Toxic Positivity: Why Does Forced Cheerfulness Backfire?
Hiding a feeling behind a smile does not remove it. A review of current PubMed evidence on toxic positivity, acceptance, and what suppression does to desire.
Most people who say “I’m fine, just tired” are telling the truth about the tiredness. The smile that comes with it has been rehearsed for years, and its job is to end the conversation early. One question: when a feeling is hidden behind a smile, where does it go?
Because suppression switches off the outward expression of an emotion, not the emotion. The body stays aroused, the mind stays occupied, and a new load sits on top: holding the mask in place. Psychology calls this expressive suppression, and it is not the same as regulating an emotion well.
The largest picture we have is a meta-analysis published in Nature Human Behaviour in April 2025: 249 articles, 150,474 participants, 861 effect sizes, across 37 countries. Its central finding is not that suppression is equally damaging everywhere — the opposite. It shows that culture sets the size of the cost: suppression was more maladaptive in more indulgent, more competition-driven cultures, and in younger samples.
For an Iranian professional in Toronto or Los Angeles that means you are suppressing inside a context where suppression is priced higher. The limitation, plainly: these data are correlational, not causal, and rest almost entirely on self-report.
Psychoanalysis reached a version of this a century earlier. Freud called it Verdrängung: what is pushed out of awareness is not destroyed but returns elsewhere — in insomnia, in disproportionate anger over something trivial, in a desire that quietly goes missing. The twenty-first century added the numbers.

What Is Acceptance, and How Is It Different From Resignation?
Acceptance means not judging what is happening inside you: instead of “I shouldn’t feel this,” it is “right now, I feel this.” That is not the same as accepting your circumstances — which is where most people get it wrong.
Ford and colleagues tested this across three studies in the Journal of Personality and Social Psychology (2018): 1,003 people, a laboratory study with 156, and a six-month follow-up with 222. Those who habitually accepted their mental experience without judging it felt less negative emotion during everyday stressors and reported better psychological health six months later.
The sharp point: the benefit appeared only for accepting mental experience, not the situation. “I accept my anger” works; “I accept this unacceptable arrangement” does not. Someone in a disrespectful relationship is not asked to accept the relationship — only the anger, and then to decide with it.
In consulting rooms this misunderstanding shows up constantly. A client hears “acceptance”, assumes they must put up with something, and resists — rightly. Once it is clear nobody is asking them to accept the situation, only to name what they feel, the resistance usually collapses in the same session. Limits: predominantly US samples, self-report.
Why Doesn’t Saying “I’m Fine” in a Second Language Calm You Down?
Because the brain treats naming an emotion as regulation only when the word carries real emotional weight — and for most immigrants, the second-language word does not.
The foundation is a classic experiment by Lieberman and colleagues in Psychological Science (2007): when a person converts a feeling into words, amygdala activity — the brain’s alarm centre — falls while the right ventrolateral prefrontal cortex becomes more active. Naming a feeling is a measurable neural operation, not just good advice.
Now the part that matters for the diaspora. Vives and colleagues, in Affective Science (2021), ran the same paradigm with 26 unbalanced bilinguals — people fluent in a second language that is not their mother tongue. The result inverted: labeling an emotion in the foreign language did not quiet the amygdala at all, but produced higher activation than the native language.
The clinical translation: if you spend your day in English in Toronto, Vancouver or Los Angeles and then tell yourself “I’m fine” in English at night, you may be doing two things at once — suppressing, and losing the one tool that could have replaced it. For many clients a sentence in the mother tongue does work its English equivalent does not. [Needs further verification: this study had only 26 participants and has not been replicated at scale; generalising it to all bilinguals would be premature.]

What Does Emotional Silence Do in the Bedroom?
It damages sexual communication, and that damage has been measured. In the Journal of Sex Research (2023), 64 couples in which the man had distressing low sexual desire were assessed. The more he suppressed his feelings about their sexual relationship, the lower his assertiveness — and both partners reported poorer sexual communication. Suppression does not only hurt the person doing it; it silences the room.
Both sides of the scale belong here, or the picture becomes biased. Weckbacher and Baker, in the Journal of Family Psychology (2018), found something in newlywed couples that is uncomfortable but real: people whose partner was unsupportive or showed depressive symptoms stayed more satisfied when they suppressed, because they attributed the missing support to “he didn’t know” rather than to indifference. People with supportive partners grew less satisfied the more they suppressed.
The main finding, without hedging: suppression is an insurance policy, not a solution. In a relationship that does not answer you, it protects you from disappointment. In one that does, it prevents the answer. The question is knowing which one you are in. Limits of both studies: small, largely Western samples, self-report.
What is the difference between healthy optimism and toxic positivity?
Healthy optimism arrives after a feeling has been named: “I was frightened, and now I am looking for a way through.” Toxic positivity takes its place: “Don’t be frightened.” The first adds options; the second removes them.
If I show what I feel, won’t I hurt the people around me?
Expressing an emotion is not discharging it onto someone. “I’m angry and I need twenty minutes alone” is expression; shouting is discharge. The research supports naming, not throwing.
Why is it easier to talk about feelings in my mother tongue?
Brain imaging suggests naming an emotion in your native language lowers the brain’s alarm response, while doing the same in a second language may have the opposite effect. For immigrants, therapy in the mother tongue may be more effective, not merely more comfortable.
Does emotional suppression affect sexual desire?
Yes, mainly through communication. Where one partner hides how they feel about sex, both report poorer sexual communication and assertiveness drops. Silence is itself a message, usually the wrong one.
Feeling Well Is a Product of Honesty, Not of Smiling
None of this evidence says optimism is bad. It says durable optimism grows out of a feeling being seen rather than routed around. The smallest practical step may be this: tonight, instead of “I’m fine,” find a more accurate sentence — and if you have a mother tongue, find it there. As far as the brain is concerned, the two are not the same thing.
