Alcohol Suicide & Mental Health

Alcohol can contribute to the development of mental health problems as well as exacerbating pre-existing mental health difficulties

Alcohol can affect our ability to cope, manage and overcome everyday stresses and significant life events such as unemployment or bereavement.

Alcohol can contribute to the development of mental health problems as well as exacerbating pre-existing mental health difficulties.

It can also reduce inhibitions enough for an individual to act on suicidal thoughts which they might never have done if not under the influence of alcohol. Suicide is the leading cause of death among young Irish men aged 15-24. In 2011, 525 suicides were registered, an increase of 7% – 439 of those who died were men.[i]

There exists a consistent trend for drunkenness when drinking among Irish young people, a trend that sets them apart from the majority of their European counterparts.[ii] And children and young people are particularly vulnerable to alcohol-related harms and risks due to the fact that their brains and bodies are still growing and developing:

  • Biologically teenagers’ brains are still developing – alcohol particularly effects the areas of the brain responsible for memory and impulse control
  • Adolescence can be a challenging time as young people navigate new experiences and stresses for the first time: alcohol is being added to situations where there is no pre-existing “road map” and may render the individual particularly vulnerable to exploitation or danger
  • Behaviour patterns that can last a life time are being established during this formative period. Adult heavy drinkers generally established their drinking patterns in their teens

Many people drink alcohol to help them cope with emotions or situations they would otherwise find difficult to manage. In other words, they drink to change mood or mental state. Alcohol is also used to self-medicate, to relieve the symptoms of anxiety and depression. In the UK, a country with similar drinking patterns to Ireland, a study found that stressed mood leads to increased alcohol consumption. [iii] Relaxation was also a key reason cited for people drinking.

Tolerance of alcohol increases with use, so that an individual needs increasing amounts of alcohol to decrease their anxiety or to medicate their depression. Secondly, when self-medicating with alcohol it is difficult to know how much is enough. Following the initial feeling of well-being from the first drink, alcohol acts as a depressant, and feelings of anxiety and depression can quickly resurface. Indeed, alcohol use can exaggerate underlying feelings, which is why some people become angry, tearful, or aggressive after a few drinks.

Although many factors are involved in suicide, the link between alcohol use and suicide has been well established, alcohol consumption considered to be a significant influence on the suicide rate of young men in particular.[v] Suicide is the leading cause of death among young Irish men aged 15-24 years with more than one in three deaths in that age group as a result of suicide.

A national study of youth mental health found strong links between excessive drinking and suicidal behaviour. The same study provided clear evidence that excessive drinking is associated with poor mental health and low self-esteem.[vi]

The connection between alcohol use and suicide has been highlighted in numerous reports, both Irish and international. One Irish study of people from three counties who died as a result of suicide, found that more than half had alcohol in their blood; those aged less than 30 were more likely to have had alcohol in their blood at the time of death.[vii]

The World Health Organisation has estimated that the risk of suicide when a person is currently abusing alcohol is eight times greater than if they were not abusing alcohol. [viii] Closer to home, a report from the UK Mental Health Foundation states that as many as 65% of suicides were related to excessive drinking, and identifies alcohol problems as one of the highest risk factors for suicide. [ix] That report identifies a strong link between alcohol use and thoughts of suicide, suicide attempts and completed suicides among young people under the age of 24. Alcohol use can act as a factor in suicidex in a number of ways:

  • A HSE reportxi tells us that “alcohol can facilitate suicide by increasing impulsivity, changing mood and deepening depression
  • Self-harm or suicide can take place after just one drinking session. A person doesn’t have to be a heavy drinker or even a regular drinker: just one occasion of heavy drinking can reduce inhibitions enough to self-harm  or act on suicidal thoughts
  • Alcohol initially produces feelings of happiness and well-being but can lead to a significant lowering in mood hours after use or in the following days, an experience which is sometimes accompanied by feelings of hopelessness. If someone is already experiencing a degree of depression, the fall in mood can lead to suicidal ideasxii
  • Ongoing abuse of alcohol is itself a major contributory factor in depression and suicidal behaviourxiii
