We ve all had them before - well, of drinkers anyway - and despite their often horrendous nature, they don t seem to put us off getting boozy. But why do we actually get them, what is it about drinking too much alcohol that makes you feel like you want to crawl into a hole and cry the next morning? Let s find out some of the science behind the morning after. While we re all familiar with the delightful symptoms of a hangover (headache, trembling, nausea, fatigue, dehydration, diarrhea, etc), scientists actually understand relatively little about what causes them. For many years, dehydration was blamed as the primary cause for hangovers. Alcohol is a diuretic, meaning it makes you pee more and hence makes you lose water. It does this by, which prevents you from urinating excessively. Also, if you re shotting whisky or some other favorite tipple, you re probably not drinking much water. But even after you ve necked two pints of water as soon as you fall out of bed in the morning, you probably still feel dreadful. PrinceOfLove, Shutterstock. As points out, scientists have found that, in general, the levels of electrolytes (minerals in our bodily fluids) aren t significantly different between controls and people with hangovers, and even if they have spotted differences, they didn t seem to correlate with the severity of the hangover.


Furthermore, other studies have found no links between hormones associated with dehydration and hangover severity. So, dehydration probably isn t responsible for the majority of your hangover, but it might give you a banging headache. These are an unfortunate of your body attempting to restore fluid levels. Your blood vessels narrow, restricting the flow of blood and oxygen to the brain, which then tries to compensate by dilating its blood vessels, which can cause swelling. Although the brain itself can t feel pain, the discomfort may result from pain receptors in the lining that surrounds our brain. So we ve covered headaches, but what makes our stomach churn the morning after? Alcohol actually , causing inflammation of the stomach lining and delayed emptying of the stomach contents. It also causes us to produce more gastric acid alongside increasing the levels of pancreatic and intestinal secretions. Both of these can lead to that delightful nausea we often experience, or even cause us to throw up. Another candidate for the origin of a hangover is a toxic compound called, which builds up as a byproduct as our body processes alcohol. It s thought to be up to 30 times more toxic than alcohol itself, and has been found to produce hangover-like symptoms in studies. One final intriguing hypothesis is that hangovers are actually the result of our immune systems. One found that people with hangovers also had high levels of, which are substances secreted by immune cells that are involved in inflammation and cellular communication.


Normally, these help us fight off infections, but if you inject large enough doses into healthy people, they like nausea, headache and fatigue. Furthermore, some lines of evidence have hinted that abnormally high levels of cytokines could disrupt memory formation in the brain, which could help explain why many of us wake up totally oblivious of our late night shenanigans. So why do some people get worse hangovers than others? Well, some studies have suggested that it could be, but different studies have produced conflicting results. Some found that adolescents could tolerate hangovers better than adults, which has been supported by many animal studies, but a large Danish study that was conducted recently also found the opposite: hangovers actually seemed to decrease with age. It seems the jury is still out on this one. Another contributing factor is your choice of tipple. Different alcoholic beverages have varying amounts of compounds called, which are sometimes produced during the fermentation process or added in afterwards. Some studies have found that beverages high in congeners, like brandy and red wine, are much more likely to result in a hangover than drinks with few or no congeners, like gin and vodka. However, a more recent study found that congener content didn t actually cause differing effects on sleep, reaction time or memory the next day, despite participants reporting feeling worse on high-congener drinks. So, they might make us feel like dirt, but they don t seem to be affecting our performance. Happy hangover! Akos Nagy, Shutterstock.
