Many of us face winter depression and significant improved mood in the summer. In addition, the charge of physical energy in people often dry out in the cold season, and replenished with the arrival of heat. And, as it recently turned out, various seasons may also affect other human functions organism. For example, on mental activity.
Belgian researchers from the University of Liège have determined that the activity of cognitive processes in the human brain depends directly from the time of year. The results of this work were published. in the American science publication Proceedings of the National Academy of Sciences “.
Scientists are convinced that throughout the year the central nervous system Human systems work differently. The vast majority people’s mental abilities increase in the summer and decline in the winter, however, individuals are found whose brain, on the contrary, is much better functions with the onset of cold time. So if from year to year you feel that you start a certain season worse thinking, do not panic. Almost all residents planets are experiencing this.

Mental abilities and memory of ancestors
The study of the Belgians was attended by thirty volunteers. Throughout the year, experts analyzed mental processes of their experimental subjects. It turned out that twenty-eight people best understood in June, on the day of the summer solstice, after causing their quick wits to get worse. Two participants experiments, on the contrary, showed the best results in December, during the winter solstice. Volunteers were invited many tasks related to memory, concentration, puzzle solving and creativity.
The authors of the study suggest that such a feature of Homo Sapiens is associated with ancient rhythms. Once in the winter, for example, a person could get too little food, therefore at this time years he lacked physical energy and building materials for body tissues. As a result, the body reduced the activity of sites brains that were not critical to survival. Besides Moreover, do not forget about the cold, which forces the body spend extra nutrients on your heating.
