Ten minutes of jogging so slow you could almost walk beside it was enough to lift mood and sharpen focus in a new brain-imaging study. Participants ran at roughly 2 to 4 miles per hour, and afterward they felt better, did better on a classic focus test, and showed more activity in the brain’s “control center.”
The research, from Japan’s University of Tsukuba and published in the journal Imaging Neuroscience, makes a strong case for slow jogging as a tiny, low-effort starter move on days you don’t feel like doing anything at all. Here’s what the scientists found, what it can’t tell us yet, and a 10-minute plan you can try today.
What the Slow Jogging Study Found
Researchers recruited 24 healthy young adults and tested each of them on two separate days. On one day, they sat quietly on a treadmill for 10 minutes. On the other, they ran on it for 10 minutes at a very slow pace.
According to the University of Tsukuba announcement, the run was set at about 3-6 km/h (about 1.9-3.7 mph), “a pace close to walking.” That works out to a very light intensity of roughly 35% of peak oxygen uptake. Average heart rates stayed around 105-107 beats per minute, Fox News Digital reported.
After just 10 minutes of slow running, compared with resting:
- Mood improved. Participants reported feeling more alert and more pleasant.
- Focus sharpened. They were faster on the Stroop test, where you name the ink color of a word like “RED” printed in blue. It’s a standard measure of executive function, the mental skills behind attention and self-control.
- The brain lit up. Brain imaging (functional near-infrared spectroscopy, or fNIRS) showed more activity in the left dorsolateral prefrontal and left frontopolar cortex, areas tied to focus and mood regulation.
The study was led by Hideaki Soya, professor emeritus at Tsukuba, with assistant professor Ryuta Kuwamizu and lecturer Chorphaka Damrongthai. “Notably, the increase in pleasant mood was particularly strong, suggesting that slow running may be especially effective at improving how people feel,” the researchers told PsyPost.
The “Bounce” That May Make Running Feel Good
Here’s the quirkiest finding. During a separate two-minute run, the team attached a small sensor to measure each runner’s up-and-down head movement. People who bounced more tended to report a bigger boost in pleasant mood.
The researchers told PsyPost the finding raises “the possibility that the gentle bouncing rhythm characteristic of running may itself contribute to why running feels good.” They stressed that the head motion reflects the rhythm of the whole body, not just the head.
Important: this link is exploratory and correlational. It doesn’t prove that bouncing causes the mood lift. But it hints at why a slow jog might feel different from a stroll, even at the same speed.
Why Slow Jogging Is a Motivation Hack
Most of us wait to feel motivated before we move. This study flips that script. The participants didn’t need to be fired up or fit to get a benefit. They just needed to start, and the better mood came after the movement.
That lines up with a theme we keep coming back to: motivation often follows action, not the other way around. (We dug into the science behind that in The Myth of Motivation: Why Action Comes First.)
Think of slow jogging as a “minimum effective dose.” It’s small enough that your brain can’t easily argue with it:
- No warm-up drama. You’re moving at a walking-compatible speed.
- No gym required. A sidewalk, hallway or park loop works.
- Only 10 minutes. That’s shorter than most social media scroll sessions.
“If you have avoided running because it seems too demanding, slow running may offer a very accessible way to begin,” Soya and Kuwamizu told PsyPost.
What This Slow Jogging Study Can’t Tell Us
Before you rebuild your life around 10-minute jogs, know the limits. The authors and outside experts were upfront about them:
- It’s small. Just 24 people.
- It’s young and healthy. Results may not apply to older adults, beginners or people with health conditions.
- It’s short-term. Researchers measured effects right after a single session, not over weeks or months.
- No walking comparison. Running was only compared with sitting, so it’s hard to separate the effect of running from simply being up and moving.
- Imaging limits. The fNIRS setup lacked special channels that filter out scalp blood flow, though the team used timing and analysis methods to reduce that noise.
The researchers also warned against overreading it. “Please do not read this as ‘slow running is better than harder running’ or as a claim that everyone should switch to slow running,” they told PsyPost. Their point is about the floor, not the ceiling: benefits can show up even at the very lowest intensity.
Dr. Scott Nass, a California family medicine physician not involved in the study, told Fox News Digital the effect is likely temporary, and that for people living with depression or anxiety, a jog is “no substitute for medical care.”
Where “Niko Niko” Slow Jogging Fits In
Slow jogging isn’t a brand-new idea. Dr. Hiroaki Tanaka of Fukuoka University in Japan popularized a style he called “niko niko” running. “Niko niko” means smiling in Japanese, and the idea is to jog at a pace easy enough to smile and hold a conversation.
The Tsukuba team’s work also builds on its own earlier research. Their release notes that a previous study found a 10-minute bout of very light exercise could enhance memory linked to the hippocampus (Suwabe and Soya, PNAS, 2018). The new paper extends that “small dose, real effect” idea to running.
Your 10-Minute Slow Jogging Starter Plan
Want to try it? Here’s a simple plan built from the study’s setup and expert tips. Keep it easy. If you can’t talk in full sentences, slow down.
- Minutes 0-2: Walk. Loosen up at a normal walking pace.
- Minutes 2-8: Shuffle-jog. Switch to a running form with small, light steps, at a speed barely faster than your walk. Let yourself gently bounce.
- Need a break? Mix it up. Internist Dr. John La Puma suggested adding 30-second jogging intervals to a walk, at a pace that lets you speak in full sentences without getting breathless, according to Fox News Digital.
- Minutes 8-10: Walk it out. Ease back to a stroll.
- Then do the hard thing. Head straight into the task you’ve been avoiding while the boost is fresh.
La Puma’s practical tip: take your 10-minute move outdoors before the most mentally demanding part of your day. Think pre-presentation, pre-study session or before tackling your inbox.
If you miss a day, don’t scrap the plan. Adjust it and try again, the core of the iterative mindset that research links to stronger habits over time.
Make It Stick: Stack It and Track It
The study looked at one session, so the habit part is up to you. A few low-friction ways to make slow jogging automatic:
- Anchor it. Attach your 10 minutes to something you already do, like right after your morning coffee or right before you open your laptop.
- Lower the bar on purpose. On rough days, the goal is just shoes on and out the door. Two minutes still counts as showing up.
- Notice the after-feeling. Jot down your mood before and after for a week. Seeing your own “before vs. after” can be more convincing than any study.
There’s a bonus, too. Moving regularly may pay off at night: a large study we covered found that starting a workout habit was linked to 37% higher odds of feeling rested (read more about exercise for better sleep).
The Bottom Line
You don’t need to run fast, run far or even feel motivated to get a mental lift from moving. In this small study, 10 minutes of slow jogging at near-walking speed boosted mood, sharpened focus and activated key parts of the brain in healthy young adults.
It’s early science, not a cure-all. But it’s a low-risk, zero-cost experiment you can run on yourself this week. Lace up, go slow, and let action do the motivating.
Quick safety note: La Puma advised that people with heart disease, high blood pressure, type 1 diabetes, recent surgery or joint pain consult a clinician before starting a new exercise routine.
