Is the Brain a Muscle? How Mental Exercise Strengthens Your Thinking Skills

How Muscles and Brains Share Some Key Traits

There are certainly some important ways in which our muscles and brains overlap:

They Can Be Strengthened Through Use

Just as muscles grow stronger through physical exercise, the brain can become more powerful through mental exercise. Activities that challenge the brain - like puzzles, strategic games, learning a language or playing a musical instrument - help build neural connections and "strengthen" the brain over time.

Use It or Lose It Applies to Both

If muscles aren't exercised consistently, they begin to weaken and atrophy over time. The same goes for the brain. Regular brain training helps keeps our cognitive abilities sharp. But without mental stimulation, we begin losing mental acuity as we age.

Mental and Physical Exercise Promote Growth

Exercise causes muscles to release proteins that promote tissue growth. The brain also releases growth-promoting proteins when challenged. Mental exercise stimulates neuron growth and connectivity in the brain, allowing it to expand its capabilities.

They Require Rest to Recharge

While working out is essential, rest days are also important for muscles to recover and repair themselves. The brain similarly needs down time to consolidate everything it has recently learned. Getting adequate sleep is crucial for brain health.

The Differences Between Muscles and Brains

Though they share some basic traits, there are also many important differences between muscles and the brain:

Muscles Have Limited Functions, Brains Control Everything

While muscles play specific mechanical roles in the body, the brain controls every possible bodily process from breathing to movement to emotions. The brain's scope is unlimited compared to any single muscle.

Brains Cannot Be Directly Controlled, Muscles Can

We can consciously control our muscle movements, contracting them on command. But we do not have this same level of control over our brain activity or thinking. The brain controls itself based on external stimuli.

Muscles Rely on the Brain, Not Vice Versa

The brain sends electrical signals through the nervous system to tell muscles when to contract. Without these signals, muscles cannot function. The brain does not require any direction from muscles in order to perform its roles.

Muscle Growth Has Limits, Brain Growth Potentially Unlimited

There is only so much muscles can grow within the confines of our body size and genetics. But because the brain is not limited physically, its ability to continue making new connections and expanding memory storage capability is essentially limitless.

Muscles Decline with Age, Brains Can Continue Improving

Physical muscle performance typically peaks around age 30 before declining. But brains can continue enhancing cognitive skills and adding knowledge indefinitely in life as long as they are exercised properly.

How to Exercise Your Brain Effectively

Now that we understand the similarities and differences between muscles and the brain, let's discuss how to "exercise" your brain optimally so it stays vigorous and adaptable throughout life.

Vary Your Mental Activities

Just like varying your muscle workout routine produces better overall fitness, engaging in diverse brain training activities (logic games, new skills, puzzles, reading, socializing) exercises your brain more comprehensively.

Challenge Yourself

Try brain training activities that are outside your comfort zone and push your mental abilities. As skills become easy, increase difficulty to spur new brain cell growth.

Break Mental Routines

Mix up your daily mental habits and behaviors to activate different neural pathways. Don't run your brain on autopilot.

Stay Mentally and Socially Active

Isolating yourself puts your brain at a disadvantage. Interacting with others and staying engaged with the world provides cognitive stimulation.

Practice Mind-Body Exercises Like Yoga

Activities integrating physical and mental skill, breath control and mindfulness such as yoga powerfully enhance brain connectivity and performance.

Get Enough Sleep

Skimping on sleep hampers memory consolidation and thinking abilities. Strive for 7-8 hours per night.

Eat a Brain-Boosting Diet

Provide your brain the nourishment it needs by eating foods rich in nutrients like B vitamins, antioxidants and healthy fats.

Brain-Strengthening Exercises and Activities

There are endless options for keeping your brain young and fit. Here are 10 great brain exercise examples you can start doing today:

1. Switch Up Your Commute

Drive or walk a different way, identify new objects along the path and work your spatial orientation and mapping skills.

2. Learn a Language

Mastering a new language develops memory capability, mental flexibility and sharpness.

3. Take a Class

Enrolling in an academic course challenges the brain with new concepts and boosts learning ability.

4. Play Strategy Games

Games like chess, checkers and Go require forethought, focus and problem-solving skills.

5. Practice Memorization

Perform memory training exercises like memorizing lists, recipes or speeches to build mental retention.

6. Do Puzzles and Riddles

Crosswords, Sudoku, jigsaw puzzles and brain teasers flex mental power and acuity.

7. Study a New Skill

Learning to cook, paint or play an instrument boxes your brain think and absorb new information.

8. Play Improvisational Games

Making up songs, dances or fictional stories on the fly sparks creative neural connections.

9. Prioritize Quality Sleep

Without solid rest, the brain lacks the down time required to process new memories and learning.

10. Socialize Regularly

Meaningful social interaction and conversation provides vital cognitive stimulation as we age.

The Takeaway

Treating the brain like a muscle that benefits from training is a useful mental model - with some important caveats. While brain exercises strengthen thinking skills, the brain is far more complex than any single muscle. Providing your brain with diverse stimulation, proper nutrition and rest will help keep it nimble regardless of age. So flex your mental muscles regularly and continue building cognitive capacity across your lifespan.
