Famed brain scientist Dr. Suzuki said your brain is constantly responding to how you interact with the world. The more diverse and complicated your interactions, the more neural connections your brain will likely make. The less enriched your environment and experience, the fewer neural connections your brain is likely to make.

Did you know that you can grow your brain size and become healthier, sharper and happier by doing it? The key is to use all the various parts and functions of your brain. You do this by doing things you have not done before. New brain stimulating things grow new brain connections. Doing the same things over and over actually causes your brain to slow down and become sluggish and smaller.

According to Suzuki, here are 5 short brain hacks you can do to help enrich your brain, most of which take less than four minutes a day.

Motor Cortex Brain Hack

Go to YouTube and watch a video to learn a new physical skill. Learn a new dance move, the perfect golf swing, juggling – anything that strikes your fancy. And then practice.

Taste Cortex Brain Hack

Try going out for (or better yet, preparing) a cuisine you’ve never had. Korean, Laotian, Ethiopian – you name it. Take your taste buds (and taste cortex) on a cultural adventure. Or for added fun, try eating a meal in complete darkness and see how the lack of visual input affects your sense of taste. You might be surprised.

Visual Cortex Brain Hack

Go to a local museum, pick a piece of artwork you’ve never seen before, and just sit quietly in front of it and let yourself get lost in it.

Auditory Cortex Brain Hack

Go to your preferred music streaming service and search for music from a genre that’s unfamiliar to you. As you listen, reflect. What do you notice about the music? Do you like it and want to learn more, or do you dislike it—why? Does the music bring back any memories for you?

Olfactory Cortex Brain Hack

Take a few minutes to sit and take in the smell of a meal before you eat it. If you have eggs and toast for breakfast, just let their smells waft into your nose before you eat. Breathe in the steam of your coffee before you drink. Learn to appreciate and describe the different smells of your food, and you might learn to appreciate them even more.

To Recap, if you want to give your brain the best chance to continue growing and forming new connections, you need to find ways to continually enrich your world. Simply stay active, meet new people, try new things, and always keep learning.
