It turns out that the invigorating effect of coffee is an illusion. The scientists from the University of East London have conducted an experiment. They gathered a group of 88 volunteers aged 18 to 47 who had been drinking coffee for years. The volunteers were promised coffee containing caffeine. In fact, there was no caffeine in it. As a result, the participants still had an improved mood and increased activity.
To assess the status of volunteers, they used special tests that check mental performance, reaction speed and mood. It turned out that the volunteers would cope better than the representatives of the control group who drank regular coffee with caffeine. Hence, the fact is that after drinking coffee people expect more energy. It produces the same effect as a placebo.
Nevertheless, it is known that caffeine is a powerful stimulant that can cope with fatigue. Some studies have shown that three cups of coffee a day can reduce the risk of developing Alzheimer’s disease – most likely by initiating a special reaction in the brain which does not allow cells to be damaged.
