Well, here I go again talking about the benefits of regular exercise! Now, to be clear, I’m not exactly “buff,” not even close. But I do make it a priority to stay active, whether that means a brisk walk, some lightweight training, or following along with a YouTube workout. The key is consistency, and science backs it up.

A study published in Brain Communications found that lifelong physical activity may help protect against cognitive decline, even in individuals with key markers of Alzheimer’s disease. Researchers tracked how often people engaged in activities like walking, swimming, and even team sports over the course of three decades before and after turning 50. The results were clear—those who exercised at least once a month before age 50 had less shrinkage in the hippocampus, the part of the brain responsible for learning and memory.

David Thomas, head of policy and public affairs at Alzheimer’s Research UK, emphasizes that dementia is not an inevitable part of aging. Preventing cognitive decline is possible, and regular exercise plays a crucial role in that effort.

At the end of the day, it’s never too early—or too late—to make positive lifestyle changes. Staying active, engaging in mentally stimulating activities, and maintaining social connections can all contribute to healthier, happier years ahead. So why not take a walk? Invite a resident or two, step outside, enjoy the sunshine, and move together. What’s the downside?

Stay well and stay informed!
