Hangovers – Headaches

Hello Children, it’s time to learn about one of the many upsetting effects of alcohol. Okay, I know most of you are probably people actually going through a hangover and you want to know why this is happening to you… I mean, you’re a good person (probably). So why oh why is last night hurting you today?

What is a hangover?

Unlike the movie ‘The Hangover’, where the characters pretty much go on an adventure the day after a rowdy night with seemingly no physical repercussions other than a couple tattoos, a hangover would probably make you want to sleep for a whole day.

A hangover, formally called a veisalgia, is basically the umbrella term for the after effects of drinking. It includes headaches, body aches, tiredness, weakness, thirst, nausea (sometimes vomiting), general stomach pain, diarrhea, and a slew of other symptoms like depression, vertigo and decreased attention.

Of course, you won’t likely experience all of these symptoms at once! There are different hangovers and they depend on how much you drink and how well your body is at detoxifying the alcohol. If you drink a lot and your body detoxifies alcohol at a very slow rate, then you will likely have an extremely bad hangover (unless you take some precautions – which will be explored in a later post!).

Why do we get hangovers?

If you recall last week’s post, where we discussed the effects of alcohol on the body, alcohol inhibits a hormone. This hormone, the antidiuretic hormone, is responsible for the reabsorption of water by your body’s kidneys. Without the activity of this hormone, the water that would have been retained by your body goes straight to your bladder and is then excreted. This loss of water results in your body becoming dehydrated, which leads to you getting a hangover.

Headaches and Hangovers, oh my!

Even though you are consuming a form of liquid, the amount of alcohol consumed is not as much as the amount of water lost during urination. This dehydrated state is what causes your headache, as the organs in your body are trying to their best to retain as much water as possible – even if that means stealing water from your brain. This results in your brain shrinking in size, making the membranes that connect your brain to your skull stretch – thus your headache. Crazy, huh?

Next week, we’ll talk about the relationship between Electrolytes and Hangovers.
