While gym workouts often get all the glory, a new study from Penn State suggests that sweating it out isn’t the only path to a healthy mind. Simple, everyday movements – like folding laundry, cooking, or walking the dog – can significantly boost brain health. Researchers found that these small bursts of activity improve processing speed, making the brain function as if it were four years younger.
Everyday chores and walking boost brain speed
We often overlook the physical effort of daily life. Scientists call this incidental physical activity. It includes all the movement you do that is not planned exercise.
The Penn State study findings
A team from Penn State College of Medicine decided to track how these small movements affect the brain in real time. They used a method called ecological momentary assessment. This means they did not just ask people to remember their week. Instead, participants used smartphones to report their activity and take quick brain tests several times a day.
The results published in the Annals of Behavioral Medicine were clear. When people had been active in the few hours before a test, their brains worked faster. Specifically, their processing speed – how quickly the brain takes in and uses information – improved. The researchers calculated that this boost was equivalent to the difference in processing speed between people four years apart in age.
Light activity vs vigorous exercise
The study found that you do not need to run or lift heavy weights to get this specific mental benefit. Light-intensity physical activity was enough to trigger the effect.
- Light activity: Walking slowly, dusting, cooking, or gardening.
- Vigorous activity: Running, fast cycling, or heavy lifting.
While vigorous exercise is excellent for the heart and muscles, this research shows that the brain rewards even gentle movement. This is good news for people who may find gym workouts difficult or intimidating.
How simple movement affects cognitive health
The benefits of movement appear to be immediate but also cumulative. The study showed that people who moved more often generally had higher baseline cognitive scores.
Processing speed vs working memory
The researchers noted a specific improvement in processing speed. This is the mental engine that helps us react to the world, follow conversations, and complete tasks quickly.
Interestingly, the study did not find the same immediate boost for working memory. Working memory is the ability to hold small bits of information in your mind, like a phone number. This suggests that everyday movement might specifically wake up the brain’s alertness and speed, rather than its storage capacity.
The cumulative effect of small movements
One of the most encouraging findings is that these benefits add up. People who reported higher levels of everyday activity overall showed better cognitive health than those who were mostly sedentary.
This aligns with other research on “non-exercise activity thermogenesis” (NEAT), which is the energy we burn living our lives. Increasing your NEAT by taking the stairs or pacing while on the phone does not just burn calories; it keeps the brain engaged and youthful.
What you can do about it
You do not need to overhaul your schedule to use these findings. The goal is simply to sit less and move more during your normal day.
- Do your own chores: View cleaning and tidying not as burdens, but as opportunities to feed your brain.
- Walk often: Walking is the simplest way to get steady movement. Short walks count.
- Stand up: If you have a desk job, stand up and stretch or pace every hour.
- Mix it up: Combine this movement with other healthy habits like good sleep and nutrition for the best results.
