Science of hangover

Drinking too much alcohol can lead to a series of unpleasant morning-after effects, commonly known as “hangover”.

Having a hangover is very common and it is also the most negative consequence of alcohol drinking.

Physical symptoms include: fatigue, headache, sensibility to lights and sounds, eye reddening, muscular pains and thirst.


Mental symptoms include: dizziness, probable cognitive and mood disorders, such as depression, anxiety and irritability.

Variety and intensity of symptoms change from person to person.

Moreover, hangover’s symptoms also depend on the type of alcohol drinks consumed and on the quantity of that.


Ahi! Headache!

Hangover headache is very frequent. Alcohol intoxication provokes vasodilatation and consequently… headaches.

Alcohol affects different neurotransmitters implied in the development of headaches such as histamine, serotonin and prostaglandin.  Anyways, the exact cause of hangover’s migraines is still unknown.


Alcohol irritates stomach and intestine, causing tissues irritation, above all when drinking highly alcoholic drinks.

Moreover, alcohol increases the production of gastric acid and pancreatic secretions. One or more of these factors can cause abdominal pains, nausea and induce vomit during a hangover.


Alcohol increases urine production. The consumption of 50-gr alcohols in 250 ml water (almost 4 drinks) causes the elimination of 600 to 1000 ml water in a few hours. .

Alcohol promotes urine production inhibiting the release of vasopressin from the pituitary gland. Then, reduced levels of this hormone prevent kidneys from absorbing water (this means to preserve water). So this process increments urine production.

Sweating, vomit and diarrhea are very common during a hangover. These can cause further dehydration and electrolytes unbalancing.

Light and moderate dehydration symptoms include: thirst, weakness, dizziness and giddiness. These are commonly observed during a hangover.


A hangover will make you sleep less and badly due to alcohol-induced excitement and high levels of alcohol in the blood cells.

Moreover, alcohol relaxes throat-muscles causing an increase in snoring and potentially a temporary stop in breathing.
