Study results show: vitamin D supply is one of the decisive factors for onset and progression of flu epidemics is a major factor in the onset and progression of influenza the vitamin D supply. Norwegian scientists in a study published in the journal ‘International Journal of Infectious Diseases’ influenza epidemics draw this conclusion. Then get the infection and death rates at this flu epidemics with decreasing sun exposure and therefore less vitamin D supply. Particularly dramatically fail the seasonal differences in the proportion of deaths: this in “Vitamin D-Winter”, if the solar radiation is too weak for the vitamin D synthesis through the skin, to the 20-may increase. “Vitamin D has an antibiotic effect and strengthens the immune system. It is stimulated by the Sun’s ultraviolet of rays, made through the skin. In the winter months, when the Sun is too low for the vitamin D synthesis, decreases the vitamin D levels.
Then, the “sunshine vitamin” may his Protection no longer sufficient effect”, explains Professor Johan Moan one of the authors of the study, the relationships of the University of Oslo. In their study, the scientists of the University of Oslo pull data to flu epidemics in Sweden, Norway, the United States, Singapore and Japan, and compare the infection and mortality rates on a monthly basis with the strength of the Sun’s ultraviolet of rays.

Their goal is to make available the latest medical and scientific knowledge about the effects of moderate UV radiation on the people of a wide public.
