The secret to the success of the exam may be simple - drink a glass of water before the exam. Researchers found that children who had a glass of water before the exam played better, and the reason for this was presumably to be that the flow of brain cells would be smoother after drinking. In a survey, researchers at the University of East London studied two groups of boys and girls between 7 and 9 years of age. A group of children drank 250 ml of water. After 20 minutes, all children took the test. As a result of the test, children who drank water had a 34% higher score than children who did not drink water; in another, more difficult translation test, children who drank water had 23% higher scores than children who did not drink water; In the test of deleting a portion of the designated letters in a sequence, the children who drank water were also 11% higher. "However, the assessment found that the instantaneous memory of the two groups of children was not significantly different." Researcher Carolyn Edmond said: "In a series of tests, the children who drank water obviously performed better, we think that Drinking water is good for improving children's cognitive abilities.†Probably moisture can effectively improve the flow of information between brain cells. Similarly, earlier studies have shown that drinking water improves adult intelligence. Another study also showed that eating teenage fish once a week increases their IQ. A 15-year-old who regularly eats fish is significantly better at IQ tests than children who don’t regularly eat fish, researchers from a Swedish university said. Many studies have also shown that eating fish can prevent the decline of cognitive abilities. Pregnant women who eat more fish during pregnancy are also smarter.
