Why in autumn we are sad?

With the onset of autumn on many people, no apparent reason rolls longing, and the less the sun looks out, the stronger. There is a scientific justification.

In the human body there is an enzyme that translates the amino acid tryptophan in serotonin – hormone of happiness. The process catalyst is vitamin D, which is produced in the skin under the action of solar, or rather, ultraviolet rays. When it is not enough, a person has a mood, he is hesitated and annoyed on trifles, and even reasons for joy he seems to be less. The most "depressive" period – from mid-October to February. At this time, many complain about the depressed and semi-alone state. All because because of the peculiarities of the atmosphere in the fall and winter, sunlights with difficulty reach the earth. In addition, at this time of year, a person is completely dressed, and hence the skin does not receive enough vitamin D. Even a campaign into the solarium is not able to solve the problem – vitamin D in this case, though it is formed, but in insufficient number. But you can get a problem much more dangerous – the development of melanoma.

The lack of vitamin D affects not only in the mood, but also on immunity. The protective functions of the body weaken, and the person begins to hurt more often, which also does not contribute to raising the spirit.

Most of all people are subject to autumn, whose work is connected with constant stress. And women dark weather are heavier. And for meteo-dependent people, especially the elderly, low pressure, which is typical of autumn weather, and the lack of bright paints is at all becoming a test.

Help the body is simple: to sleep enough hours, rest, walk, lead an active lifestyle and, of course, eat. Although the main source of vitamin D is the sun, it also enters the body from food. For example, contains in butter and fish. Available in Bad form. So the lack of solar vitamin can well fill.
