A 40-year study of thousands of adults found that people who stayed active in midlife and later life had up to a 45% lower risk of developing dementia.<\/p>\n<p>The <a data-analytics-id=\"inline-link\" href=\"https:\/\/jamanetwork.com\/journals\/jamanetworkopen\/fullarticle\/2841638\" target=\"_blank\" data-url=\"https:\/\/jamanetwork.com\/journals\/jamanetworkopen\/fullarticle\/2841638\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\" data-mrf-recirculation=\"inline-link\" rel=\"nofollow noopener\">study<\/a> used a self-reported physical activity index to measure how much time people spent in slight, moderate, or heavy activity. While the research didn&#8217;t find one intensity to be the single most effective, being regularly active at any level in your 40s and 50s was linked to better brain health later on.<\/p>\n<p><a id=\"elk-seasonal\" data-url=\"\" href=\"\" target=\"_blank\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\"\/><\/p>\n<p id=\"3fc7b1b9-1e01-419f-9c8f-f2a4b1963b9d-2\" class=\"paywall\" aria-hidden=\"true\">That could mean regularly taking the stairs instead of the lift, a quick lunchtime walk, or a few sets with a pair of the <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.tomsguide.com\/wellness\/fitness\/best-adjustable-dumbbells\" data-mrf-recirculation=\"inline-link\" data-before-rewrite-redirect=\"https:\/\/www.tomsguide.com\/best-picks\/best-adjustable-dumbbells\" data-before-rewrite-localise=\"https:\/\/www.tomsguide.com\/wellness\/fitness\/best-adjustable-dumbbells\" rel=\"nofollow noopener\" target=\"_blank\">best adjustable dumbbells<\/a> at home.

During the follow-up, 567 participants were diagnosed with dementia, helping researchers understand how activity at different ages can support brain health over time.<\/p>\n<p>The clearest benefits were seen in midlife and later life. People who were most active in midlife had a 41% lower risk of dementia, and those who remained active in later life had a 45% lower risk. The findings suggest that moving more in your 40s, 50s and beyond can really help keep your memory and thinking sharp.<\/p>\n<p class=\"vanilla-image-block\" style=\"padding-top:56.25%;\">\n<p><img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/11\/zidawrem8BoeAy9hYtxAzk.jpg\" alt=\"a senior woman on an exercise mat\"   loading=\"lazy\" data-new-v2-image=\"true\" data-original-mos=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/11\/zidawrem8BoeAy9hYtxAzk.jpg\" data-pin-media=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/11\/zidawrem8BoeAy9hYtxAzk.jpg\"\/>\n<\/p>\n<p>(Image credit: Shutterstock)<\/p>\n<p id=\"f9c2663c-efd8-4b2b-89e3-85665befeb70\">Exercise in early adulthood didn&#8217;t show a clear link to dementia risk in this study. That doesn&#8217;t mean being active when you are younger isn&#8217;t worth your time. Staying fit early on still boosts heart health, mood and energy. But the good news is that it is never too late to start.<\/p>\n<p><a id=\"elk-what-kind-of-exercise-counts\" class=\"paywall\" aria-hidden=\"true\" data-url=\"\" href=\"\" target=\"_blank\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\"\/>What kind of exercise counts?<\/p>\n<p id=\"17e805e6-6f7b-44d9-a3b3-22a0ef4ffe1d\">You don\u2019t need to be a gym regular to give your brain a boost. Any activity that raises your heart rate a little and challenges your muscles can help, and making a habit of it is key.<\/p>\n<p class=\"newsletter-form__strapline\">Get instant access to breaking news, the hottest reviews, great deals and helpful tips.<\/p>\n<p>That could be a brisk walk around your local park, a few laps in the pool, getting out and about on one of the <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.tomsguide.com\/best-picks\/best-electric-bikes\" data-mrf-recirculation=\"inline-link\" data-before-rewrite-localise=\"https:\/\/www.tomsguide.com\/best-picks\/best-electric-bikes\" rel=\"nofollow noopener\" target=\"_blank\">best electric bikes<\/a>, or even following an online exercise class at home.
