Boost Attention & Memory with Science-Based Tools | Dr. Wendy Suzuki

Episode 73 May 23, 2022 1h 44m 14 insights
My guest is Dr. Wendy Suzuki, Ph.D., Professor of Neural Science and Psychology and (soon) Dean of New York University, whose research focuses on memory, attention, brain plasticity and simple, daily habits that can be leveraged to improve learning, focus, memory and cognitive ability. We discuss the role of cardiovascular exercise, weight training, deliberate cold exposure, meditation, verbal affirmations, sleep, and other behavioral practices for enhancing learning, mood and stress management, and increasing attention span. Dr. Suzuki shares the mechanisms by which these practices change our brain in order to improve cognitive function fast and reduce age-related cognitive decline.

Actionable Insights

1. Prioritize 7.5-8 Hours Sleep

Aim for 7.5 to 8 hours of sleep every night to improve willingness to tackle difficult tasks, enhance persistence, and ensure your brain works better for overall cognitive function.

2. Daily Cardiovascular Exercise

Engage in regular cardiovascular exercise, aiming for 30-45 minutes daily, or as frequently as possible, to release neurochemicals and BDNF, which improves mood, attention, and promotes the growth of new brain cells in the hippocampus.

3. Exercise Early for Brain Function

Perform your exercise early in the day, ideally right before you need to engage in important cognitive work, to maximize immediate benefits like improved mood, prefrontal function, and reaction time for up to two hours.

4. Daily 10-12 Minute Meditation

Practice a 10-12 minute guided body scan meditation daily to significantly decrease stress response, improve mood, and enhance cognitive performance by training focus on the present moment.

5. Optimal Hydration & Electrolytes

Dissolve one packet of Element electrolytes in 16-32 ounces of water and drink it first thing in the morning, and also during physical exercise, to ensure proper hydration and adequate electrolytes vital for optimal brain and body function.

6. Foundational Nutritional Support

Take an all-in-one vitamin-mineral probiotic drink (like Athletic Greens) once or twice a day to cover basic nutritional needs, address deficiencies, and support microbiome health, which is crucial for immune system, brain, and mood regulation.

7. End Showers with Cold Blast

Finish every morning shower with a big blast of cold water to increase adrenaline, epinephrine, norepinephrine, and dopamine, leading to improved mood, alertness, and a lasting feeling of awakenedness.

8. Make Information Memorable

To enhance memory formation, leverage novelty (newness), repetition, association (linking to known information), and emotional resonance (making it funny, surprising, happy, or sad).

9. Increase Exercise Gradually

If currently exercising less than 30 minutes per week, start with 2-3 times a week of 45-minute cardiovascular exercise (e.g., spin class) to improve mood, body image, motivation, attention, and hippocampal-dependent memory.

10. Maximize Exercise Frequency

If already exercising 2-3 times a week, increase cardiovascular exercise frequency up to seven times a week if possible, as every additional session improves mood (lower depression/anxiety) and hippocampal function.

11. Cultivate Positive Mindset

Learn about the positive effects of behaviors like stress and exercise to cultivate a positive mindset, as your beliefs about a behavior can physiologically impact its outcomes and lead to greater benefits.

12. Practice Positive Self-Affirmations

Regularly practice positive self-affirmations, ideally spoken aloud (e.g., ‘I’m strong,’ ‘I’m inspired’), to counteract negative inner dialogue, improve mood, and build a positive self-image.

13. Practice Tea Meditation

Engage in a 45-minute tea meditation, meditating over the brewing and drinking of tea, as a specific practice for focus and mindfulness.

14. Utilize Free Online Resources

Leverage free online resources like YouTube for guided meditations or exercise routines if you don’t want to join classes or prefer self-guided practice.
