How Speed Math Improves Cognitive Health
Health & Math
Jan 28, 2026
We often think of math as a tool for engineering or accounting, but current research suggests it’s one of the most effective exercises for maintaining long-term brain health and slowing cognitive decline.
Building Cognitive Reserve
"Cognitive Reserve" is a concept used to explain why some people maintain sharp minds into their 90s. It’s essentially the brain’s ability to improvise and find alternate ways of getting a job done. Engaging in rapid mental arithmetic forces the brain to utilize multiple neural networks—visualizing the numbers, applying rules, and executing calculations—all at once. This multi-threaded tasking is like lifting weights for your neural pathways.
Math vs. Crosswords
While crosswords and Sudoku are popular, speed math offers a unique benefit: Time Pressure. Time pressure triggers the release of norepinephrine, a chemical that enhances focus and memory. By solving math problems quickly in a game like Math Rush, you aren't just practicing arithmetic; you're training your brain to remain calm and efficient under pressure.
Neuroplasticity in Action
Every time you learn a new mental math trick or beat your high score, your brain strengthens its synaptic connections. Studies have shown that even a few minutes of daily math practice can lead to measurable improvements in Working Memory and Executive Function. This helps with everything from remembering grocery lists to making quick decisions at work.
