You have probably felt it before without having a name for it. That particular lightness that arrives sometime in March or April when you find yourself actually wanting to go outside again, to move your body, to call a friend, to eat something that did not come wrapped in plastic. It turns out that feeling is not just seasonal nostalgia. Virginia Tech associate professor Ben Catz, whose research focuses on interventions to improve executive function and cognitive aging, says spring matters for your brain not because of what the season is but because of what it makes you more likely to do. And those choices, repeated over time, add up to something profound.
What Cognition Actually Means and Why It Matters
Before diving into what helps, it helps to understand what we are actually talking about. Cognition is an umbrella term covering all the mental processes involved in thinking. That includes attention, memory, executive function, and processing speed. These are the capacities that shape how clearly you think, how well you focus, how quickly you solve problems, and how effectively you move through your day.
Most of us do not think about cognition until something feels off. But the research Catz discusses in his Virginia Tech Curious Conversations podcast episode makes a compelling case for tending to your cognitive health proactively, the same way you might tend to your physical fitness or your emotional wellbeing. The good news is that many of the best things you can do for your brain are also things that simply make life feel better.
Cardiovascular Exercise Is One of the Deepest Gifts You Can Give Your Brain
When Catz talks about exercise and the brain, he keeps returning to cardiovascular activity specifically. Running, biking, swimming, hiking, anything that gets your heart pumping. The reason is more direct than most people realize. Your brain is highly vascularized, meaning it depends on a constant supply of oxygenated blood to function well. Your cardiovascular system is what delivers that blood.
Exercise also triggers the release of brain-derived neurotrophic factor, or BDNF, a compound that supports learning and neurological health. So when you go for a brisk walk or a run, you are not just burning calories. You are essentially feeding your brain. The cardiovascular connection also explains why the link between heart health and brain health is so consistent across research. What is good for your heart is very often good for your mind.
Nature Restores What Overstimulation Quietly Drains
There is a growing body of research suggesting that spending time in quiet green spaces, think walking through a forest with bird calls overhead and minimal digital noise, can restore your capacity for attention. The theory is that urban and screen-heavy environments constantly tax your directed attention, the focused mental effort you use to get things done. Nature, by contrast, engages a softer, more effortless kind of attention that allows the directed kind to recover.
Catz is careful to note that researchers are still mapping the exact mechanisms and conditions under which this works. But the practical picture is encouraging. Even looking at images of natural settings may offer some benefit. And when you combine a walk in nature with cardiovascular exercise, you are stacking two well-supported cognitive benefits at the same time. That combination, he says, is probably one of the best situations you can put yourself in.
The Foods That Most Affect Your Long-Term Brain Health
Diet is an area where the research is both reassuring and specific. Catz and his colleagues have found that adherence to Mediterranean and DASH dietary patterns, both of which emphasize lean proteins, whole grains, fruits, vegetables, and low sodium, is associated with less cognitive decline as people age. The pattern as a whole matters more than any single food.
But their research into ultraprocessed foods turned up some particularly notable findings. Of all the ultraprocessed foods studied, two were most strongly linked to increased dementia risk when consumed regularly. Processed animal products like deli meats, which tend to be high in sodium and nitrates, and sugar-sweetened beverages. The increase in risk for regular daily consumers was significant. The takeaway is not to panic over a hot dog on a holiday. It is to look honestly at your everyday patterns and consider where small, consistent shifts might protect your future self.
Sleep Is When Your Brain Does Its Most Important Work
Sleep is the one area Catz says most people underestimate as a cognitive health behavior. It is during sleep that memory consolidation happens, meaning the experiences, skills, and information you took in during the day get organized and stored. Both the amount and the quality of your sleep matter, and quality often gets overlooked.
Uninterrupted sleep, falling asleep without too much delay, and staying asleep through the night are all markers of restorative rest. Catz points out that regular exercise improves sleep quality, which creates a reinforcing loop. He also highlights sleep hygiene practices like putting your phone in another room and stepping away from screens before bed. These are not just suggestions for better rest. They are evidence-backed strategies for protecting your cognitive performance over time.
Social Connection and Reducing Distraction Are Underrated Cognitive Tools
Two more factors round out Catz's picture of brain-healthy living. Social engagement, whether through team sports, board games, volunteering, or simply spending real time with people you care about, is consistently linked to better cognitive function in older adults. The reasons are layered. Social interaction supports emotional health, provides cognitive stimulation, and increases the likelihood that you will stick with other healthy behaviors.
Then there is distraction. Catz himself has become intentional about reducing the number of notifications and interruptions in his daily life, even using a phone with a physical switch to block them entirely. Your ability to sustain focused attention is a cognitive resource. Every unnecessary interruption draws on that resource. Creating even small pockets of uninterrupted time, ideally outdoors, is something you can start doing today.
What a Brain Health Researcher Actually Does for His Own Brain
One of the most grounding parts of the conversation is hearing what Catz personally practices. He walks in a nearby garden when he feels cognitive fatigue building. He has eliminated soda from his diet. He manages distraction deliberately. He exercises regularly and understands that no single behavior is a silver bullet. The research, he says, consistently points toward multimodal approaches: combining exercise with diet, social engagement with cognitive stimulation, rest with intentional presence.
That is the real message spring carries. Not that the season is magical on its own, but that it opens a door. It lowers the activation energy for the habits that matter most. Walking outside, moving your body, eating something fresh, calling a friend. These are the behaviors the research supports. And spring, with its longer light and warmer air, makes all of them feel just a little more possible.

Article Recap
Spring brain health benefits are less about the season itself and more about the lifestyle habits it encourages, including cardiovascular exercise for cognitive function, time in nature for attention restoration, and dietary patterns that reduce dementia risk. Research from Virginia Tech shows that combining regular aerobic movement, quality sleep, social engagement, and reduced distraction creates a multimodal approach to protecting and improving brain cognition at any age. If you are looking for practical ways to improve your brain health naturally, the science suggests starting with the simple choices spring already makes easy.
