Does Venting Anger Help, or Make It Worse?

Somebody has just humiliated you in a meeting. A friend's advice is simple: go to the gym and hit something, scream in the car, get it out of your system. It feels right. Anger seems like pressure, and pressure needs a release valve.

The research on this is unusually consistent, and it says the opposite. Letting anger out by acting it out tends to keep it going. What actually brings it down is much less dramatic.

Where the steam idea comes from

The word catharsis comes from the Greek for cleansing or purging, and the idea behind it is intuitive: emotions build up like steam in a boiler, and unless you release them they will burst out somewhere else. This image runs through popular psychology, self-help books and advice columns, and it is why rage rooms and punching pillows are marketed as healthy.

It is also a testable claim. If venting releases pressure, people who vent should end up calmer and less aggressive than people who do not. Psychologists have been running that test for decades.

The punching bag experiment

The best-known version was published in 2002 by the social psychologist Brad Bushman in Personality and Social Psychology Bulletin. Participants were first deliberately angered in the laboratory. Then they were split into three groups.

• The rumination group hit a punching bag while thinking about the person who had angered them - classic venting.
• The distraction group hit the same punching bag while thinking about becoming physically fit.
• The control group did not hit anything; they simply sat for a while.

Afterwards everyone reported how angry they felt, and then got a chance to blast the person who had provoked them with loud noise through headphones - a standard laboratory measure of aggression.

The results were the reverse of what catharsis predicts. The rumination group felt the angriest. They were also the most aggressive, followed by the distraction group, with the control group least aggressive of all. In Bushman's words, doing nothing at all was more effective than venting anger.

It is worth being honest about the limits. This was one laboratory study with university students, the provocation was mild compared with real life, and noise blasts are a stand-in for aggression, not the real thing. On its own it would be interesting rather than conclusive. What makes it important is that it fits a much larger body of evidence.

154 studies later

In 2024 Sophie Kjærvik and Bushman published a meta-analysis in Clinical Psychology Review that pulled together 154 studies, with 184 independent samples and 10,189 participants. They sorted anger management activities into two kinds: those that raise physiological arousal, such as hitting a bag, jogging or cycling, and those that lower it, such as slow breathing, mindfulness, meditation or relaxation.

The difference was stark. Arousal-decreasing activities reduced anger and aggression with a moderate-to-large effect, and the result held across genders, ages, cultures, students and non-students, offenders and non-offenders, and in both laboratory and field settings. Arousal-increasing activities, taken together, had essentially no effect.

Two nuances are worth keeping. First, the review does not say exercise is bad for you; running has plenty of other benefits. It says that using a burst of physical intensity as an anger outlet does not, on average, reduce anger. Second, the arousal-increasing studies were mixed and complex, so the safest summary is "not reliably helpful" rather than "always harmful". The authors' own conclusion is that the evidence does not support venting anger or going for a run as effective anger management.

What works instead

If shouting it out does not help, the obvious alternative is to swallow it. That is not what the research recommends either.

The psychologist James Gross, in an influential 1998 review, described emotion regulation as a process with several points where you can intervene: choosing or changing the situation, shifting your attention, changing how you interpret what happened, and finally changing how you respond. In later work with Oliver John, Gross compared two common strategies. People who habitually reappraise - reinterpret a situation so it means something different - reported more positive and less negative emotion, better relationships and higher well-being. People who habitually suppress - hide the feeling while it continues inside - showed the opposite pattern. Those findings are correlational, so they show what goes together rather than proving cause, but they point in a clear direction.

An experiment on anger specifically comes from Thomas Denson, Michelle Moulds and Jessica Grisham, published in 2012. They had 121 undergraduates recall an event that had made them angry and then spend 20 minutes either analysing it over and over, reappraising it, distracting themselves, or simply writing their thoughts. Rumination kept the anger going. In all the other conditions, anger decreased. The authors suggest distraction gives quick relief, while reappraisal helps you actually process what happened.

Notice what the effective strategies have in common. They do not pretend the anger is not there, and they do not rehearse it. They let the body calm down and give the mind a different frame.

What this means for you

None of this means anger is bad. It is often a useful signal that something is unfair or needs to change. The question is only what to do with the surge itself. Based on the evidence:

• Turn the heat down first. Slow breathing, a quiet walk, a few minutes away from the trigger. The meta-analysis suggests that lowering arousal is the most reliable first step.
• Be wary of replaying it. Going over the insult again and again, in your head or out loud, is the ingredient that kept anger alive in these studies.
• Then reframe, and act if needed. Once calmer, ask what else might explain what happened, and whether there is something concrete to address. Talking it through with someone can help when it moves you towards understanding or a solution, rather than just re-living the scene.

If you want to see your own patterns, our anger style test looks at how anger tends to show up for you, our emotion regulation test asks which strategies you reach for, and our coping style test looks at how you handle stress more broadly. And if anger regularly feels out of control or is hurting you or people around you, that is a good reason to talk to a psychologist; there are well-studied approaches that help.
