It is believed that the best way to cheer up, is coffee. As far as this is true, I decided to test a group of American scientists. But they not only studied the effect of the drink on the body, but also tried to find him a replacement among several ineffective (at first glance) product.
Is a cup of coffee in the morning so invigorates the body and mind, that our productivity increases at times, and drowsiness He retreats into the evening? The answer to that question tried to find Professor Peter Rogers, from the University of Bristol. He conducted an experiment involving 20 volunteers, half of whom do not drink coffee. The second half, 10 of the avid coffee people were asked to refrain from practices flavored drink for 12 hours.
Both groups were tested for concentration and dexterity. Then the participants have given to drink coffee and then evaluated their ability. The experimental results have surprised the professor and even a little disappointed, as he likes to cheer up a cup of coffee.
"In general, participants who consumed caffeine showed a slow response, low intelligence and were more sleepy. After drinking the coffee of their performance has improved, but only to the level of the second group of volunteers. Coffee abstainers, participants also showed improved mental performance after drinking the beverage, but they have become more careful after that and anxious, "- quoted in the journal Peter Rodgers BBC News.
The professor concluded that regular consumption of coffee does not add mental abilities, but addictive.
The researchers also tested whether get rid of sleepiness by means of further products. They tested sugar, sage, and chewing gum. This time, the experiment was attended by 24 people, who were divided into 3 groups. During the week, they changed places for the purity of the experiment. Some ate sugary sweet, chew gum second, and the third took pills containing sage. An hour later, all were asked to do repetitive tasks.
Those who ate the sweet, coped with the task worst. Chewing gum is only cheered up by the fact that increases blood flow to the brain due to the constant movement of the jaw. Really worthwhile results showed only a sage. Tablets with this plant reduced sleepiness and improves concentration. Scientists explain the effectiveness of the sage by the fact that it contains a cholinesterase inhibitor (enzyme that destroys neurotransmitter atsetiholin) supporting its high concentration. Low atsetilhodina in the brain can cause problems with memory.
Researchers continue to look for unconventional methods of combating sleepiness, and at the moment the best way to think of this herbal tea with sage, not the coffee. (READ MORE)
