Which drinks are dehydrating?

There are drinks that dehydrate. When we feel the urge to thirst, we immediately think of a refreshing drink. But we have to be careful about what we decide to drink, because not all liquids are the same. Some drinks, for example, contain ingredients that stimulate urination in a particular way. This condition can contribute to dehydration if consumed regularly and in large amounts. However, there are other drinks that we often think are dehydrating but actually contain liquids.

Beverages that cause dehydration: coffee, tea, and carbonated sodas with caffeine

Caffeinated beverages such as coffee, tea, cola soft drinks stimulate the central nervous system, which acts as a natural diuretic, increasing urine production. There are no single studies. According to some, it dramatically increases the amount of wee we do. Others argue that the increase is modest and therefore does not particularly interfere with the dehydration of the body.

The key word for these drinks is moderation.

The difference would be in the amount of coffee or tea we drink. A study showed that drinking 6-7 cups of coffee can significantly increase the amount of urine expelled. Up to 3-4, however, there should be no particular problems.

It can therefore be said that drinks that contain caffeine naturally have a diuretic effect. But if you don’t overdo it, there shouldn’t be any particular problems. The problem is that by drinking these drinks we often avoid drinking water. This is a serious mistake.

Alcohol and dehydration

Alcoholic beverages such as wine, beer and spirits can alter the water balance in our body by reducing the secretion of vasopressin, a hormone involved in regulating the expulsion of urine.

A study showed that the consumption of beer with 5% alcohol after exercise significantly increases the expulsion of urine, more than with an energy drink. Another research suggests that drinking two servings of wine in the short term increases the amount of urine expelled.

In practice, alcohol blocks the activity of pituitary glandresponsible for the production of vasopressin. The kidneys are then free to transfer whatever fluids they have into the bladder. This way it has to be emptied much more often than usual.

Dehydrating drinks: those that contain sugar, including fruit juices

The biggest problem here is that sugar acts as a diuretic, in addition to damaging teeth and making you fat. Drinks high in sugar are said to be hyperosmolar. In other words, they cause an accumulation of fluids inside the intestine. In this way, they cause dehydration at the cellular level. The presence of such an amount of water in the intestine can cause diarrhea. As we know, they are one of the main causes of dehydration, especially in children and the elderly. Remember that fruit juices are also very often loaded with sugars. I am really few those that contain 100% fruit.

Energy drinks and dehydration

Energy drinks can also cause dehydration problems because of the molecules they contain. In addition to caffeine which can have a slight dehydrating effect. There may also be taurine in some of these drinks. It is a molecule that has diuretic effects. Manufacturing companies often add it because it can improve athletic performance.

The golden rule is therefore to consume energy and alcoholic drinks in moderation to avoid dehydration.
