People who drink more than the equivalent of seven cups of instant coffee a day are more likely to see things or hear voices, and even report sensing the spirits of the dead, researchers say.
In a study of 200 students, those who consumed high amounts of caffeine were three times more likely to have heard a non-existent person’s voice than those who consumed less than one cup of instant coffee or its equivalent a day.
Besides coffee, the researchers considered sources such as tea, chocolate, “pep” pills and energy drinks. The students’ susceptibility to hallucinatory experiences and stress levels were also assessed.
