New research reveals a detailed map of hangover sensations, showing increased discomfort in the head, chest, and abdomen, and weakness in the limbs. The study challenges the idea that hangovers deter drinking and highlights age-related differences in hangover experience.
As the bank holiday weekend approaches, many are anticipating celebratory drinks. However, new research offers a detailed insight into the physical toll these indulgences can take.
Scientists have meticulously mapped the sensations experienced during a hangover, revealing a consistent pattern of discomfort and weakness across the body. The study, conducted by researchers at UCLouvain in France, involved 34 regular heavy drinkers aged between 18 and 35. Participants were asked to document their drinking habits, hangover severity, and sleep quality over several weekends.
Crucially, they used a smartphone application to colour-code a body outline, pinpointing areas of heightened sensation – such as pain or throbbing – and diminished sensation, like weakness or numbness. The intensity of the colour corresponded to the strength of the sensation felt. The resulting topographical maps revealed a striking correlation: hangovers consistently manifest as increased activation – meaning heightened discomfort – in the head, chest, and abdomen.
Conversely, the lower limbs, hands, and feet experienced deactivation, characterized by weakness and reduced energy. This pattern challenges the widely held belief that hangovers serve as a natural deterrent to future alcohol consumption, as the study found no significant link between hangover severity and a reduction in subsequent drinking. Interestingly, the research also highlighted an age-related difference in hangover experience.
Participants in their 30s reported significantly more intense bodily sensations compared to those in their late teens and early 20s, potentially due to metabolic and physiological changes in how the body processes alcohol as we age. The team suggests this body mapping tool could be valuable in identifying individuals at higher risk of developing alcohol addiction, offering a new avenue for preventative intervention.
The activation clustered in the torso, abdomen and head overlaps with symptoms such as heart pounding, thirst and headaches, while deactivation, prominent in the abdomen, limbs and hands, aligns closely with nausea and weakness. Beyond the detailed body map, the study also explored the relationship between hangover severity and various factors.
While there was a strong correlation between the intensity of bodily sensations and the perceived severity of the hangover, the level of intoxication the night before did not reliably predict the next-day discomfort. This suggests that individual physiological responses and other factors play a significant role in hangover experience.
Furthermore, the research touched upon the types of drinks consumed and their potential impact on hangover symptoms. While mulled wine, a popular festive choice, was identified as potentially worsening hangovers due to its high sugar content and fluctuating blood sugar levels, tequila was surprisingly noted as being less likely to cause a hangover, possibly due to its production process.
Previous research from Lifesum highlighted the importance of nutritional recovery, ranking countries based on the nutritional quality of their traditional hangover foods. Japan’s miso soup topped the list, while the UK’s Full English breakfast languished at the bottom, deemed detrimental to hydration and energy levels. Ultimately, understanding the complex interplay between alcohol consumption, physiological responses, and recovery strategies is crucial for mitigating the unpleasant effects of a hangover and promoting responsible drinking habits
