If you’ve ever attended a concert in the middle of the week, you know the cautionary tale we’re about to tell. It’s the morning after an epic, memory-making show and you’re blurry eyes, tired limbs, and caffeine cravings are forcing you to remind yourself that it was all worth it. As it turns out, though, that cup of coffee you reach for the next morning in your post-concert haze could actually lead to deafness.
The research was conducted at McGill University, where albino guinea pigs were exposed to 110-dB sounds. Others were fed copious amounts of caffeine, and a third group of guinea pigs were exposed to both.
Scientists came to the conclusion that the guinea pigs who were exposed to both caffeine and loud noises took significantly longer to recover from sound damage. Hearing loss increased after day 15 of consuming caffeine and loud noises.
Describing the sound tests as “acoustic overstimulation events (AOSEs),” researchers concluded that a “daily dose of caffeine was found to impair the recovery of hearing after an AOSE.”
In other words, you should probably start wearing earplugs and chilling out on the caffeine unless you want to turn into a deaf albino guinea pig.
