Light exercise can yield significant cognitive benefits, new research shows
Everyday physical activity significantly enhances cognitive health, reversing four years of cognitive aging, according to a Penn State study highlighting movement’s importance of exercise for mental benefits.
Exercise
Everyday physical activity, like going for a short walk or playing with the kids, may provide short-term benefits for cognitive health, equivalent to reversing four years of cognitive aging. That was a key finding for my colleagues and me in our new study, which was published in the journal Annals of Behavioral Medicine.
Prior to enrollment into a study of diet and dementia risk, we asked a diverse sample of 204 middle-aged adults to check in five times per day for a period of nine days, via a smartphone application.
Each check-in involved completing a brief survey that asked about their mood, dietary choices and whether they engaged in any physical activity in the roughly three and a half hours leading up to the survey. In addition, participants completed a few brief brain games – meaning performance-based cognitive assessments that lasted about one minute each – to assess mental speed and short-term memory.
My team found that performance on our measure of cognitive processing speed improved during check-ins when participants reported being physically active in the time leading up to the survey. While we didn’t see improvements in our measure of working memory, the time taken to complete the memory task mirrored what we saw for the measure of processing speed.
We observed these improvements in speed regardless of whether the activity was lighter intensity or moderate-to-vigorous intensity. This led us to conclude that movement, whether it took the form of intentional exercise or part of a daily routine, was the essential ingredient for achieving this benefit.
Why it matters
As a rule, we get slower, both physically and mentally, as we age. While research on exercise and living a healthy lifestyle has demonstrated the long-term cognitive and brain health benefits of remaining physically active, much of this work has focused on the moderate- to vigorous-intensity physical activity – or what most of us think of as exercise – recommended by the Physical Activity Guidelines for Americans.
Still, these guidelines and other experts recommend that adults move more and sit less.
My colleagues and I are interested in understanding how moving more can improve our cognitive health or reduce our risk of dementia as we age, at what timescale these benefits show up, and what types of movement qualify. https://www.youtube.com/embed/lk3mrNqhn24?wmode=transparent&start=0 Exercise promotes blood circulation and the growth of neurons.
What still isn’t known
Our study relied on participants to report whether they had been physically active during the time between each check-in. Even though participants were provided training on how to think about the intensity levels, it’s possible that each participant had a slightly different perception of their activities.
For example, a participant may not have believed their recent walk actually qualified as a moderate-intensity activity. Physical activity monitors that can dissociate time and intensity might help future research unravel these associations more clearly.
What’s next
It isn’t yet clear whether these short-term benefits accumulate over time to result in long-term improvements in brain health and dementia risk reduction. Research efforts are underway by our team to better understand these associations over broader timescales.
My research involves data collection via smartphones and wearable devices to help us better understand how health-promoting behaviors and cognitive health interact as we age. This type of digital approach allows my team to pursue questions about how everyday behavior and experience influence cognition in daily life and represents a significant methodological advancement in the dementia risk and prevention research space.
Using these tools, we aim to better identify individuals at risk for negative cognitive outcomes and new targets for dementia prevention.

(Feature Impact) To add charm to your yard, encourage local wildlife and give you a front-row seat to nature, building a birdhouse is a simple weekend project that checks all of those boxes.
Building a Birdhouse
Seasoned DIYers and first-timers alike can follow this step-by-step guide to create a functional, welcoming birdhouse.
Step 1: Choose the Right Design
Start by deciding what type of birds you’d like to attract. Different birds prefer different house sizes and entrance types. A simple, classic birdhouse design makes the project beginner-friendly and works well for common backyard birds like wrens, chickadees and bluebirds. In general, plan for at least a 1-1 2/2-inch entrance hole, a 5-by-5-inch interior space and 2 inches or more of roof overhang.
Step 2: Gather Materials and Tools
Most DIY birdhouses can be built with basic materials and tools you may already have at home, including untreated cedar or pine wood, screws or nails, wood glue, sandpaper and exterior-safe paint as well as a measuring tape, pencil, saw and drill.
Step 3: Measure and Cut Wood
Measure and cut wood to make the front panel, back panel, two side panels, floor and roof. Then sand all edges for smooth assembly.
Step 4: Drill Holes
Using a hole-saw bit, drill the entrance hole into the front panel. Position it a few inches below the roofline to keep predators out. Next, drill 2-3 small drainage holes in the floor piece to prevent water buildup and help keep the birdhouse dry.
Step 5: Assemble the Birdhouse
Attach the side panels to the back panel using screws or nails. Add the front panel then secure the floor piece, slightly recessed, so rainwater can drain. Attach the roof last, making sure it slopes slightly to allow water to run off.
Step 6: Paint the Exterior
If you plan to paint your birdhouse, stick to neutral, nature-inspired colors. Light browns, soft greens or white help regulate temperature and blend into the environment.
Step 7: Mount Your Birdhouse
Once dry, place your birdhouse in a quiet, sheltered spot away from heavy foot traffic. Mount or hang it 5-10 feet off the ground, facing away from prevailing winds.

Study Links Agent Orange Exposure to Higher Risk of Rare Melanoma
A study revealed that U.S. veterans exposed to Agent Orange are at increased risk of developing acral melanoma, a rare skin cancer located in areas not typically exposed to sunlight. With higher odds of diagnosis and poorer prognosis, early detection in veterans is vital for effective treatment and improved outcomes.
(Feature Impact) A new study found U.S. veterans exposed to Agent Orange face a higher risk of developing a rare and often overlooked form of melanoma that appears on the hands and feet, and under the nails.
Researchers reported in “JAMA Dermatology” that veterans with documented exposure to the herbicide had significantly higher odds of developing acral melanoma, a subtype of skin cancer that forms on the palms, soles and nail beds.
Unlike most melanomas, which are associated with ultraviolet radiation, acral melanoma develops in areas not typically exposed to the sun. It can resemble a bruise under a toenail or a dark patch on the bottom of a foot – locations that are easily missed and not commonly associated with skin cancer.
Because of its unusual appearance and location, acral melanoma is often diagnosed at later stages, when treatment is more difficult and survival rates are lower.
The researchers analyzed 20 years of Veterans Health Administration data, comparing more than 1,200 veterans diagnosed with acral melanoma with more than 5,000 veterans without melanoma. Veterans exposed to Agent Orange had about 30% higher odds of developing the disease.
The findings suggest Agent Orange may be an underrecognized risk factor for acral melanoma, particularly for veterans who may not view themselves as at risk for skin cancer because of limited sun exposure or darker skin tones.
“Identifying exposures that may increase risk can help inform earlier recognition and, ultimately, earlier diagnosis when treatment is most effective,” said Marc Hurlbert, chief executive officer of the Melanoma Research Alliance and a principal investigator on the study.
Senior author Dr. Rebecca I. Hartman of Brigham and Women’s Hospital said acral melanoma behaves differently from other melanomas and often responds less well to current therapies.
“Acral melanoma has a poorer prognosis than the more common cutaneous melanoma because it is often diagnosed at later stages,” Hartman said. “Identifying risk factors is critical to improving detection and outcomes.”
Agent Orange was used extensively during the Vietnam War and exposure has been linked to several cancers and chronic illnesses. These findings add to evidence the herbicide may also affect the skin in ways not reflected in traditional melanoma awareness efforts.
Acral melanoma has also been associated with sex, race and ethnicity, and prior skin lesions. Researchers said the study supports treating the disease as distinct from sun-driven melanomas that dominate public education campaigns.
For veterans, the research highlights the importance of examining less visible areas of the body, including the bottoms of the feet, between the toes and under the nails. Changes in nail color, dark streaks or unexplained spots on the palms or soles should be evaluated by a health care provider, especially for those with known Agent Orange exposure.
Researchers said the findings could help guide future screening strategies for higher-risk populations and encourage further study of why acral melanoma differs biologically from other skin cancers.

Progress, Not Perfection: How Healthy Habits Can Stack Up One Step at a Time
The article emphasizes that achieving better health relies on progress, not perfection. It advocates for realistic goals and highlights tools like My Life Check for personalized health assessments. Small, manageable changes in diet, exercise, sleep, and stress management can significantly impact overall well-being, making healthy habits more attainable and sustainable.
Progress, Not Perfection: How Healthy Habits Can Stack Up One Step at a Time
(Feature Impact) Despite the best of intentions, it’s common for plans to build healthier habits to fall flat. Often, the culprit isn’t a lack of motivation or discipline; rather, it’s unrealistic expectations.
Overhauling your lifestyle requires a level of commitment that isn’t always practical. Understanding your personal health needs and the challenges you need to overcome can help give you a more realistic roadmap toward better health.
Tools to Guide You
Every plan needs a starting point and there are many reputable sources that can help guide you toward a plan that addresses your personal health needs.
For example, the American Heart Association introduced My Life Check, a simple, free tool to help individuals understand their heart health and what’s driving it. Users answer simple questions about their daily habits and health factors to get a personalized Heart Health Score in minutes.
The results are private and downloadable, giving you full control of your information. The tool turns big goals into small, specific actions you can start right away. Knowing your numbers relative to your heart health (and where you are in comparison to target ranges for optimal health) can help you decide how to build a better map to get you where you want to be.
While the report is customized to each individual, no personal data is stored and answers are only used to calculate health scores and provide personalized recommendations and practical steps to improve your health, so you can use your results to focus on what matters most to you. Every small step you take, such as moving more, eating smarter, sleeping better or managing stress, can add up over time.
Finding Your Path
Once you’re armed with data and know where you stand on your heart health numbers, small steps become clearer and more manageable. That knowledge makes it easier to choose one area to focus on, such as getting more sleep, taking daily walks or adding more color to your meals.
Healthy changes don’t need to be expensive or complicated. The best habits are ones that fit real life when every action you take moves you closer to your goals.
Staying motivated and on track is also easier when you can check back in, see your progress and realize the steps you’re taking are making an impact. Checking in every few months to see how you can grow gives you the chance to celebrate your progress, learn from challenges and keep building lasting habits that feel good.

Healthy Habits for Everyday Life
Eat Smart
Choose foods that help you feel your best, one meal at a time. Add more color to your plate and focus on balance, not restriction. Simple, affordable swaps can make a real difference.
Smart Tip: Aim for an overall healthy eating pattern that includes whole foods, fruits and vegetables, lean protein, nuts, seeds and cooking in non-tropical oils such as olive and canola.
Move More
Find movement that fits your life, such as a walk, a stretch or dancing while you cook. Every bit of activity counts and it all supports your heart and mind. Move for joy, not just for results.
Smart Tip:Adults should get 150 minutes of moderate physical activity (or 75 minutes of vigorous activity) per week. Kids should aim for 60 minutes every day, including play and structured activities.
Sleep Well
Rest is a foundation of good health, not a reward. Protect your bedtime routine and give your body the recovery it deserves. Notice how good sleep makes everything else easier.
Smart Tip: Most adults need 7-9 hours of sleep each night. Children require more. Adequate sleep promotes healing, improves brain function and reduces the risk for chronic diseases.
Manage Stress
Check in with yourself regularly, both mentally and emotionally. Create simple moments to pause, breathe, laugh or step outside. Connection, kindness and calm all support a healthy heart.
Smart Tip:The first step to stress management is awareness. Step “away from yourself” for a moment. Objectively ask yourself, “Is my stress level too high?” If so, look at what might be causing that stress.
Ideas for Incremental Changes
- Dedicate 15 minutes at the beginning or end of the day to focus on self-care, whether it’s unwinding with some music, writing down your goals or reflecting on the highlights of the day.
- Aim to add an extra serving of fruits or veggies each day, such as creating a savory veggie omelet or exploring new smoothie blends that let you pack in the produce on the go.
- Give your cabinets a quick update and put the smaller plates front and center. When you use a smaller plate, you can fill it while still sticking to recommended serving sizes.
- If you’re not a fan of the gym, think about how your hobbies can play a role in your physical activity. Even gardening counts as physical activity, so get creative to get moving with an activity you truly enjoy.
- Establish a bedtime routine that allows you to ease into sleep more easily. Once you feel the impact of better-quality rest, you may find yourself more motivated to make a regular bedtime a priority.
