What is emotional dysregulation in adults? It is the difficulty managing the intensity or duration of emotions, which feel overwhelming and lead to reacting in ways you later regret. It is not a diagnosis: it can be a temporary state caused by stress or tiredness, and there are strategies that help restore calm.
Imagine an ordinary Tuesday. You have slept badly, the bus is late and, at work, someone makes an unimportant remark about your report. Suddenly you notice a heat rising in your chest, your voice hardens and you respond with a brusqueness you do not recognise. Ten minutes later, once you have calmed down, you wonder what happened. On social media, this scene has been given a name: "my nervous system is dysregulated." The expression has become as popular as it is imprecise. It is worth separating what psychology knows from what has been added along the way.
What is emotional dysregulation?
Emotional dysregulation is the difficulty modulating emotions so that they fit the situation and your goals: feeling them with an intensity that is hard to manage, taking a long time to subside, or leading you to act impulsively. It is the opposite of emotional regulation, the ability to influence which emotions we feel, when, and how we express them.
Emotions are normal and useful responses to what matters to us, as the American Psychological Association explains. The problem is not feeling them, but the relationship we have with them. Regulating does not mean suppressing: it means being able to feel an emotion without letting it decide for you.
Psychologists Kim Gratz and Lizabeth Roemer proposed one of the most widely used definitions in research in 2004, in the Journal of Psychopathology and Behavioral Assessment. According to their model, regulation difficulties can manifest in several ways: not accepting one's own emotions, having trouble concentrating or controlling impulses when upset, being unclear about what one feels, or feeling that there are no strategies to calm down. That idea is important: dysregulation is not a single thing, but a set of distinct difficulties.
If you would like to review what emotions are and what they are for, you can read what emotions are and why they are key to your emotional well-being.
Is it a disorder or a temporary state?
Emotional dysregulation is not a disorder or a diagnosis: it does not appear as such in the reference diagnostic manuals, the DSM-5-TR and the ICD-11. It is a difficulty that anyone can experience at times of stress, tiredness or crisis, and which in some cases persists over time.
It is helpful to think of it as a continuum. At one end are occasional outbursts: a bad day, a sleepless night, an argument that catches you off guard. At the other, a persistent pattern that affects relationships, work or well-being. A review by Amelia Aldao, Susan Nolen-Hoeksema and Susanne Schweizer, published in 2010 in Clinical Psychology Review, found that strategies such as rumination, avoidance and suppression were associated with more symptoms across different mental health problems, such as anxiety, depression or issues with food and substances. For this reason, regulation difficulties are considered a process shared by different psychological problems, not a problem in themselves.
Having emotional outbursts does not mean you have a disorder, just as having a day of intense anxiety does not mean you have an anxiety disorder. Putting a label on it in time can help you understand yourself; turning it into an identity, not so much.
What signs indicate that I struggle to regulate my emotions?
Some common signs are reacting with an intensity that later seems disproportionate to you, taking a long time to recover from anger or sadness, or feeling that emotions decide for you. Rather than a checklist, they are clues for observing yourself with curiosity.
Among the experiences that are often described:
Going from calm to anger or tears in a very short time.
Feeling that an emotion takes hours or days to subside.
Acting impulsively when you are upset and regretting it afterwards.
Having difficulty knowing exactly what you feel, beyond "I feel bad."
Avoiding situations, people or conversations so as not to feel something uncomfortable.
Going over and over what upset you.
Turning to food, alcohol, shopping or screens to switch off what you feel.
These signs do not reveal whether there is a mental health problem behind them: only a professional can make that assessment. If you would like to reflect on how you manage your emotions, the emotional regulation test from Psicología y Mente can be a good starting point, without replacing a professional evaluation.
Why does it happen? Triggers and causes
Emotional dysregulation does not have a single cause. It has been associated with situational factors, such as tiredness or stress, and with more stable factors, such as temperament, personal history or some mental health problems.
Among the most common triggers are:
Sleep. A study by Seung-Schik Yoo, Matthew Walker and their team, published in 2007 in Current Biology, found that after a sleepless night the amygdala, a brain region involved in the emotional response, reacted more intensely to unpleasant images. Sleeping poorly has been associated with greater emotional reactivity.
Accumulated stress, which leaves less room to cope with the unexpected.
Hunger, pain or physical discomfort, which can reduce frustration tolerance.
Alcohol or other substance use.
Reminders of difficult experiences, such as situations resembling past conflicts or losses.
As for the more stable factors, psychologist Marsha Linehan proposed in 1993 a biosocial model according to which emotional dysregulation would arise from the interaction between heightened emotional sensitivity and an environment that invalidates emotions, for example by minimising or punishing them. It is one of the most influential hypotheses, although it does not explain all cases. Regulation difficulties are also common in people with ADHD, with traumatic experiences or with certain personality disorders, without that meaning that someone who has emotional outbursts has any of these conditions.
What does science say about the language of a "dysregulated nervous system"?
The expression "dysregulated nervous system" has become popular on social media as a way of describing stress or emotional outbursts, but it is not a clinical term. It is a metaphor that may help some people understand what they feel, although it is often presented with more certainty than the research supports.
Much of this language comes from polyvagal theory, proposed by psychiatrist Stephen Porges in the 1990s, which links different states of the vagus nerve with safety, fight-or-flight and shutdown. The theory has been very influential in the therapeutic field, but also much debated: in 2023, researcher Paul Grossman published in Biological Psychology a critical review questioning its physiological and evolutionary premises. Another widely circulated concept, the "window of tolerance," proposed by psychiatrist Daniel Siegel, is used as a useful clinical metaphor to describe the range within which a person can manage their emotions, not as a physiological measure.
What is well established is that emotions involve the body: heart rate, breathing and muscle tension change with them, and working with the body, for example by breathing slowly, can help lower activation. The problem is not using the language of the body, but turning it into a diagnosis or a closed explanation for everything we feel.
What strategies help restore calm after an outburst?
The most useful thing in the moment is to lower physical activation, name what you feel and give yourself time before acting. In the medium term, looking after your sleep and practising regulation skills when you are calm helps make outbursts less frequent or intense.
In the moment
Before acting. A pause of a few minutes, leaving the room or postponing a response can prevent reactions you later regret.
Breathe slowly. Lengthening the exhalation is one of the techniques used in therapy to reduce physical activation.
Move your body. Walking briskly or climbing a few stairs can help release tension.
Name the emotion precisely. Research on "emotional granularity," reviewed by Todd Kashdan, Lisa Feldman Barrett and Patrick McKnight in 2015, has associated the ability to distinguish between similar emotions, such as frustration, disappointment or shame, with less impulsive coping styles.
Day to day
Look after your sleep, food and rest. They are the foundation on which everything else rests.
Reframe situations. Asking yourself "is there another way to see this?" is a strategy that, in the studies by James Gross and Oliver John (2003), was associated with greater well-being than suppressing the expression of emotions.
Reduce rumination. If you catch yourself going over what happened, bringing your attention to a specific activity usually helps more than continuing to analyse.
Practise when you are calm. The techniques work better in a difficult moment if you have trained them beforehand.
When is a professional evaluation advisable?
It is advisable to consult a professional when outbursts are frequent, last a long time or affect your relationships, your work or your well-being, or when you turn to behaviours that harm you in order to calm down. An evaluation helps to understand what lies behind it and to find the right tools.
Some psychological approaches specifically work on emotional regulation skills. Dialectical behaviour therapy, developed by Linehan, includes skills training to tolerate distress and regulate emotions, and cognitive behavioural therapy helps identify and change the patterns that maintain outbursts.
