Think that beer helps drown your sorrow? Think again: according to a new research at the University of Tokyo, alcohol actually help lock painful memory in place.
The researchers, led by pharmacology professor Norio Matsuki, gave mild shocks to lab rats to condition them to fear. As a result, the rats would freeze in terror and curl up the moment they were put in their cages.
Researchers then immediately injected the rats with ethanol or saline.
The researchers found that rats with alcohol in their veins froze up for longer, with the fear on average lasting two weeks, compared with rats that did not receive injections.
"If we apply this study to humans, the memories they are trying to get rid of will remain strongly, even if they drink alcohol to try to forget an event they dislike and be in a merry mood for the moment," the study said.
"The following day, they won't remember the merriness that they felt," it said.
