When you and your spouse gaze into one another's eyes, what's happening behind the scenes is that your heart rates are syncing up, according to research from scientists at the University of California, Davis.

"[Romantic love] is a very powerfully wonderful addiction when things are going well," said Helen E. Fisher, a biological anthropologist at Rutgers University, in a 2006 TED Talk. That's because those hormones that your brain releases when you're in love are intensely euphoric, so much so that they can make you addicted to love—and the person you're in love with.

Cuddling is good for you.

There's a reason that you love those sacred snuggle sessions so much. Every time you and your partner cuddle, it triggers the release of happiness hormone oxytocin to increase your mood and wellbeing. This phenomenon is so well-documented, in fact, that oxytocin is often referred to as the "cuddling hormone," or the "love hormone."

It eases chronic pain.

Though love isn't going to be replacing modern medicine any time soon, it could come in handy if you ever find yourself in some serious pain. One study conducted by researchers at the Stanford University School of Medicine found that the warm and fuzzy feeling creates the same response in the brain as painkillers (without any of the harmful potential side effects).

Being in a relationship positively shapes your personality.

Even the most pessimistic people can change for the better with a little bit of love in their life, at least according to the findings of one study published in the Journal of Personality. After following 245 young couples for nine months, the scientists behind the study found that being in a relationship indirectly made neurotic partners more optimistic and self-confident, presumably thanks to all the positive emotions and experiences associated with the relationship.

Honesty makes for a lasting relationship.

When it comes to love and relationships, honesty really is the best policy. One study published in the journal Personal Relationships found that the more honest couples are with one another about how their relationship is going, the more likely they are to last long-term.

Loving from a long distance actually strengthens a relationship.

People might try to tell you that long-distance relationships can't and won't work, but the research out there says otherwise. In fact, according to one study published in the Journal of Communication, not only are long-distance relationships just as successful as regular ones, but they are also more effective in building trust and satisfaction between partners.

Love and laughter go hand in hand.

If you want to feel closer to your spouse, then consider watching a new comedy series together. In one study published in the journal Personal Relationships, researchers concluded that couples who laughed together were more supportive of one another and more satisfied in their relationship compared to their chuckle-free counterparts.

Being in love cuts headache frequency in half.

If you suffer from chronic headaches and can't find anything to ease the pain, then love might just be the secret solution you've been waiting for. When researchers at the Stanford University School of Medicine gave subjects with chronic headaches a nasal spray with a dose of oxytocin, or the "love hormone," in it, they found that 50 percent of participants reported their head pain to be cut in half after four hours, with an addition 27 percent reporting no pain at all in the same timeframe.

People find it in the most unexpected of places.

Though women are often perceived as more emotional than their male counterparts, one study published in The Journal of Social Psychology found that it's actually men who tend to fall in love and say "I love you" quicker. Though they don't know for sure why this is, the researchers theorize that this is perhaps because females are more wary of getting their hearts broken.

Being in love saves you money on trips to the doctor.

When the Health and Human Services Department analyzed studies that compared marriage and health, one of the shocking things that they found was that married people reported fewer doctor's visits and shorter hospital stays. "The best logic for this is that human beings have been crafted by evolution to live in closely knit social groups," Harry Reis, PhD, co-editor of the Encyclopedia of Human Relationships, explained to WebMD. "When that is not happening, the biological systems get overwhelmed."

It helps you heal faster.

Having a loved one by your side when you're sick or injured doesn't just provide emotional support. When researchers at Ohio State University Medical Center gave married couples blister wounds, they found that the injuries healed twice as fast when the partners shared a close bond, compared to those who were openly aggressive toward one another.

It lowers your blood pressure.

Having high blood pressure, otherwise known as hypertension, has been linked to everything from heart disease to stroke.

It develops in phases.

When Harvard researchers closely examined the progression of romantic love, they confirmed what anyone who's ever experienced the emotion has known all along: It develops in phases of intensity, beginning with an obsession and gradually mellowing out into a more mature iteration of itself.

It makes you more empathetic and in tune with your emotions.

When you find someone who makes you want to be the best version of yourself, your brain responds accordingly. According to one study published in the journal Cognitive, Affective, & Behavioral Neuroscience, the social connection that comes from being in a loving relationship activates the part of the brain that's responsible for selflessness and emotional processing.

It has as much to do with scent as it does with visuals.

"For both men and women, how someone smells and whether you are innately drawn to that scent goes a long way in determining your attraction," relationship therapist Rhonda Milrad, LCSW, explained to Bustle. That's all thanks to pheromones, chemicals secreted in sweat that can spur sexual arousal.

The next time one of your friends tries to tell you that true love doesn't exist, just tell them to look up Herbert and Zelmyra Fisher. According to Guinness World Records, the late couple broke the record for the longest marriage in history back in February 2011, having been married at that point for a staggering 86 years and 290 days. As for the secret to their success, the couple once said, "There's no secret to our marriage—we just did what was needed for each other and our family."

It makes you do things you probably shouldn't…

Before she was the Queen of Norway, Queen Sonja was the daughter of a clothing merchant, dating then-Crown Prince Harald in secret. However, Harald eventually made it clear to his father that he would never get married unless the person by his side was Sonja, and the couple wed on August 29, 1968. Sometimes love can conquer all!

Red roses are the flowers of love.

Have you ever wondered why you see so many roses around Valentine's Day? That's because the bright flowers are the official favorite of Venus, the Roman goddess of love.

Love and lust light up different areas of the brain.

Don't expect your one night stand to turn into something more, at least scientifically speaking. Studies have shown that while being in love activates the regions in the brain connected to empathy, pure and unadulterated lust is connected to the similar but different areas of the brain associated with motivation and reward.

It helps you live longer.

First comes love, then comes marriage—and then comes living longer. According to one study published in the Journal of Marriage and Family, married individuals were 58 percent less likely to die over an eight-year period compared to those who had never made it to the altar.

"Quality time" isn't just a saying.

According to a study in the Personality and Social Psychology Bulletin, your personal well-being increases as you increase the time you put into your romantic relationship. (However, the benefits aren't the same if you're not already pretty happy with your partner.)

Compassion takes practice—and actually changes your brain chemistry.

Per Psychology Today, "Mindfulness and compassion meditations increase activity in brain centers connected with empathy and positive emotions, decrease activation of our fear centers, and make our brains more interconnected—a trait associated with the secure attachment pattern." In other words, the more you practice compassion for your partner, the easier it will be to understand where they're coming from and the more connected you'll feel.

Kissing serves a biological function.

Betty Everett (and Cher) were right: it's in his kiss. A study in the journal Arch Sex Behavior determined that men and women use early lip-locks to determine whether or not a potential match is right for them, though women put more emphasis on them. The study also states that kissing is also highly valued by couples in long-term relationships, as it helps to keep bonds strong.

"Love at first sight" really happens.

A 2017 study reported by Psychology Today found that "love at first sight" isn't always just a case of looking at the past with rose-colored glasses. Respondents did immediately report falling in love at first sight with potential partners, with men more likely to do so than women. Granted, those strong, initial feelings don't encapsulate all of what romantic love is, but they can prompt a person to pursue something deeper.

The butterflies will go away eventually, and that's okay.

That fluttery feeling you get in your stomach when you meet someone new isn't a sign that you'll be together forever. It's merely a physiological lust response, scientists told NBC News. So there's no need to worry if you feel calm instead of jittery when your partner walks through the door. "True love is a well-being experience that does not include nervousness or excitement," neuroscientist Nicole Gravagna, PhD explained, adding that dopamine and endorphins "drop to only mildly elevated levels compared to the pre-relationship level" after the five-year relationship mark.
