When we think about intelligence, we often imagine people with sharp minds, quick thinking, and an ability to recall facts on demand. While these are certainly signs of intelligence, the traits and behaviors that contribute to being “smart” are often far subtler and more surprising.
Research has shown that intelligence isn’t only about genetics, moderate physical activity, or academic achievement; it’s about the habits we cultivate, the activities we engage in, and even the quirky behaviors we exhibit. In fact, there are several unusual things that can actually help make us smarter.
Here are 10 of the most intriguing ways you can boost your brainpower, backed by the latest science.
Sleep Isn’t Just for Resting: It’s for Memory Building
We all know that sleep is essential, but did you know that it plays a critical role in memory consolidation? When we sleep, our brain goes into a processing mode, organizing and storing the information we’ve learned throughout the day.
Studies have shown that sleep strengthens the synapses, the tiny connections between neurons, which helps us retain new knowledge and skills. This is especially true for deep sleep, the phase that helps solidify long-term memories and enhances our ability to solve problems.
So, rather than viewing sleep as a waste of time, we should think of it as a necessary tool for sharpening our minds. In fact, skipping sleep can be detrimental to cognitive performance and problem-solving abilities.
Napping Can Actually Improve Your Learning
While we may associate napping with laziness, research has demonstrated that taking a nap can significantly improve our ability to learn and remember information.
After a good night’s sleep, a brief afternoon nap of around 20-90 minutes has been shown to boost memory recall and improve cognitive function. This is particularly effective for retaining new vocabulary, numbers, and tasks learned earlier in the day.
So, next time you feel your energy dip in the afternoon, remember that a quick nap can help boost both your mood and brainpower.
Physical Activity Fuels Mental Agility
Exercise is one of the simplest yet most effective ways to improve cognitive function. Recent studies have found that activities such as walking, swimming, or cycling have positive effects on the brain’s ability to process information, solve problems, and increase reaction time.
Exercise promotes the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and maintenance of brain cells.
In fact, studies have shown that people who engage in regular physical activity have higher levels of BDNF and, as a result, tend to perform better on cognitive tasks. Just a short walk can increase blood flow to the brain and give your thinking an immediate boost.
A Walk in Nature Helps You Focus
It turns out that spending time outdoors can give your brain the perfect reset. A nature walk has been shown to reduce mental fatigue and improve concentration. Studies have demonstrated that walking among trees or in green spaces can have a restorative effect on cognitive function, especially on
focus, working memory, and decision-making. Urban environments, on the other hand, tend to be filled with distractions and noise that wear down our mental resources. So next time you’re feeling mentally drained, step outside and immerse yourself in nature, your brain will thank you.
Handwriting Can Boost Memory Better Than Typing
In an age where typing has replaced handwriting for many, you might be surprised to learn that writing by hand actually leads to better retention of information.
Research has shown that when we write things out by hand, we engage in deeper cognitive processing, forcing the brain to process the information in more detail. Handwriting has been linked to improved memory retention, reading comprehension, and creative thinking.
So, when it comes to studying, taking notes by hand may not only help you better remember the material but could also increase your creativity and analytical skills in the process.
Drawing Can Improve Memory Retention
You don’t need to be an artist to benefit from drawing. Studies have shown that sketching concepts, diagrams, or even doodling can significantly improve recall and understanding. When we draw something, we are forced to process it both visually and conceptually, which makes the information more memorable.
In fact, one study found that people who drew the words they were trying to memorize performed better on recall tasks than those who simply wrote them down. So, the next time you need to remember something, try drawing it out. It may help solidify the memory better than a simple note.
Curiosity Is More Than a Personality Trait: It’s a Learning Superpower
Curiosity isn’t just about asking questions; it’s about engaging with the world in a way that makes us want to explore and understand. Research has shown that people who are highly curious have stronger memory systems, as their brains are constantly seeking out new information.
A 2024 study confirmed that curiosity-driven learning results in better memory retention and faster processing of new information. This is because when we’re curious, we’re more likely to pay attention, and our brains are more likely to encode that information into long-term memory. So, cultivate your curiosity, ask more questions, and enjoy the rewards of a smarter brain.
Bilingualism Boosts Cognitive Reserve
Being bilingual doesn’t just help you communicate in multiple languages; it also boosts your cognitive reserve, which is your brain’s ability to resist damage and function despite aging or neurodegenerative diseases.
A 2023 study found that bilingual adults exhibited better executive function in tasks like switching between activities, planning, and decision-making, even in older age.
This may be because managing two languages exercises parts of the brain that are responsible for attention and memory. So, whether you’re fluent in another language or just dabbling in one, keep those language skills sharp for long-term brain health.
Music Training Can Sharpen Cognitive Skills
Learning to play a musical instrument is more than just a fun hobby; it’s an excellent way to boost cognitive function. Research has shown that music training enhances memory, attention, and even emotional intelligence.
One study found that people who had trained in music had better working memory and were quicker to perform tasks involving attention. Another study showed that music training could improve the ability to process auditory information. So, if you want to strengthen your brain while enjoying a creative outlet, picking up an instrument could be the perfect option.
Chewing Gum Might Help You Stay Alert
It might sound trivial, but chewing gum has been shown to enhance alertness and focus. Studies suggest that gum-chewing increases blood flow to the brain, enhancing cognitive performance in short bursts.
While it’s not a magic solution for intelligence, it has been found to improve concentration, especially during tasks that require attention and mental agility. If you need to stay focused during a long meeting or a challenging task, popping a piece of gum could be your secret weapon.
