Sun for the benefit and harm
|
The long sunny days of summer may increase the risk of "ideas" sexually transmitted diseases, and this is not only because that if good weather, the people are engaged in sex. Dutch researchers discovered: the highest incidence of papilloma virus rights during test noted in August. In their theory, sunlight suppresses immunity women.
Experts long suspected that solar energy is a powerful and seemingly mixed effect on the organism in terms of the development of various diseases, including tumours. The best example: the sun is the most powerful risk factor for skin cancers.
Many, however, believe that sunlight has more obvious influence, for example, predisposes to infection with papilloma virus through sexual intercourse. The virus is the most common cause of cervical cancer, disease in the United States of 10,000 women per year. Although the virus can cause papillomas education on the skin genitals, and the majority of those infected were no symptoms.
After other data Dutch scientists from 1983 to 1998 found in the sunny month of the solar year, the frequency of HIV peak. In Holland, in August the sunny month, and incidence of the virus twice as much of the winter. Surprisingly, as early as next month, September, the frequency of detection of the virus s. Sexual behavior is not an explanation of this phenomenon, so what is the reason for this?
No one can say exactly when the people are engaged in sex, but the display can be a rough time of conception children. The data shows that the maximum frequency conceptions in the Netherlands in March, fluctuations but this frequency throughout the year is only 10%.
Still, the authors believe that the virus affects throughout the year with about "the same force" and the summer sun makes its is far from bright case. It has been shown that solar activity can suppress education antibody and cell activation, the basic processes of the natural response to infection. The other observations of a link between sunlight and the exposure to the virus virus, adenovirus.
The relationship between the sun and cancer is a daunting one, and not simply by the light on the skin intact. Many studies have evaluated the frequency of cancer, according to the north people live. In general, it was found: the south, the less common cancers large bowel, prostate and breast, which may sunlight under the species has protective properties. Moreover, there is still the fact that people are heavily influenced by the sun, the risk of certain types of cancer lymphatic tissue at 30% less.
