The argument ended last night; you slept well afterwards, but why are you still exhausted this morning? You wake up tired; your head feels foggy; you’re replaying conversations from last night, feeling sensitive, like you need a day to recover, just stay in bed, even though the problem is already solved. It’s almost like a hangover, but you’re hungover on emotions.
While the term “hangover” is usually associated with the feeling of physical and mental aftermath of drinking, people sometimes borrow the term to describe a similar feeling after an emotionally intense or significant experience or event in life. There is no standard definition for an emotional hangover; however, the term is used informally to describe when an event or experience is over but leaves behind lingering emotions (Lyons, 2025).
Many people, at some point in life, find themselves sitting with this feeling, so it makes sense that it has a name many people can relate to, but are emotional hangovers actually real, or are they simply a metaphor for the lingering effects of an intense emotional experience? This article explores the scientific basis behind experiencing an “emotional hangover” to find out.
What is an Emotional Hangover
While psychology has no official definition or recognition of an emotional hangover, many people experience it, which has led to conversations about what it is and how to deal with it. Emotional hangovers can be due to negative experiences like a bad day or an argument, but they can also result from positive experiences, like after a fun event such as a concert or the day after a wedding or a big party.
Everything went well; everyone had fun, laughed, danced, sang, ate well, and went home, but the next day, there’s more than physical exhaustion. People keep replaying conversations, moments, what made them cry, what made them laugh, that one relative they met after five years. Being a relatively new term, many psychologists and counsellors differ on what an emotional hangover feels like, but the commonly mentioned feelings are:
The American Psychological Association (APA) defines emotions as a “complex reaction pattern, involving experiential, behaviour and physiological elements, by which an individual attempts to deal with a personally significant matter or event” (APA Dictionary of Psychology, n.d.). A hangover from drinking usually occurs within hours after heavy drinking and lasts up to a day (APA Dictionary of Psychology, n.d.-b).
Together, these definitions suggest what an emotional hangover is and that it differs from feeling tired or fatigued and is not an emotion itself. Rather, the term is used to describe the lingering physical, cognitive, and emotional effects that may remain after a significant emotional experience ends. However, is an emotional hangover possible, or is it just a metaphor? Can an emotional experience actually leave effects that persist even after the event is over?
Do Emotions Linger?
To understand whether an emotional hangover has a scientific basis, it helps to look at how emotional experiences affect memory and what they leave behind after an emotionally significant event is over. Emotional arousal refers to how strongly an emotion activates the mind and body. It can be a positive or negative experience or event, such as an argument, a fun concert, a frightening experience, or receiving unexpected good or bad news.
A 2004 review of animal and human research on memory consolidation and amygdala activity found that emotionally arousing experiences activate the amygdala and related neuromodulatory systems, which can enhance memory consolidation into long-term storage. In short, emotionally significant events and experiences are remembered better and longer than ordinary experiences because they activate the amygdala, which supports memory consolidation (McGaugh, 2004).
Biopsychological research also shows that emotional experiences, particularly stressful ones, can produce changes in both the body and emotional state. A meta-analysis of 61 studies using the Trier Social Stress Test (TSST), a standardised laboratory procedure that induces acute psychological stress through socially evaluative tasks such as public speaking, found that acute stress was associated with changes in both biological and emotional measures.
Cortisol, one of the stress hormones, and negative mood were particularly sensitive markers during the stress response and recovery (Man et al., 2023). This suggests that the effects of a stressful experience may not disappear the moment the stressor ends; instead, the body and emotional state may take time to return to baseline.
But what about the emotion itself? Can an emotional state persist beyond the event that caused it, contributing to the feeling of an emotional hangover? The psychological concept of emotional inertia comes close to an emotional hangover. Emotional inertia is the tendency of a current emotional state to persist from one moment to the next (Kuppens et al., 2010).
A 2015 study of 200 college-level students found that people with greater negative-affect inertia tend to recover more slowly after negative emotional events (Koval et al., 2015). While the study does not discuss emotional hangover, it shows that the emotional response to an event may not end when the event ends. This also helps explain why conversations around emotional hangover focus more on negative experiences than on positive ones. But what determines whether an emotional response lingers?
What Makes Emotions Linger?
A 2025 study examined emotional experiences in daily life and found that emotion-regulation strategies like distraction, cognitive reappraisal, rumination and expressive suppression were associated with emotional carryover, especially after negative events. The study acknowledges that these strategies are not the only factors contributing to emotional inertia. Other factors may be at play as well. It still adds further evidence for the idea of an emotional hangover (Bagnara et al., 2025).
Looking at this research together, the findings suggest that the experience described as an emotional hangover may involve several underlying psychological processes. Emotional experiences can influence what we remember. Stress can persist after the stressor ends. Emotional states can persist beyond the event that caused them. Processes such as rumination can help keep the event’s emotions lingering. However, none of these findings establishes the concept of emotional hangover as a distinct psychological construct. Further, is an emotional hangover only possible in the case of negative emotions or also after a positive event?
Positive Emotional Hangover
Emotional arousal refers to how strongly an emotion activates the mind and body, and it can be due to a positive or negative experience or event. This shows that positive experiences can be emotionally intense too. A concert, a wedding, a celebration or a reunion can involve excitement, anticipation and a heightened emotional arousal, followed by a sense of tiredness or emotional depletion once the experience is over. However, much of the research discussed here focuses on stress, negative affect and emotional persistence, so the psychological process behind the aftermath of positive emotional experiences remains less clear.
How To Deal With An Emotional Hangover?
Because an emotional hangover involves complex processes, recovery may require more than simply trying to “move on”. Below are some ways to recover from an emotional hangover.
1. Give It Time
Probably the most basic thing you can do when experiencing an emotional hangover is to give yourself time to return to baseline. Do not force yourself to immediately move on. You may not be able to take a day off from your responsibilities. But you can give yourself mental space to acknowledge and process what happened. Processing an experience, however, does not mean ruminating on it and repeatedly going over it. Excessive rumination can keep negative emotions lingering.
2. Good Sleep And Rest
Sleep plays an important role in emotion regulation and processing (Tempesta et al., 2018). Getting enough rest may therefore be particularly helpful after an emotionally demanding experience or event.
3. Reach Out To A Friend
Social connection can also be incredibly helpful in moments like this. Talking to a trusted friend or family member gives you an opportunity to express what you are feeling. It can also help you feel less alone while processing the experience. If you don’t feel like talking about it, simply reach out. Let a friend, family member or colleague you trust know that you have a lot on your plate and feel drained right now. This can help lessen the pressure to move on quickly.
4. Mindfulness and journaling
Practising mindfulness, like meditation, yoga, or journaling about your feelings, can help you reflect on your thoughts and feelings. It can also be a way of creating space to process an experience rather than immediately pushing it away.
Conclusion
Coming back to the main question, is an emotional hangover a fact or a metaphor? Perhaps it is both.“Emotional hangover” is not a formally recognised or studied psychological construct. But the experience it describes may reflect several well-documented processes. These include emotional persistence, memory consolidation and the effects of emotion-regulation strategies like rumination, distraction, cognitive reappraisal and expressive suppression. It also overlaps with the concept of emotional inertia.
Perhaps, then, we do not need to discard the term simply because it is not a psychological phenomenon. Instead, we can learn to manage the feeling when it comes up. We can also accept that emotional hangover may be an everyday metaphor for something much more complex. It is the way an emotionally significant experience, negative or positive, can continue to echo through our memories, thoughts, feelings and body. It can do so even after the moment has passed. And perhaps, it serves another important purpose: a reminder of the beauty and complexity of the human brain.
