Scientific American: Human sexual activity affects cognitive function, the health, την ευτυχία και τη συνολική ποιότητα της ζωής. Ναι, υπάρχει επίσης και το theme of reproduction.
The huge list of benefits is one reason why researchers are worried about declining sexual activity around the world, from Japan to Europe and Australia.
A recent study assessing what is happening in the US shows reductions from 2009 to 2018 in all forms of sexual activity.
The reductions are "not insignificant," according to the study authors, published Nov. 19 in the Archives of Sexual Behavior.
Between 2009 and 2018, the proportion of adolescents who did not report sexual activity, either alone or with partners, increased from 28,8% to 44,2% among young men and from 49,5% to 74% among young women .
The researchers obtained the information from the National Survey on Sexual Health and Behavior (National Survey of Sexuality Health and Behavior) and used responses from 4.155 people in 2009 and 4.547 people in 2018.
Respondents in the survey ranged in age from 14 to 49 years. The study did not investigate the reasons for this trend.
Scientific American he spoke with study authors Debby Herbenick and Tsung-chieh (Jane) Fu, on the underlying factors that could explain these changes.
Among other things, researchers say that social media, games and "hard sex" may contribute to this trend.
The depression, the health challenges, the loss of jobs work and the economic strain of the pandemic can also affect sexual interest and sex drive.
