You probably know that your physical health can affect your romantic relationships. Maybe you’ve heard about how couples fight less when the woman is ovulating, or end up divorced more often when they’re under too much stress. But did you know that it goes deeper than that? There are actually many fascinating ways in which science and psychology influence our love lives – here are thirteen of them:

The Way You Were Shaped Could Have An Effect On Who You’re Attracted To

Who we find attractive can be influenced by who we were as children – like the big brother who protected us from all those monsters in his closet or the sister we always fought with – and whether we see ourselves as an extension of them, or as separate. Generally, women tend to be attracted to men who remind them of their father (or another male role model), while men are more likely to look for women who take after their mothers.

“If you were raised by your dad and you’re a man, then it’s very possible that you’ll feel masculine in ways that lead you to date masculine women,” said social psychologist Susan Hughes, the co-author of Different Loving: The World Of Sexual Orientation Options. “Likewise if you’re a woman whose dad was distant or passive, it’s very possible that you’ll seek out an emotionally available man.”

Your IQ Could Affect How Long You Date Someone

People with higher IQs are less likely to experience a relationship before the age of 18 – and more likely to have a romantic relationship endure for at least nine years – according to research from the Open University in England. Researchers asked nearly 4,000 adults about their IQs, how long their relationships lasted, and if they had ever been intimate with someone before turning 18. The study also found that people whose parents were divorced or separated were more likely to have slept with someone before they turned 18 – as well as have shorter relationships overall.

Your Physical Attributes Can Influence How Long You Stay In Love

While good looks can make you happy, research shows it might not be enough to keep your love life going strong. According to one study , men who are rated as more attractive than their partners are more likely to be unfaithful, and women who are rated as more attractive than their partners tend to grow dissatisfied with their relationships over time. Other studies suggest that men tend to lose sexual attraction towards their female partner during the course of a long-term relationship – but they continue to love her as a person.

Your Genes Can Predict How Attached You Are To Someone

The degree to which you crave intimacy can depend on your genes, according to some researchers. The brains of people who were born without a particular gene (a serotonin transporter gene called 5-HTTLPR) respond differently when looking at pictures of their romantic partners, suggesting that they may need less intimacy in order to feel secure in the relationship.

Your Parents’ Relationship Can Influence How You Mate When You Grow Up

There’s a lot of talk about the ‘nature versus nurture’ debate when it comes to love, but new research suggests that while some aspects of romantic relationships can be explained by inherited traits, others may have more to do with how we’re raised. For example, a recent study revealed that men who saw their parents fight a lot were less likely to get married and stay married than those who didn’t see much conflict in the home growing up – perhaps because they carry an association between discord at home and pain in relationships. Similarly, another study found that children from homes where mothers did most of the housework tended to marry later in life compared to children from homes with more traditional gender roles, because girls growing up with strong role models tend to marry later.

Your Friends Might Have Just As Much Influence On Who You End Up With, As Your Family Does

While it makes sense that you’d end up with someone who’s similar to your mother or father (or anyone else in the family), your friends also play an important role when it comes to finding love. Research has shown that our social circles can affect everything from where we go on dates to what kind of relationships we seek out – for example, studies have found that people are more likely to be attracted to those who come from the same ethnic or educational background as their friends do.

How Well You Communicate Could Affect How Long You Stay Together

New research shows that the way couples communicate with each other has a direct effect on how satisfied they are in their relationship, and even whether or not they stay together. According to one study, “responsive” partners (those who make an effort to listen and respond well to what their partner says) were more likely to report having happy relationships compared to those who weren’t responsive. Another study found that people with dismissive-avoidant attachment styles (who usually prefer independence over intimacy) tend to end up in shorter relationships than others do – perhaps because moving quickly into a new relationship doesn’t give them enough time to miss earlier ones.

Your Hometown Might Determine The Kind Of Partner You Marry

Researchers from Stockholm University recently discovered that if your first serious relationship was with someone who lived nearby, you’re more likely to marry a similar kind of person than if you met other romantic partners. The Swedish study also found that people tend to marry those from similar economic backgrounds – even if they grew up in entirely different environments.

How Long You For The First Time Might Affect Your Relationship In The Long-Run

Some research has suggested that couples who have it within the first month of dating are more likely to break up over time compared to those who wait longer. One reason is that there may be less trust between a couple after only a short period of time – and too much distrust can put a strain on any relationship. Other research suggests that waiting until at least the third date means you’re less likely to let physical attraction get in the way of a healthy relationship.

Your Childhood Might Affect How Long You Stay In A Relationship

In addition to how your parents’ relationship influences the kind of spouse you end up with, a person’s childhood also affects their ability to make a commitment. Research has shown that people who had happy and healthy childhoods tend to be more committed adults since they have better self-regulation skills and are often better at taking others’ perspectives. Those who didn’t grow up in supportive homes, on the other hand, may struggle to feel secure when it comes to romantic relationships – possibly because they never learned how to trust other people or believe in themselves.

Hope this was helpful and remember – if you’ve got low-self esteem or tend to have bad judgment when it comes to love, no worries! We all make mistakes every now and then, but there are ways to get yourself back on track. It’s not too late, so don’t give up hope!
