How to Keep Your Brain Smarter Than a Fifth Grader

Boost Your Brain Health: How Neuroplasticity and Exercise Keep You Sharp

The brain is a powerhouse that constantly changes and forms new neural connections as we learn. This ability, known as neuroplasticity, allows the brain to adapt and reorganize based on experiences throughout life. Whether you suffer an injury or encounter a new experience, your brain will change in response. Keeping your brain healthy ensures peak performance, so you’ll always stay smarter than a fifth grader. But what can you do to maintain your brain health?

What Impacts Brain Health?

Physical exercise plays a significant role in improving brain health. It increases blood flow to the brain, reducing inflammation. Exercise also stimulates endorphin production, natural painkillers and mood boosters, while lowering cortisol levels (the stress hormone). With more endorphins and less stress, you can boost your mood and overall brain function.

Beyond mood improvement, exercise brings physical changes to the brain, such as a thicker cerebral cortex and better white matter integrity. Increased blood flow also brings more oxygen and nutrients to the brain, supporting neuronal function. Regular exercise triggers neuroplasticity, improving your ability to learn and adapt to new information.

Scientific Evidence Supporting Exercise for Brain Health

A 20-year study of 454 adults found that consistent physical activity was linked to better memory and cognitive function. Those who exercised regularly had a 31% lower risk of developing dementia. Another study showed that even participants who did not meet physical activity guidelines saw benefits. Just 7,500 steps a day, or an hour of light exercise, was associated with a higher brain volume equivalent to 1.4-2.2 years of less brain aging.

Start Exercising for a Smarter, Healthier Brain

Exercise is an easy and effective way to keep your brain young, fit, and sharp. Anyone, at any age, can start incorporating more physical activity into their day. It improves not just your brain but your mood, body, and overall health. Along with physical activity, engage in intellectually stimulating activities like puzzles, vocabulary games, and learning new languages to keep your brain sharp. With these habits, you’ll stay smarter than a fifth grader for years to come!

At 12, he began volunteering in various capacities, including preparing food, cleaning trash, assisting with after-school activities, and more. However, it wasn’t until he took his first actual science course in high school at age 14 that he developed a passion for science.

Combining his love for helping others with his interest in science, Jang attended the University of California, Davis, and earned a Bachelor of Science in Neurobiology, Physiology, and Behavior (NPB). His time there cemented his passion for healthcare. Since graduating, he has worked at various clinics, hoping to gain as much knowledge and experience as possible to positively impact people’s lives.

Initially, Jang aspired to become a Physician Assistant. After working at Norcal Brain Center for a year and witnessing its profound impact on patients, he hopes to become a clinical neurologist one day.

He enjoys working out, spending time outdoors, and exploring new restaurants with friends and family in his free time.
