We're officially two weeks into October and you know what that means? Hot girl summer has come to a close and many of us are looking for a warm body to snuggle with as the chilly air of fall turns into winter's brutal downpour of snow, sleet, and hail.

This need for physical intimacy during the colder seasons is commonly known as "cuffing season" and believe it or not, there's science behind that.

"Cuffing season has happened in our evolutionary history every time the days get darker," Dr. Wendy Walsh, a clinical psychologist who specializes in the psychology of love, sex and gender roles, told MTV. "We're walking around in DNA that's hundreds of thousands of years old. In our anthropological past, there was less food and resources [available], and hunter-gatherers' survival happened better if you were in a pack, if you were coupled up... [This] increased survival of any offspring that came out of it."

Also, social psychologist Dr. Justin Lehmiller explains more via NPR's 1A podcast about why humans flock together during the cooler months from a biological standpoint. "There are seasonal changes in hormone levels, specifically testosterone. So in the winter, men have higher levels of testosterone and that could potentially play a role here," Dr. Lehmiller says. "There is less sun exposure so you have less production of the neurotransmitter, serotonin, which plays an important role in regulating mood. That's partly why we see the winter blues in some people, where they feel more depressed in the winter so we may have that biological factor there making people want to partner up because it's a way of combating that feeling of loneliness."

We also have to take into account the social pressure to have a significant other at this time.

The late fall and winter are times when we reconnect with our families and it's nearly inevitable if you're single that your parents or grandparents ask you invasive questions about your potentially non-existent dating life.

And we can't forget about how there are loads of holiday parties — I'd be lying if I said it didn't feel good to have someone to share a cliché kiss at midnight on New Year's Day. There's no doubt in my mind that social pressure plays a big factor as to why online dating sites are at their busiest between December 26 and February 14. Additionally, searches on Pornhub for “boyfriend," “girlfriend," “cuddle," and “couple" increase significantly during the fall and winter months.

So before you move forward with the scouting, drafting, tryouts, and pre-season, don't forget these tips for a successful cuffing season:
