Of course, some people will think of coffee, because in theory, alcohol will make you unconscious, and coffee will make you concentrate. This trade-off should cancel each other out, right
Bottom line: You may think too much.
According to Professor Tony Moss of South Bank University in London, although coffee can make you concentrate, it can't inhibit the physiological reactions caused by alcohol, including hand-eye coordination and muscle movements.
To test this conclusion, Professor Moss did a physics test. He made five students equally drunk (calculating alcohol intake according to their weight) and asked everyone to do hand-eye coordination tests, all of which failed; Then the subjects were given a cup of coffee, and after drinking it, they were tested again, and all the results failed.
The experimental results are consistent with the research results in 2009. In the study, the level of drunken mice in the process of walking maze is far lower than that of sober mice.
Therefore, Professor Moss said that coffee can keep you excited. When the alcohol concentration in the blood drops, it can help you not to be extremely tired, but the best antidote to sober up is time.
So what causes people to have the illusion that coffee can help hangover?
"First, the role of coffee in promoting metabolism"
Because caffeine has the ability to improve human metabolism and help to excrete quickly, some people think that alcohol can be excreted quickly with caffeine, and the saying that tea and coffee can relieve alcohol slowly spread.
Goose, this method doesn't work. After alcohol stays in the body for four hours, the concentration begins to drop, and it takes about nine to twelve hours for the human body to excrete alcohol. There are two kinds of enzymes that help the human body break down alcohol, but coffee does not contain this enzyme that can help the human body break down alcohol.
Second, caffeine can stimulate the nerves and brain.
"When you drink five bottles of beer ton by ton, you have already felt the paralysis caused by alcohol on your tongue. At this time, when you make a cup of espresso, you will suddenly feel very awake … "In fact, if people who don't usually drink bitter coffee suddenly drink a cup of American coffee or espresso, their brains will feel stimulated instantly. This is because when a character tastes an unacceptable taste, the brain will subconsciously respond to stress, and short-term stimulation will make people feel very awake.
In addition, caffeine itself can not only improve human metabolism, but also make people feel excited, but this does not mean that it can offset the paralysis caused by alcohol.
Studies have shown that drinking coffee after drinking will turn the brain from extreme depression to extreme excitement, stimulate blood vessel dilation, accelerate blood circulation, and greatly increase the burden on the cardiovascular system. Therefore, it is still not recommended that you try this.
As for drinking, I think drinking a cup of iced coffee in summer is more enjoyable.
