Why is the feeling of dryness or dehydration so strong after drinking alcohol ?

Why do people get headaches after drinking alcohol?

We will explain everything to you !

Alcohol is a "diuretic" , this means (to simplify) that alcohol will be a potentiator in the loss of water!

Most of us are already bad students when it comes to following daily water intake recommendations, and alcohol can amplify this potential for dehydration and related symptoms.

To quantify this, if you drink four 50ml beers, your body will eliminate more than a liter and a half of water!

Alcohol inhibits the secretion of an antidiuretic hormone “ADH”, also called vasopressin by the neurohypophysis. Vasopressin mainly has an antidiuretic role in the kidney, it allows the reabsorption of water because it acts on the collecting duct of the kidney. Thus, its role will increase the volume of reabsorbed water and decrease the volume of diuresis. Alcohol, it has an inhibiting effect on vasopressin, and will thus have a contrary role – and will therefore increase the volume of urine, hence the frequent urge to go to the toilet. It will also have the action of reducing the permeability of the renal tubules which normally allow tubular reabsorption. Thus, the volume of body water will decrease sharply. Alcohol will inhibit this hormone and thus the kidneys find themselves without this regulator and will seek to draw water from the body and eliminate it.

This leakage of water through the kidneys will cause the first signs of dehydration: the desire to urinate very often, dry lips and tongues, saliva is less abundant...

But know one thing, if the desire to drink ( thirst ) comes to you; your body is already dehydrated!

Why do people get headaches after drinking alcohol?

Indeed, upon waking up, after drinking a few glasses of alcohol, the headache is not the most pleasant. Alcohol makes you eliminate a large amount of water due to alcohol and so it is the cells; and in particular those of the brain (neurons and glial cells) which suffer and are dehydrated! Your body is suffering and needs to resolve this water deficit.

It is for this reason that Hydratis is often referred to as "the anti-hangover tablet". Hydratis was not designed to be used to avoid hangovers, yet it is effective! The active principles contained in Hydratis make it possible to optimize the absorption and assimilation of liquids by changing the osmolarity of liquids.

By coupling water molecules to sodium and glucose molecules Hydratis uses the principle of “cotransport” of water molecules. The passage of water through the digestive barrier with a supplement of trace elements and minerals not only allows faster absorption of liquids but will also support the metabolism in its muscle recovery and thus avoid muscle fatigue and will come to support the metabolism and immune system thanks to the zinc and manganese that each lozenge contains.

Hydratis is used by thousands of French people on a daily basis. Hydratis has benefited from thousands of positive reviews!
