Huh? This is why you should brush your teeth with your non-dominant hand

Neuroplasticity

Your brain is amazingly flexible. We call this adaptability neuroplasticity. Throughout your life, your brain continues to adapt and develop based on your experiences. New connections are formed, while old ones disappear when they are no longer needed. This process is essential for learning, remembering and even recovering after damage.

As we age, the neuroplasticity of our brain decreases. Older brains make fewer new connections and fall back on familiar paths faster. But here comes the good news: you can train your brain to stay flexible, and it doesn't have to be complicated at all.

The power of brushing your teeth with your other hand

A simple way to train your brain is to brush teeth with your non-dominant hand. Are you right-handed? Try it with your left. Left-handed? Grab that toothbrush with the right. Researchers have found that this small change helps form new connections in your brain. Your brain is stimulated to step out of its routine and this keeps you mentally sharp.

Why this works so well? It has to do with the cooperation between the left and right hemispheres of your brain. Your left hemisphere controls your right hand, and vice versa. By brushing with your non-dominant hand, you strengthen the interaction between both hemispheres of the brain. This is not only good for your memory and concentration, but also contributes to your overall mental health.

Breaking routine: good for your brain

Our brain likes routines because they save energy. But routines can also make your brain a bit lazy. Making small changes to your daily habits will keep your brain sharp and flexible. Brushing your teeth with your other hand is a low-key way to do that, but there are many other ways to challenge your brain:

• Eat with your non-dominant hand. It feels awkward, but it stimulates the same brain areas.
• Try writing with your other hand. This is challenging, but fun to practise.
• Take a different route to work. Even small changes in your daily environment stimulate your brain.

A mental workout without extra effort

The beauty of this exercise is that you don't have to set aside any extra time for it. You just integrate it into your existing routine. The result? A fitter brain that is better able to learn new things and let go of old habits.

So, grab that toothbrush and switch hands. Who knows, maybe it will inspire you to take a closer look at other daily habits too. Your brain will thank you!
