Essentials: Tools to Boost Attention & Memory | Dr. Wendy Suzuki
Dr. Wendy Suzuki, PhD, discusses simple daily habits to improve focus, memory, and cognitive performance. She explains how exercise directly enhances brain function and mood, and how practices like meditation, verbal affirmations, and sleep positively influence stress regulation.

7 Key Concepts
Hippocampus
A key brain structure, shaped like a seahorse, crucial for forming new long-term memories for facts and events. It also plays a vital role in imagination by associating existing memories in new ways, essentially defining our personal histories.
One-Trial Learning
A phenomenon where a memory can be formed very quickly, often after a single, highly emotionally salient event. This is linked to the brain's protective function, remembering potentially dangerous situations for survival.
Brain-Derived Neurotrophic Factor (BDNF)
A growth factor released particularly during aerobic exercise that goes directly to the hippocampus. It helps brand new brain cells grow in the hippocampus, contributing to a 'bigger, fatter, fluffier hippocampus'.
Neurogenesis
The process of new neurons being born and added to the brain. Studies suggest this occurs in the adult human hippocampus, even into old age, and can be stimulated by factors like exercise.
Myokine
A protein released by striated muscles during exercise. It can pass the blood-brain barrier and stimulate the release of BDNF in the brain, contributing to neurogenesis and cognitive benefits.
Beta-hydroxybutyrate
A ketone released by the liver during exercise. This ketone also passes the blood-brain barrier and acts as another stimulant for BDNF production in the brain.
IntenSati
A form of exercise that combines physical movements (like kickboxing, dance, yoga) with positive spoken affirmations. It aims to boost mood and brain function by integrating physical activity with self-declarations.
12 Questions Answered
Things become memorable due to novelty (something new), repetition, association (linking to known information), and emotional resonance (happiest, saddest, funny, or surprising moments).
The hippocampus is crucial for forming new long-term memories for facts and events, and for imagination by associating existing information in new ways for past, present, or future scenarios.
The brain has an evolutionarily developed protective function that leverages the amygdala to make the hippocampus work better, stamping in memories of potentially dangerous or very scary situations for survival.
A single 30-45 minute aerobic exercise session consistently provides a mood boost, improved prefrontal function (like shifting and focusing attention), and improved reaction time.
The immediate effects of a single exercise session, such as improved mood and cognitive function, have been shown to last for up to two hours.
The neuroscience data suggests that the best time to exercise is right before you need to use your brain in the most important way, which for most people is in the morning.
Longitudinal studies indicate that women who were highly fit in their forties gained nine more years of good cognition later in life compared to low or mid-fit women, suggesting long-term protective effects.
Just 10 minutes of walking outside can shift your mood by releasing a 'neurochemical bubble bath' of dopamine, serotonin, and noradrenaline.
Low-fit individuals in their 30s to mid-50s can see cognitive benefits from two to three 45-minute cardiovascular workouts per week, including improved mood, body image, motivation, and hippocampal memory.
Yes, positive affirmations, especially spoken aloud, can change mood, foster a habit of positive self-talk, and help counteract negative thoughts about oneself.
As little as 10-12 minutes of daily guided meditation (like a body scan) can lead to significant decreases in stress response, improved mood, and better cognitive performance.
The top three tools for improving attention and overall core cognitive functions are regular exercise, consistent meditation, and sufficient sleep.
11 Actionable Insights
1. Top 3 Pillars for Enhanced Brain Function
Consistently integrate exercise, meditation, and sufficient sleep into your daily routine to directly improve attention, creativity, learning, memory retention, and overall cognitive performance.
2. Daily Aerobic Exercise for Brain Health
Engage in 30-45 minutes of daily aerobic exercise, ensuring your heart rate is elevated, to release neurochemicals that boost mood and brain-derived neurotrophic factor (BDNF) which promotes new brain cell growth in the hippocampus, enhancing memory and protecting against cognitive decline.
3. Optimize Exercise Timing for Cognitive Peak
Schedule your exercise session right before you need to perform cognitively demanding tasks, ideally in the morning, to leverage the immediate benefits of improved mood, focus, and faster reaction times, which can last up to two hours.
4. Minimum Cardio for Low-Fit Individuals
If currently exercising less than 30 minutes per week, commit to 2-3 sessions per week of 45-minute cardiovascular exercise (including warm-up/cool-down) to significantly improve mood, body image, motivation, attention, and hippocampal memory.
5. Increase Cardio for Enhanced Brain Benefits
For those already moderately fit, increasing your exercise frequency, even up to daily sessions, can lead to further improvements in mood (lower depression/anxiety, higher positive affect) and hippocampal memory function.
6. Daily Short Meditation for Stress & Focus
Practice 10-12 minutes of daily guided body scan meditation to significantly decrease stress responses, improve mood, and enhance cognitive performance, particularly by cultivating present moment focus.
7. Make Information Memorable
To improve memory encoding, leverage the brain’s natural mechanisms by introducing novelty, employing repetition, creating associations with existing knowledge, and attaching emotional resonance to the information you wish to remember.
8. Combine Exercise with Positive Affirmations
Integrate positive spoken affirmations (e.g., ‘I am strong now’) into your exercise routine to amplify mood benefits, cultivate a positive self-image, and counter negative self-talk, in addition to the physical and cognitive boosts from movement.
9. Quick Mood Boost with a 10-Minute Walk
When time is limited, take a minimum of 10 minutes to walk outside, as this simple movement can quickly shift your mood by releasing beneficial neurochemicals like dopamine, serotonin, and noradrenaline.
10. Cultivate Present Moment Focus with Meditation
Regularly practice meditation to build the habit of focusing on the present moment, thereby reducing anxious future thinking and rumination on past events, allowing for greater enjoyment and engagement with your current experience.
11. Long-Term Fitness for Cognitive Longevity
Sustain a high level of physical fitness throughout your adult life, especially starting in your forties, to potentially gain years of good cognitive function and build a ‘bigger, fatter, fluffier hippocampus’ that can buffer against age-related cognitive decline.

Every drop of sweat counted.
Dr. Wendy Suzuki
You're not locked into that fearful future thinking that so many of us have, or that, that, that just reliving of a terrible past, but you could enjoy, enjoy the present moment.

3 Protocols
Minimum Exercise for Mood Shift
Dr. Wendy Suzuki- Walk outside for 10 minutes.
Minimum Exercise for Cognitive Benefits in Low-Fit Adults
Dr. Wendy Suzuki- Engage in cardiovascular exercise 2 to 3 times per week.
- Each session should be 45 minutes long, including 5 minutes for warm-up, 35 minutes of intense work, and 5 minutes for cool-down.
Brief Daily Meditation for Stress & Cognition
