A study says taking a deep breath before an angry reply may help but there’s a catch to the advice

Someone sends you a rude message. You read it twice. Your jaw tightens, and your fingers move towards the keyboard. A sharp reply feels justified. Waiting feels almost impossible.

Slow, comfortable breathing may help reduce anger and create space before you respond. Research supports calming the body although saying a few deep breaths automatically make people rational would stretch the evidence.

What does research say about breathing and anger?

Psychologists Sophie Kjærvik and Brad Bushman examined anger-management activities in a 2024 review published in Clinical Psychology Review.


Their meta-analysis combined findings from 154 studies involving 10,189 participants. A meta-analysis brings results together to identify patterns across research.

Activities that lowered physiological arousal, including breathing exercises and relaxation, reduced anger and aggression overall. Activities that increased arousal did not help overall.

Arousal means how physically activated you feel. A racing heart and tense muscles are familiar signs. The review supports calming strategies. It did not isolate breathing as the only effective ingredient or establish that every technique works equally well.

Why might slower breathing calm the body?

Breathing interacts with the autonomic nervous system, which helps regulate functions such as heart rate. Its parasympathetic branch supports bodily regulation and recovery. Researchers study how deliberate breathing influences that system.

A 2018 systematic review led by Andrea Zaccaro examined slow breathing in healthy people. It identified changes in heart-rate variability alongside reports of greater relaxation and reduced arousal.

Heart-rate variability describes variation in the time between heartbeats. Breathing itself changes that pattern, so a higher reading during an exercise cannot automatically prove improved emotional control.

The findings suggest links between breathing and emotional regulation. The review also highlighted differences between studies and gaps in understanding the mechanisms.

Can slow breathing help you think more clearly?

An experiment led by psychologist Sylvain Laborde offers a relevant clue. Seventy-eight participants completed a slow-breathing condition and a television-viewing condition. The breathing condition involved three five-minute periods.

Afterwards, participants performed tasks testing executive functions. These are mental skills that help us manage attention and control responses. Performance improved on several measures after slow breathing. One involved inhibition, or resisting an automatic response.

Imagine wanting to interrupt someone during an argument. Inhibition helps you hold back long enough to hear their answer.

However, laboratory task performance differs from making a sensible decision during a real disagreement. The experiment did not prove that a few breaths make angry people rational. The proposed explanation involving cardiac vagal activity also did not account for the performance changes.

How can cognitive reappraisal change an angry response?

Breathing can be paired with reconsidering your interpretation of events. Psychologist James Gross studied cognitive reappraisal, which means changing how you understand a situation to influence your emotional response.

In a 1998 experiment participants watched an upsetting film. Reinterpreting it reduced their negative emotional experience. Hiding outward emotion had different effects, including increased sympathetic activation.

The study looked at people watching an upsetting film. It did not test breathing during arguments. The findings suggest that looking at a situation differently can change how you feel. Hiding your feelings may not have the same effect.

Consider a colleague’s brief reply: “Do it again.” Your first interpretation might be, “They are insulting me.” Another possibility is that they are rushed or communicating poorly.

Reappraisal means considering those possibilities before treating one explanation as fact. Asking what needs changing may be more useful than answering an insult you have assumed.

How should you breathe when you feel angry?

Aim for gentle and comfortable breathing. Taking the biggest possible breath is unnecessary. NHS guidance recommends letting the breath move towards the belly without forcing it. Breathe gently through the nose and out through the mouth.

A comfortable count can help establish a steady rhythm. The guidance suggests counting towards five on each breath, adjusting the count to what feels manageable.

The NHS recommends practising for at least five minutes. A short pause may interrupt an immediate reply but research does not establish a universal number of breaths that switches anger off.
