Wendy Suzuki, a Professor of Neural Science and Psychology at NYU and author of 'Good Anxiety,' dives into the fascinating relationship between exercise and brain health. She discusses how physical activity boosts cognitive function and guards against age-related decline. Wendy breaks down the benefits of cardio versus strength training, and shares tips on sustaining exercise motivation. The chat also explores the brain benefits of sleep, meditation, and even the surprising advantages of anxiety—all wrapped up in practical advice for a healthier lifestyle.
Exercise significantly enhances cognitive function and protects against neurodegenerative diseases by promoting the release of key neurochemicals.
Sustaining motivation for exercise involves practical strategies such as starting with manageable sessions and integrating enjoyable activities into daily life.
Different exercise forms like cardio particularly boost brain health, while adequate sleep and mindfulness practices further complement cognitive function and emotional resilience.
Deep dives
The Cognitive Benefits of Exercise
Exercise significantly benefits brain health by promoting the release of neurotransmitters and neurochemicals, such as dopamine and serotonin, which enhance cognitive function. Engaging in physical activity increases levels of brain-derived neurotrophic factor (BDNF), a growth factor that supports the growth and maintenance of neurons in the hippocampus, critical for memory and learning. Regular exercise not only boosts immediate cognitive performance but also offers long-term protection against cognitive decline and diseases such as Alzheimer's. This highlights the importance of incorporating movement into daily routines for optimal brain function.
Sustaining Motivation to Exercise
Sustaining motivation for exercise requires practical strategies aimed at making physical activity enjoyable and accessible. Starting with short sessions, such as a 10-minute power walk, is an effective way to build a habit without overwhelming oneself. Engaging in activities that one already enjoys and incorporating them into daily life can further enhance motivation. Ultimately, the goal is to create a positive association with exercise to encourage consistency and long-term commitment.
Varieties of Exercise and Their Impacts
Different forms of exercise provide various benefits for brain health, with aerobic activities like cardio being particularly effective at enhancing cognitive functions and promoting growth in the hippocampus. While strength training is beneficial, the specific brain benefits are less understood compared to those resulting from aerobic exercise. Options such as power walking or engaging in group workouts can offer accessible ways to elevate heart rates without the need for traditional gym settings. It’s essential to remember that any movement counts, and individuals should find methods that suit their physical capabilities and preferences.
The Importance of Sleep and Mindfulness
Sleep plays a crucial role in maintaining brain health by allowing for the removal of metabolic waste that accumulates during the day. Adequate sleep supports cognitive functions, emotional regulation, and overall well-being. Additionally, practices like mindfulness meditation can enhance this effect by promoting relaxation and reducing anxiety. Together, sufficient sleep and mindfulness practices create a foundation for better brain function and emotional resilience, ultimately supporting a healthier lifestyle.
Understanding and Managing Anxiety
Anxiety is a common experience that can be reframed as a potential source of strength and empathy rather than merely a negative emotion. Techniques like deep breathing and joy conditioning can help individuals manage anxiety and transform it into a tool for personal growth. By recalling joyful memories or engaging in acts of kindness, people can create positive emotional associations that counterbalance their anxiety. Recognizing anxiety’s evolutionary purpose encourages a healthier perspective, allowing individuals to leverage it constructively in their lives.

This episode is part of our monthlong Do Life Better series.
We talk about:
How exercise not only enhances cognitive function but also protects against age-related cognitive decline and neurodegenerative diseases.
The difference between cardio and strength training
Whether it matters if you track your steps
How to sustain your motivation to exercise
And practical tips on how to start, restart or increase an exercise habit
We also talk about the brain benefits of sleep, meditation, and healthy eating (with a detour into ways to counteract the potentially unhealthy obsession with being healthy)
And finally, we talk about the counterintuitive benefits of anxiety
