Recently, a British scientist discovered that it is not the effect of caffeine but the psychological effect of a refreshing cup of coffee. The University of East London chose 88 people who drink more than two cups of coffee a day to experiment and divide them into two groups. One group told them to drink decaffeinated coffee, but they actually drank coffee in general; the other group Instead, tell them to drink normal coffee, which is actually decaffeinated coffee. The results showed that the group who thought he had drunk caffeine had better attention and reaction. Judging from this experiment, coffee itself can not increase attention, but on the contrary, people who think that they have drunk coffee have psychologically depended on it.
New knowledge · Comments: Why does it feel really different after a cup of coffee in the early morning? It is said that it is likely that this cup of coffee has reversed the "fatigue effect" caused by no caffeine supply overnight. And studies have found that people who drink caffeinated beverages gradually become "resistance" to this stimulatory effect. No matter what, the psychological effect is also a role. For those senior “coffee espressorsâ€, starting from the aroma of coffee flowing into the nose, the role of that cup of coffee is even more refreshing.
