What if managing your emotions in stressful situations was as simple as breathing—literally? According to a recent study published in Psychological Reports, it might be. Researchers found that doing a slow, focused breathing exercise for just three minutes helped people feel less rattled by negative images—and even made them better at handling their emotions afterward.
The Power of a Deep Breath
We all know what stress feels like: sweaty palms, a racing heart, maybe a few choice words muttered under your breath. But what’s happening inside your body is more complicated. Stress flips a biological switch, activating what scientists call the hypothalamic-pituitary-adrenal (HPA) axis. This chain reaction releases stress hormones—like cortisol—that rev up your body but also mess with your brain, especially the part in charge of staying calm and making good decisions.
That part of your brain, the prefrontal cortex, usually acts like a wise referee during emotional chaos. But under stress, its voice gets drowned out. You might snap, panic, or mentally spiral because your brain’s emotion-control center has lost its grip.
But here’s the twist: calming your body might help your brain take the wheel again. That’s where slow breathing comes in.
Why Breathing Slowly Works
Slowing your breath activates the parasympathetic nervous system, which is science-speak for the body’s “chill-out” mode. This system works through the vagus nerve, a major nerve highway that helps control your heart rate and digestion. When you breathe slowly and deliberately, you send a signal to your body that it’s safe. As a result, your heart slows, your mind clears, and your emotional grip strengthens.
This study wanted to see if a super-short breathing session—just three minutes—could have immediate emotional benefits. Could it make people not just feel better, but also think better about their feelings?
Turns out, yes.

The Experiment, Made Simple
Thirteen college students took part in this small but revealing study. Each student completed two separate sessions over video chat. In one session, they jumped straight into the task. In the other, they began with a guided breathing exercise.
The breathing technique was “box breathing”—inhale for 4 seconds, hold for 3, exhale for 4, hold again for 3, and repeat. The animation on-screen helped them keep pace for the full three minutes.
Next came the main event. Participants were shown a mix of upsetting and neutral images (think: accidents versus bland objects). Before each image appeared, they heard one of three instructions:
- Enhance: Try to feel the emotion more deeply—imagine you or a loved one in the scene.
- Suppress: Try to tone down your emotion—think of the image as fake or focus on something non-emotional.
- Maintain: Just look at it and feel what you feel, naturally.
After viewing each image, participants rated how they felt: Was the image pleasant or unpleasant? Did it excite or calm them? They also rated how well they thought they followed the instruction—basically, how in-control they felt.
What the Breathing Did
Here’s where it gets interesting.
Participants who did the breathing exercise felt less negative and more calm when asked to just “maintain” their reaction. In other words, breathing helped soften their initial emotional blow. Without doing anything fancy—no mental trickery—they were already in a better place emotionally.
Even more revealing was how well they felt they handled their emotions when actively trying to enhance or suppress them. Normally, people find it harder to “suppress” negative emotions than to enhance or just maintain them. That held true in the session without breathing—participants felt they weren’t great at dialing down their reactions.
But after breathing? That difficulty disappeared. Participants rated themselves as being just as good at suppressing as they were at enhancing or maintaining. The breathing made them feel like they had more emotional control. It didn’t just change how they felt—it changed how confident they were in managing their own feelings.

For People Who Avoid Tough Emotions
The researchers also looked at personality differences. Some people tend to avoid negative situations more than others. Unsurprisingly, those people struggled to “enhance” their feelings toward upsetting images in the no-breathing condition. They didn’t want to lean into the discomfort.
But after the breathing exercise, even those avoidant folks could engage more fully. It seems that calming the body gave them a sense of emotional safety, making it easier to interact with uncomfortable thoughts or feelings without shutting down.
Not a Perfect Study, But a Promising Start
As exciting as the findings are, the researchers admitted that their study has some limitations.
For starters, only 13 participants were involved—hardly enough to draw sweeping conclusions. Also, the breathing was so effective that emotional ratings in the “maintain” condition were already extremely low, making it tough to see if cognitive strategies added any extra benefit. This is called a “floor effect”—basically, the ratings hit rock bottom, so there was nowhere else to go.
The study didn’t measure heart rate or brain activity either, so it couldn’t confirm whether the nervous system was actually calming down the way scientists suspect.
But these limitations don’t cancel the impact. Instead, they highlight directions for future research—like testing more intense emotional stimuli, using physical sensors to measure relaxation, and comparing different breathing styles.
Final Inhale: Why This Matters
It might sound almost too simple to be true, but the breath—something we do automatically thousands of times a day—might be one of the most underappreciated tools for emotional strength and mental clarity.
In a world that often pushes us to go faster, react quicker, and juggle more, it’s rare to hear advice that says: “Slow down. Breathe. That’s enough.” But this research gently reminds us that our breath isn’t just air—it’s a built-in calming mechanism, a bridge between our body and mind that we can access anytime, anywhere.

Why does this matter? Because life throws curveballs constantly. A bad email, an argument, a social media post that ruins your mood—it doesn’t take much to send our nervous systems into overdrive. And while we may not always be able to control what happens around us, we can control how we respond. That’s where breathing steps in, not as a grand solution, but as a humble companion that steadies the ship when waters get rough.
What this study adds to the conversation is the idea that calming our body through breathing isn’t just about feeling relaxed in the moment. It’s about creating space—space to think before reacting, to approach emotions with intention, and to gain confidence in our ability to handle them. Even more remarkably, it suggests that this shift doesn’t require weeks of meditation retreats or expensive stress-relief gadgets. Three minutes of box breathing can already nudge our emotional compass back to center.
