Australian researchers found that drinking five regular cups of caffeinated coffee may raise the risk of auditory hallucinations, according to a small study published in the journal Personality and Individual Differences. LaTrobe University researchers asked 92 people with varying levels of caffeine intake and stress listen to three minutes of white noise via headphones. The study participants were told that Bing Crosby's "White Christmas" would be playing in the headphones, and when they heard it, to hit a buzzer. While the song never actually played, the people who were hopped up on five or more cups of coffee buzzed three times on average, while the low-caffeinated people buzzed just once on average, the Herald Sun in Australia reported.
