7 Ways Relationships Make You Happier (According To Science)

It's not all tears and Tinder.
|

The Internet, and particularly Tinder's own Twitter account, was in a tizzy this week over Vanity Fair's detailed look at how online dating apps are shaping the way Millennials form romantic relationships.

If the article is to be believed, all that swiping left and right has created a culture of detachment and a lack of romance. It's "the dawn of the dating apocalypse," as the Vanity Fair writer Nancy Jo Sales put it.

And while some corners of the online dating world may be dismal indeed, one central criticism of the article has been that it didn't show the myriad of people who are seeking lasting bonds on apps like Tinder and OKCupid. After all, one-third of all married people have dating apps and websites to thank -- and a 2013 study found that couples who met online had higher marriage satisfaction

In other words, it's not so much how you meet that accounts for personal happiness. Instead, it's what happens next, according to a multitude of research on the role relationships play in overall life satisfaction.

Playing cupid makes us happier.

Not only that, the study found the more unexpected the match, the greater happiness the matchmaker experienced. As Shankar Vedantam, NPR's social science correspondent, explained, "this probably explains why, if you're single, your matchmaker friends keep trying to introduce you to people with whom you have absolutely nothing in common."

However, as we know, unlikely matches are sort of eliminated in online dating thanks to algorithms that connect people based on similarity. Perhaps we should ditch the dating apps entirely and just use and play matchmaker the good ol' fashion way (kidding... sort of).

Interpersonal relationships lead to greater life satisfaction...

We often think of romantic relationships as the bread and butter of connectedness and happiness (and those are certainly a big component) but this is evidence that all of our relationships hold merit. A 2007 study published in the Journal of Positive Psychology found that strong social relationships with others predicted greater life satisfaction, which essentially means a more positive evaluation on how their life is currently going and how it will go in the future.

...But that doesn't necessarily mean we have to have a wedding.

In a meta-analysis of 18 studies on long-term married couples and "cognitive well-being" (i.e. what researchers used to measure life satisfaction), a report published in the Journal of Personality and Social Psychology found that life doesn't necessarily improve after we tie the knot. Aside from an initial "honeymoon effect," the study authors discovered that the participants did not feel happier or more satisfied with their lives once they were married

Romantic relationships have a greater influence on life satisfaction than work.

This is very telling: We may regard relationships more highly than success at work, according to 2013 research from the National University of Entre Rios in Argentina. The study analyzed more than 200 participants ages 23 to 27 to determine how love and work rank in terms of life satisfaction. "A much stronger stability was found in love than in work domain," the study authors wrote.

Seniors in sexually active marriages self-report feeling personally happier.

Physical intimacy in a relationship is crucial to our own personal satisfaction. An analysis of findings from the 2004 General Social Surveys found that older couples who engage in regular sexual activity are more likely to not only be happier in their relationship but happier in their own lives as well. Additionally, research shows that having sex can reduce our stress levels.

Our personal longevity is better if we have strong social relationships.

Adding years to our lives may lie in the company we keep. An analysis of nearly 150 studies published in the journal PLOS Medicine found good social relationships -- which certainly include romantic relationships -- had a profoundly positive impact on reducing the risk of mortality. The participants with strong social bonds had an increased likelihood of survival by 50 percent.

Most of all, love is the key to a happy life.

It seems The Beatles were onto something when they crooned that "love is all you need." According to a Harvard study that analyzed data over the course of 75 years (yep, that's almost a century), loving relationships are crucial to a happy, fulfilling life. 

It's worth noting that the study only included men, but the authors say that the results can provide an important insight into the human condition. George Vaillant, a Harvard psychiatrist and one of the study's researchers, says the the findings support two main concepts of happiness. "One is love," he wrote. "The other is finding a way of coping with life that does not push love away."

In other words, humans love to love. Simple as that.

7 Awesome Ways Relationships Can Boost Your Health
Relationships Can Help Boost Cancer Survival ...(01 of07)

A just-published study published in the Journal of Clinical Oncology suggests that marriage may help improve cancer survival rates. According to the findings, men and women who were married were about 20 percent less likely to die of cancer during the three-year study period, regardless of how advanced the disease was (although it's worth noting that the benefits appeared to be stronger for men). The "why" isn't clear, and the study does not establish cause and effect, but researchers hypothesize that having someone who cares for you and who helps you understand your diagnosis might be behind the connection. And it's not the first study to show a link; a paper published in November 2012 found that socially isolated women were more likely to die of breast cancer than their counterparts with close social ties.

Last spring, the same researchers who looked at how social ties may influence breast cancer survival published a study that found that breast cancer patients who regularly have positive social interactions -- and who have strong support overall -- are better able to deal with the associated emotional stress and pain of cancer. "Social support helps with physical symptoms," study researcher Candyce Kroenke, an investigator with Kaiser Permanent's Division of Research said in a statement. (credit:Getty)

As Time reports, a 2011 study that followed a group of more than 1,000 older adults, (whose average age was roughly 80) found that the most social seniors had a 70 percent reduction in their rates of cognitive decline over several years, versus their least social counterparts. According to Time, the same team of researchers previously found that sociability also decreased the likelihood of becoming physically disabled. (credit:Getty)

A 2010 review of roughly 150 studies measuring the frequency of human interaction and health outcomes, found that having strong social connections can improve a person's odds of survival by 50 percent. Conversely, so-called "low social interaction" was found to be more harmful than not exercising, twice as harmful as obesity, and the equivalent of smoking 15 cigarettes a day Psych Central reported. Why? “When someone is connected to a group and feels responsibility for other people, that sense of purpose and meaning translates to taking better care of themselves and taking fewer risks,” one of the study authors told that publication.

Friends Can Help You Lose Weight.(05 of07)

When it comes to relationships and weight, the overall picture is a bit complicated: Some studies suggest that women are likely to gain weight after getting married. But as The Daily News reports, a 2012 study found that friendships can influence weight in more positive ways. High school students were more likely to lose weight, or gain it at a slower rate, if they had a slimmer group of friends. However, that same study also found the opposite to be true: students with friends heavier than they were were more likely to gain weight.What we take away from this is that surrounding yourself with people who have healthy lifestyle habits can help you emulate them. Worry less about how small or large your waistline is, and more about using your social connections to motivate yourself to exercise and eat well. (credit:Getty)
Motherhood Can Make You Act Healthier.(06 of07)

A BabyCenter poll of more than 20,000 moms found that once women entered into motherhood, 83 percent said they ate more healthfully, or were trying to improve their diets, while 65 percent said they were exercising more (or planned to) and 69 percent said they were keeping a closer eye on their mental health. That last one is extremely important, as motherhood can also have negative effects on women's mental health, namely, through postpartum depression. According to the Centers for Disease Control and Prevention, between 8 and 19 percent of women report experiencing frequent postpartum depression symptoms. (credit:Getty)

As LiveScience reports, a preliminary study presented last August found a link between marriage and reduced cardiovascular risk factors, like high blood pressure, among women specifically. And the longer the marriage, the bigger the benefits appeared to be: Every 10 years of continuous marriage was tied to a 13 percent decrease in cardiovascular risk, LiveScience explains.
