Take Up Cycling as a Hobby. It Might Literally Save Your Brain.

June 16, 2025

A gigantic study of nearly half a million people living in the UK, published in JAMA Network Open, by researchers from Huazhong University of Science and Technology and the University of Sydney found that riding a bike might be doing a lot more than making your legs look shredded. It could be protecting your brain’s memory centers from shrinking.

The researchers suggest it’s not just the pedaling that helps. Navigating traffic, choosing routes, staying alert, and simply moving your body all demand brainpower that keeps your brain sharp and focused. These factors might be exercising the brain just as much as the body. Add fresh air and social exposure, and you’ve got a cognitive workout. Vice
