BBC – “Cuffing season” is the cultural idea that singles look for short-term relationships during autumn and winter. The term likely emerged around 2009, but its origins are unclear. While dating app activity does rise between Nov and Feb, scientists say humans aren’t seasonal breeders like some animals. Instead, the trend seems driven by social and psychological factors. Research shows searches related to dating and sex peak in both winter and summer, not just the colder months. Some older studies suggested more sexual activity around Christmas, but recent evidence is limited. Experts say mood changes caused by reduced daylight, including lower serotonin and disrupted circadian rhythms, can increase the desire for connection. Winter loneliness, family pressure during the holidays, and the biological pull of bonding hormones like oxytocin may all play a role.
