In today's busy life generally people used to drink too much of coffee completing as they were hearing some voices actually which are not there. This is due to having too much of coffee in their daily life.

Scientists warn that it's better to take five cups of coffee per day; otherwise people who consume more coffee will be hearing voices that are non-existed. In the experiment conducted with some volunteers, who take high levels of caffeine said that, they were listening to someone singing the White Christmas song even though the song was not being played.

The research stated that caffeine is the most frequently used psychoactive drug; the study proved that the health risks are if people consume too much coffee. The researches were done by 92 volunteers who were asked to listen to a constant fuzzy sound known as white noise.

In the research part Professor Simon Crowe, La Trobe University in Melbourne said that they also told the volunteers that within the white noise there may be parts of the song White Christmas and if you hear the voice, press a button. Which actually not included but the White noise was heard by the people who consume more coffee. They said that, drinking of too much of coffee is to overcome the pressure.

Drinking too much of coffee and stress will affect the likelihood of an individual experiencing a psychosis-like symptom. The research team found that only five cups of coffee is more than enough.

Finally, Professor Crowe quoted that caution needs to be exercised with the use of this overtly 'safe' drug.
