Accelerate Learning & Increase Cognitive Capacity | Dr. Tommy Wood

Key wellness strategies, self-care techniques, and productivity tips

Exercise to “open the window” for learning (neuroplasticity)

• Do both aerobic + resistance training (they target different brain structures):
  • Aerobic / cardio → more associated with gray matter / hippocampal benefits and memory support
  • Resistance training → more associated with white matter improvements and executive-function gains
• Consider high-intensity intervals (HIIT) in addition to Zone 2:
  • Norwegian 4x4 protocol example:
    • 4 minutes at ~85–95% max heart rate
    • 3-minute rest
    • repeat 4 times
    • 3x/week for ~6 months
  • Key takeaway from the described study: HIIT improved fitness similarly to Zone 2, but showed better hippocampal function/structure, with benefits lasting for years.
• Avoid “maxing out” right before deep cognitive work:
  • Hard training can temporarily impair performance afterward—aim for manageable intensity so you can still do focused cognitive work.
• Pre-learning exercise for immediate focus:
  • Best-supported immediate effect described: ~20–30 minutes of moderate activity (e.g., a jog) to boost arousal and improve cognitive performance afterward.

Pick learning inputs that are both challenging and engaging

• Use novelty + challenge together:
  • Don’t only rely on familiar skills (“use it or lose it”); add new cognitive or skill demands.
• Prefer “broad transfer” activities over narrow brain training:
  • Online/digital brain training may improve a specific task but often doesn’t transfer well to daily life.
  • More complex “human” skills may engage multiple networks and generalize better.

High-potency plasticity inducers (practical examples)

• Skill learning is especially potent when it includes:
  • Motor + cognitive components
  • Social interaction
  • Multi-sensory processing (e.g., timing, rules, feedback)
• Examples emphasized:
  • Dancing (especially ballroom / line dancing: social + learning + physical)
  • Ball/board/team sports
  • Martial arts (with an emphasis on safety—avoid repeated facial impacts)
  • Skateboarding with helmet use
  • Language learning
  • Some creative arts (e.g., visual/creative learning that engages attention/focus networks)

The “clutch state” concept (performance/learning without comfort)

• Instead of chasing “flow” all the time, aim for a clutch state:
  • Optimal arousal where performance is excellent, but it still feels like hard work (some friction/challenge).
• Practical implication:
  • Learning improves when you work at the edge of your capability, not in effortless comfort.
  • If something is too hard and you fail repeatedly, it can backfire—choose difficulty where progress is visible.

How to structure practice for maximum learning

• Time-on-task chunks for deep work:
  • For difficult cognitive/motor training, focus sessions are often best as ~60–90 minutes, sometimes 2 sessions per day.
  • Longer uninterrupted “grinds” tend to reduce output after deadlines or as fatigue builds.
• Pomodoro-like chunking:
  • Even though strong direct studies weren’t claimed, the 25-min work / 5-min break pattern was discussed as compatible with sustainable deep-focus cycles.

Attention & productivity: reduce interruptions, manage “attentional break expectation”

• Eliminate distractions for true deep work:
  • Put phone in another room
  • Close messaging tools (Slack/Teams/email)
  • Turn off notifications
• Meditation may help, but:
  • It can be easy to drift if you’re not used to sustained attention—use a timer and expect mind-wandering.
• Use friction intentionally:
  • If you’re stuck, switching projects can help—work with 2–3 active projects rather than forcing one that isn’t clicking.
• Don’t forget recovery for cognition:
  • Overtraining can leave you too exhausted to benefit mentally—your “felt” recovery matters.

Nutritional strategies for cognitive health (diet + supplement “threshold” thinking)

• Mediterranean-style patterns as the baseline:
  • Seafood, vegetables, berries, whole grains
  • Emphasize nutrient density (not necessarily a single magic food)
• Three diet levers emphasized:
  • Energy balance (not too little, not too much)
  • Nutrient sufficiency (vitamins/minerals/macros)
  • Overall dietary pattern
• Energy excess and metabolic issues can reduce brain support:
  • Chronic caloric excess and chronic restriction are both linked (in described research) to smaller brain volume.
• Supplements: focus on deficiency/insufficiency rather than “more is better”:
  • Testing encouraged:
    • Vitamin D
    • Iron/hemoglobin
    • Omega-3 status
    • B vitamins (e.g., markers via homocysteine)
  • Key philosophy: “Don’t be deficient”—that may be sufficient for most people.
• Omega-3 nuance:
  • Body fat can act as a reservoir; inconsistent day-to-day intake may still be okay if you regularly eat seafood.
  • Trials finding no benefit may be because participants weren’t deficient to begin with.
• Creatine highlighted as one of the strongest safe + evidence-backed options:
  • Mentioned as safe even at higher doses in older/frail groups.
• Magnesium:
  • Mentioned as important; suggested form: magnesium glycinate (for bioavailability).
• Why trials sometimes fail:
  • Nutrient synergies may matter—e.g., omega-3 and B vitamins (via homocysteine reduction) may only show benefits when baseline status is low for both.

Sleep/mental recovery and “how you feel” tracking

• Tracking subjective state matters:
  • “How good do you feel?” (felt motivation/recovery) predicts performance better than many physiological metrics.
• Caution about dissociation from stimulants:
  • Some stimulants can make you feel more capable while performance (errors, cognition) worsens—exercise may be more reliable because it doesn’t create the same mismatch.

Stress reframing (important for long-term brain health)

• Acute stress can drive adaptation:
  • The talk contrasted intermittent adaptive stress (exercise/learning challenge) with chronic stress that erodes sleep and increases disease risk.
• Practical cue:
  • If stress is eroding sleep, that’s a sign to adjust.

Safety note re: concussion recovery (mild/moderate)

• First: medical evaluation and rule out serious injury.
• Then, described “low-risk/high-potential” supports:
  • Prevent hyperthermia (avoid getting too hot; don’t ignore fever)
  • Blood sugar regulation: avoid refined sugary carbs
  • Avoid alcohol (hurts sleep)
  • Avoid caffeine acutely (stimulates + sleep disruption)
• Possible supplements with some evidence mentioned:
  • Creatine
  • Magnesium (form discussed)
  • Omega-3
  • Choline (CDP-choline/citicoline) for acetylcholine support
  • Boswellia (most evidence among some anti-inflammatory options mentioned)
• Return to activity:
  • Resume sub-symptom aerobic activity as soon as tolerated; use structured return-to-play protocols.
