Hangovers and Your Brain: Craig Gunn Reveals the Hidden Costs
Probably the main key take home message is to just think about the consequences of a hangover... Even if their breath alcohol is at zero, they may still be impaired to levels kind of equivalent to acute intoxication.
Have you ever wondered what a night of heavy drinking does to your brain the next day? In this episode of Addiction Audio, host Suzi Gage chats with Craig Gunn about his eye-opening research on the cognitive effects of alcohol hangovers. Gunn's systematic review, published in the December 2018 issue of Addiction, dives into how those dreaded hangovers can mess with your memory, attention, and reaction times.
Surprisingly, there's not a ton of research out there—only about 500 papers—making Gunn's work all the more critical. Gunn breaks down the challenges researchers face when studying hangovers. Ethical guidelines prevent them from giving participants the same amount of alcohol they might consume on a wild night out, which means the hangovers studied in labs are often less severe than what people experience in real life. This limitation makes it tricky to fully understand the true impact of hangovers.
One of the key takeaways from Gunn's research is that even if your breath alcohol level is zero the morning after, your cognitive functions could still be impaired to levels similar to being drunk. This has serious implications for activities like driving or working, where sharp cognitive skills are crucial. So, if you're curious about how that last round at the pub might affect you the next day, this episode is a must-listen.
Craig Gunn's insights offer a sobering look at why we should all think twice about the hidden costs of heavy drinking.
