If I could prescribe one medication that reduced your risk of cognitive decline by 50%, I have a feeling we’d all be lining up for it.
Here’s the good news: it isn’t a medication.
It’s walking.
And not just walking around the grocery store with your cart or wandering from the couch to the kitchen (although every step counts).
New research found that adults in their 80s who maintained a faster walking pace were about 50% less likely to develop cognitive decline compared with others their age.
Researchers affectionately called these remarkable adults “super movers.”
Now before you think…
“Well, Alison, I haven’t power walked since the Reagan administration.”
Stay with me.
It’s Not About Being Fast. It’s About Keeping Moving.
One of the biggest misconceptions I hear as a pharmacist is that people think if they can’t exercise like they did in their 30s, there’s no point.
That couldn’t be further from the truth.
Your body doesn’t care if you’re training for a marathon. It celebrates every single time you move.
Every walk around the block.
Every lap through Costco.
Every stroll with your dog.
Every dance in the kitchen while dinner is cooking.
Movement is medicine.
Your Muscles Are Talking to Your Brain
Here’s something I wish everyone knew.
Your muscles aren’t just there to help you stand up or carry groceries. They’re actually one of the body’s largest communication systems.
When you walk, your muscles release chemicals that tell your brain to build and protect healthy brain cells. Exercise also increases a protein called brain-derived neurotrophic factor (BDNF), sometimes nicknamed “Miracle-Gro for the brain” because it helps support learning, memory, and healthy neurons.
As a pharmacist, I love when science confirms what we’ve suspected for years:
Healthy muscles help build a healthier brain.
Walking Works Like a Team Sport Inside Your Body
Every step sets off a chain reaction.
Your heart pumps more blood.
Your lungs work a little harder.
Your circulation improves.
Your muscles strengthen.
Your balance gets better.
And yes…
Your brain benefits too.
Walking supports several systems all at once, which is one reason researchers believe it’s such a powerful marker of healthy aging.
Our bodies were built to move.
When we stop moving, everything else slowly starts to slow down with us.
You Don’t Need Perfect Genes
Another part of the study really caught my attention.
Some of these “super movers” actually had brain changes that are often associated with Alzheimer’s disease, but they weren’t showing symptoms. Researchers believe staying active may help the brain remain resilient even when age-related changes occur.
Does genetics matter?
Absolutely.
But so do the little choices we make every day.
Sleep.
Good nutrition.
Managing stress.
Spending time with people we love.
And simply…getting up and moving.
My Pharmacist Prescription
If you walked into my pharmacy and asked me what you could do today to support your brain, here’s what I’d tell you:
Walk for 10 to 15 minutes after one meal each day.
Stand up every hour if you’ve been sitting.
Build a little strength with resistance bands two or three times a week.
Practice balance. Tai Chi and yoga are two of my favorites because they challenge both your body and your brain.
Don’t worry about being perfect. Worry about being consistent.
