.

30. Start Strength Training with Bodyweight

If sedentary, begin strength training with accessible bodyweight movements like push-ups or wall sits, or find beginner workouts online, as you don’t need a gym to build strength and muscle.

31. Consider Supplements for Racing Mind

Explore supplements like Ashwagandha, Turmeric, or GABA (Gamma-Aminobutyric Acid) to help downregulate cortisol, inhibit inflammatory pathways, and settle a racing mind, aiding in falling asleep.

32. Maintain and Grow Neural Connections

Actively engage in brain-supporting activities to ensure your brain cells are rich with connections, as Alzheimer’s is characterized by a decline in these neural networks, leading to cognitive symptoms.
