Alcohol can cause panic attacks the next day due to its effect on the brain's chemical balance. Alcohol affects the release of gamma-aminobutyric acid (GABA), a neurotransmitter that normally helps the body relax and feel calm. While small amounts of alcohol can stimulate GABA, heavy drinking can deplete it, leading to increased tension and feelings of panic. Additionally, as alcohol is a diuretic, it can cause dehydration, which may result in a faster heart rate and dizziness, further triggering anxiety. The risk of alcohol-induced panic attacks is higher for those with pre-existing anxiety disorders or a history of alcohol dependence.

What You'll Learn
Alcohol's effect on GABA
Alcohol can cause panic attacks, even the next day, due to its effects on the brain's chemistry. One of the chemicals affected is gamma-aminobutyric acid, or GABA, which is a primary inhibitory neurotransmitter in the mammalian central nervous system (CNS).
GABA is responsible for regulating many physiological processes, including anxiety, sleep, and the overall excitability of the nervous system. It also plays a role in the generation of brain waves that aid with relaxation and certain states of consciousness. When stimulated, GABA helps the body and brain relax and promotes feelings of calm and tiredness. It does this by preventing excitatory neurotransmitters like dopamine and noradrenaline from overstimulating the brain, slowing down heart rate and breathing, and relaxing muscles.
Alcohol does not bind directly to GABA receptors. Instead, it binds to specific allosteric sites on GABA-A receptors, enhancing the inhibitory effects of GABA. Small amounts of alcohol can stimulate GABA and cause feelings of relaxation. However, chronic alcohol exposure ultimately disrupts and depletes essential inhibitory signalling in the brain. The more you drink, the less your brain is capable of producing GABA. This can lead to a state of hyperexcitability in the brain, which can cause panic attacks.
Additionally, when subjected to frequent binge episodes, the brain compensates for the acute depressant effects of alcohol by down-regulating GABAA-mediated inhibitory signalling and upregulating excitatory glutamatergic function. This results in further hyperexcitability, which becomes apparent upon cessation of prolonged alcohol misuse in alcohol use disorder (AUD), reflected in withdrawal symptoms including insomnia, irritability, anxiety, autonomic hyperactivity, and even seizures.
The risk of alcohol-induced panic attacks is higher for those with pre-existing anxiety disorders or a history of panic attacks. It is important to note that alcohol dependence can develop over time, and the negative side effects of chronic alcohol use can outweigh the temporary feelings of calm and relaxation.

Alcohol withdrawal
The brain, which has become accustomed to the depressant effects of alcohol, overcompensates by producing stimulating chemicals in higher-than-normal amounts. When alcohol is suddenly removed, the brain becomes overstimulated, leading to withdrawal symptoms, including panic attacks. Attempting to detox from alcohol without professional supervision can be dangerous, especially for those at risk of severe withdrawal symptoms. Alcohol withdrawal can be life-threatening, particularly for individuals with a history of long-term alcohol use.
The process of detoxing from alcohol can trigger a range of withdrawal symptoms, including panic attacks. Research has shown that those who attempt to withdraw from alcohol often meet the diagnostic criteria for panic attacks, panic disorder, and even agoraphobia. This anxiety disorder is characterized by a fear of being in situations where escape might be difficult or finding oneself in places or situations that might cause panic and feelings of being trapped, helplessness, or embarrassment.
Alcohol has an effect on many chemicals in the brain, including GABA, serotonin, and dopamine. When these brain chemicals are altered, it can disrupt how the body reacts in everyday situations. Alcohol can induce panic because of its effects on GABA, a chemical that normally has a relaxing effect. Small amounts of alcohol can stimulate GABA and cause feelings of relaxation, but heavy drinking can deplete GABA, causing increased tension and feelings of panic. The more you drink, the greater your tolerance for alcohol, meaning you need to drink more to get the same feeling. If you rely on alcohol to mask anxiety, you may find yourself becoming dependent on it to relax, putting you at risk of alcohol dependence.
There are ways to cope with a panic attack, regardless of whether it's caused by alcohol or something else. It is counterproductive to try to fight it or distract yourself. Instead, it can be helpful to try to understand what's happening in your body and help yourself feel more comfortable. One method is the AWARE technique: acknowledging and accepting that the panic attack is happening, recognizing that you are afraid but not in danger, waiting, and observing how you feel. Repeat the steps as needed. Regardless of how you respond, a panic attack will generally end in under 15 minutes.

Alcohol and hypoglycaemia
Alcohol can cause panic attacks, both directly and indirectly. It can induce panic attacks due to its effects on GABA, a brain chemical that normally has a relaxing effect. Small amounts of alcohol can stimulate GABA and cause feelings of relaxation, but heavy drinking can deplete GABA, causing increased tension and feelings of panic. Additionally, the risk of alcohol-induced panic attacks is higher for those with pre-existing anxiety disorders. People with anxiety disorders may self-medicate with alcohol to reduce their anxiety levels, but heavy alcohol use can lead to alcohol dependence, and withdrawal from alcohol can cause severe anxiety.
Now, regarding alcohol and hypoglycaemia, doctors associate alcohol consumption with a higher risk of hypoglycaemia, or low blood sugar. The body requires balanced blood sugar levels to function properly, and the liver is responsible for maintaining these levels. The liver also plays a role in detoxifying the body of alcohol. When an individual consumes alcohol, the liver may prioritise breaking down alcohol over maintaining blood sugar levels, leading to hypoglycaemia. This risk is particularly relevant for people with diabetes, as alcohol can interfere with diabetes medications such as insulin and sulfonylureas, further increasing the likelihood of hypoglycaemia. Additionally, if an individual drinks on an empty stomach or when their blood sugar levels are already low, they are more likely to experience hypoglycaemia. Therefore, it is recommended to eat enough food before and while drinking alcohol to prevent hypoglycaemia.
Furthermore, it is important to note that the symptoms of hypoglycaemia and intoxication can overlap, making it challenging to distinguish between the two conditions. Symptoms such as slurred speech, drowsiness, confusion, and difficulty walking may be indicative of either hypoglycaemia or intoxication. Hypoglycaemia can also occur several hours after drinking, especially if the individual has been exercising. In severe cases of hypoglycaemia, seizures or coma may occur, underscoring the importance of monitoring blood sugar levels and seeking immediate medical attention if necessary.
In summary, alcohol can induce panic attacks directly by affecting brain chemistry, particularly GABA levels. Additionally, it can indirectly increase the risk of panic attacks in individuals with pre-existing anxiety disorders. Regarding hypoglycaemia, alcohol consumption is associated with a higher risk, especially for people with diabetes, as it interferes with the liver's ability to regulate blood sugar levels. The overlap in symptoms between hypoglycaemia and intoxication can make it challenging to differentiate between the two conditions. Therefore, it is crucial to monitor blood sugar levels when consuming alcohol, especially for those with diabetes, and to seek medical attention if severe hypoglycaemia symptoms arise.

Alcohol's effect on serotonin
Alcohol has been found to affect serotonin, a neurotransmitter that acts as a brain chemical to communicate information among nerve cells. Serotonin's actions have been linked to alcohol's effects on the brain and alcohol abuse.
Alcoholics and experimental animals that consume large quantities of alcohol show differences in brain serotonin levels compared to non-alcoholics. Both short- and long-term alcohol exposure affect the serotonin receptors that convert the chemical signal produced by serotonin into functional changes in the signal-receiving cell. Drugs that act on these receptors can alter alcohol consumption in both humans and animals.
Serotonin, along with other neurotransmitters, may contribute to alcohol's intoxicating and rewarding effects. Abnormalities in the brain's serotonin system appear to play a role in the brain processes underlying alcohol abuse. Acute alcohol exposure enhances the electrical signals generated by the 5-HT3 receptor, which is activated by serotonin binding. This change in receptor function likely results from alcohol's direct action on the receptor protein or closely associated molecules.
The increased function of the 5-HT3 receptor leads to excessive stimulation of neurons in brain regions receiving information from serotonergic neurons. Consequently, the release of other neurotransmitters that play key roles in alcohol intoxication may be increased.
In summary, alcohol affects serotonin levels and receptor function in the brain, contributing to its intoxicating effects and potentially leading to alcohol abuse. These alterations in serotonin activity can result in abnormal brain activity and psychological problems.

Alcohol and pre-existing anxiety disorders
Alcohol can trigger panic attacks in individuals with pre-existing anxiety disorders. While drinking alcohol may alleviate anxiety in the short term, it can increase the risk of panic attacks and worsen anxiety in the long term.
Alcohol affects the brain's release of gamma-aminobutyric acid (GABA), a neurotransmitter that typically has a relaxing effect. Small amounts of alcohol can stimulate GABA and induce feelings of relaxation. However, heavy drinking can deplete GABA levels, leading to increased tension and feelings of panic. This depletion of GABA can cause the brain to become "hyperexcitable," triggering panic attacks. Additionally, as the alcohol wears off, the brain reduces GABA levels further while increasing glutamate, resulting in heightened anxiety.
Individuals with anxiety disorders may turn to alcohol as an unhealthy coping mechanism or a form of self-medication to reduce their anxiety levels. However, long-term alcohol misuse can exacerbate existing anxiety disorders and contribute to the development of new anxiety symptoms. This can create a cycle where alcohol provides temporary relief from anxiety but ultimately leads to increased anxiety and panic attacks.
Withdrawing from alcohol can also induce anxiety and panic attacks. When individuals with anxiety disorders stop drinking, they may experience alcohol withdrawal, which can result in severe anxiety and panic attacks. This occurs due to the destabilization of natural GABA and serotonin levels, intensifying withdrawal symptoms and anxiety attacks.
It is essential for individuals with anxiety disorders to be cautious about alcohol consumption. Reducing general day-to-day anxiety levels and limiting alcohol intake can help lower the risk of alcohol-induced panic attacks. Seeking professional help to manage alcohol withdrawal and anxiety disorders is crucial for effective treatment.

Frequently asked questions
Alcohol has a profound impact on the brain, altering the levels of several chemicals, including GABA, serotonin, and dopamine. GABA is a neurotransmitter that helps regulate the nervous system and induces feelings of calm and relaxation. While small amounts of alcohol can stimulate GABA, heavy drinking can deplete it, causing increased tension and feelings of panic. This can be exacerbated if you already have an anxiety disorder or have had a panic attack in the past.
It is quite common for people to experience anxiety or "hangxiety" after drinking, even if they are not dealing with alcohol dependence. Research has also shown that many people with alcohol use disorders also experience anxiety disorders and vice versa.
Panic attacks are sudden waves of overwhelming fear and apprehension, along with physical symptoms like chest pain and tightness, sweating, a racing heartbeat, nausea, difficulty breathing, dizziness, feelings of faintness, or numbness in the arms and hands. It is important to note that panic attacks are not dangerous and will generally end in under 15 minutes.
If you are prone to anxiety or panic attacks, the best strategy is to abstain from alcohol or drink in moderation. Additionally, you can try to understand what is happening in your body during a panic attack and take steps to make yourself feel more comfortable. For example, the AWARE method involves acknowledging and accepting that a panic attack is happening and recognizing that you are afraid but not in danger.
