STRENGTHEN YOUR COGNITIVE RESERVE. RUN!
Maybe you’ve noticed names slip faster.
Maybe you walk into a room and wonder why.
Maybe you just want your mind to stay sharp as your body keeps moving.
Maybe you already know—a jog clears more cobwebs than a crossword.
Here’s the truth:
Running doesn’t just help the body.
It builds brain strength—your cognitive reserve.
Think of it like lifting weights. Muscle grows.
Run, and your brain grows connections.
Connections protect memory.
Connections fight back against disease.
How it Works—Without the Jargon
Running sparks the birth of new brain cells in areas tied to learning and memory.
It strengthens the connectors (synapses) that help thoughts stick.
It boosts blood flow and delivers oxygen—fuel for focus.
It triggers Brain-Derived Neurotrophic Factor (BDNF), often called “Miracle-Gro for the brain.”
The result? A stronger mind that resists decline. Research shows even modest exercise lowers dementia risk. The biggest gains come when inactive people simply start moving.
let’s run forever.
THE PERSONAL MILE
Every morning after my run, Tom heads to his car. Coffee in hand. His only quiet moment before a long day of caregiving. We’re the same age. He carries a different weight. His wife, Mindy, has Alzheimer’s.
If you’re reading this, help yourself. Don’t wait. Don’t overthink. Start small. Walk if that’s where you are. Run if you can.
Because here’s the plea: build your cognitive reserve now. Protect tomorrow by moving today.
TOOLBOX:
- Start Small – 35 minutes a week of moderate activity cut dementia risk by 41% in a 2025 Johns Hopkins study.
- Any Movement Counts – The biggest impact is going from nothing to something.
- Steady Beats Sporadic – Three brisk walks beat one big effort.
- Mix Scenery – Parks, trails, neighborhoods—variety engages the brain.
- Track Mood – Notice the lift after each run or walk. That’s your brain thanking you.
