Does venting anger help? The evidence says calming down works better
Across 154 studies, activities that lower arousal — slow breathing, meditation — reduced anger and aggression. Venting-style activities that raise it, like hitting a bag or going for a run, did not.
| Group | Value (value) |
|---|---|
| Arousal-decreasing (breathing, meditation) | 0.63 (0.43 to 0.82) |
| Arousal-increasing (hitting a bag, jogging) | 0.02 |
Venting anger — hitting something, shouting, or working up a sweat to "blow off steam" — does not reliably reduce it, and can keep it going [s1][s2]. A 2024 review of 154 studies found that activities which lower the body's arousal, such as slow breathing and meditation, cut anger and aggression, while activities that raise arousal did essentially nothing [s1].
This article describes published psychological research. It is not medical or psychological advice. If anger is putting you or others at risk, a clinician or a helpline is the right first step.
What the big review tested
The most complete synthesis is a 2024 meta-analysis in Clinical Psychology Review that pooled 154 studies — 184 independent samples and 10,189 participants in total — comparing two kinds of anger-management activity [s1]. One kind is designed to bring arousal down: deep breathing, mindfulness, meditation, relaxation. The other brings arousal up: hitting a punching bag, jogging, cycling, and other vigorous outlets that the popular "let it out" model assumes will discharge the anger [s1].
The results were lopsided. Arousal-decreasing activities produced a moderate, reliable reduction in anger and aggression, with an effect size of g = -0.63 (95% confidence interval -0.82 to -0.43) [s1]. Arousal-increasing activities produced an effect of g = -0.02 (95% CI -0.13 to 0.09) — statistically indistinguishable from doing nothing [s1].
The calming effect was also robust. It held across genders, races, ages and cultures; in students and non-students; in criminal offenders and non-offenders; and whether delivered by a therapist, a researcher or a digital app, in groups or one to one [s1]. The authors' plain-language conclusion was that "turning down the heat" beats "letting off steam" [s1].
Why "getting it out" fails
The idea that venting drains anger is catharsis theory, and it has been failing controlled tests for a long time. In a 2002 experiment, angered participants who hit a punching bag while thinking about the person who had provoked them — the textbook venting scenario — went on to feel angrier and behave more aggressively than participants who had been distracted, and more than a control group that did nothing at all [s2]. Rumination, even with a physical outlet attached, fed the anger rather than extinguishing it [s2]. The blunt finding was that doing nothing was more effective than venting [s2].
That is the mechanism behind the meta-analysis. The problem is not the punching bag itself but the state it maintains: a racing heart and a mind still fixed on the grievance. Vigorous exercise can be good for mood in general, but as an in-the-moment anger cure it keeps arousal high, which is exactly the wrong direction [s1].
It is worth being precise about what the review does and does not say. It is not a claim that expressing feelings is harmful, or that anger should be bottled up. It is a narrower, better-tested point: activities chosen specifically to discharge anger through physical intensity do not lower it, whereas activities that slow the body down do [s1]. The distinction the evidence draws is between arousal and expression, not between action and suppression [s1][s2].
What the evidence points to instead
The activities that worked share one feature — they lower physiological arousal [s1]. That places the anger findings alongside the rest of this site's coverage of low-cost, self-directed practices: the evidence for breathing exercises and for mindfulness apps points the same way, and a network meta-analysis of wellbeing interventions makes the general case that small, calming habits add up. None of this makes anger a problem to solve alone when it is severe or dangerous.
What to take from it
The honest summary is that the cultural advice to vent is backwards: on the current evidence, calming the body down reduces anger, and stoking it up does not [s1][s2]. That does not mean suppress or ignore the feeling — it means the reliable tools are the boring ones, breath and stillness, not the dramatic ones.

Repeating 'I'm a lovable person' left people with low self-esteem feeling worse in controlled experiments. A different technique — writing about your core values — has stronger evidence behind it.
Does a gratitude practice work? Small, real, and oversold
A gratitude habit gives most people a genuine but small lift in wellbeing — a 2025 meta-analysis of nearly 25,000 people put the average effect at a modest 0.19 — and its unique benefits are probably overstated.

Dopamine is a learning signal that tracks surprise, not a pleasure tank you drain and refill. Stripped of the neuroscience label, the practice is ordinary stimulus control — and that narrower version has some support.

The best evidence frames procrastination as a way of dodging bad feelings about a task, not a scheduling flaw — and following students over a year, more of it tracked with more depression, anxiety and stress.
