"Caffeine Linked to Hallucinations" -14

"Caffeine Linked to Hallucinations"

People who drink a lot of caffeinated drinks and coffee daily, are reported to more likely have out of body experiences and hear voices, than those you do not drink as much. The link between the two makes sense, since when the body becomes stressed it produces more of the hormone cortisol, which if elevated it can cause people to hear and see things. The hormone cortisol can also be regulated by caffeine, making it possible for caffeine users to see and hear these unexplained things. Several scientists tried out an online survey to see what coffee drinkers where experiencing. The survey had the answer from mostly women that they have had outer body sensations. These women were used to having two to three cups of coffee a day, which then caused them to have the outer body experience and the hallucinations. It is still possible that coffee is not the reason for these people having hallucinations, since they do not know their use with alcohol or any illegal drugs. There was a search done years ago also connecting caffeine to hallucinations, then there is the question about those who have developed a tolerance, could they also develop a tolerance for the hallucinations.
