Sex is seasonal, to some degree. Researchers have found that our sexual activity patterns ebb and flow throughout the year, and there’s an interesting change taking place right now.

Sex tends to reach its peak in the summer. Indeed, summer is the time of year when people tend to have the most sex. Sex typically declines in the fall and winter; however, there’s actually a surge that occurs during the month of December. Indeed, there’s a lot of evidence that sexual interest and activity reliably increase this month, and this is especially true with respect to the holiday week between Christmas and New Year’s Day.

We see this in terms of changes in condom sales, Google searches, conception rates, STD rates, and more. All of the evidence points to a brief bump in sexual activity this month. Check out the video below for a closer look at the various changes that take place in our sexual and romantic lives during December, as well as the biological, psychological, and social factors that might be playing a role in it.
