Scientists have proved that sexual attraction increases with increasing temperature.
Researchers from Brigham and Women's Hospital (Boston) place with colleagues from Harvard medical school of public health found three reasons explaining the phenomenon.
The first reason. In summer, the human body produces lots of serotonin-the hormone of happiness. The substance responsible for good mood and sense of pleasure.
The second reason. The sun's rays lead to lower melatonin levels in the blood. This substance at high concentrations reduces libido, which affects quality of sexual life. Relatively low concentrations of melatonin, in contrast, are associated with high sexual activity.
The third reason. It is associated with what people go in the summer. Usually in the summer we try to wear less clothing and expose the attractive part of the body. This factor increases the attraction between men and women. As a result, increased sexual activity at a biological level.
