Unlike what is considered, cold beer does not serve to moisturize the body – Society

At high temperatures, many people are tempted to take a "beer" or some other fresh alcoholic drink. However, alcohol consumption not only increases the sensation of heat and discomfort, but may also entail a greater health risk, as it suppresses the body’s defense and self-regulation mechanisms.

The situation may involve more chances of heat stroke and even the risk of fainting. But on the other hand, it can enhance certain natural reactions that can also cause decompensation.

More sensation of warmth. One of the effects of alcohol is vasodilation, which implies a feeling of greater heat immediately after it is consumed. This was explained by Sergio Saracco, director of toxicology in the province of Mendoza.

hypotensionThis substance acts at the level of the central nervous system and suppresses it, but also because it is a vasodilator, it causes a drop in blood pressure. This can enhance this effect, which itself generates heat and adds a sense of exhaustion and lack of energy, which the body produces in this battle with the heat. This is what compensation and self-regulation is a big effort for him. That is why you come to the night especially tired.

"On very hot days, the body compensates for heat loss and produces vasodilation, if a person consumes alcohol, there is more pronounced hypotension and the risk of fainting increases."said the specialist.

dehydrationTo compensate for external heat, the body uses perspiration, but at the same time, if it detects dehydration, it prevents fluid loss. This happens with the help of antidiuretic hormone, which controls the fluid balance in the body if it has less urination.

Alcohol consumption can change this: “Alcohol inhibits the antidiuretic hormone and, therefore, has a diuretic effect, changes the normal physiological defense reactions of the body to certain situations, in this case, the high temperature violates the natural defense response,” he explained.

Excessive fluid loss also implies that salts, which are necessary for organic functioning, can affect health. It also affects blood pressure.

sweatingThe professional also said that it can affect sweating, being a vasodilator, "it produces more and helps with dehydration."

Believe that alcohol is hydrates. It can be mistakenly assumed that any of these drinks moisturizes and therefore does not consume what it does. This is not the case, and therefore you should always take fresh water, especially when it is hot, to compensate for the loss of fluid.


Consumption of alcoholic beverage is so included that for more than one it is difficult to avoid the temptation of cold beer after a hard day of heat. For others, it will be another drink. The question is whether it can be done or not. Although the ideal is to avoid this: if this is not possible, there is a strategy.

You must drink fresh water before drinking.

The doctor explained that if you arrive with heat and are going to drink an alcoholic beverage, it will happen that you consume more and also do not hydrate. Thus, ideally, you need to take one or two glasses of fresh water to cool the body, and then drink the appropriate drink.


High temperatures cause discomfort, heaviness, exhaustion, headache, and even irritability and bad mood. However, the greatest risk is heatstroke, which may have more risky consequences, especially for certain people.

This is an increase in body temperature, which can occur when at high temperatures prolonged exposure to the sun, exposure to poorly ventilated or hot conditions, or physical exertion occurs.

In this situation, the body is dehydrated, loses the fluids and salts necessary for its functioning. The ability to regulate its temperature is changed and decompensated.

Considering the current heat wave, the Ministry of Health makes certain recommendations to avoid risks.

How to prevent heat stroke?

Dehydration or gastrointestinal disturbances can be prevented by drinking large amounts of water throughout the day, avoiding exercise outside at bright hours and staying in cool, ventilated places. In addition, you should use light clothing that contributes to heat loss, and children should be breastfed regularly.

Who is more at risk?

Infants and children, the elderly and people with chronic illnesses (heart, kidney, mental or neurological, among others) are at greater risk. Those who have a disability, children with a fever for another reason or diarrhea, obesity or malnutrition. Also those who abuse alcohol, drugs or burned in the sun.
