Boost Your Cognitive Power with John Medina’s Brain Rules

Your brain is the most powerful machine you own. But let’s be honest—it’s probably the least cared for. When was the last time you took steps to enhance your cognitive abilities or focused on improving your brain power? If you're like most, the answer is probably never. It’s time to change that.

Enter John Medina, a developmental molecular biologist who knows more about the human brain than most of us could ever hope to. In his book, BRAIN RULES, Medina distills decades of brain sciences into practical advice that will help you optimize your cognitive function. And lucky for you, I’ve boiled it down into the essentials you need to start implementing in your daily lives today.

Get Off Your Butt

This one’s a no-brainer—literally. Physical activity isn’t just good for your body; it’s critical for your cognitive performance. Studies show that regular exercise cuts your risk of Alzheimer’s and dementia in half. But it’s not just about longevity. Aerobic exercise increases oxygen flow throughout your system, flushing out toxins and stimulating the proteins that keep your neurons firing strong.

Back in the day, our ancestors walked an average of 12 miles a day while hunting and gathering. Our bodies evolved for movement, not sitting in front of a computer all day. Regular exercise doesn’t just benefit your physical health; it’s essential for enhancing cognitive abilities. Get moving. Your brain—and your business—will thank you.

Attention

The brain’s ability to focus is crucial to learning, but you need to make it worth the brain’s time. Medina points out that emotionally charged events are better remembered. Think about it—what sticks with you more: a boring meeting or a highly emotional moment in your everyday life? The latter stands out because it triggers an emotional response.

To keep someone’s attention span, you need to give them something worth focusing on. Make it relatable, make it emotional, and break it into small, digestible pieces. People tune out after 10 minutes—so use that time wisely.

Repeat to Remember

Want to know how to improve your long-term memory? Repeat, repeat, and repeat again. The human brain can only hold about seven pieces of information for 30 seconds, so if you want to retain something, you’ve got to repeat it. The more you “encode” information with details, the easier it will stick.

For example, if you meet someone named Mark, say his name three times during your conversation. Not only will it help you remember it, but it’s also a technique used by top networkers. Want to remember that new skill or concept you learned? Apply it right away. Repetition and immediate application strengthen memory formation.

Sleep Well, Think Well

Your brain is far from “off” when you’re sleeping—it’s actually working harder than when you’re awake. Sleep is essential for consolidating memories, improving problem-solving skills, and sharpening creativity. Without it, your attention span, memory, and cognitive abilities all suffer.

Research shows that going 21 hours without sleep is equivalent to being legally drunk. If you want to perform at your best, you’ve got to prioritize sleep. Don’t skimp on it, and if you need a power nap—take it. Even NASA pilots saw a 34% improvement in cognitive function after a 26-minute nap. Your brain needs that recovery time, too.

Stress Kills Brain Function

Short bursts of stress—like facing off with a saber-toothed tiger—are natural and even helpful. But long-term, chronic stress? It’ll shrink your brain, damage your memory, and negatively affect your health. Chronic stress also interferes with sleep and makes you more prone to depression and illness.

If you want to perform well, you need to minimize bad stress. Your cognitive performance and overall health will work best when they’re in a calm, controlled environment. Cut the toxic stressors and focus on managing your workload and personal life effectively.

Stimulate Multiple Senses at Once

The more senses you engage, the better your brain will remember. When you meet someone new, you’re not just hearing their name—you’re seeing their face, hearing their voice, and maybe even feeling their handshake. This multi-sensory input helps your brain create a more complete memory of the experience.

So when you’re learning something new or trying to remember an important concept, use multiple senses to encode that information. The more ways you engage with it, the stronger your recall will be.

Vision Trumps All Other Senses

Your brain is wired to remember visuals. You’re far more likely to remember a picture or a visual scene than a piece of text. If you combine visuals with information, your brain will remember it 65% better. That’s why a picture is truly worth a thousand words.

So when you’re learning or teaching something important, make sure to use visuals. Don’t just read a report—turn it into an infographic or a visual presentation. Your cognitive function will thank you for it.
