92 participants – who were told they were taking part in hearing tests – were set up with headphones and asked to press a buzzer every time they heard audio from Bing Crosby’s classic “White Christmas.” As a matter of fact, the only sound played into the headsets was white noise. But participants who drank at least 400 milliliters per day were significantly more likely to identify Crosby’s soulful croon.
On average, low-caf subjects heard it once. But stressed coffee guzzlers buzzed three times.
