Aging: As little as 5 minutes of exercise may keep the brain healthy

Our brains go through some changes as we age. They lose some volume, becoming smaller, which can lead to cognitive issues, such as problems remembering things.

As we get older, the outer layer of the brain — called the cortexTrusted Source — becomes thinnerTrusted Source, and the brain typically starts producing lower levels of neurotransmitters, such as dopamine, which can all contribute to cognitive declineTrusted Source.

Past studies show there are a number of ways in which people can help retain brain health as they age, including following a healthy dietTrusted Source, getting enough quality sleep, quitting smoking, getting enough mental stimulation through activities like puzzles and reading, and being physically activeTrusted Source.

“Age and disease-related declines in cognitive function have far-reaching personal and public health impacts,” Audrey M. Collins, PhD, a postdoctoral researcher in the Department of Neuroscience at the AdventHealth Research Institute in Florida, told Medical News Today.
