Study Highlights Benefits of Slow Breathing for Emotional Regulation
A recent study published in Psychological Reports has found that just three minutes of slow, controlled breathing can enhance how we manage our emotional responses to distressing situations. After engaging in a brief breathing exercise, participants felt less negative and less agitated while viewing unpleasant images. Additionally, they reported feeling more capable of employing mental strategies to shift their emotional state, which indicates that this straightforward technique might offer an immediate boost to emotional self-regulation.
Researchers have long recognized that emotional management is crucial for mental health and coping with life’s challenges. When a person’s ability to regulate emotions is compromised, it can be linked to various mental health concerns like depression and anxiety. There’s a complex, back-and-forth relationship between stress and emotional control—high stress can hinder our ability to manage feelings, while poor emotional regulation can exacerbate stress.
This impairment occurs through a specific biological pathway. Stress activates the body’s central stress response system, the hypothalamic-pituitary-adrenal (HPA) axis, leading to the release of stress hormones like cortisol. These hormones can disrupt functioning in the brain’s higher-order thinking areas, particularly the prefrontal cortex, which oversees executive functions such as self-control and decision-making. This interference reduces the “top-down” control our rational brain typically has over automatic emotional responses, making it harder to remain composed and logical.
Considering this connection, the researchers hypothesized that finding a way to calm the body’s stress response could free up mental resources for better emotional regulation. One promising approach is slow-paced breathing, which activates the parasympathetic nervous system, responsible for the “rest and digest” response that calms the body. This effect occurs by boosting vagus nerve activity, which helps regulate heart rate and other internal functions.
The study aimed to address some gaps in existing research. While many studies have touched on mindfulness, they often involve lengthy training or just ask participants to focus on their breath without intentionally slowing it down. This research examines whether a short session of slow-paced breathing could produce immediate results.
Additionally, past studies have frequently looked at how breathing impacts baseline emotional states, but they didn’t assess whether it improved active strategies like cognitive reappraisal—changing how you think about a situation to alter your feelings. The researchers also wanted to explore emotional flexibility, asking participants to reduce as well as intensify negative feelings, which hasn’t received much attention in emotional control studies.
The team conducted experiments with 13 undergraduate students from a New England college, averaging around 21 years old. Utilizing a “within-subjects” design, each participant experienced both the experimental and control conditions, allowing for direct performance comparisons. The two sessions were held online with one to two weeks in between.
The order of conditions varied to avoid any bias. In both sessions, participants completed a cognitive reappraisal task, viewing a series of negative and neutral images. Before each image, they listened to instructions to either “enhance,” “suppress,” or “maintain” their emotional reactions.
For the “enhance” instruction, they were encouraged to amplify their emotional response, perhaps by imagining themselves or a loved one in that situation. Conversely, for “suppress,” they were guided to reduce their emotional response by thinking of the situation as fictional or focusing on a neutral detail. The “maintain” instruction simply asked them to observe the image and let their emotions flow naturally.
The main difference between the two sessions was the introduction of the slow-paced breathing exercise in the experimental condition. Before starting the picture task, participants practiced a three-minute “box breathing” technique guided by an on-screen animation.
After viewing each image, participants provided multiple ratings using the Self Assessment Manikin tool, assessing their feelings towards the pictures on a 9-point scale for valence and arousal. They also rated how successfully they felt they had followed the instructions for emotional response.
The breathing exercise positively impacted participants’ emotional states. Those instructed to “maintain” their reactions to negative images reported viewing the pictures as less negative and felt calmer when they had completed the slow-paced breathing exercise, compared to the control condition. This suggests that the breathing technique acted as an emotional buffer, diminishing the immediate impact of unpleasant stimuli.
Interestingly, the findings revealed that the breathing exercise enhanced cognitive reappraisal use. In the control condition, participants felt notably less successful at suppressing negative emotions compared to enhancing or maintaining them. They experienced difficulty in distancing themselves from their feelings.
After the slow-paced breathing exercise, however, this struggle vanished. Participants felt equally adept at enhancing, maintaining, and suppressing their emotions. Compared to the control condition, they rated themselves as more successful in suppressing their emotional reactions to negative images post-breathing exercise, suggesting that the breathing improved their sense of control and confidence in managing their feelings.
The study also highlighted the exercise’s benefits for individuals who typically avoid negative situations. Participants with higher scores on a measure of the Behavioral Inhibition System, indicating a tendency to shy away from aversive stimuli, struggled with the “enhance” instruction in the control condition. Following the slow-paced breathing exercise, they were just as capable of enhancing their emotional experiences as the other participants, implying that the calming effect of breathing may create a sense of safety that encourages engagement with uncomfortable emotions.
While the authors noted some limitations, such as the small sample size of 13, they emphasized that these findings need to be replicated in larger, more varied groups. A notable limitation was the potential “floor effect”; participants’ negative feelings and arousal levels were so low after the breathing exercise that it limited further reduction. This made it tricky to assess the additional benefits that cognitive reappraisal might provide.
Future research could explore the effects using more intense negative stimuli and should incorporate direct physiological measures, like heart rate variability, to confirm that the emotional benefits correlate with increased activity in the calming parasympathetic nervous system. It could also be beneficial to compare different breathing techniques and paces to enhance the intervention’s efficacy.
The study, titled “Acute Effects of Slow-Paced Breathing on Emotion Regulation: A Pilot Study,” provides intriguing insights into the potential of a simple breathing exercise to improve emotional regulation.
