Episode 142: Dr. Tommy Wood: The Science of Brain Performance Optimization
Release Date: February 26, 2026
Guest: Dr. Tommy Wood, Associate Professor of Pediatrics and Neuroscience, University of Washington; Head of Motorsport Science, Hintsa Performance; Chief Science Officer, Food for the Brain; Co-founder, Better Brain

Episode Overview

This episode centers on the latest evidence-based strategies for maintaining and improving brain performance across the lifespan. Dr. Darshan Shah interviews Dr. Tommy Wood, who brings both research and real-world performance experience from neonatal brain injury to elite Formula 1 racing. Discussion ranges from Dr. Wood’s foundational "3S Model" for brain health to specific protocols for learning, sleep, nutrition, brain injury, and the interface between metabolic and cognitive health.

“Most people assume memory loss and mental decline are inevitable with age, but the science tells us a very different story. The brain doesn't need comfort, it needs challenge.” — Dr. Darshan Shah (00:51)

Key Discussion Points and Insights

1. Dr. Tommy Wood’s Background & Approach

Multi-disciplinary expertise spanning neonatal brain injury, dementia prevention, and elite sports neuroscience.
Insights are derived from scientific research, clinical data, and hands-on work with F1 drivers (03:01).
Quote: “I wear a few different hats that are related to the brain...I help oversee some performance programs [for F1 drivers] as well.” — Dr. Tommy Wood (03:02)

2. The "3S Model" for Brain Health

Stimulus: How the brain is challenged and engaged through learning and skill acquisition.
Supply: The metabolic, circulatory, and nutritional support systems (blood flow, nutrients, metabolic health).
Support: Recovery processes including sleep, hormone balance, and reduction of stress/inflammation.
Emphasizes the interconnectedness of these three domains for both brain function and adaptation.
Quote: “You don’t get stronger in the gym. You get stronger when you sleep or recover... The same principles apply to the brain.” — Dr. Tommy Wood (08:01)

3. Stimulus: Learning, Skill Development, & Cognitive Headroom

Complex, high-challenge, focused learning is protective for the brain.
Motor skills (dance, sports), creative arts, languages, and music activate wide neural networks and “cognitive headroom.”
Rule of thumb: 30–90 minutes of focused skill-building, 2–3 times per week, with days off for consolidation.
Passive or repetitive brain games (“rote activities” like Sudoku) are less effective than immersive, challenging skills (15:27–17:55).
Quote: “The modern human brain is both understimulated and overstimulated at the same time.” — Dr. Tommy Wood (12:20)
Quote: “Brains that keep adapting stay younger longer.” — Dr. Darshan Shah (74:54)

4. Work, Focus, and Recovery Structure

Modern “knowledge work” creates cognitive overload via multitasking and constant low-value stimulation.
Productivity, focus, and stress resilience improve with deliberate breaks: 5-minute resets (mindfulness, comedy clips, nature exposure).
Quote: “If you can restructure your work so that you get some focused work done...and give yourself some breaks in between, that allows you to recover and come back with more vigor.” — Dr. Tommy Wood (15:47)

5. Repetition vs. Recovery in Learning

The “10,000 hours” myth clarified: Skill mastery happens over time, but recovery is equally important.
Naps and rest after intense learning accelerate consolidation (28:38–28:57).
Quote: “Often, you are better off focusing on recovery rather than doing more reps.” — Dr. Tommy Wood (28:38)
For students: More benefit from spaced learning + rest than cramming (28:57).

6. Support: The Critical Role of Sleep

Sleep opportunity (adequate time in bed) is paramount; quality and regularity are next.
Focus on regular sleep timing to optimize circadian processes and REM/deep sleep.
Tools like blue-light glasses can act as “Pavlovian” cues for winding down (34:05–35:13).
Quote: “REM sleep happens at the end of the night. If you’re not getting enough total hours...you’ll get less REM. Sleep opportunity is what most people miss.” — Dr. Tommy Wood (31:38)

7. Supply: Nutrition, Metabolic & Vascular Health

Three pillars: Adequate energy (not too much, not too little), critical nutrients (vitamin D, omega-3s, B vitamins, iron, magnesium, zinc, polyphenols), and an overall dietary pattern (e.g., MIND/Mediterranean).
Avoid over-restriction—caloric adequacy is important for brain reserve.
Diet “Superfoods”: Berries (especially blueberries); sardines for creatine + omega-3s.
Pattern matters: Many approaches can fulfill core needs; not everyone requires “Mediterranean” foods specifically (40:39–45:02).
Ultra-processed foods avoidance is important but not always realistic for all populations—nutrient sufficiency sometimes aided by fortification (42:09–43:58).
Quote: “If there is a superfood for the brain, it’s probably berries... with a side of sardines.” — Dr. Tommy Wood (44:15)

8. Blood Flow & Hypertension

Hypertension is a major, often invisible, risk for cognitive decline.
Management via cardio exercise, adequate sleep, and, where needed, medication.
New devices (continuous BP monitoring) and modern medication can help maintain optimal blood pressure and reduce dementia risk (45:18–47:50).
Quote: “The closer you are to 120/70, the more protective it is not just for your heart health but also for your brain.” — Dr. Darshan Shah (47:06)

9. Brain Injury: Risk, Prevention & Recovery

Early life injury and home environment: Good support after even severe neonatal injury predicts better outcomes.
Traumatic Brain Injury (TBI): Accumulates neuroinflammation and raises later dementia risk—avoidance is essential, but recovery protocols are also critical.
Prevention: Protect against head injury in sports, especially youth; maintain strength to avoid falls in older adults (53:46).
Post-Injury Protocols:
- Creatine: Loading dose after concussion is beneficial; ongoing supplement for high-risk sports.
- Omega 3 fatty acids: 3-4g/day post-TBI reduces markers of brain injury.
- Choline: 500–1,000 mg CDP-choline may aid recovery.
- Other: BCAA & melatonin for sleep, berries for polyphenols.
- Heat management: Avoid fever and overheating after injury (58:54–59:37).
- Quote: “If you have a concussion... Creatine, omega-3s, and choline—those are the main ones.” — Dr. Tommy Wood (55:13)

10. Exogenous Therapies

Ketones: Possible benefit post-TBI, but more evidence needed (60:43–61:53).
Hyperbaric oxygen: Not recommended acutely, but potentially helpful for prolonged symptoms after injury (62:09–63:36).
Peptides (cerebrolysin): Some evidence for severe TBI, less for milder injuries (63:47–64:35).
NAD & nanotechnology: Promising early-stage research in animal models (64:41–65:45).

11. Diagnostics: Biomarkers & Monitoring

Emerging blood tests: Neurofilament light (NfL), tau protein (P-Tau217), and amyloid ratios—helpful for risk but their meaning is still evolving (66:33–70:16).
Functional markers: Homocysteine (for B vitamins), omega-3 index, vitamin D, and hemoglobin (for anemia/sleep apnea).
Personalized tracking: Some individuals find value in actionable metrics, but the main modifiable risks (BP, sleep, nutrition, activity) remain universally important.
Quote: “We know what the risk factors are for dementia in terms of lifestyle and environment... If you’re worried about your dementia risk, I can tell you to change those things without having to measure any blood biomarkers.” — Dr. Tommy Wood (68:32)

12. Book: The Stimulated Mind by Dr. Tommy Wood

Release: March 2026
Focus: User-friendly, actionable manual based on the 3S Model; guides readers through protocols for sleep, nutrition, cognitive challenge, workday structure, and stress management (72:55–74:11).

Notable Quotes & Memorable Moments

“Your brain declines because it stops being challenged, not because you’re aging.” — Dr. Darshan Shah (74:54)
“Every good athlete knows you don’t get stronger in the gym. You get stronger when you sleep or recover.” — Dr. Tommy Wood (08:01)
“Brains that keep adapting stay younger longer.” — Dr. Darshan Shah (74:54)
“If everybody could eat the way you first described, that would be great. But if not possible, sometimes food processing allows you to add protein and nutrients people might not otherwise get.” — Dr. Tommy Wood (43:58)

48:29 — Brain injury and recovery protocols
54:35 — Supplements & acute TBI support
60:43 — Exogenous ketones after injury
66:33 — Blood-based biomarkers for cognitive risk

Practical Protocols & Actionable Takeaways

For Everyday Listeners:

Never stop learning: Pick up a complex skill (language, instrument, dance) and practice a few times a week.
Prioritize sleep: Ensure you have enough “sleep opportunity” and stick to a consistent bedtime.
Eat for your brain: Focus on a nutrient-dense “pattern” (fiber, protein, healthy fats, berries), but don’t obsess over perfection.
Move and recover: Cardio for heart and vessel health, resistance training to avoid frailty and falls.
Monitor blood pressure: Address and treat hypertension early.
Take breaks: Reframe breaks as boosts for productivity and cognitive restoration.

For Injury or High-Risk:

Consider creatine, omega-3s, choline (and perhaps melatonin, B vitamins, and wild blueberries) post-concussion.
Regulate temperature and hydrate well after any brain injury.
Evaluate the risks and benefits of more advanced interventions with medical guidance.
