. People from all countries of the world are most interested in sex and often continue their descent on New year, Christmas and during other religious and secular holidays, say scientists in an article published in the journal Scientific Reports.

«The emergence of global networks and the social networks gave us an incredibly powerful tool for the study and observation of how changing the collective mood of the people and their behavior. We first studied the reproductive habits of people across the planet, observing how varied the interest in sex of network users at different times of the year,» says Luis Rocha (Luis Rocha) from Indiana University (USA).

There is a popular notion that peak fertility in most countries of the developed world accounts for September and August. The reason for this, as suggested by some of the inhabitants and scientists, is quite simple – couples are more likely to make the decision to have children during Christmas and new year holidays, or more often accidentally give birth to them, than at other times of the year.

Other researchers believe that this anomaly is not social, but biological origin, associated with as yet unknown biorhythms and various natural and environmental factors, for example, the amount of solar radiation or length of day that can invisibly affect people’s behavior. In favor of this, in their view, says that the autumn surge in the birth rate has approximately the same properties in different European countries with very different culture and social settings.

Roch and colleagues tried to verify this, drawing attention to the main drawback of such studies the authors have studied the lives of only the inhabitants of the Northern hemisphere and countries in which Christianity dominates or just European culture.

Scientists have tried to fill this gap by analyzing how often users of social networks write about sex in different seasons and trying to find a connection between this surge of interest in relationships with the opposite sex and fertility. To do this, they analyzed several million messages on Twitter and has studied the queries that users were left to popular search engines from January 2004 to February 2014.

As it turned out, between the holidays, sex and the peaks in the birth rate there was indeed a connection in Christian countries, the frequency of such requests has grown during Christmas and new year holidays, and in the Islamic States after the onset of Eid al-Adha, the last day of Ramadan, and almost 9 months after their occurrence, the birth rate began to rise sharply.

In addition, scientists have been unable to find any significant differences in interest in sex and procreation between the inhabitants of the southern and Northern hemispheres, which, they believe, suggests that this phenomenon is associated with climate, Earth’s position in orbit and other natural factors. Most likely, says Roch, it is purely social in nature.

«And Christmas, and Eid al-Adha can generate special collective mood which, apparently, is associated with increased fertility. It is possible that this is due to the fact that during these holidays adults often give gifts to children that encourages them to think about procreation and forces more attention to his family and family matters,» concludes Roch.
