The 12 Brain Rules: Let’s Break Them Down
Now, let’s talk about the 12 brain rules Medina covers in the book. These are the main principles we can use to keep our brains functioning at their best, with some easy-to-implement tips to make them work for you.
1. Exercise: The Brain Loves Movement
The first rule might seem obvious—your brain loves exercise. But here’s the kicker: exercise doesn’t just make you fit, it makes your brain sharper. Studies show that exercise boosts brain function, increases memory, and helps with stress management.
How to Apply This Rule:
Get moving for at least 30 minutes a day. This can be anything from a brisk walk to dancing around your living room.
Try to do something physical right after you’ve learned something new. It’ll help your brain make those neural connections stronger.
2. Sleep: The Brain Needs Sleep to Learn
I know, I know—you’ve heard this one before, but it’s a game-changer. Sleep is essential for brain health and learning. Without enough sleep, your brain can’t store memories properly or process new information.
How to Apply This Rule:
Aim for 7-9 hours of sleep each night. Your brain does some of its best work while you’re snoozing.
Create a bedtime routine that signals to your brain it’s time to wind down (no scrolling on your phone for an hour before bed, okay?).
3. Wiring: Every Brain is Wired Differently
Did you know that each brain is unique? People have different strengths and wiring based on genetics and environment. And that’s something to celebrate, not fix.
How to Apply This Rule:
Embrace your own brain’s quirks—whether you’re better at math, art, or something else. Play to your strengths!
If you’re a parent or teacher, remember that kids have their own ways of learning. Adjust your approach to how they best engage.
4. Attention: The Brain Can Only Focus on One Thing at a Time
We think we’re multitasking, but nope, the brain doesn’t actually work that way. Trying to juggle multiple tasks can hurt your focus and productivity.
How to Apply This Rule:
Single-task when possible. Focus on one thing at a time to really give it your full attention.
If you find yourself getting distracted, try the Pomodoro technique—work for 25 minutes, then take a 5-minute break. It helps you stay sharp and productive.
5. Short-Term Memory: We Can Only Keep 7 Things in Mind at Once
Did you know your brain can only hold 5-9 pieces of information in your short-term memory at any given moment? If you're trying to remember 10 things at once, you're setting yourself up for failure.
How to Apply This Rule:
Chunk information into groups to make it easier to remember. For example, if you’re trying to remember a phone number, group the digits into chunks.
Write things down to get them out of your brain and onto paper (or your phone). It’ll free up some space for new ideas.
6. Memory: Repetition Makes It Stick
When you repeat something over and over, your brain turns it into a long-term memory. It’s like practicing a sport or playing an instrument—the more you do it, the better you get.
How to Apply This Rule:
Practice makes perfect, right? Review and repeat important information (like notes for a test or a presentation) regularly.
Use spaced repetition—study something today, then again in a few days, and a week later. It’s a great way to improve long-term retention.
7. Sensory Integration: We Learn Best With All Our Senses
We tend to think learning is all about reading and listening, but in reality, our brains are much more powerful when we use multiple senses. The more senses involved, the more likely we are to remember something.
How to Apply This Rule:
When you’re learning something new, try to engage as many senses as possible. Read, write, say it out loud, and even act it out if you can!
Experiment with learning styles—visual, auditory, kinesthetic—until you find what works best for you.
8. Stress: Stress Changes the Way the Brain Works
Stress gets a bad rap (for good reason). When you’re stressed, your brain’s ability to think, learn, and retain information goes down. In fact, chronic stress can shrink brain areas involved in memory and learning!
How to Apply This Rule:
Manage stress with techniques like deep breathing, yoga, or mindfulness.
Take breaks when you’re feeling overwhelmed. Don’t push yourself to keep going when you’re stressed—it’ll hurt your brain in the long run.
9. Vision: Vision Trumps All Other Senses
Our brains rely heavily on vision—in fact, it’s our dominant sense. If you’re trying to remember something or learn something new, using visuals can help tremendously.
How to Apply This Rule:
Use visuals in your learning process. Charts, graphs, and even just writing things down can help you retain more.
If you’re trying to solve a problem, sketch it out or use mind maps. It’ll make the concept clearer and easier to remember.
10. Gender: Men and Women Are Different
While we’re all human, Medina explains that men and women’s brains do have some biological differences. For example, men may be better at navigating space, while women tend to have better verbal skills. It’s important to acknowledge these differences but not to use them as a limiting factor.
How to Apply This Rule:
Embrace your natural strengths and don’t feel pressured to conform to stereotypes.
If you’re working with others, be aware of gender differences in communication and learning styles. It’ll help create a more collaborative, effective environment.
11. Exploration: The Brain Thrives on Exploration
Curiosity might have killed the cat, but it feeds the brain. Medina emphasizes that our brains are wired to explore, ask questions, and try new things. Exploration is how we learn and grow.
How to Apply This Rule:
Be curious about the world around you. Ask questions, explore new hobbies, and take on new challenges.
Try new things—whether it’s a new workout routine or reading a book outside your normal genre. Keep your brain engaged!
12. Sleep: Sleep and Memory Go Hand in Hand
We’ve already touched on the importance of sleep, but this rule stresses that good sleep is the foundation of a healthy brain. Without it, everything from memory to decision-making suffers.
How to Apply This Rule:
Prioritize good sleep hygiene—keep a regular sleep schedule, create a peaceful sleep environment, and turn off screens at least an hour before bed.
What’s the Takeaway?
Brain Rules isn’t just a book about the brain; it’s about how you can apply the science of your brain to live better. From improving sleep to managing stress and exercising more, there are so many ways you can optimize your brain health based on Medina’s principles.
So, if you’re feeling like you’re not operating at your brain’s best, start by experimenting with a couple of these rules. Trust me, your brain will thank you! The coolest part is that you’re not just learning “facts” about your brain—you’re learning how to take care of it. And that, my friend, can make all the difference in how you think, feel, and perform.
