this is how our body really perceives excesses with alcohol

Theory (and experience in some cases) tells us that when we overindulge in alcohol, the next day is literally hell. However, despite being one of the most common afflictions in many societies, science continues to reveal the exact mechanisms that are activated in our body when the party is over. And far from being a simple problem of dehydration, the “morning after” is a complex chemical, immunological and cognitive breakdown.

A body map. Here science has wanted create a map with all the effects that there are on the body after a drunkenness, and for this the Catholic University of Leuven used a simple mobile app to be able to monitor a total of 34 young adults who are habitual drinkers.

Through this app, participants could cross-check questionnaire data, indicate the intensity of their hangover and even the quality of their sleep. But in addition, users pointed out the exact areas that hurt, felt weaker or numb in real time to clearly see that a hangover is more than a slight headache or having a dry mouth the next morning.

The result. Once all the participants had painted the areas where they experienced these physical sensations, the truth is that it was quite clear what was happening in the muscles. And in general terms, it was seen how the pain mainly affected the temples of the head or even the stomach discomfort that was felt as a hyperactivation of motility.

But at the other end of the spectrum we have the deactivation effect, which were areas painted with cold colors that signaled numbness or heaviness in the extremities. Although the fascinating thing about these “hangover maps” is that they are not purely psychological, since here science shows that these maps have real physiological correlates. That is, the areas that participants color align with measurable physical alterations, such as modulation of heart rate and visceral signals.

He leaves the laboratory. Traditionally, tests on the effect of alcohol have been done in a laboratory, analyzing all the variables that could change, but the reality is that no one drinks in such a measured way in the real world. That is why now going out into a much more real environment gives you a naturalistic touch which offers much higher validity.

Now an authentic representation of the multi-systemic hangover experience is literally being captured, balancing scientific rigor with the reality of how alcohol consumption occurs in our daily lives.

A risk pattern. Behind this study of hangovers lies a key neuroscientific concept, which is called interoceptive phenomenology. This is nothing more than our brain’s ability to perceive and process the body’s internal signals, so mapping how we feel alcohol and a hangover is of great help in identifying a risk pattern for alcoholism.

The key is in the literature that suggests that the way in which these physical sensations are processed is directly linked to our vulnerability to addictions. Here, interestingly, people who don’t have as many physical effects during a hangover may be at higher risk of developing an alcohol use disorder, since it may not feel too bad for them to draw a line. And this can be essential to be able to detect early in the future this serious problem that can literally destroy a life.
