Coffee healthy drinking a lot of coffee will lead to auditory hallucinations

Coffee has become the darling of many people's taste buds, but whether drinking coffee is good for people's health is still a controversial issue. Recently, researchers from La Trobe University in Australia have come to the startling conclusion that drinking more coffee may lead to auditory hallucinations.

In the study, published in the journal Personality and individual differences, 92 non-clinical subjects were exposed to high or low levels of caffeine under high or low stress. After that, they need to listen to a background noise, be ready to find out the melody of "White Christmas" hidden in it, and report it to the experimenter. The noise includes a variety of frequencies and sounds like a constant "sizzling" sound.

Experiments showed that subjects who were in high-stress situations or ate high levels of caffeine were more likely to report hearing the melodies of the song. But the truth is: this song never appeared.

Professor Simon Crowe of the School of Psychological Sciences, the author of the study, explained: "High stress levels are associated with mental disorders, and caffeine has long been linked to auditory hallucinations. The combination of caffeine and stress affects an individual's likelihood of developing psychopathic symptoms. "

Professor Crowe believes their research helps explain why stress promotes signs of schizophrenia in non-clinical samples. Coffee, on the other hand, has only recently been found to increase the risk of auditory hallucinations. High caffeine intake and superimposed stress events in life will make normal subjects more likely to have auditory hallucinations. Everyone is standing on the continuous spectrum from health to schizophrenia, so "everyone, to some extent, may experience those symptoms." The significant effect of stress on auditory hallucinations confirms this point.

As we all know, coffee can act on the central nervous system of human beings, helping people temporarily expel drowsiness and shake up their spirits. Unlike other stimulants, this most widely used psychoactive substance has a legal identity. People can enjoy coffee as much as they want, regardless of any specification. Most people in North America, South America and Western Europe regard it as an indispensable daily drink. However, Professor Crowe is a wake-up call: drinking five cups of coffee a day can trigger auditory hallucinations-people still need to pay more attention to this blatant "safety addiction".
