You’ve probably heard the advice to “take a deep breath” when you’re stressed, but did you know that mindful, paced breathing isn’t just a quick fix for anxiety? It’s actually a powerful practice that can have lasting benefits for both your mind and body. Whether you’re dealing with a busy day, feeling anxious, or just need a moment of calm, mindful breathing can help you feel more centered, focused, and at ease.

Let’s dive into the mind and body benefits of mindful paced breathing, and I’ll share three research-backed techniques you can start using today.


How it Helps

When you're stressed, your body enters "fight or flight" mode, triggering a release of stress hormones like cortisol. This is where paced breathing comes in. By slowing down your breath you can activate the parasympathetic nervous system (your body's "rest and digest" response), to calm the body and lower stress levels. A study published in Psychosomatic Medicine found that controlled or “paced” breathing reduces the stress response by lowering heart rate and blood pressure (Nyklicek & Thayer, 2009).


Mindful paced breathing also helps you stay more grounded in the present moment, which can prevent emotional overwhelm. Research has shown that deep, mindful breathing can activate areas of the brain linked to emotional control. When something stressful happens—like a tight deadline or a tough conversation—your brain’s amygdala (the part that detects danger) immediately goes into action. Think of the amygdala like a smoke detector—it doesn’t check if there’s a real fire, it just goes off at the slightest sign of danger. If it “smells smoke” - or rather, senses or perceives danger- it sends a signal to the hypothalamus- your brain’s control center- to get your body ready for action. 


The hypothalamus then triggers your sympathetic nervous system to release stress hormones like adrenaline and cortisol so you can deal with whatever stressor you’re facing. These hormones make your heart race, your muscles tense up, and your senses sharper so you can either fight the problem or run away from it.


A study from Psychiatry Research: Neuroimaging found that mindful breathing practices help increase the activity in the prefrontal cortex—the brain region that helps us control emotions and make decisions (Ochsner et al., 2002). 


While stress might feel like it’s taking over, your brain and body have the capacity to recover and regain balance—if you give it the right tools to do so. So, the next time you’re feeling overwhelmed, remember: the body’s stress response is natural but there’s plenty you can do to reset, calm your mind, and take back control. You can try using one of the techniques below the next time you feel stressed out, but remember, they’ll work best if practiced before the next stress episode so your brain can make note of what you want it to do differently. I recommend picking one of the three practices outlined below and practicing them either after a workout, after driving home from work, or before bed. Whenever and wherever you choose to try this out, remember, consistency is key- so do your best to commit to daily practice.


3 Research-Backed Paced Breathing Practices


Diaphragmatic Breathing (Belly Breathing)

Diaphragmatic breathing, or belly breathing, encourages you to breathe deeply into your diaphragm rather than your chest. It’s the best place to start so you can learn how to breathe in a way your body will recognize as calming instead of activating. Here's how to practice it:

  • Sit or lie down in a comfortable position.

  • Place one hand on your chest and the other on your abdomen.

  • Take a slow, deep breath through your nose and allow your belly to fill up like a balloon 

  • Exhale slowly through your nose feeling your belly “empty”

  • Pro tip: keep your shoulders and chest as still as possible; try placing your hands on your shoulders to get the hang of keeping them still while you breathe, before placing your hands back on your belly and chest


This technique is great for calming the nervous system and improving oxygen flow in the body. Studies show that diaphragmatic breathing can help lower blood pressure and reduce stress by using breath to oxygenate the blood (Jiang et al., 2016).. More oxygen = more relaxation so this is key to using breathing as a way of calming the brain and body.


Once you’ve gotten the hang of diaphragmatic breathing, try one of the paced breathing practices below:


4-7-8 Breathing

Here’s how it works:

  • Inhale quietly through your nose for 4 seconds.

  • Hold your breath for 7 seconds.

  • Exhale slowly through your mouth for 8 seconds.

This practice is known for its calming effect because of the focus on extending the exhale. Exhaling longer than you inhale is like giving your nervous system the signal to "slow down, it’s safe now." It helps activate the parasympathetic system, reducing stress and promoting a feeling of calm. It’s one of the easiest ways to shift your body out of stress mode and into relaxation mode in just a few breaths.


Box Breathing (A.k.a. Square Breathing)

Box breathing is another powerful technique, often used by athletes and even in military training to manage stress. Here's how to do it:

  • Inhale for 4 seconds.

  • Hold your breath for 4 seconds.

  • Exhale for 4 seconds.

  • Hold your breath again for 4 seconds.


It’s called "box breathing" because of the equal-length breaths that form a "box" shape. This exercise helps improve focus, mental clarity, and emotional regulation. It’s also been shown to reduce symptoms of anxiety in both clinical and everyday settings (Saoji et al., 2019).


So, the next time you’re feeling overwhelmed or need to reset, try out one of these breathing techniques. With consistent practice, you’ll be well on your way to a calmer, clearer, and more focused you. Taking a few minutes each day to focus on your breath can make a big difference. And the best part? It’s totally free and easy to do anywhere, anytime.
