Pharmacist Debunks Electrolyte Hangover Myth: Water is Key, Says Viral Video

Are Electrolytes the Hangover Cure? A Pharmacist Explains the Truth Spain – May 16, 2025 – A recent video by Spanish pharmacist, farmaceuticofernandez, is going viral, dispelling a common misconception about preventing hangovers. Many believe that adding electrolytes to alcoholic beverages prevents dehydration and the subsequent morning-after woes. However, farmaceuticofernandez explains that the primary cause of alcohol-induced dehydration isn't electrolyte loss, but rather the alcohol's effect on the antidiuretic hormone (ADH), which regulates water retention. "When you drink alcohol," explains the pharmacist, "it affects the antidiuretic hormone, making you urinate more than usual." This leads to significant fluid loss, the main culprit behind a hangover. The video shows a young woman adding electrolytes to her drink at a bar, a common practice among partygoers. The pharmacist uses this as a visual example to highlight the misconception. He emphasizes that while electrolytes won't harm, they are not a substitute for water. The best way to combat alcohol-related dehydration is to drink plenty of water throughout the night and before going to bed. The pharmacist's clear and concise explanation, combined with the video's relatable visuals, has resonated with many viewers, leading to its widespread popularity. The video serves as a valuable reminder of the importance of responsible alcohol consumption and proper hydration.
