How to boost brain power? Well, use your ‘other’ hand

When you step out of your comfort zone and challenge your brain with unfamiliar tasks, it sparks new neural connections. Over time, this may contribute to better memory, creativity, and even delay age-related cognitive decline.

Using your non-dominant hand may make you feel clumsy initially, but it is proof that your brain is working harder.

Synopsys: Using the non-dominant hand can help strengthen the brain, improve flexibility, and build long-term resilience. Switching hands forces the brain to adapt, stimulating regions that are usually less active.

What if improving your brain health is as simple as switching hands while brushing your teeth?

Neurologist Dr Sudhir Kumar of the Apollo Hospitals in Hyderabad has suggested a simple yet powerful trick: Start using your non-dominant hand—the one you don’t usually rely on for everyday tasks.

This small shift can help strengthen the brain, improve flexibility, and build long-term resilience. “Just like muscles, your brain gets stronger with exercise. Switching hands forces your brain to adapt, stimulating regions that are usually less active,” Dr Kumar explained in a recent X post.

Rooted in neuroscience

The idea is rooted in neuroscience: when you step out of your comfort zone and challenge your brain with unfamiliar tasks, it sparks new neural connections. Over time, this may contribute to better memory, creativity, and even delay age-related cognitive decline.

So how do you begin? Dr Sudhir recommends trying a few simple swaps:

Eat or cook with your non-dominant hand
Operate your phone using your non-dominant hand
Write a short note
Brush your teeth, comb your hair, or shave
Practice drumming or piano with your weaker hand leading

“It may feel clumsy at first, but that awkwardness is proof your brain is working harder. And the payoff could be significant. Small changes can add up to better brain resilience over the years,” Dr Kumar noted.

Simple exercises

Meanwhile, experts suggested a few more simple, science-backed brain-strengthening exercises that could be helpful. For instance:

Learn a new language, which can help in activating memory and problem-solving skills.
Play a musical instrument, which could improve coordination, memory, and creativity
Solve puzzles like crosswords, sudoku, etc
To challenge spatial awareness, take a different route to work/home
Read aloud as it strengthens comprehension and recall
Meditation improves focus.

The next time you pick up your toothbrush or unlock your phone, consider giving your other hand a chance—it could be the simplest brain workout you’ll ever try.
