How does exercise change your brain before you even notice it?

In “The Brain-Changing Benefits of Exercise,” neuroscientist Wendy Suzuki argues that physical activity has immediate, long-lasting, and protective effects on the brain. Drawing from her own shift from memory research to exercise neuroscience, she explains how workouts boost mood chemicals, sharpen attention, grow and strengthen the hippocampus and prefrontal cortex, and may delay the impact of aging-related cognitive decline and diseases like dementia.
