More babies are born in September than in any month in the United States, which means that during Christmas and nine months after the New Year – the most popular period for conception. Many scientists believe that rising fertility is a biological response to seasonal changes. As the temperature drops and the night becomes longer, theories suggest that humans begin to sink, cooperate and think more about sex.
However, new research in science reports shows that all post-holiday potbellies are more cultural and social than living creatures. Researchers at Indiana University and the Gulbenkian de Ciencia Institute in Portugal use data from all over the world to find that people have a strong interest in sex at important festivals, regardless of season.
To study the mood and interest in sexual activity, researchers conducted a study of Google Trends data from 2004 to 2014 and Twitter data from 2010 to 2014 in nearly 130 countries. In predominantly Christian countries, they found that sex was the highest on the web during Christmas, even in the southern hemispheres, such as Australia and Argentina, where Christmas was held in the summer.
In most Muslim countries, online search campaigns mark the Eid-al-Fitr, an important festival ending Ramadan. The researchers say this is particularly interesting because Ramadan is based on lunar calendar and observed in different seasons, depending on the year.
Associate chief author Dr. Luis Rocha, a professor of informatics and associate professor of cognitive sciences, said the study was the first “planetary” study of human interest and desires as they dealt with sex and sexuality at different times of the year Reproductive. Indiana University. He said they strongly support the interest in orgasm during major cultural or religious celebrations.
Interest in sex online does not mean just searching for porn. “We have seen an increase in the number of people searching for general knowledge, including medical terms, contraception, etc. This increase correlates well with the increase in birth nine months later.”
Researchers can not say why sex is more than usual during the holidays. But their Twitter analysis does provide some extra clues about what we think of this time of the year. The interest in sex is associated with the increased use of tweets related to the vocabulary of pleasure, safety and calm.
“Every time this emotion appears on Twitter, it leads to more searches for sex.” We can only guess now, but maybe when people feel happy and less anxious-at the end of the year and at holidays, at In this case, they are more likely to think about starting a family.
Other theories suggest that festivals are celebrations, social gatherings, and periods of increased drinking, whereas those who do not want to be alone may be more likely to find mates in the seasons.
But the new study did not find a similar trend in birth rates after other major festivals, such as Thanksgiving in the United States, Easter in Germany and France. Rosa said: “These other holidays involve food, family and alcohol, so it does not seem like just these elements.
Another possibility, he said, is that both Christmas and Eid is family-oriented. All involve giving children gifts, the birth of Jesus around the Christmas center. He said: “Perhaps people in this environment feel more impulsive family growth.
Rocha wants his team’s future research to answer these questions. These findings may also have an impact on public health and policy: they can help officials plan more effective campaigns around safer sex at some point of the year, especially in developing countries that lack reliable data on birth rates.
