Story at a Glance:
Alzheimer’s starts decades before symptoms appear, but lifestyle choices like exercise, diet, and sleep can significantly reduce your risk and protect your brain from cognitive decline.
Exercise, especially Zone 2 training, boosts blood flow to the brain, supports the growth of new brain cells, and helps fight off the plaques and tangles that lead to Alzheimer’s.
By prioritizing brain health today through small, actionable steps, you can protect your memory, improve cognitive function, and fight back against Alzheimer’s before it’s too late.
Today’s Newsletter Is Brought To You By Eight Sleep!
I’ve been using an Eight Sleep mattress for several years now, and it’s one of the best products I’ve ever purchased.
Their thermo-regulation technology — the bed gets colder or warmer throughout the night depending on individualized health metrics — helps me fall asleep faster, get higher-quality sleep, and wake up feeling energized.
The best part?
If you sleep with someone else in your bed you can split the mattress in half and change the settings. How cool is that!!

Neuro Athletes,
There’s a fear that many of us keep buried—a fear that creeps into our thoughts as we get older, one that’s hard to shake off. It’s the fear of losing our mind.
The idea that one day we might not recognize the faces of our loved ones or struggle to remember even the simplest details can be terrifying. Alzheimer’s and other forms of cognitive decline are cruel realities, and with so many affected globally, it's no surprise that this fear is deeply ingrained in our culture.
But fear doesn’t have to paralyze us. We can take action now to protect our brain and fight back against Alzheimer’s.
Today, I want to offer you both a reality check and a message of hope. There are scientifically proven steps we can take to maintain cognitive health and reduce our risk of Alzheimer’s. Let’s dive into how you can protect your brain for the long haul.
The Cold Reality of Alzheimer’s
Alzheimer’s affects over 6 million people in the U.S. alone, and this number is expected to grow as the population ages. It’s a progressive disease that slowly erodes memory, thinking skills, and eventually the ability to carry out simple tasks.
Here’s the truly unsettling truth: every 65 seconds, someone in the United States develops Alzheimer’s. That means in the time it takes you to read this email, another individual will begin their irreversible decline. But what’s even more terrifying is that by the time these symptoms start to show—by the time you or your loved ones notice the memory lapses, the confusion, or the inability to perform familiar tasks—the brain has already been deteriorating for years.
Alzheimer’s doesn’t strike out of the blue. The silent destruction begins decades earlier, as plaques and tangles build up in the brain, slowly choking off neurons and degrading cognitive function. It’s a disease that works in the shadows, eroding your most precious memories and abilities without you even realizing it—until one day, you can no longer recall the name of your child or follow the plot of your favorite book.
It doesn’t stop there. Alzheimer’s eventually strips individuals of the ability to speak, recognize faces, and carry out even the simplest tasks like dressing or eating. Loved ones watch helplessly as the person they knew slowly fades away. And once the disease takes hold, there is no cure—no way to reverse the damage already done.
As life expectancy continues to rise, so does the threat of Alzheimer’s. By 2050, the number of people living with the disease is expected to nearly triple, reaching 13 million in the U.S. alone. Imagine entire generations living in fear that they, too, will lose their mind before their body succumbs to the disease.
But here's the most critical part: Alzheimer’s starts long before the symptoms appear, and by the time those symptoms do show, it’s often too late to undo the damage. This is why early prevention is not just important—it’s absolutely crucial.
How Fear Can Drive Positive Action
Fear of cognitive decline can feel overwhelming, but it’s important to remember that fear can also be a powerful motivator. Instead of feeling helpless, you can channel that fear into action and arm yourself with strategies that actively reduce your risk of Alzheimer’s.
Here’s what we know: lifestyle factors play a massive role in brain health. The choices we make today—what we eat, how we exercise, how well we sleep—can either protect our brain or leave it vulnerable to decline.
5 Actionable Steps to Protect Your Brain Today
Exercise Regularly – Especially Zone 2 Training
Physical activity is one of the most effective ways to protect your brain. Studies show that moderate exercise, such as Zone 2 training, increases blood flow to the brain and promotes the growth of new brain cells in the hippocampus, the region most affected by Alzheimer’s.Action: Aim for 30 minutes of Zone 2 training—exercises like brisk walking or cycling—3-4 times a week. It’s one of the simplest ways to enhance cognitive function and protect against decline.
Adopt a Brain-Healthy Diet
What you eat has a profound impact on your brain’s health. A diet rich in antioxidants, omega-3 fatty acids, and anti-inflammatory foods can help stave off cognitive decline. The MIND diet—a combination of the Mediterranean and DASH diets—has been shown to lower the risk of Alzheimer’s by up to 53%.Action: Incorporate leafy greens, berries, fatty fish, nuts, and olive oil into your daily diet to support brain health.
Prioritize Sleep
Sleep is when your brain does its housekeeping. It clears out toxins, including beta-amyloid, the protein that forms Alzheimer’s plaques. Poor sleep over time can accelerate the buildup of these plaques, increasing the risk of cognitive decline.Action: Aim for 7-9 hours of quality sleep each night. Stick to a consistent sleep schedule, and create an environment that promotes deep, restorative sleep.
Challenge Your Brain
Just as you need to exercise your body, you also need to exercise your brain. Mental stimulation helps create new neural pathways, which can compensate for areas of the brain affected by Alzheimer’s.Action: Engage in activities that challenge your brain, such as learning a new skill, solving puzzles, or even socializing with friends. These activities help keep your brain sharp and resilient.
Manage Stress Levels
Chronic stress and high levels of cortisol—the stress hormone—have been shown to damage the hippocampus and impair memory. Managing stress is critical for maintaining cognitive function.Action: Practice stress-reducing techniques like mindfulness, meditation, or yoga. Even simple deep breathing exercises can have a positive impact on brain health.
Hope Through Science
We may not have a cure for Alzheimer’s yet, but the science of brain health is advancing rapidly. Researchers are discovering new ways to prevent cognitive decline and slow the progression of Alzheimer’s every day.
From cutting-edge studies on myokines—proteins released by muscles during exercise that protect brain cells—to new breakthroughs in personalized medicine, there is reason to be hopeful.
What’s clear is that early prevention is the best defense. By making small changes in our daily habits, we can significantly reduce our risk of cognitive decline and live longer, healthier lives.
The Path Forward
The fear of losing our minds is real, but it doesn’t have to define us. We have the power to fight back against cognitive decline by taking control of our brain health today. Exercise, nutrition, sleep, mental engagement, and stress management are all within our grasp—and they’re tools we can use to protect our most valuable asset: our brain.
So, if you’ve ever felt a flicker of fear about the possibility of losing your mind to Alzheimer’s, know this: you are not powerless. You can take action now, and every step you take brings you closer to safeguarding your cognitive future.
