Why Wendy Suzuki Exercises for 30 Minutes Every Morning
Wendy Suzuki explains that her daily 30-minute workout releases a "bubble bath" of neurochemicals and sharpens the prefrontal cortex, preparing her brain for work. She also says the same time every day is about building a habit that sticks.
- •Movement releases dopamine, serotonin, noradrenaline and growth factors
- •Prefrontal cortex function gets sharper after exercise
- •She exercises first thing to feel happy, motivated and focused for work
- •30 minutes every day built a lasting habit during the pandemic
The Tenure Years, a Peru Trip and a Wake-Up Call
Suzuki describes working nonstop toward tenure with no social life or movement, and being unhappy. A river rafting trip in Peru showed her she was the weakest person there, which sent her to the gym and then back to the research literature.
- •Six-year tenure pressure led her to only work and eat takeout
- •She felt unhappy despite working hard
- •The Peru trip made her realize how weak she was
- •A hip hop dance class made her feel good even though she was bad at it
- •Research shows regular movement can be as effective as some common antidepressants
Better Writing and a Shift in Research Focus
A year and a half into regular exercise, Suzuki noticed her grant writing was flowing better. This led her to shift her research from memory to the effects of exercise. Rangan reflects on how outward success can hide unhappiness.
- •She realized her writing improved after exercise was the only change she had made
- •Exercise helps the hippocampus (memory) and focus
- •She moved her research from memory to exercise
- •Rangan notes success and unhappiness can coexist
Creativity, New Courses and Her First Book
Suzuki explains how exercise growth factors reach the hippocampus, which also supports imagination. After she started working out she created courses that brought exercise and artists into the classroom, which led to her TED Talk and her first book.
- •Growth factors help new hippocampal cells grow
- •The hippocampus recombines memories, supporting imagination
- •She trained as an exercise instructor and created the course Can Exercise Change Your Brain
- •She created Art Meets Brain with artists and dancers
- •The TED Talk and Healthy Brain, Happy Life followed
How Little Exercise Is Enough: 10 Minutes and Four-Minute Hacks
Responding to Rangan's questions about time of day and the four-minute hacks, Suzuki says the 30 minutes does not have to be in the morning. She cites 10 minutes of walking as the minimum shown to improve mood and lower anxiety. Rangan shares his own five-minute strength routine and a colleague who thought less than an hour didn't count.
- •Any time of day works for movement
- •Four-minute hacks were chosen because they are doable
- •10 minutes of walking reduces negative mood states
- •Rangan does a five-minute strength workout while his coffee brews
- •Short bouts matter more than an all-or-nothing approach
Fitness Midlife and Dementia: The Swedish Women Study
Suzuki describes a 44-year correlational study of Swedish women in which those who were high-fit in midlife staved off dementia by nine years. She stresses that it is correlational but consistent with the neuroscience on the hippocampus and prefrontal cortex.
- •Study followed 300 Swedish women for 44 years
- •High-fit women staved off dementia by nine years
- •The study is correlational, not causal
- •Exercise supports the hippocampus and prefrontal cortex, which are sensitive to aging
BDNF and New Brain Cells in the Hippocampus
Suzuki explains that BDNF is a growth factor that helps new brain cells grow in the hippocampus. Only the hippocampus and olfactory bulb grow new cells in adulthood, and exercise stimulates this in the hippocampus.
- •BDNF stands for brain-derived neurotrophic factor
- •It facilitates synapse formation in development and adulthood
- •Only two brain areas grow new cells in adulthood
- •Exercise triggers growth factor release that reaches the hippocampus
- •Moving your body is her "secret tool"
Memory, Identity and Patient HM
Suzuki explains that memory is about our sense of self, not just remembering where the keys are. She tells the story of patient HM, whose hippocampi were removed in the 1950s, leaving him unable to form new memories.
- •Memory defines our personal story
- •HM had both hippocampi removed to treat severe epilepsy
- •He could not form new memories for facts and events
- •Childhood memories and language skills remained intact
Long-Term Potentiation and Exercise
Suzuki defines long-term potentiation as a hippocampal synapse change underlying memory formation. She explains that exercise increases neuron numbers and LTP, and that new hippocampal neurons are readily recruited into memory circuits, as in rats with running wheels.
- •LTP was discovered in the hippocampus in the 1970s
- •Synapse changes after experience underlie forming a new memory
- •Exercise increases hippocampal neurons and LTP
- •New neurons are like active teenagers joining memory circuits
- •Exercised rats do better on spatial memory tasks
Chronic Stress, the Hippocampus and Brain Plasticity
Suzuki explains that the hippocampus is vulnerable to chronic stress because of its many cortisol receptors. She says a little stress helps, but chronic stress prunes and kills hippocampal cells. Brain plasticity means neurons can regrow and new ones can form.
- •PTSD is associated with a smaller hippocampus
- •The hippocampus has many cortisol receptors
- •A little stress helps performance; chronic stress is damaging
- •Rangan sees more memory complaints in people in their 30s and 40s
- •Neurons can get bigger again, and new ones can form in the hippocampus
The Prefrontal Cortex, Working Memory and Attention
Suzuki describes the prefrontal cortex's role in working memory and in shifting and focusing attention. She links this to meditation as an exercise of the prefrontal cortex and says a 30-minute workout improved attention shifting for at least two hours in her lab.
- •Working memory is scratchpad memory
- •Ordering tasks like baking depends on the prefrontal cortex
- •Meditation trains focusing attention where you choose
- •One 30-minute workout improved attention for at least two hours
Alcohol, Sleep and the Brain
Suzuki explains that alcohol acts as an inhibitory neurotransmitter and disrupts sleep, which is vital for brain function. One glass of wine won't kill brain cells, but cutting back helps brain regeneration.
- •Alcohol acts as an inhibitory neurotransmitter
- •It may bring sleep faster but disrupts sleep quality
- •Long-term sleep deprivation is lethal in animals
- •Even a little alcohol can have negative effects on sleep
Anxiety as a Superpower: Turning What-Ifs into To-Dos
Suzuki explains why anxiety is protective in evolutionary terms and how to turn it into a tool. A "what if" list shows what you care about, and converting it into a to-do list brings productivity.
- •Anxiety evolved to protect us from physical danger
- •Modern triggers like email and news still release the stress response
- •The first step is to turn the volume down to a controlled level
- •What-if lists reveal what you value
- •Taking action on a to-do list relieves anxiety
Reframing Anxiety and Its Link to Exercise
Suzuki discusses how mindset shifts, such as treating asking questions as a job, can change anxiety. She and Rangan describe anxiety as a signal to learn from, and she explains that 10 minutes of walking directly lowers anxiety through neurochemical release.
- •Reframing changed her shy classroom experience
- •Uncomfortable emotions are warning systems
- •Anxiety can be thought of as a little kid saying "Project over here"
- •10 minutes of walking decreases anxiety
- •An optimistic outlook can be cultivated
Meditation, Tea Ritual and Music, Plus Closing Advice
Suzuki covers meditation research, including EEG studies of Tibetan monks, and explains how her tea meditation made the habit stick. She describes a study of music that gives people goosebumps, then advises listeners to start small with 10 minutes of walking or a short breath meditation.
- •Monks showed very high gamma activity during meditation
- •Meditation improves mood and focus like exercise
- •Her tea meditation made the habit stick
- •Music that gives goosebumps activates brain reward areas
- •Her closing advice is to start small and expect hope
