Despite the objective existence, the "winter depression" has not been recognized by scientists for a long time. However, it is impossible to deny the obvious: with the onset of cold weather and shortening of daylight, many begin to feel depressed. This is especially true for residents of northern countries. Lack of sunlight leads to excessive production of melanin, causing drowsiness and apathy.
In the period of cold weather and short days, many people note fatigue. Therefore, experts advise in the winter to go in for sports more often, to be in the fresh air. To compensate for the lack of vitamin D will help tanning beds.
For the sake of justice, it should be noted that the phenomenon of the "winter depression" is not fully understood by scientists. To establish the causes and mechanisms of this disease, more research is needed.
