Just 35 Minutes Could SAVE Your Brain

For years, I’ve told you exercise is non-negotiable for healthy aging.
As you age you must move more to protect your body and brain.
Now, groundbreaking new research confirms what I’ve been saying all along.
Exercise can slash your dementia risk—but with a surprising twist that eliminates your last excuse for not moving more.
Dementia is not a specific disease but rather a general term for the impaired ability to remember, think, or make decisions interfering with everyday activities. Dementia occurs when brain cells are damaged, affecting their ability to communicate with each other.
Alzheimer’s disease is the most common type, accounting for 60 to 80 percent of cases.
Dementia primarily affects older adults, and the most common symptoms are memory loss, confusion, difficulty communicating, and changes in personality and behavior.
But new research reveals just 35 minutes of weekly exercise can slash your risk.
Scientists at Johns Hopkins University found that when participants were even minimally activity (exercising for as little as five minutes daily or 35 minutes weekly), they were a stunning 41 percent less likely to develop dementia compared to those who were sedentary.
That’s right—as little as five minutes a day could make the difference between maintaining your mental sharpness and losing your precious memories.
Researchers found that those who engaged in 35 minutes of moderate-to-vigorous physical activity weekly had a remarkable 41 percent reduced dementia risk compared to inactive participants.
And the benefits only increased from there:
- 36-70 minutes weekly: 60 percent reduced risk
- 71-140 minutes weekly: 63 percent reduced risk
- More than 140 minutes: 69 percent reduced risk
So, how does exercise protect your brain?
Physical activity improves blood flow to the brain, reduces inflammation, stimulates the growth of new brain cells, and strengthens connections between neurons.
Exercise also helps control risk factors for dementia, including high blood pressure, diabetes, and obesity.
Some researchers believe regular activity might even directly reduce the buildup of harmful proteins in the brain that are associated with Alzheimer’s.
I understand that beginning an exercise routine can feel daunting, especially if you haven’t been active for years. But five minutes a day? That’s less time than brushing your teeth and getting dressed in the morning!
Here are some five-minute activities you can do to start protecting your brain today:
- A brisk walk around the block
- Dancing to a couple of your favorite songs
- Simple strength exercises like chair squats or wall pushups
- Climbing stairs in your home
- Gardening or yard work
- Vigorous house cleaning
You don’t need special equipment, a gym membership, or athletic ability to do any of them. This research truly eliminates every excuse for not exercising.
