Two Strategies, Two Very Different Outcomes
Many people were taught — directly or indirectly — that managing emotions means keeping them under control. But there's a crucial distinction between controlling emotions in a healthy way and simply burying them. Understanding what emotions actually are is a useful starting point, because how we define our inner experiences shapes how we respond to them.
Emotional regulation refers to the ability to notice, understand, and constructively influence how you experience and express emotions. It doesn't mean feeling less — it means relating to your feelings in flexible, purposeful ways. Strategies like naming an emotion, practicing mindful breathing, or reframing a situation are all forms of regulation.
Emotional suppression, by contrast, involves deliberately pushing feelings out of awareness — essentially refusing to acknowledge that an emotion is happening. On the outside, both approaches can look like staying calm. On the inside, they're physiologically and psychologically quite different.
| Criterion | Emotional Regulation | Emotional Suppression |
|---|---|---|
| Core approach | Acknowledge and skillfully manage | Push feelings out of awareness |
| Emotional awareness | High — feelings are named and processed | Low — feelings are avoided or denied |
| Short-term effect | May feel uncomfortable initially | Provides temporary relief |
| Long-term mental health impact | Builds resilience and wellbeing | Associated with increased stress and anxiety |
| Effect on relationships | Supports authentic connection | Can create distance and inauthenticity |
| Physical health links | Associated with healthier stress responses | Linked to elevated cardiovascular reactivity |
| Can be learned and improved? | Yes — research-supported strategies exist | Pattern can be unlearned with practice |
What the Research Says About Suppression
Decades of research in emotion science have consistently linked habitual suppression to measurable costs. Studies published in peer-reviewed journals have found that people who regularly suppress emotions show heightened cardiovascular reactivity — meaning their hearts and blood pressure respond more strongly to stress, even when they appear outwardly composed. Over time, this kind of chronic internal effort can contribute to elevated stress hormones and immune system changes.
Suppression also tends to be socially isolating. When you consistently mask what you feel, it becomes harder for others to connect with you authentically, and you may find relationships feel more distant or hollow. There's also evidence that suppressing an emotion doesn't reduce its intensity — it can actually amplify it, a phenomenon sometimes called the rebound effect.

Higher physiological stress in suppressors
Research in the Journal of Personality and Social Psychology found emotion suppressors showed significantly greater physiological arousal during stressful tasks compared to non-suppressors.

Rebound intensity after suppression
Studies in experimental psychology have found that suppressed thoughts and emotions tend to return with greater intensity — a well-documented phenomenon known as the rebound effect.
It's worth noting that not every moment of emotional restraint is suppression. Choosing not to express anger in a tense professional setting, for example, while later processing that anger in a healthy way, is closer to regulation than suppression. The key difference is whether the emotion is eventually acknowledged and processed, or simply buried.
Building Regulation Skills in Everyday Life
The encouraging news is that emotional regulation is a learnable skill, not a fixed personality trait. Research on neuroplasticity — the brain's ability to reorganize itself — supports the idea that practicing regulation strategies can, over time, change how your brain responds to emotional triggers. You can read more about identifying what sets your emotions in motion in our article on recognizing your emotional triggers.
Practical regulation strategies supported by clinical research include:
- Labeling emotions: Research by psychologist Matthew Lieberman and colleagues suggests that simply naming what you feel — "I'm feeling anxious" — can reduce the intensity of the emotional response in the brain.
- Cognitive reappraisal: This involves reinterpreting a situation to shift its emotional meaning. For example, viewing a difficult conversation as an opportunity for understanding rather than a threat.
- Mindful awareness: Observing emotions without immediately judging or acting on them creates a pause — what some researchers call a "response window" — between feeling and action.
For a deeper look at how these patterns play out in real interactions, our piece on reactive vs. responsive emotional responses explores how regulation shapes the choices we make in difficult moments.
If you find that emotional suppression is a deeply ingrained pattern — particularly if it's tied to past experiences or trauma — working with a licensed mental health professional can offer personalized support.
