Alcohol and Anxiety: What's the Connection?

Alcohol and Anxiety

Introduction

Anxiety is a common mental health issue affecting millions of people worldwide. It's characterised by feelings of worry, nervousness, or unease about things that might happen in the future. Alcohol, on the other hand, is often used socially and recreationally, but it can have a significant impact on our mental health, particularly on anxiety.

A double-edged sword

Alcohol is a depressant; and whilst drinking may temporarily relieve anxiety or ease social interactions, its prolonged use can worsen underlying anxiety symptoms and disorders. It can mask short-term problems, whilst potentially creating a cycle of dependency and worsening mental health in the longer term.

A temporary ‘calm’

Alcohol can initially induce a sense of relaxation and reduce anxiety. It influences neurotransmitters like serotonin and GABA which play a crucial role in mood regulation. It can slow down the body’s systems, temporarily elevating mood and a sense of calm. Temporary relief provided by alcohol may seem appealing to individual’s dealing with distressing emotions and experiences in the short-term, but symptoms of mental health can be exacerbated long-term.

The Rebound Effect: how alcohol worsens anxiety

The initial calming effects of alcohol can create an illusion of control over an individual’s own emotional state. The relief is temporary and often followed by a rebound effect. This is a significant issue for people who use alcohol to manage their anxiety and depression as symptoms may intensify.

The increase in anxiety can be attributed to several factors, including the body’s physiological response to alcohol withdrawal and the psychological stress associated with the potential negative consequences of the previous night’s drinking.

After the initial calming effect wears off, the brain can experience heightened levels of anxiety. This is because the body has to work hard to restore its normal balance, and during this period, anxiety levels can spike. This can lead to a vicious cycle. You drink to reduce anxiety, but once the alcohol wears off, you feel even more anxious than before. This can lead to drinking more alcohol to manage the increased anxiety, which only perpetuates the cycle.

Hangxiety: hangover plus anxiety

Alcohol can trigger or exacerbate panic attacks in susceptible individuals. This is due to the physiological changes that alcohol induces in the body, such as an increased heart rate, a drop in blood sugar, and eventual dehydration.

Alcohol-induced hangovers are widely reported to intensify anxiety symptoms, also referred to as ‘hangxiety’. This is likely linked to the body’s physiological stress responses, including alterations in neurotransmitter levels and increased cortisol production, which can mimic anxiety symptoms.

Self-medication & dependence

Alcohol is often used as a form of self-medication, providing temporary relief from stress, anxiety, and other mental health issues. The self-medication concept shows that some individuals maybe more susceptible to developing problematic drinking behaviours due to a tendency to use alcohol as a coping mechanism for negative emotions like anxiety, or Post-Traumatic Stress Disorder (PTSD).

Research shows that one influence for alcohol consumption is the temporary relief it provides from emotional discomfort. However, this form of self-medication can lead to a vicious cycle, where the initial alleviation of symptoms is followed by the rebound effect, often exacerbating the very symptoms individuals are trying to mitigate.

Over time, this pattern can escalate into alcohol dependence, further complicating the individual's mental health. This dependence on alcohol can also lead to physical health problems as well as exacerbating mental health issues. It's crucial to understand that while alcohol may seem like a solution in the short term, it often contributes to the very problems it's used to escape from in the long run.

Nutritional Impacts of drinking

Research indicates that both acute and chronic alcohol consumption can cause malnutrition by decreasing long-term dietary caloric intake, impairing nutrient digestion and absorption, decreasing protein synthesis and secretion, and increasing breakdown and excretion of nutrients.

Nutrients like folate, B12, vitamin D, selenium, calcium, iron, zinc, and omega-3 are associated with adverse effects on mental health. These nutrients are essential for the production of neurotransmitters like serotonin, dopamine, and norepinephrine, which regulate mood, appetite, and cognition.  

Heavy alcohol consumption depletes numerous nutrients essential for optimal brain function, including the B vitamins thiamine, folate, B6 and B12. A diet lacking in these key nutrients can lead to a higher risk of developing mental health disorders and other complications such as Wernicke-Korsakoff syndrome. However, the degree of malnutrition depends on the amount of alcohol consumed.

How can nutrition help?

Alcohol can disrupt the balance of gut bacteria and interfere with the body’s ability to absorb and utilise essential nutrients, leading to malnutrition even when caloric intake is adequate. This is particularly true for vitamins and minerals that are crucial for brain function and mental health.

Adherence to healthy dietary patterns, such as the Mediterranean diet, which is rich in fruits, vegetables, nuts, and legumes or the ketogenic diet, high in essential fats, have been linked to better mental health outcomes compared to diets high in processed foods and sugars.

Supplementation can be a useful strategy to replenish these nutrients and support brain health. For instance, B-vitamins are crucial for the functioning of the nervous system and cognitive processes. Magnesium plays a role in nerve transmission and the prevention of neuroinflammation. Zinc is essential for neurotransmission and brain development. Omega-3 plays a crucial role in reducing inflammation and protection against oxidative stress.

Individuals who consume alcohol regularly may benefit from a nutrient-rich diet and potentially, targeted supplementation, to address these deficiencies. While improving nutrition can support overall health, it does not counteract all the negative effects of alcohol. Limiting alcohol consumption where possible remains the important factor.

Conclusion

The relationship between alcohol and anxiety is complex. While alcohol might provide temporary relief from anxiety, it ultimately exacerbates the problem. Understanding this relationship is the first step towards making healthier choices that can lead to better mental health.

It's important to remember that if you or someone you know is struggling with anxiety and alcohol use, help is available. Seeking support from qualified healthcare professionals can make a significant difference and lead to healthier, more sustainable ways to manage anxiety.
