There's a simple way to sharpen your thinking and improve your memory

Research shows that regular physical activity improves three key areas of brain function.

Many of us turn to Sudoku, Wordle or brain-training apps to sharpen our minds. But research is increasingly showing that one of the best ways to boost memory, focus and brain health is exercise.

Our new research reviewed data from more than 250,000 participants across 2,700 studies. We found that exercise helps boost brain function — whether it's walking, cycling, yoga, dancing or even playing active video games like Pokemon GO. Moving your body improves how we think, make decisions, remember things and stay focused — no matter your age.

WHAT THE SCIENCE SAYS

Our review adds to a growing body of research that shows regular physical activity improves three key areas of brain function.

We conducted an umbrella review, which means we looked at the results of more than 130 high-quality research reviews that had already combined findings from many exercise studies. These studies usually involved people starting a new, structured exercise programme, not just tracking the exercise they were already doing.

To assess the effects on cognition, memory and executive function, the original studies used a range of brain function tests. These included things like remembering word lists, solving puzzles or quickly switching between tasks — simple activities designed to reliably measure how well the brain is working.
