Common Hangover Myths Debunked by Economic Researcher Shachar Lotan

Shachar Lotan, an economic and strategic researcher, intelligence officer reserve, and history enthusiast, addresses widespread myths about alcohol consumption and hangovers. In his blog, he explores historical distortions and their lasting impact, focusing here on common misconceptions related to drinking and hangover prevention.

Lotan explains that the popular advice to drink olive oil before alcohol to "coat the stomach" is ineffective. Since alcohol absorption mainly occurs in the small intestine, and the stomach is not a sealed container, olive oil only delays alcohol absorption but does not reduce the total amount processed by the liver, thus not preventing hangovers. This myth originates from Mediterranean folk medicine attributing healing properties to olive oil.

Another common belief is that mixing different types of alcoholic drinks causes worse hangovers. Lotan clarifies that chemically, alcohol is alcohol, and hangover severity depends on total ethanol consumed, drinking pace, and dehydration level. The perception that mixing drinks causes worse effects is due to drinking stronger alcohol later after initial consumption impairs judgment, not the mixing itself.

Finally, Lotan addresses the myth that alcohol kills brain cells. While chronic heavy drinking damages the brain and nervous system, moderate and occasional consumption temporarily impairs neural function without causing neuron death. Brain function improves as the body clears alcohol, unlike the lasting damage from prolonged abuse.

Lotan concludes by encouraging responsible drinking, suggesting drinking water alongside alcohol to reduce hangover risk and leaving superstitions aside. He emphasizes that alcohol consumption is an ancient social ritual, but understanding its effects is key to avoiding negative outcomes.
