Regular exercise releases growth factors. These growth factors benefit the hippocampus, helping it grow new brain cells, leading to improved memory. In the prefrontal cortex, while not growing new cells, the axons (outputs of cells) function better and work more efficiently with regular exercise.
The video recommends as little as 10 minutes of walking. This is effective because even this short duration releases a portion of the "neurochemical bubble bath" – dopamine, serotonin, endorphins, etc. – resulting in improved mood, reduced depression and anxiety.
According to Wendy Suzuki, exercising in the morning makes it harder for other things to interfere, resulting in less interruption to the workout. Additionally, she finds that starting her day with exercise results in a happier brain that is better able to focus attention and respond more quickly throughout the day.
Short-term benefits of exercise on the prefrontal cortex include improved ability to shift and focus attention, and faster reaction and response times.
This video explores the science behind the brain benefits of exercise, specifically focusing on even short walks. Wendy Suzuki explains the "neurochemical bubble bath" effect of movement on the brain, highlighting both short-term mood boosts and long-term structural changes in brain areas crucial for memory and attention. She also discusses strategies for maintaining motivation and finding the best time of day to exercise.
The video doesn't specify separate benefits to the prefrontal cortex from morning vs. other times of day for workouts. It states that exercise in general improves the function of the prefrontal cortex, enhancing attention and focus. Suzuki's personal experience is that morning workouts help her maintain better focus throughout the day, but this is anecdotal, not a specific effect of morning exercise on the prefrontal cortex itself.
