Welcome to the world of love science! I’m Adrien, and today we’re diving into some intriguing insights about love, inspired by a Mental Floss video. Let’s explore how love works, from eye contact to genetics, and everything in between.
Did you know that simply making eye contact can spark feelings of love? In a 1989 study, researchers paired up 72 students and had them gaze into each other’s eyes for two minutes. The result? They felt more affection for each other compared to those who looked at hands or counted blinks. Eye contact is a powerful tool in the realm of love.
Watching romantic comedies might actually help your relationship. A 2014 study from the University of Rochester found that newlyweds who watched five romantic comedies a month and discussed them were less likely to divorce within three years. This activity reduced the divorce rate from 24% to 11%, debunking the myth that rom-coms create unrealistic relationship expectations.
Interestingly, a survey of 1,500 Americans revealed that two-thirds believe in love at first sight. However, a study from the previous year showed that frequent rom-com viewers didn’t necessarily believe in soulmates or love conquering all. It seems our beliefs about love are more complex than we might think.
Genetics might play a role in love at first sight. Many animals, like fruit flies, choose mates based on genetic compatibility. Some scientists suggest humans do the same, as people often marry those with similar DNA. A University of Colorado study found that married couples’ DNA was more alike than that of strangers.
Can newlyweds predict their marital future? A 2013 study suggests they can. Over four years, newlyweds took a computer test where their spouse’s picture flashed on the screen, followed by a positive or negative word. Faster reactions to negative words correlated with marital dissatisfaction.
Both men and women tend to lower their voices when speaking to someone they find attractive. A 2009 University of California study also found that a romantic partner can reduce pain in women, as participants reported less pain when looking at their partner’s picture or holding hands.
Love shares chemical similarities with obsessive-compulsive disorder (OCD). An experiment showed that people in love and those with OCD had 40% less serotonin than a control group. There’s even a condition called relationship obsessive-compulsive disorder (ROCD), where individuals obsess over their relationships.
Love can be as addictive as cocaine. A 2010 study revealed that both love and cocaine trigger significant dopamine release in the brain. Falling in love might also cost you two friends, according to Oxford University research.
The concept of “sexual imprinting” suggests people choose partners with features similar to their parents. An intriguing 1980s study found that men who kissed their wives in the morning had fewer car accidents and lived longer. Additionally, women who believe in gender equality are more likely to be in relationships.
A 2013 Finnish study asked participants to map emotions on the body. Love and happiness were felt throughout the entire body, a finding consistent across cultures. Physical signs of attraction include dilated pupils and a preference for partners with healthy immune systems.
In the first year of a relationship, both men and women experience increased nerve growth factors, causing those “butterflies” in the stomach. As relationships stabilize, these feelings may evolve.
Infidelity might have a genetic component. The DRD4 gene has been linked to promiscuity and unfaithfulness. A study found that people with a specific variation of this gene were more likely to report such behaviors.
In a study of 124 couples, most turned their heads to the right when kissing. This might be a genetic trait. Kissing may have evolved for a reason; saliva contains testosterone, and open-mouth kisses involve more saliva sharing, potentially boosting a woman’s sex drive.
Can love endure the test of time? A 2009 study scanned the brains of new couples and those together for 20 years. When shown pictures of their loved ones, 10% of the older couples had similar chemical reactions to the younger ones, suggesting love can indeed last.
Thanks for joining this exploration of love’s fascinating science. I’m Adrien, and I hope you enjoyed these insights. Feel free to check out more of our content. Until next time, take care!
Pair up with a classmate and engage in a two-minute eye contact session. Afterward, discuss with each other how this made you feel and whether it influenced your perception of each other. Reflect on the power of non-verbal communication in fostering connections.
Watch a romantic comedy with a group of classmates. After the movie, hold a discussion to analyze the relationship dynamics portrayed. Consider how these might influence real-life expectations and whether they align with the study findings on relationship success.
Research the role of genetics in mate selection and form debate teams. One team will argue that genetics significantly influence partner choice, while the other will argue against it. Present your arguments and engage in a class debate to explore different perspectives.
Using a body map, individually mark where you feel different emotions, such as love, happiness, or stress. Share your maps with classmates and discuss any patterns or cultural differences observed, relating them to the Finnish study on emotions and the body.
Conduct a workshop on the science behind kissing, exploring its evolutionary purpose and chemical effects. Create a presentation or infographic to explain how kissing might influence relationships and attraction, based on the studies mentioned in the article.
Sure! Here’s a sanitized version of the transcript:

Hi, I’m Adrien. Welcome to the salon! This is a Mental Floss video. Did you know that eye contact can influence feelings of love? In a 1989 study, researchers divided 72 undergraduates into male-female pairs and had them stare into each other’s eyes for two minutes. After those two minutes, they experienced an increase in love and affection for each other, more so than pairs who looked at each other’s hands or counted blinks.
That’s just the first of many facts about the science of love that I’m going to share with you today. A 2014 study conducted at the University of Rochester found that newlywed couples who watched five romantic comedies in a month and then discussed them were less likely to get divorced within the following three years. In fact, the authors claimed that doing so reduced the divorce and separation rate from 24% to 11%. Contrary to popular belief, romantic comedies haven’t been shown to make young people unrealistic about relationships.
A different experiment conducted a year earlier found that undergraduates who frequently watched romantic comedies weren’t more likely to believe in soulmates, love at first sight, or the idea that love conquers all. Interestingly, a survey of 1,500 Americans from diverse backgrounds found that two-thirds believed in love at first sight.
Love at first sight might even involve genetics. Many animals, including fruit flies, can determine who to mate with based on genetic compatibility, and some scientists believe humans do the same, although more research is needed. In fact, people tend to marry others with similar DNA. A study from the University of Colorado looked at the DNA of 825 married couples and found that their DNA was more similar than that of two strangers.
One study published in 2013 showed that newlyweds could likely predict whether their marriages would last. Every six months for four years, newlyweds took a computer test where a picture of their spouse quickly flashed on the screen, followed by a positive or negative word. Their reaction times indicated their relationship satisfaction; those who identified negative words faster reported more marital dissatisfaction.
Studies have shown that both straight men and women tend to speak in a lower voice when talking to an attractive member of the opposite sex. A 2009 study at the University of California found that a romantic partner has a pain-reducing effect on women. Researchers examined 25 undergraduates in relationships for at least six months and found they reported less pain when looking at a picture of their partner or holding hands with them.
Interestingly, love might have some chemical similarities to obsessive-compulsive disorder (OCD). One experiment measured serotonin levels in three groups: those recently in love, people with OCD, and a control group. The first two groups had 40% less serotonin in their blood than the control group.
There is also a disorder known as relationship obsessive-compulsive disorder (ROCD), where individuals become preoccupied with their relationships and often question whether their partner is “the one.”
Additionally, relationships have been compared to cocaine. A 2010 experiment revealed that the brain on love and the brain on cocaine show similar patterns, both involving a significant release of dopamine. According to another 2010 study from Oxford University, falling in love is typically accompanied by losing two friends.
The term “sexual imprinting” describes how people tend to choose partners with similar features to their parents. One study from the 1980s found that men who kissed their wives in the morning tended to have fewer car accidents and lived longer. Research from Rutgers University in 2007 indicated that women who believe in gender equality are more likely to be in a relationship than those who do not identify as feminists.
A 2013 study from Finland asked subjects to identify which areas of the body were associated with which emotions. They found that people reported feeling love and happiness throughout their entire body, a finding consistent across different cultures.
There are also physical symptoms of love; for instance, women’s eyes tend to dilate when they look at someone they find sexually attractive. The immune system plays a role in attractiveness as well; women typically prefer men with healthier immune systems, which is related to higher levels of testosterone.
Studies show that in the first year of a romantic relationship, both men and women experience an increase in nerve growth factors, which is why you might feel “butterflies” at the beginning of a relationship. However, as the relationship stabilizes, these feelings may change.
Some studies suggest that infidelity may have a genetic component. There’s a gene known as DRD4, and one study found that people with a specific variation of this gene were more likely to report being promiscuous and unfaithful in relationships.
In one study of 124 couples, the majority kissed by turning their heads to the right, while only 44 couples turned to the left. The researcher believes this may be a genetic trait, though this has yet to be proven.
The act of kissing might have evolved for a reason; studies have shown that saliva contains testosterone, and men have indicated a preference for open-mouth kisses, which involve more saliva sharing. Some scientists believe this is evolutionary, as it may enhance a woman’s sex drive.
Finally, some scientists believe that love can last. In 2009, researchers scanned the brains of new couples and couples who had been together for 20 years. After showing them pictures of their loved ones, 10% of the older couples had similar chemical reactions to the younger couples.
