Essentials: Tools to Boost Attention & Memory | Dr. Wendy Suzuki

Key Wellness & Productivity Strategies (Dr. Wendy Suzuki)

Core Principles of Memory (How to Make Information Stick)

• Novelty: New experiences and events draw attention and improve memorability.
• Repetition: Re-encountering information strengthens recall.
• Association: Linking new information to existing knowledge and people makes it easier to remember.
• Emotional resonance: Strong emotions (happy/sad/surprising/threatening) amplify memory formation via the amygdala → hippocampus interaction.

The “Hippocampus” and Why It Matters

• The hippocampus supports encoding long-term memories and helps you form your “personal history.”
• It also supports imagination and future planning by enabling flexible association of information.

Exercise as a Brain Tool to Improve Attention + Memory

Recommended routine

• 30–45 minutes of aerobic exercise daily
  • Dr. Suzuki personally uses video workouts and may add stretching.
• Any cardio that raises heart rate helps
  • Power walking can be sufficient for cognitive/mood benefits.
  • Variety (weights, kickboxing-style workouts) is fine as long as you meet intensity/heart-rate targets.

Minimum effective dose (for mood)

• ~10 minutes of walking outside can shift mood (a “neurochemical” effect).

Mechanism: How movement supports learning

• Regular exercise releases neurochemicals that support mood:
  • dopamine, serotonin, noradrenaline
• Particularly important: BDNF (brain-derived neurotrophic factor)
  • BDNF supports growth/maintenance of hippocampal connections
  • It may also support new neurons in humans, though this area is still actively researched and debated.

What Exercise Improves (Acute Effects)

After one aerobic session (~30–45 minutes), benefits include:

• Mood boost
• Improved prefrontal attention/executive function (e.g., Stroop-type tasks)
• Faster reaction time
• Dr. Suzuki’s reported outcomes: reduced anxiety/depression/hostility
• Effects can last up to ~2 hours (in one study)

Long-Term Exercise Dose-Response

• Consistency over decades matters.
  • A Swedish longitudinal study found that higher fitness in midlife was associated with more years of good cognition later.
• Lower-fit adults (30s–mid-50s):
  • 2–3 cardio sessions/week (spin class style; ~45 minutes with warmup/cooldown) improved mood and hippocampus-dependent memory performance.
• Mid-fit people increasing training:
  • “Every drop of sweat counted”
  • Increasing from ~2–3x/week up toward 7x/week improved mood and hippocampal memory over ~3 months.

Practical Mental Training: Affirmations Paired With Movement

• Dr. Suzuki discussed IntenSati, which combines:
  • kickboxing/dance/yoga/martial-arts-style movement
  • positive spoken affirmations during each action
• Claimed benefits:
  • improves mood and self-image
  • builds a habit of more supportive self-talk
  • can surface negative self-talk patterns

Meditation: A Simple “Minimum Viable” Practice for Attention & Stress

• Daily time: about 10–12 minutes
• Type: guided body-scan meditation
• Reported outcomes after weeks of daily practice:
  • lower stress response (improved performance on stress tests)
  • better mood
  • improved cognitive performance
• Dr. Suzuki’s interpretation:
  • it builds the ability to focus on the present moment, reducing rumination about the past and fear about the future

Dr. Suzuki’s Top 3 Attention Boosters (“Today” Toolkit)

1. Exercise — supports prefrontal attention + hippocampal memory via BDNF and related pathways
2. Meditation — 10–12 minutes body scan to strengthen present-moment focus and reduce stress
3. Sleep — critical for attention, creativity, learning, and overall brain performance
