- The gym that raised test scores
Picture a school district near Chicago where students run a mile before their first lesson, wearing heart rate monitors and graded on effort rather than speed. The district's science scores rose to near the top of an international ranking, and the school became one of the fittest in the country.
- Fertiliser for your neurons
Here is the mechanism. When you exercise, your brain releases more of a protein that Ratey nicknames brain fertiliser, formally called BDNF, brain-derived neurotrophic factor.
- Stress, anxiety, and the moving cure
Ratey argues that stress is not a mental problem separate from the body; it is the body's alarm system stuck on. Exercise works because it is a controlled dose of stress.
- Attention, addiction, and the ageing brain
The same chemistry explains why movement helps in three more areas. People with attention difficulties often have low dopamine and norepinephrine in the frontal lobes; a hard workout raises both, which is why a restless child settles after running around and why Ratey suggests exercise before demanding mental work.
- The prescription for a better brain
What should you actually do? Ratey's guidance is practical.
- Put it to work
Start this week by moving before your hardest mental task: a 20 minute brisk walk or cycle before you open the textbook or the spreadsheet, and notice how the first hour feels. Schedule four sessions of at least 30 minutes of cardio and treat them like appointments you cannot cancel.
