Six Scientific Facts to Wake Up Without a Hangover on New Year's

The BBC's Science Features team investigated the causes of hangovers, revealing that they are not so much due to the type of alcohol, but to how each organism metabolizes it. Contrary to popular belief, headaches from red wine are not caused by sulfites, but by quercetin, a substance that accumulates toxic compounds in the body. The myth of mixing drinks is debunked, as the intensity of the hangover depends on the total amount of alcohol consumed and genetic predisposition. Darker drinks contain more congeners, which worsen hangovers, but again, the volume of consumption is crucial. Furthermore, the research challenges the supposed benefits of red wine for the heart, with data showing an increased risk of stroke and hypertension. The psychological factor also plays a significant role, as the expectation of intoxication can enhance the effects, even with smaller consumption. Experiments showed that those who believed they had drunk more exhibited more "aggressive" behavior. Social influence also affects alcohol consumption, with a 2019 study showing that students with positive discussions about alcohol consumed more. The research highlights that understanding the scientific factors that contribute to hangovers can help prevent them, but is not a cure-all. In summary, a hangover is a complex phenomenon influenced by biological, psychological, and social factors. Excessive alcohol consumption, genetic predisposition, the presence of specific substances in drinks, and social influences are some of the factors that contribute to the onset of unpleasant symptoms. Prevention remains the best solution.
