People who drink a lot of coffee every day can experience visual and auditory hallucinations, the Air Force reports..

Scientists conducted a study in which two hundred students took part. Volunteers described how much coffee they consume per day. It turned out that those who consumed more than seven cups a day could experience hallucinations and hear some voices, unlike those who consumed one cup of coffee a day. The study was published in the journal Personality and Individual Differences.

However, experts believe that the results of the study do not prove a causal relationship. They also reported that many people hear auditory hallucinations, and this does not indicate the presence of a mental disorder. This is just the first step towards studying the factors associated with hallucinations, said the doctor in the field of philosophy and psychology Simon Jones.

In stressful situations, there is an active secretion of the hormone cortisol in the body, which is also produced after consuming caffeine. Perhaps an increased level of cortisol could affect the occurrence of hallucinations, researchers suggested. For this reason, experts consider it expedient to seek in the future the relationship between mood and the effects of caffeine.
