A drink of water

American scientists have found that the cause of irritability and temper of man can be so-called mild or moderate dehydration. Psychologist Lawrence Armstrong of the University of Connecticut, said that dehydration is equally bad for those who sits all day in front of a computer and those who participate in the marathon. Once a person loses 1-2% moisture, the first signs of thirst and fatigue. As part of the experiment, which lasted for 28 days, volunteers aged 20 to 23 years old were carried out every day on the treadmill for 30-40 minutes, and then tested with the rate of reaction, concentration, cognitive abilities. The researchers compared the results of tests carried out before and after exercise. Psychologists have found that the hardest women suffer dehydration. The lack of fluid can cause them headaches and fatigue, it is more difficult to focus on the task at hand. Thus men dehydration can cause irritability and anxiety. Psychologists remind us that healthy people should drink a day at least 8 glasses of water.
