Scientists have found that a short nap during the day improves memory and makes the memories of important facts. The researchers conducted a study in the United States, where the practice of short siesta in the work have become quite popular in many companies. However, not all bosses are happy prospect that employees in the labor market are napping. Dr. Matthew Tucker, who led the study, noted that this idea is often met with resistance. Scientists have investigated the effect of short sleep on the process of remembering facts. The study was conducted on the students. In the experiment, subjects were asked to memorize pairs of words such as "watch -. Hands" was to save the students' ability to act - they were asked to trace exactly the mirror image of the complex system. Then half the group concluded in a soundproof room. Although they sleep for about an hour, on average, a dream took about 47 minutes. While they slept, the other group was relaxing, reading magazines and movies. 6 hours after the beginning of the experiment, both groups of subjects were tested again. Although both groups showed equally good results in the mirror, who had performed a siesta, was better on tests of memory, compared with those who are awake during the day. Those who napped remembered 15% more pairs of words. The researchers believe that the first phase of sleep (slow sleep) - a time when we have no dreams takes a few hours from the moment of falling asleep and may have a crucial role to play in the process of storing facts. At this time there is only the state that is required for the "folding" of the facts, so that they will be easily retrieved from memory. However, if you sleep longer and go through a phase of REM sleep, accompanied by dreams, the effect of the previous step be reduced to zero. The scientists warn that even help you remember a short siesta at the facts of the day, it is unclear whether this effect for long-term memory is extended.
