(Undated) — Drinking large amounts of caffeine could lead to an increased risk of hallucination. A new study out of Australia shows a major caffeine buzz can cause the imbiber to hear things that aren’t there. Researchers brought nearly 100 participants to a lab and administered large doses of caffeine to some of them. The researchers then gave the subjects headphones emitting white noise and told them the sounds of Bing Crosby’s “White Christmas” would be playing in the background. In spite of the fact the song was not actually played, some of the highly caffeinated participants reported they could hear it. The study concludes that drinking as few as five cups of coffee could increase a person’s chances of experiencing auditory hallucination. The study appears in the journal “Personality and Individual Differences.”
