Scientists at Stanford University have identified a worrying trend among individuals suffering from long Covid, indicating they may endure more severe hangovers after consuming alcohol. The research, conducted at the Post Acute Covid Syndrome clinic in California, involved participants who reported significantly worse hangovers since developing long-lasting symptoms of Covid-19. Among the individuals sharing their experiences, a 49-year-old woman described feeling overwhelmingly tired and groggy after only a glass of wine, a stark contrast to her previous tolerance. Similarly, a 40-year-old recounted an inability to enjoy more than one cocktail without suffering from effects akin to alcohol poisoning and persistent headaches, despite previously consuming up to seven cocktails in a night.

The study suggests the exacerbated hangover effects could be due to the virus and resulting inflammation weakening the blood-brain barrier. This weakening potentially allows more substances to penetrate the brain, thereby increasing sensitivity to alcohol. Additionally, the research participants noted aggravation of underlying health issues such as diabetes, cancer, and autoimmune disorders due to long Covid.

In the context of the UK, the Office for National Statistics has reported that around two million individuals are grappling with long Covid symptoms, including fatigue, shortness of breath, and loss of smell. With ongoing research into the effects of long Covid, the NHS has emphasized the importance of seeking support for those experiencing prolonged symptoms, offering services designed to aid in the management and care of long Covid’s impacts.
