Study discovers link between caffeine and hearing loss after a concert
New research published in the Journal of the American Medical Association shows a link between caffeine and hearing loss, according to a study conducted by the Research Institute at the McGill University Health Centre. Researchers used animal subjects and exposed them to a sound level of 110 dB, (a decibel level which is closely comparable to that of a rock concert) for an hour. While one test group abstained from caffeine, the other was given a “daily dose” at 25mg.
Subjects were monitored for a total of 15 days. Both groups encountered temporary hearing loss a day after noise exposure; the caffeine-free group recovered after eight days, while the other group’s maladies continued to persist.
“Our research confirmed that exposure to loud auditory stimuli coupled with daily consumption of 25mg/kg of caffeine had a clear negative impact on hearing recovery,” says Dr. Zawawi, an Otolaryngologist and member of the McGill Auditory Sciences Laboratory.
Though McGill’s team intends to conduct additional research, this time on human subjects, they assert that the popular stimulant has a definite effect on the recovery process for animals’ brains and bodies alike, which may be unfortunate news for live music attendees who consistently consume caffeine.
