Alcohol and aggression

Why does alcohol often lead to fights, arguments, and aggression?

Drinking alcohol can make us act in ways we wouldn’t normally, including being angry or aggressive.

Experts believe the reason some people become aggressive when drunk is due to the way alcohol affects the brain.¹

Binge drinking (more than six units of alcohol in a single session for women and eight units for men)² increases the likelihood of someone becoming aggressive or angry, and also being on the receiving end of someone else's temper.³

Why do some people become angry when they drink alcohol?

The impact of drinking alcohol on aggressive or violent behaviour is complex.⁴

Many people who drink are never violent and even those who do become aggressive won't do so all the time. But there is strong evidence of a link between alcohol and aggression.

There are several ways that alcohol affects our bodies that can contribute to aggression.^5,6

Alcohol can narrow your attention and stop you seeing the big picture
You may miss social and environmental cues that help you to interpret situations rationally (known as ‘alcohol myopia’), and give less attention to the wider consequences of immediate actions.^7,8 This means someone who’s been drinking might ‘rise to the bait’ rather than thinking of the consequences, and become angry or violent – even over something they would normally shrug off.
The way you process information is affected by drinking alcohol
After drinking alcohol, you are more likely to misinterpret other people's behaviour.⁹ This could be the reason why drunken fights can start over little more than bumping into someone at a bar.
Alcohol suppresses inhibition, making it harder to think straight
Drinking affects your brain chemistry. Small amounts of alcohol can cause initial feelings of relaxation, but what’s actually happening is that alcohol is suppressing activity in parts of the brain associated with inhibition.¹⁰ Any warning signals that may normally kick in (‘inhibition’) are less likely to work, and you may be more likely to find yourself in confrontational or even dangerous situations. The more you drink the higher the chance it can cause feelings of tension and anxiety because of effects on brain chemicals including GABA. GABA is a chemical in the brain that normally has a relaxing effect but heavy drinking can deplete GABA, causing increased tension and feelings of panic.^11,12

Tools to reduce your drinking

The impact of alcohol-related violence

There were 440,000 incidents of violent crime in England and Wales in 2023/24 where the victim believed the offender was under the influence of alcohol.¹³

Partner violence

Studies also show that there is a clear link between alcohol use and intimate partner violence – which is any form or physical, sexual or psychological violence against a current or former partner.^{14,15,16,17,18}

Nearly a quarter (24%) of domestic violence victims believed the offender to be under the influence of alcohol or drugs.¹⁹

Women are at a higher risk of harm against them by a male partner who has been drinking than vice versa.^20,21

Just over a quarter (26%) of perpetrators of domestic homicide incidents in the UK had alcohol misuse problems.²²

Children

Others can be affected by alcohol-related violence too, including wider family and friends as well as children.

It is estimated that between 2019 and 2020, there were 478,000 children living with an alcohol or drug dependent parent.²³

According to The Children’s Society, 39% of children living with a parent or carer with problematic alcohol use were in a household where there had been domestic violence in the last five years. These children are almost three times more likely to be in a home affected by domestic violence than those who aren’t exposed to problem drinking by a parent or carer.²⁴

Parental substance misuse (alcohol or drugs) was recorded in 39% of serious case reviews between 2014 and 2017, which are carried out when a child has died or has been seriously harmed.²⁵

If you have been the victim of violent or aggressive behaviour, report it to the police. Call 999 if anyone is in immediate danger, 101 if it's not an emergency, or you can report crime to the police online.

Cutting back on alcohol to manage anger

Cutting down on the amount you drink can help you stay in control. And cutting down or stopping has lots of other benefits too, for your physical and mental health. Try these tips to get started.

Stick to the UK low risk drinking guidelines

If you decide to drink, the UK Chief Medical Officers’ (CMOs) low risk drinking guidelines advise it’s safest for both men and women to drink no more than 14 units a week, spread evenly over three or more days with several drink-free days.²⁶

Take the Drinking Check

Never binge drink

As well as being linked to aggression (and making it more likely you could be on the receiving end), binge drinking harms your physical and mental health. One way to have a bit less is to alternate alcoholic drinks with a soft drink or water.

How much is a ‘binge’?

Have plenty of drink-free days

There's lots of ways to enjoy more drink-free days – from easy activities to get in shape to simple tips to help you stay on track when temptation strikes. And we’ve got the advice that can help you get started.

Ideas for drink-free days

Cut down together with your partner or friends

Even if you don’t find drinking makes you aggressive, you might find drinking sometimes leads to an argument. So, why not cut down together and enjoy all the benefits that it can bring.
