Confusion
One of the less well-known side effects of too much caffeine is caffeine confusion. It refers to feeling confused and disoriented after consuming too much caffeine. The confusion can be so severe that it leads to temporary mental impairment and memory problems. Caffeine confusion is sometimes also referred to as caffeine psychosis.
While caffeine confusion is not a well-studied phenomenon, some evidence suggests it is real. For example, one study found that people who consumed large amounts of caffeine were more likely to experience psychotic symptoms like paranoia and delusions than those who didn’t. Another study found that people with schizophrenia who consumed large amounts of caffeine were more likely to experience psychotic symptoms than those who didn’t consume caffeine.
So, what causes caffeine confusion? It’s not entirely clear, but the combination of sleep deprivation and high-stress levels may play a role. When an individual is tired and stressed out, their body may not be able to handle the extra stimulation from caffeine as well as it normally would, resulting in confusion and disorientation.
