Health experts have issued warnings regarding the risks of alcohol consumption, specifically addressing common misconceptions and seasonal trends.

Initial guidance debunked the myth that daily moderate alcohol consumption is beneficial for heart health, noting that even small amounts can damage the liver and arteries. Medical professionals encouraged replacing alcoholic drinks with water to improve health and medication efficacy, particularly during vacation periods.

As summer progresses, experts highlighted an increase in alcohol consumption driven by tourism and high temperatures. They warned that alcohol can exacerbate dehydration by masking the sensation of heat and potentially contributing to higher rates of traffic accidents and drownings. In response to these risks, there has been an emphasis on non-alcoholic alternatives, such as non-alcoholic beer, as a way to maintain social habits without the health risks associated with alcohol.

Recent medical warnings have identified a specific condition known as ‘holiday heart syndrome.’ Dr. Ramón Ríos, head of Cardiology at Hospital Universitario Lucus Augusti, described this arrhythmia—characterized by palpitations or irregular heartbeats—as being directly linked to excessive alcohol consumption during holidays and social gatherings. 

Experts noted that the condition is further exacerbated by inadequate rest and the loss of essential minerals, such as potassium, sodium, and magnesium, caused by heat-induced dehydration. While environmental heat may not cause heart attacks in healthy arteries, it can trigger serious episodes in individuals with pre-existing risk factors or arterial fat.
