A growing number of people are experiencing anxiety after a night out drinking, describing it as a nagging feeling of dread that can be overwhelming. The phenomenon has been dubbed "hang-xiety in social slang, and it's not just a matter of a bad hangover - research suggests that alcohol can affect the brain in complex ways, leading to anxiety and unease. Alcohol interacts with two key chemical messengers in the brain: GABA and glutamate. While GABA acts as a braking system, reducing nerve-cell activity, glutamate is involved in excitation and alertness. The effects of these chemicals are altered by alcohol consumption, which can lead to feelings of relaxation and lowered inhibitions - but also contributes to hang-xiety in the morning after. For those who experience hang-xiety, every day starts with a sense of trepidation, as they replay conversations and worry about what they might have done or said while drunk. As alcohol begins to wear off, the body's nervous system can experience an imbalance. This shift towards greater alertness and arousal can trigger anxiety in some individuals. The brain is constantly striving for equilibrium, but this delicate balance can be disrupted after a night of drinking. The effects of hang-xiety are not always directly proportional to the amount consumed the previous evening. Research suggests that existing psychological characteristics play a significant role in determining how anxious someone feels when hungover. This implies that genetics may also contribute to an individual's susceptibility to hang-xiety. A study conducted in 2019 by researchers at the University of Exeter involved 97 social drinkers who were compared with a control group that remained sober. The results showed that those who had consumed alcohol experienced a spike in anxiety the following day, particularly among individuals who scored highly for shyness before drinking. The research found that shy drinkers often felt more at ease during the evening itself, as alcohol helped to quiet their social nerves. However, this relief was short-lived, and these individuals were subsequently hit harder by anxiety the next morning. Their anxiety markers were significantly elevated compared with those who were not naturally shy. Innocuous moments can be distorted in hindsight, taking on a more embarrassing or regretful tone. A joke that seemed harmless at the time can become a perceived faux pas when replayed in one's own mind while hungover. The anxious feelings that linger after a night of heavy drinking can be just as debilitating as the physical symptoms themselves. This phenomenon is driven by a self-perpetuating cycle of worry and disrupted thinking. As one's mental state becomes increasingly clouded, it fuels further anxiety. For some individuals, this downward spiral can become overwhelming even after just two consecutive nights of excessive drinking. The mere act of navigating everyday situations, such as taking public transportation, can feel daunting when struggling with the Sunday scaries." This sense of unease is often triggered by a combination of factors, including dehydration and sleep deprivation. Research highlights that while falling asleep quickly after consuming alcohol may seem like a relief, it's not necessarily indicative of a restful night's sleep. Alcohol disrupts the normal patterns of rapid eye movement (REM) sleep, which plays a crucial role in emotional regulation. As a result, waking up dehydrated and sleep-deprived can significantly impair one's ability to cope with anxious thoughts. The brain's reduced capacity for coping with worry is further exacerbated by light and broken sleep patterns. Even if an individual manages to spend eight hours in bed, the quality of their sleep is severely compromised, making them more reactive to anxious thoughts. According to Dr Alanna Hare, President of the British Sleep Society, a tired brain is inherently more prone to heightened worry. Researchers emphasize that moderation is key when it comes to mitigating the negative effects of hangovers on mental health. Reducing alcohol intake and adopting strategies such as drinking water between alcoholic beverages can help alleviate some symptoms. Additionally, consuming food during one's night out can also provide benefits. UK guidelines recommend limiting weekly alcohol consumption to no more than 14 units, equivalent to six pints of beer or six medium glasses of wine, spread across several days. The symptoms of hang-xiety can be intense and overwhelming, making it difficult for individuals to shake off the feeling of dread that lingers after excessive drinking. According to experts, alcohol itself can contribute to the development of hang-xiety by exacerbating physical and mental health problems, rather than providing a solution. This is why seeking professional help from a general practitioner is crucial for those struggling with this phenomenon. Reframing one's thoughts about hang-xiety can also be an effective strategy in managing its effects. By recognizing that the dread and anxiety are temporary states, individuals can break free from the cycle of negative thinking and regain control over their emotions. Ultimately, understanding that hang-xiety is a normal response to excessive drinking can help alleviate its impact, allowing individuals to bounce back more quickly and maintain better overall health. --- Source: [BBC News Health](https://www.bbc.co.uk/news/articles/c32l4nqx5wvko?at_medium=RSS&at_campaign=rss) Published by Noti Group: https://noti.group/alcohol-affects-brain-chemistry-leading-to-anxiety/
